24 Free AI Tools to Start and Grow Your Business (2026)

Starting a business used to require a small army of professionals. You needed a copywriter for your website, a designer for your brand, an accountant for your invoices, and a lawyer for your policies. For solo founders and bootstrapped startups, the cost of all that expertise was often a barrier that kept great ideas stuck in notebooks.

In 2026, AI tools have leveled the playing field in a way that would have seemed impossible just a few years ago. A single founder working from a kitchen table now has access to capabilities that rival what entire departments used to deliver. The best part? Many of these tools are completely free to use.

At FounderKit, we have built a suite of 24 AI-powered tools specifically for entrepreneurs. Each one solves a real problem that founders encounter at every stage of building a business — from choosing a name on day one to writing marketing copy as you scale. No signup is required to start using them. No credit card. No complicated onboarding. You describe what you need, and the tool delivers.

This guide walks through every tool we offer, organized by category, so you can find exactly what you need for wherever you are in your business journey.

All tools are free to use 5 times per day with no signup. Upgrade to Pro for unlimited access.

Naming: Build a Brand That Sticks

Every business starts with a name. It is the first thing customers see, the first thing they remember, and often the first thing they judge. A strong name builds trust before you ever say a word about your product. A weak one creates friction at every touchpoint — from word-of-mouth referrals to search engine results.

The challenge for most founders is that naming feels subjective and open-ended. You can brainstorm for weeks and still feel uncertain. AI naming tools solve this by generating dozens of targeted options in seconds, grounded in linguistic patterns and branding best practices, so you can move from ideation to decision faster.

Business Name Generator

The Business Name Generator takes a short description of your business idea and produces a curated list of creative, brandable name suggestions. Each suggestion comes with an explanation of why the name works, covering factors like memorability, tone, and market positioning. Whether you are starting a SaaS company, an e-commerce store, or a consulting practice, this tool gives you a strong starting point that would otherwise take hours of brainstorming.

Domain Name Generator

Finding a business name is one thing. Finding one with an available domain is another challenge entirely. The Domain Name Generator helps you discover domain name options that are actually available to register, combining your business concept with smart variations and extensions. It saves you from the frustrating cycle of falling in love with a name only to discover that the .com has been parked since 2009.

Tagline & Slogan Generator

A great tagline distills your entire value proposition into a single memorable phrase. The Tagline and Slogan Generator creates concise, punchy taglines based on your business description and the message you want to convey. Use it when you are building your website header, designing business cards, or crafting social media profiles — any moment where you need to communicate what you do in just a few words.

If you are working through the full branding process, our Brand Identity Kit in the premium templates store pairs perfectly with these naming tools to help you build a cohesive brand from scratch.

Writing: Communicate Like a Pro

Clear, persuasive writing is the engine behind almost every part of your business. Your emails need to get opened. Your product pages need to convert browsers into buyers. Your press outreach needs to sound credible and newsworthy. For most founders, writing is not their core skill — and hiring a professional copywriter is expensive.

AI writing tools do not replace your voice or your expertise. What they do is eliminate the blank page problem. They give you a solid first draft that you can shape and refine, cutting your writing time dramatically while keeping the output professional.

Email Subject Line Tester

Your email subject line is the gatekeeper. If it does not grab attention in a crowded inbox, the rest of your carefully crafted email never gets read. The Email Subject Line Tester analyzes your subject line and predicts its likely open rate based on factors like length, word choice, emotional impact, and urgency. Run your subject lines through it before every campaign to catch duds before they cost you clicks.

Product Description Writer

Writing product descriptions that actually sell is harder than it looks. You need to balance features with benefits, speak to your customer's pain points, and maintain a consistent brand voice — all in a few short paragraphs. The Product Description Writer generates compelling product copy from your basic inputs, structured to highlight what matters most to buyers. It is especially useful if you are launching an e-commerce store with dozens of products that each need unique, persuasive descriptions.

Press Release Generator

Getting media coverage can be transformative for a young business, but journalists receive hundreds of pitches a day. A poorly formatted press release gets deleted instantly. The Press Release Generator creates properly structured press releases that follow AP style and industry conventions, covering your who, what, when, where, and why in the format journalists expect. Use it for product launches, funding announcements, partnerships, or any milestone worth sharing.

For founders who send regular email campaigns, check out our Email Marketing Templates for pre-built sequences that pair well with the subject line tester.

Finance: Stay on Top of Your Numbers

Financial clarity is not optional — it is survival. Founders who understand their margins, track their costs, and invoice professionally get paid faster, make better decisions, and build businesses that last. Yet financial tasks are among the most procrastinated in small business because they feel tedious and intimidating.

These tools make the financial side of running a business faster and less painful. They handle the formatting and calculations so you can focus on the strategy.

Invoice Generator

Getting paid should not require a degree in graphic design. The Invoice Generator creates clean, professional invoices from simple inputs like your business details, client information, line items, and payment terms. The output is formatted and ready to send, giving your business a polished, credible appearance regardless of its size. Use it every time you bill a client, and stop spending time wrestling with spreadsheet templates.

