Gradium and SurrealDB demo a fully on-device research agent with memory and streaming TTS

mattturck · x · 2026-11-05

Gradium and SurrealDB open-sourced a demo research agent built on Phonon (on-device TTS) and SurrealDB Agent Memory, running entirely on-device.

How it works:

Collect: you type or paste notes on a topic
Store: each note goes into SurrealDB Agent Memory under the project scope (project/<id>), which extracts entities and facts
Research: the agent plans questions, recalls evidence from memory, reasons via Agent Memory chat, and writes findings back
Output: it writes a brief that Phonon reads aloud sentence-by-sentence on device while the brief is still streaming

Built with Expo (React Native) + TypeScript; code available on GitHub (surrealdb/surrealdb-gradium-phonon).
