Each plan gives you a monthly allowance of memories and document pages. Two rules, identical on every tier:
A memory holds up to 1,000 words. A 2,500-word note saves as three linked memories and uses three.
A page is 2,000 characters of document text. A long report uses one page per 2,000 characters.
Longer items simply use more of your allowance. The only size limits are per item: 100,000 characters of text, and 25 MB per file.
What is metered
Memories you add — in the app, through an AI tool, or by import.
Documents you upload or your AI tool stores, in pages, against whoever saved them. A document shared into a space is metered once, to the uploader.
What is never metered
Search and recall, from the app or any AI tool, however often.
Reading, fetching or downloading documents.
Editing, archiving or deleting.
Reading what others share with you.
Anything JustOnce processes with your own AI key (a paid-plan option): forwarded emails, and files that key reads.
