What to know▼
How it works
A pre-commit git hook that matches your AI chat session transcripts to the files you've staged, then uses the Claude Code CLI to distill the reasoning behind the change into an intent document saved in docs/intents/ and staged into the same commit.
What's different

Tools for understanding code and keeping docs current — the short answers
Every number here comes from our own daily check — not from a vendor list.
Tools for understanding code and keeping docs current — how many are there?
Tablif is tracking 67 of them. 64 answered our check today, and 3 we couldn't reach — we don't claim those are dead.
Which ones are still maintained?
Tablif knocks on every door once a day and records the answer. 64 of these 67 responded on the latest run, so that number is what "still here" means on this page — not a review score.
Are any of them free?
6 of the live ones say so in their own words, and 3 let you start without making an account. Tablif records the claim the product makes; we don't verify pricing.
Any open-source options?
4 of the live ones on Tablif mention being open source.
What's the newest one?
Onset — Tablif first saw it 4 days ago.
Did a person actually look at these?
64 of them Tablif opened and read, then wrote a one-line summary in our own words instead of reusing the founder's tagline. The rest carry keyword labels we haven't confirmed by reading yet — and we say so rather than hiding it.
