An App to Help People with Prosopagnosia Recognize Movie Characters
A video player or browser extension that tags each on-screen character with a persistent visual marker (color, box, or name label) so face-blind viewers can tell them apart without relying on faces.

prosopagnosia movie character recognition app idea

Unlock with ProThe problem, in the searcher’s words
I have face blindness (prosopagnosia) and I literally cannot follow a movie or TV show because I can't tell characters apart. It's not that I'm bad with names — I genuinely cannot recognize who's on screen, especially once someone changes clothes or their hair looks different. I end up pausing constantly to ask 'wait, who is this again?' which makes watching anything with other people miserable for everyone involved.
I've tried the closest thing I could find — Amazon Prime's X-Ray feature that lists the actors in a scene — but it only works if I pause the film every time, which defeats the purpose. What I actually want is something simple: a consistent visual marker, like a colored bar or name tag, that stays attached to the same character across the whole movie so I don't have to rely on faces at all.
I'm not a developer, so I'm hoping someone can build a plugin or app for this using existing facial recognition tech — even something basic would change how I experience movies.
What the thread shows
The idea generated enough interest that two separate developers independently built working prototypes based solely on this post, showing the concept is technically feasible and appealing to builders, though corroboration of the underlying pain from other affected users is limited to the OP.
“I literally cannot tell one character from another, no matter how hard I try, or how recently they appeared.”
“The closest is Amazon Prime’s feature that lists the actors in any given scene, but that requires pausing the film.”
“The moment the clothes or hair change, I’m completely lost.”
“Im going to make it have the ability to save characters and anywhere you see them they will be shown again with a green box and a name above you can customize.”
Target customer
Who
A person with prosopagnosia (face blindness) who wants to watch live-action movies and TV shows without losing track of who each character is.
Context
Hits this problem every time they watch a film, especially with other people present, because they have no reliable way to distinguish characters once faces alone can't be used and costumes/hairstyles change between scenes.
What to build
- Upload-based or extension-based video processing with face/person detection
- Assign each detected character a persistent visual marker (colored bar, box, or label) consistent across scenes
- Manual correction/tagging so users can name or fix characters when detection is wrong
- Client-side web player as the primary interface (avoids streaming/DRM issues)
- Free first use, with a lightweight approval flow for processing new videos
Build note — Needs face/person detection plus re-identification (tracking) across scene cuts; must handle appearance changes since face alone is unreliable for the target users. Browser extensions on streaming platforms likely run into DRM/legal restrictions, which is probably why the community-built prototype (frt.uaab.dev) defaulted to client-side video upload instead.
Later, if it lands
Who’s already out there
Shows cast/character info for the current scene when the viewer pauses the video.
Gap: Requires manually pausing every time, so it doesn't provide the continuous, hands-free identification the OP needs.
A community-built web app and (unreleased) browser extension that processes uploaded video client-side; per the builder's description it aims to visually identify/track characters, with the first video processed free.
Gap: Early-stage hobby project: requires manual approval per video submission, extension not yet published, and robustness/coverage of character tracking across scenes is unverified.
Demand read
Two independent developers built working prototypes purely from reading this thread, which signals the idea is technically compelling and worth building; the OP's recurring frustration watching movies with others suggests a real, durable pain point, but no one in the thread states they would pay for a solution.
Worth digging into before you build
4 to considerNo idea is a sure thing at this stage — these are open questions worth checking yourself, not a verdict against building it.
Single Voice
Only pri_ncekin describes personally living with prosopagnosia and the movie-watching pain; no other commenter confirms having the condition themselves.
Weak Demand
No explicit willingness-to-pay statements from affected users; nightlycompiler's 'first video free' implies a future paid model but that's the builder's own plan, not evidence of user demand.
Verify Competitors
frt.uaab.dev is a live hobby-project link shared in the thread; its functionality, quality, and long-term viability are unverified.
Sensitive Domain
Prosopagnosia is a neurological condition/disability; page should get editorial review given the health/accessibility context.
