Frametell (帧言, zhēn yán) turns your ideas and your material into vivid explainer videos with pages that move. One sentence is enough to start ("explain the uncertainty principle"), or you can hand it notes, documents, PDFs, slides and images. A director agent first drafts a storyboard for you to sign off on. Then it writes the narration, voices it, draws each page and checks its own work. You get a 1080p video, with subtitles and publishing notes.
It's built for knowledge creators who explain history, science, technology, investing, psychology or books, and who'd rather tell the story than learn video editing.

One run in the desktop app, condensed to a minute: a question, a storyboard to sign off, narration, voice, five pages and the finished film (72 s, made in 12 min 52 s for $1.59).
Two films Frametell made end to end in English: storyboard, narration, an ElevenLabs voice, every page and the render. Click a picture to watch (with sound).
Frametell makes Chinese films just as well; see the Chinese README for two of them.
Built-in styles: warm-story, study, chalkboard, whiteboard, tech-dark.
macOS on Apple Silicon: download the .dmg from the latest release, open it and drag Frametell into Applications. The app is signed and notarized by Apple. You also need Chrome, Edge or Chromium installed; Frametell uses it to draw and render the pages.
When it opens, add a key for a model provider (Anthropic, OpenAI, Google, OpenRouter …) under Settings, and an ElevenLabs key for the voiceover.
Windows and Intel Macs don't have an app yet. Until they do, run Frametell from source.
You need Node.js 22.19 or later, pnpm, and Chrome, Edge or Chromium installed. FFmpeg is bundled.
git clone https://github.com/sitor-ai/frametell.git && cd frametell
pnpm install && pnpm build
export ANTHROPIC_API_KEY=... # or OPENAI_API_KEY, GEMINI_API_KEY …
export ELEVENLABS_API_KEY=... # optional, for the voiceover (VOLCENGINE_TTS_API_KEY for Chinese voices)
# Open the studio in your browser
node apps/cli/dist/cli.js serve
# Or make a video straight from the command line
node apps/cli/dist/cli.js run notes.pdf --style warm-story --duration 60 --lang en
