How this report works
Included are free assistants whose catalog entry (checked 2026-10-26) lists a very high allowance or no stated limit. Free tiers with a low cap, such as Ollie's 50 messages a month or Ka's 10 a day, are left out, and Folk (100 messages a day) has too few tests. They are ranked by the average of the tests they took. Scores come from the published score sheet and are dated 2026-10-27. 1 of the 3 ranked assistants (Nessi) carries pre-filled scores, which are placeholder estimates the site has not yet replaced with its own test runs, so treat their places as provisional. Pally and Wajo / Fo are not pre-filled.
How to choose
- Read 'no stated limit' as 'not stated', not as 'none'. Nessi says its service is free with no payments, but its page gives no allowance.
- Note what is free. Pally is listed as free, Nessi as free, and Wajo / Fo has a free tier plus an invite-only OG Fo with unlimited tasks.
- Compare scores before cost: Pally (8.1) and Wajo / Fo (7.1) are not pre-filled, while Nessi's 5.4 is.