Profit Margin Calculator

Understanding your margins is fundamental to pricing correctly and staying profitable. The Profit Margin Calculator takes your cost and revenue figures and instantly shows you gross margin, markup percentage, and net profit. It is invaluable when you are setting prices for a new product, evaluating whether a project is worth taking on, or comparing the profitability of different offerings in your lineup.

Startup Cost Estimator

Before you invest your savings or pitch investors, you need a realistic picture of what it will cost to get your business off the ground. The Startup Cost Estimator walks you through the major expense categories for your type of business and produces a detailed cost breakdown. It helps you avoid the common trap of underestimating costs, which is one of the top reasons new businesses fail in their first year.

If you are building financial projections for investors, our Financial Model Templates provide ready-made spreadsheets that complement these calculators with detailed forecasting.

SEO: Get Found by Your Customers

You can build the best product in the world, but it does not matter if no one can find you. Search engine optimization is how potential customers discover your business when they are actively looking for what you offer. The problem is that SEO feels technical and opaque to most founders, and hiring an SEO consultant can cost thousands per month.

These tools demystify the core elements of SEO and give you actionable outputs you can implement immediately, no technical background required.

SEO Meta Description Generator

Your meta description is the short text snippet that appears below your page title in search results. It is your two-sentence sales pitch to get someone to click. The SEO Meta Description Generator writes optimized meta descriptions that incorporate your target keywords naturally while compelling searchers to visit your page. Use it for every page on your website — homepage, product pages, blog posts, and landing pages.

Blog Title Generator

The title of your blog post determines whether someone clicks through from search results or scrolls right past. The Blog Title Generator creates engaging, SEO-friendly headlines based on your topic and target keywords. It produces multiple variations so you can choose the one that best balances search optimization with click appeal. A strong title can be the difference between a post that gets ten views and one that gets ten thousand.

Keyword Research Tool

Keyword research is the foundation of any SEO strategy. The Keyword Research Tool helps you discover what your potential customers are actually searching for, identify low-competition opportunities, and understand search intent behind different queries. Use it before writing any content to make sure you are targeting terms that will actually drive relevant traffic to your site.

For a deeper SEO strategy, our SEO Playbook for Founders in the templates store provides a step-by-step framework that builds on the insights these tools generate.

Social Media: Build Your Audience

Social media is where your brand personality comes to life and where many of your customers will first encounter you. But maintaining a consistent, engaging presence across multiple platforms is one of the most time-consuming tasks a solo founder faces. Each platform has its own culture, format, and best practices.

These tools handle the creative heavy lifting so you can show up consistently without spending hours crafting every post.

Social Media Bio Writer

Your social media bio is prime real estate. In just a few lines, it needs to tell visitors who you are, what you offer, and why they should follow you — all while matching the tone of each specific platform. The Social Media Bio Writer crafts optimized bios for platforms like Twitter, Instagram, LinkedIn, and TikTok, each tailored to that platform's conventions and character limits. Update your bios whenever you pivot, launch something new, or simply want a fresh take.

Hashtag Generator

Hashtags expand your reach beyond your existing followers, but using the wrong ones is a waste of effort. The Hashtag Generator finds relevant, high-engagement hashtags based on your content topic and target audience. It balances popular broad hashtags with niche-specific ones to maximize discoverability without drowning in competition. Use it before publishing any post to make sure your content gets in front of the right eyes.

Social Media Post Generator

Writing platform-specific posts from scratch every day is exhausting. The Social Media Post Generator creates ready-to-publish posts tailored to the platform you choose — whether that is a concise tweet, a longer LinkedIn thought piece, or an engaging Instagram caption. Feed it your topic or key message, and it produces copy that fits the platform's style and your brand voice. It is perfect for batch-creating a week's worth of content in a single sitting.

Our Social Media Content Calendar Templates pair well with these tools if you want a structured plan for your posting schedule.

Productivity: Work Smarter on Strategy

Running a business is not just about execution — it is about thinking clearly. The strategic work of planning content, analyzing your competitive position, and articulating your purpose tends to get pushed aside by day-to-day urgencies. But founders who invest time in strategic clarity make better decisions and build stronger businesses.

These tools structure your thinking and accelerate the strategic work that often gets neglected.

Blog Post Outline Generator

A well-structured outline is the difference between a blog post that flows logically and one that meanders without a point. The Blog Post Outline Generator creates detailed content outlines based on your topic, target audience, and key points you want to cover. It organizes your ideas into a clear hierarchy of sections and subpoints, giving you a roadmap that makes the actual writing dramatically faster. Use it every time you sit down to create content.

SWOT Analysis Generator

A SWOT analysis — strengths, weaknesses, opportunities, and threats — is one of the most useful strategic frameworks in business. The SWOT Analysis Generator produces a comprehensive analysis based on your business description and market context. It surfaces factors you might not have considered and presents them in a structured format that makes it easy to identify your priorities. Run one quarterly, or whenever you are making a major business decision like entering a new market or launching a new product line.

