community-writer
When a Community Notes contributor needs to add context to a disputed post, they open this open-source tool and the AI drafts note text from community-supplied material, producing a submittable draft; whether to publish stays with the contributor.
Its value is not that 'the AI can write' but that it moves part of the writing burden off volunteers while leaving the final judgment with a human — that trade-off makes it an assistant, not an automatic fact-checker. The exact input format, scoring mechanism and delivery flow still need verification.
