Duolingo for sign language: does it exist?

Who already tried this

What's the crossover

A streak-based daily sign language habit app. Because Lingvano and ASL Bloom already do this, the open angle is narrower: an under-served sign language, or a narrow job such as family members of a Deaf child learning together.

Demand check

Publish a signup page for the narrow angle, such as daily sign language for parents of a Deaf child, and share it in the parent groups you can reach. Over the next couple of days, count signups and replies against the visits. If almost nobody signs up, the existing apps already cover the need.

Build plan

• Start: pick a sign language and an audience. Record a starter set of signs with a fluent signer you pay and credit.
• Next: ship a web app with a daily lesson, a streak counter, and a short quiz where the learner picks the sign shown in a clip.
• Then: add a reminder email and a simple paid plan behind a free opening unit.
• After that: invite the signup list, watch streak retention, and fix the lesson where people drop off.

Copy the build prompt

Build a small web app for learning a sign language through a daily habit. Each lesson shows short video clips of a fluent signer, then asks the learner to pick which word a clip shows. Track a daily streak, show progress per unit, and send a reminder email when the learner has not practiced today. Keep the opening unit free and put later units behind a paid plan. Store users, lessons, streaks and plan status in a database. Use plain, accessible HTML with captions on every clip.

Risks and unknowns

• Lingvano and ASL Bloom already sell this habit loop, so a general ASL app starts behind.
• Lessons without fluent or native signers are likely to teach errors and lose trust.
• Duolingo could add a sign language course; no announcement was found as of October 2026 8.

1. 1. The score runs to 100. Evidence is 3 for each fetched fact, capped at 25. Mechanism fit is 5 for each counted mechanism, capped at 20. Demand is 4 for each counted signal, capped at 20. Openness starts at 20 and loses 5 for each verified direct match, and it stops at 0. Build ease starts at 15 and loses 5 for each sourced hard requirement, and it stops at 0, and only when that review is recorded. A page under 50, and any thin page, is left out of the index. Weights are this site's rule, recorded in the project specification on 19 Oct 2026. A judgment step has to agree when the two parents are checked in both orders.
