About Rubidu
Private AI voice assistant for Mac, fully on-device. App, source and brand.
Rubidu is a finished macOS menu-bar assistant you talk to. It hears you, acts on your Mac and answers in a natural voice, with everything running on the Mac: no server, no account, no API bills, and it works with the Wi-Fi off. What it does: Talk to your Mac: wake word, hold-a-key or type. Opens and arranges apps, clicks buttons by name, types into any app, music, volume, Wi-Fi, timers, reminders, calendar, mail drafts, a clipboard shelf. Writes and reads: formatted notes and tables into Notes, Pages, Word or any text box; reads the screen and PDFs and answers questions about them; a study partner that explains and quizzes you on a document. A voice with personality: natural local voice, including a clone of your own; seven personalities, games, daily challenges, a recap of your day. It pauses your music while it listens. Can't be tricked by what it reads: text on a screen, page or document never becomes a command. Every action passes a policy check; risky ones need a spoken yes. Tech: Qwen3-1.7B on Apple MLX, Apple's on-device speech recognition with whisper.cpp behind it, Pocket TTS for the voice. Python with a Swift helper, about 70,000 lines, 5,391 automated tests, 51 design records, commercial-safe licences only (no GPL) with a full bill of materials. Apple silicon, 16 GB, macOS 26.2 or later. What you get: the app and installer, full source code with its git history, the brand, website, demo videos, X, Instagram and YouTube accounts, the release pipeline, tests and documentation. Rebranding is one file. Honest status: no revenue or users yet. You are buying a finished, well-tested product, not a business. Not notarised (your Apple Developer ID adds that). Why I'm selling: I built it to the point it works well, and I'm selling it to fund a machine for local AI work. 90 s demo: https://youtu.be/UpJDSnQk7JM Full 12 min demo: https://www.youtube.com/watch?v=pEF-2vNGCJI

Next step: <p>- Ship it under your own brand: rebranding is one file, then add your Apple Developer ID to notarise it.</p><p>- Charge for it: a one-time Mac app price or a Pro tier (custom voices, personalities, study tools).</p><p>- Add it to an existing Mac app or local-AI product as its voice front end.</p><p>- Grow it: try a bigger model on 32 GB Macs; the architecture already separates rules, model and tools.</p>
