Questions
Are these AI tools really free?
Every tool on this page is either completely free or open source. Many freemium tools also have generous free plans; you can find them on the Freemium filter of the main index.
What is the difference between free and open source?
Free tools cost nothing to use but are run by a company. Open-source tools publish their code, so you can inspect, modify and self-host them.
How often is this list updated?
New tools are checked every day and added after a manual review. Links are checked every week.
