Memorandai Go is a helpful pocket companion: a place for your notes, ideas, and to-dos, with a few memory-themed games, plus Helios — an optional AI chat assistant. Bring your own API keys to enable Helios using keys you generate from Anthropic, OpenAI, Google, or xAI. Your conversations go straight from your phone to the provider you choose, on their terms — never through our servers (because we don't have any). As the mobile accompaniment to Memorandai for desktop, Memorandai Go can be synced with your computer for a richer experience on both platforms. Pair your phone by scanning a QR code, and your key context syncs both ways over local Wi-Fi; anything you capture on the go folds back into your archives, with no cloud of our own in the middle. What's inside: - Notes, To-Dos, and Ideas: capture thoughts before they're gone - Flash Cards: create and shuffle cards for active learning - The Oracle: ask a question, get an answer from the sun - Games: Memory Match, Echo Match, Constellations, Sun Run, and Letter Garden - Helios: an AI companion powered by your own API keys (optional) - Book Club: read alongside AI in a book club of two (optional) - Mobile Sync: local network pairing with the desktop version of Memorandai (optional) The app is as private as possible by design: Memorandai Go has no cloud user accounts of its own, shows no ads, and has no interest in tracking you or your data. Your data should be your own; own your own context.
