Frameglass
Plan, make and keep short AI videos.
Frameglass is a Mac app for making short videos with ByteDance's Seedance models. Plan the shots, gather reference images and audio, write the prompt, and it runs the job on your own OpenRouter or fal account, then downloads the video and keeps it with the project.
- Mac
- macOS 26 or later
- Bring your own keys
What it does
People who make short AI videos and want one place on the Mac to plan a clip, keep its references together and keep the results.
- Video projects
- Each video keeps its own script, assets, settings, saved setups and results.
- Script planner
- A brief and timed shot cards (camera, action, audio, continuity) that turn into one prompt.
- Asset library
- Import images and audio, search them and pick references. Nothing is uploaded on import.
- Generate
- Pick provider, model, resolution, aspect ratio, length and whether to make audio.
- Saved setups
- Save a prompt, references and settings under a name and bring them back later.
- Careful with money
- A request that might have gone through is never resent automatically, so you don't pay twice.

What you need
- OpenRouter or fal
- An account with credit and an API key from at least one. Each video is a paid job on your account.
Rough edges
This is a tool I built for myself and use every day, not a polished product.
- Needs macOS 26 (Tahoe) or later.
- Only the Seedance models on OpenRouter and fal.
- No accounts, sync or cloud backup: everything stays in the app's folder on your Mac.
- Real paid runs haven't been tested end to end as much as I'd like.
How it's built
For the technically curious.
- App
- Swift 6 and SwiftUI, sandboxed, with no outside libraries.
- Storage
- SwiftData for projects and history. Keys in the macOS Keychain.
- Providers
- OpenRouter's video API and fal's queue, called directly.
- Tests
- 49 tests covering imports, requests, recovery and the Keychain.
