Fit
Whether a tool is built for this job, a strong fit for it, or
able to do it without that being its focus.
Free plan
Whether there is a tier you can keep using rather than a
trial that expires.
The order
Fit first, then a free plan, then alphabetical. There is
no score, no weighting we decline to publish, and nothing on this site a company can buy.
Questions
What is the best ai for note taking?
There is no single answer, which is why this page lists 6 rather than one: Notion, Otter.ai, Gemini Notebook, Fathom, Notion AI, Petal. 4 of them are built for this kind of work rather than able to do it. Start with a free one.
Which of these have a free plan?
6 of the 6: Notion, Otter.ai, Gemini Notebook, Fathom, Notion AI, Petal. Free means a real free tier you can keep using, not a trial that expires.
How was this list chosen?
By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
