Origami AI is a full-featured AI studio that runs entirely in your browser. Whether you’re turning a presentation deck into a narrated MP4, producing vertical short-form content from a single prompt, or chatting with a local AI model, everything happens on your device. Unlike cloud-based video tools, Origami AI uses WebGPU to run large language models locally, so your content never leaves your machine — and no account or subscription is required to get started.

​
What You Can Build

PDF to Video

Upload a presentation deck, generate AI narration scripts per slide, add text-to-speech voiceovers and background music, then export a polished MP4 — all inside your browser.

Shorts Generator

Describe a topic and Origami AI writes a scene-by-scene script, generates visuals, synthesizes a voiceover, and burns in captions for a complete vertical short in minutes.

Screen Recording

Record any browser tab or window with cinematic auto-zoom. Origami AI tracks your cursor interactions and applies smooth camera moves during idle periods automatically.

AI Assistant

Chat with local WebLLM models directly in your browser. Attach images or video clips for vision analysis and get instant answers — no internet connection needed after setup.

Voice Studio

Generate high-quality TTS audio from any text using Kokoro neural voices. Control speed, select from multiple voices, and export at 128, 192, or 320 kbps MP3.

File Studio

Convert images between formats and compress audio files entirely in your browser — no upload to any server required.

​
Privacy First

Your data stays on your device. Origami AI stores all API keys and project data in your browser’s IndexedDB — a local, sandboxed storage that is never transmitted to any server. When you use a cloud AI provider such as Gemini or an OpenAI-compatible endpoint, your credentials live only in your browser and are sent directly to that provider, bypassing Origami AI’s servers entirely. Local AI models run fully on-device via WebGPU. No slides, scripts, audio, or generated video frames are uploaded anywhere during processing. You can render a complete video with zero outbound network traffic after the initial model download.

How AI Works in Origami

Origami AI combines four browser-native technologies to deliver a studio-quality experience without a server-side render farm:
  • WebGPU — the modern browser graphics API that gives JavaScript direct, low-overhead access to your GPU. Origami AI uses it to accelerate both AI inference and video effects.
  • WebLLM — an open-source runtime (@mlc-ai/web-llm) that compiles large language models to run on WebGPU. It powers narration script generation, the AI Assistant, Shorts scripting, and scene analysis.
  • Kokoro.js — an in-browser neural text-to-speech engine that synthesizes natural-sounding speech audio for each slide or scene without any server round-trip. Choose from multiple voices and quantization qualities (q4 for speed, q8 for high quality).
  • FFmpeg.wasm — the industry-standard FFmpeg video toolkit compiled to WebAssembly. It composites your slides, audio tracks, music, and pan/zoom effects into a 720p or 1080p MP4 directly on your device.
Local AI features require a WebGPU-capable browser (Chrome/Edge 113+, Firefox Nightly with dom.webgpu.enabled, or Safari 18+ on macOS Sonoma). If your browser doesn’t support WebGPU, you can still use all other Origami AI tools and connect a cloud AI provider — such as Gemini, OpenAI, or any OpenAI-compatible API — via ⚙️ Settings → API as a fallback for script generation and the AI Assistant.