Mission Statement Generator

Your mission statement defines why your business exists beyond making money. A clear, compelling mission attracts customers who share your values, guides internal decision-making, and differentiates you from competitors who sell similar products. The Mission Statement Generator helps you articulate your purpose in concise, powerful language. It is especially useful in the early stages when you are still crystallizing your vision, or later when you need to update your messaging to reflect how your business has evolved.

If you are working through a full business plan, our Business Plan Templates provide comprehensive frameworks that build on the outputs from these strategic tools.

Legal: Protect Your Business

Legal documents are one of those things every business needs but nobody enjoys creating. Privacy policies, terms of service, and refund policies are required for any online business, and not having them exposes you to real liability. But hiring a lawyer to draft these from scratch can cost hundreds or even thousands of dollars — money that early-stage founders often cannot spare.

These generators produce solid starting-point documents based on your specific business type and practices. They are not a substitute for legal counsel on complex matters, but they cover the fundamentals that every business needs in place from day one.

Privacy Policy Generator

If your website collects any user data — and almost every website does, even if it is just analytics cookies — you need a privacy policy. Many advertising platforms and payment processors require one before they will approve your account. The Privacy Policy Generator creates a comprehensive privacy policy based on the types of data you collect, how you use it, and what third-party services you integrate with. It covers the key requirements that regulations like GDPR and CCPA expect, giving you a compliant foundation.

Terms of Service Generator

Terms of service define the rules of engagement between your business and your users. They limit your liability, establish intellectual property rights, and set expectations for acceptable use. The Terms of Service Generator produces a tailored document based on your business type, whether you sell products, provide services, or operate a SaaS platform. Having proper terms in place protects you from disputes and gives your business a professional, established appearance.

Refund Policy Generator

A clear refund policy is not just a legal requirement for many businesses — it is a trust signal that directly impacts conversion rates. Customers are more likely to purchase when they know exactly what happens if they are not satisfied. The Refund Policy Generator creates a clear, fair refund policy based on your business model and preferences, covering timeframes, conditions, and process. Use it to build customer confidence and reduce support inquiries about returns.

For founders who need more comprehensive legal document coverage, our Legal Document Bundle includes additional templates for NDAs, contractor agreements, and other common business documents.

Marketing: Tell Your Story and Win Customers

Marketing is how you translate what your business does into a message that resonates with the people who need it. The challenge for founders is that marketing requires you to step outside of your own perspective and see your business through your customer's eyes. That shift in perspective is where many solo founders struggle.

These tools help you craft the core marketing assets that every business needs — a compelling pitch, a clear understanding of your audience, and a value proposition that sets you apart.

Elevator Pitch Generator

You get sixty seconds — sometimes less — to explain your business in a way that makes someone want to learn more. The Elevator Pitch Generator creates a concise, compelling pitch based on your business concept, target audience, and key differentiators. It structures your message using proven storytelling frameworks that lead with the problem, present your solution, and end with a clear call to action. Use it before networking events, investor meetings, pitch competitions, or anytime you need to articulate your business quickly and persuasively.

Customer Persona Builder

Trying to market to everyone is the fastest way to reach no one. The Customer Persona Builder helps you define detailed profiles of your ideal customers, including their demographics, pain points, motivations, and buying behavior. These personas inform every marketing decision you make — from the language on your homepage to the channels you invest in to the features you prioritize in your product. Build personas early and revisit them as you learn more about who actually buys from you.

Value Proposition Generator

Your value proposition is the single most important statement on your website. It answers the question every visitor asks within five seconds of landing on your page: why should I care? The Value Proposition Generator helps you articulate what makes your business uniquely valuable in clear, customer-focused language. It cuts through the jargon and generic claims that plague most business websites and gets to the heart of why someone should choose you over every alternative, including doing nothing at all.

For founders building out their full marketing strategy, our Marketing Strategy Templates provide campaign frameworks and messaging guides that extend the work these tools start.

How to Get the Most Out of These Tools

Having access to 24 free tools is powerful, but using them strategically is what creates real results. Here are a few tips for getting the most value out of the FounderKit toolkit.

Start with your biggest bottleneck. Do not try to use all 24 tools in one sitting. Identify the task that is slowing you down the most right now — whether that is writing product descriptions, creating invoices, or figuring out your SEO strategy — and start there. Build momentum with one win before expanding.

Use outputs as starting points. AI-generated content is a first draft, not a final product. The tools give you a strong foundation, but your personal knowledge, voice, and judgment are what make the output truly yours. Spend your time refining and personalizing rather than staring at a blank page.

Combine tools for compound results. The tools are designed to work together. Use the Keyword Research Tool to identify your target keywords, then feed those into the Blog Title Generator and SEO Meta Description Generator. Use the Customer Persona Builder to define your audience, then reference those personas when using the Social Media Post Generator or Product Description Writer. The more context you bring to each tool, the better the output.

Revisit tools as your business evolves. Your business at launch is different from your business six months in. Rerun your SWOT analysis quarterly. Update your tagline as your positioning sharpens. Refresh your social media bios as you hit new milestones. These tools are not one-and-done — they are part of your ongoing workflow.
