Check each tool's own pricing page before you decide. ## Mistakes to avoid - Building a daily workflow on a free plan without knowing its limits. - Putting work data into a free account with unclear data settings. - Assuming open source means zero cost; hosting and time still cost money. ## How we chose Every tool on this list is approved on 1ai.tools by a person, not only by an algorithm. 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 is the best free AI tool?
