Elio
A personal AI companion platform — built, run, and used every day by its developer.
What it is
Elio is an independent software project exploring what a long-term AI companion can be: one with persistent memory, a consistent personality, and a real presence in daily life — reading alongside you, keeping a diary, remembering what matters.
It runs as a working product today: a conversational companion on Telegram backed by a memory system, together with a family of companion apps for reading and language learning.
The pieces
Companion core
An LLM-driven companion with persistent memory cards, autonomous "wandering" time (reading, writing, journaling), scheduled reminders, and multi-model routing.
Shared reading room
A private library where human and AI read the same books and exchange margin annotations — with sync from e-ink readers and a mobile reading app.
Language study tools
An Android app for intensive listening practice: video with sentence-level transcripts, tap-to-seek, live highlighting — with pronunciation feedback in the works.
