Why Signpost
Three things every ASL app has been missing.
Real-time feedback
Signpost grades every sign as you perform it. This enables you to start learning ASL at an accelerated rate compared to traditional learning measures.
A built-out ASL curriculum
We don't just show important words, we teach culture and meaning alongside the words. Start with the ASL alphabet and fingerspelling and work up to full conversational American Sign Language, lesson by lesson.
Free forever, actually
You can visit every single one of our units for free, forever. You can learn ASL for entirely free as long as you want! Plans are cosmetic and for helpfulness only, not for limiting learning behind paywalls.
How it works
From zero to your first signed conversation in three steps.
Signpost is built for self-teaching. You won't need an instructor, a classroom, or any equipment beyond a webcam.
- 01
Open the app
Visit demo.signpostasl.com in any modern browser. Hand tracking runs locally on your device, so a webcam is all you need to start. Or, you can opt for traditional learning methods using videos.
- 02
Turn on your webcam
Allow camera access and start signing. Our machine learning model watches every gesture and tells you within 100ms whether your hand shape, position, and motion match the target sign.
- 03
Work through the curriculum
Move from the ASL alphabet to fingerspelling drills to conversational signing at your own pace. Progress is tracked automatically against a standardized fluency benchmark.
For schools
Drops into the LMS your school already runs.
Signpost ships with full LTI 1.3 support. Teachers place lessons straight into their course gradebooks, and students roster automatically into the tools the school already uses.

Signpost lets you learn American Sign Language online using just a webcam. Our machine-learning-powered computer vision watches your hand signs in real time and gives instant feedback on your form. Start with the ASL alphabet and fingerspelling, then work through a structured curriculum to full conversational ASL at your own pace.
Yes. Signpost offers a free demo that requires no sign-up. Just open the app, turn on your webcam, and start signing. The machine learning model gives you real-time feedback immediately.
A computer or phone with a webcam and any modern browser. The demo runs in the browser itself, so there is nothing to download or install.
Most ASL apps only show you videos to copy. Signpost uses machine-learning-powered computer vision to watch your actual hand signs and correct your form in real time, so it works like a personal ASL tutor that is available 24/7 with under 100 milliseconds of feedback delay.
Yes. Signpost is built for beginners with zero ASL experience. The curriculum starts with the ASL alphabet and fingerspelling, then moves to common signs and conversational ASL at your own pace.
Most learners can pick up the ASL alphabet and basic fingerspelling in a few hours. Becoming conversational in American Sign Language usually takes 6 to 12 months of regular practice. Because Signpost gives feedback on every sign, learners typically progress faster than they would using video-only courses.
ASL is not harder to learn than a spoken second language, but it uses your hands, face, and body instead of your voice, so it feels new at first. The biggest obstacle for most beginners is not knowing whether they are signing correctly. Signpost solves that by giving instant feedback on every gesture.
Yes. Signpost is designed for self-teaching at home. The machine learning model plays the role of a tutor by watching your signs through your webcam and correcting your form so you don't build bad habits.
Yes. The first lessons in Signpost cover the full ASL alphabet and fingerspelling drills. You can practice each letter and the machine learning model will tell you in real time whether your hand shape matches.
Your privacy is our top priority. All hand tracking runs entirely in your browser. Your webcam feed is never sent to our servers, recorded, or stored. The only data we save server-side is numerical hand landmark coordinates (joint positions, not images or video) used to improve our recognition models. No webcam footage ever leaves your device.
Sign your first ASL letters in under five minutes.
Open the demo, turn on your webcam, and start fingerspelling. The machine learning model corrects every letter in real time. No sign-up, no download.
