We looked at four things: - **Fit**: does it do the job this list is about, for the reader it is for? - **A real product**: a live website, a clear way to sign up, and a company behind it. - **Value**: a free plan or trial where there is one, and what you get when you pay. - **Trade-offs**: where each tool is weaker, so you can choose with open eyes. Tool names, logos, pricing labels and ratings on this page come live from each tool's listing, so they stay current. Pricing changes often: check the tool's own site before you buy. ## FAQ ### What AI tools should a startup use? A lean stack covers each job once: Claude for thinking and writing, Cursor for code, Perplexity for research, Apollo for outbound, Gamma for decks and Zapier for automation. ### How can a non-technical founder build an MVP? Tools like Lovable build working web apps from plain language. Get a developer to review before real users depend on it. ### Where can I list my startup's AI product?

Tools that help you talk to customers and ship faster: a general assistant, a coding or app-building tool, and a note-taker for customer interviews.
