RAGTIME public beta: help test a document-based offline Android AI

Hi everyone, I’m Rui from R&D Streams.

RAGTIME builds an Android AI companion from PDFs, text, or Markdown. You choose its persona, build and download the APK through the website, then use the installed companion offline. Android is available; iOS is planned.

Try the beta: https://ragtime.live

I’m looking for feedback on three things: whether setup is clear, whether answers use the uploaded documents appropriately, and how the app performs on different Android phones. If you report a performance issue, please include your phone model.

If creative tools, games, or business utilities are closer to your interests, our other beta projects are collected here: https://ragtime.live/projects. Examples include Sonic Fractals, Brand Builder Plus, and Letter Bingo Bash.

What worked for you, and what should we improve first?
