Tools for notes and remembering — the short answers
Every number here comes from our own daily check — not from a vendor list.
Tools for notes and remembering — how many are there?
Tablif is tracking 468 of them. 460 answered our check today, and 2 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. 460 of these 468 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?
68 of the live ones say so in their own words, and 46 let you start without making an account. Tablif records the claim the product makes; we don't verify pricing.
Any open-source options?
27 of the live ones on Tablif mention being open source.
What's the newest one?
Notebook OS — Tablif first saw it today.
Did a person actually look at these?
464 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.
