Est. 2026 · A modern rag
Your knowledge,
played by ear.
RAGTIME compiles your documents into a private on-device LLM. Customize the persona, upload your knowledge, and download an app that runs fully offline on Android or iOS — no internet, no leaks, no subscription to a stranger's cloud.
Free demo build · Bring your own PDFs, notes, or Markdown.
Three movements
How the song is written
Upload your rag
Drop in PDFs, text, or Markdown. Your notes, manuals, journals, playbooks — anything you want the companion to know.
Tune the persona
Give your companion a name, a voice, and a purpose. A gentle tutor, a stoic butler, a road-trip DJ.
Compile & download
We stitch the model, your knowledge, and the runtime into a single installable app. Sideload it and go dark.
Built for people who prefer acoustic.
Fully offline
The installed app never phones home. Your data stays on the device.
Small footprint
Quantized to run on mid-range phones without melting the battery.
Your voice
Custom system prompt, tone, and refusal style — no generic assistant feel.
RAG built-in
Semantic retrieval over your documents ships inside the app package.
No subscription
Pay to build, keep the artifact. No usage meter, no cloud calls.
