Source code for the GitHub Copilot Chat extension in VS Code: inline chat, an agent mode that plans and edits files autonomously, next-edit suggestions, and MCP integration. Open-sourced so developers can study how Copilot connects to an editor.
Stores a pruned proximity graph instead of all embeddings, recomputing vectors on demand at query time. A 60M-doc index takes 6GB, not 201GB (97% less), at comparable recall. Powers private local RAG over files, mail, chat, and browser history.
Extracts structured data from unstructured text with LLMs, mapping every extraction to its exact character span in the source for visual review. Uses few-shot examples, schema enforcement, and multi-pass chunking to handle long documents.
Spec-driven agentic dev platform that turns a prompt into requirements, a design doc, and sequenced tasks before any code is written, then implements from the spec. Runs across IDE, CLI, web, and mobile; validates output with property-based tests.
Cross‑platform AI client for web, desktop, and mobile that lets teams pick model providers, run local or on‑prem inference, and keep data self‑hosted — aimed at enterprise self‑deployment to avoid vendor lock‑in.
Coordinates specialized AI agents — developer, browser, document, multimodal — running in parallel on your desktop to automate multi-step work. Runs fully local via Ollama, vLLM, or LM Studio, with built-in MCP tools and human-in-the-loop checkpoints.
Indexes any repo into a knowledge graph of dependencies, call chains, and execution flows, then feeds it to AI coding agents via MCP so they stop missing context. Ships as a CLI plus a zero-install browser graph explorer with chat.
Wraps 20+ AI coding CLIs — Claude Code, Codex, Gemini CLI, Cursor Agent — in one cross-platform desktop app so agents run file, document, and data tasks without a terminal. Adds parallel multi-agent runs and cron-scheduled jobs for unattended work.
Displays model info, token usage, git branch and other runtime metrics as a customizable Powerline-style status line for Claude Code CLI. Includes an interactive TUI, many widgets (usage, speeds, block timer), OSC8 links, and cross-platform support via npx/bunx.
Chat-driven tool that clones any website and converts it into a working modern React app. Uses a Firecrawl backend to orchestrate multiple LLM providers and offers a fast sandbox preview workflow (Vercel or E2B) for rapid prototyping and iterative edits.
A TypeScript agent harness split into composable npm packages: a unified LLM API across OpenAI, Anthropic and Google, an agent runtime with tool calling and state, a self-extensible coding-agent CLI, and a differential-rendering terminal UI library.
Turns OpenAI Whisper into a live streaming transcriber: audio flows in over WebSocket and text returns word-by-word instead of after full utterances. Adds SimulStreaming and LocalAgreement decoding, Silero VAD, and speaker diarization, all self-hosted.
