What you can do in Handsign on the web
A–Z alphabet grid
Every letter as a tappable tile with a mini mastery ring; tap for the handshape description, memory tip and your attempt history.
26 everyday signs in 5 categories
Greetings, numbers, colors, family and food — each category card shows count and mastery percentage.
Adaptive quiz
Four-choice questions weighted toward the signs you get wrong; every answer is recorded so mastery (3+ attempts at 80%) builds sign by sign.
Fingerspell any word
Type a word or name and see it as an ordered sequence of letter handshape cards.
Your own signs
Add signs you learn elsewhere with a description and tip — they join the browser and the quiz.
Progress dashboard
Mastered / in progress / not started, per-category bars, an 8-week practice heatmap, recent mastery wins and the signs that need work.

Questions
Is the web version of Handsign free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Handsign iPhone app?+
Handshapes are shown as large letter/word cards with written descriptions, not the iPhone app's vector hand illustrations. No reminders on the web — mastery streaks are computed from your quiz days instead.
