Voice AI applications

Real-time spoken conversation apps built on the Gemini Live API.

• CarBotTypeScript

  A voice-first AI companion for car rides with kids — answers questions, tells jokes, builds a memory of the family over time, and emails parents a recap after each drive.

• LegacyBot / BiographyBotTypeScript

  Voice-first life-story preservation: conducts empathetic real-time interviews with a storyteller, then transcribes and organizes their narrative for the family archive.

Libraries & utilities

Reusable packages extracted from the applications above.

• nl2timeTypeScript · Python

  Bidirectional natural language ⇄ date/time. Parses "last week" into timezone- and locale-correct intervals and describes instants back as "9pm last night", around a deterministic JSON IR. Six languages; JS and Python.

  npm · PyPI

• VoiceCommonTypeScript

  A framework for voice AI web apps on Gemini Live and Firebase — session management, transcript archival, audio recording, tool integration. Extracted from LegacyBot and generalized.

  npm

• KnowledgeCommonTypeScript

  Shared knowledge tools for Gemini Live voice apps: weather, maps, jokes, Wikipedia RAG, and date/time — with server-side proxying so API keys never reach the browser.

  npm

Agents & data

Agents that answer questions over real data pipelines.

• weatherbotPython

  Personal weather data end to end: Ambient Weather Network ingestion into Cloud SQL Postgres, queried in natural language by an ADK agent over MCP Toolbox.

• weatherbot-appTypeScript

  Mobile-first chat and voice frontend for weatherbot — React + Vite on Firebase, talking to the agent through the Gemini Live API.

Benchmarks & evaluation

Measuring what models and agents actually get right.

• agent-time-benchPython

  How well do LLM agents handle date/time in the tool calls they make and the answers they give? 10 domains × 10 scenarios, graded on both directions, across models from tiny open-weights to closed frontier.

Simulations & games

Small worlds with rules, run long enough to see what the rules actually do.

• Grammar GardenTypeScript

  Plants grown from tiny L-system recipes, in a browser. Unstable shapes collapse, sunlight and soil water decide who thrives across two climates, and bees and butterflies breed the survivors — so the field evolves forms nobody designed.

• Wind SpiritTypeScript

  A civilization sandbox where every village is run by an AI chief and the player is a spirit who sees everything and can touch almost nothing. Deterministic weekly sim, headless balance harness first.
