AI Tool Collections
Grouped by what usually decides the choice: price, licence, API access and who the tool is for.
Category pages group tools by what they do. These collections cut the other way — across every category at once — so you can start from a constraint instead of a topic: something free, something you can self-host, something with an API, or something suited to studying.
Free AI Tools
These tools are free to use outright — not free trials, and not paid products with a limited free tier. Tools that merely include a free plan alongside paid ones are listed separately, because the difference matters when you are choosing something to rely on.
293 toolsOpen Source AI Tools
Every tool here is open source, which means you can read how it works, adapt it, and in many cases run it on your own hardware instead of sending your data to someone else's server.
461 toolsAI Tools with an API
These tools expose an API, so you can call them from your own code rather than working through their interface. This is the list to start from if you are building AI into a product, a script or an automation.
1,084 toolsAI Tools with Free Trials
Each of these paid tools offers a free trial, so you can test it on your own work before paying. That matters more with AI tools than with most software, because output quality depends heavily on your specific task.
445 toolsAI Tools for Students
Tools in this collection are aimed at studying — summarising dense material, turning notes into practice questions, explaining a concept a different way, and keeping research organised.
267 toolsAI Tools for Business
These tools are aimed at business use — marketing and content, customer communication, reporting, and the kind of repetitive operational work that is well suited to automation.
