SOTA open-source dual-autoregressive text-to-speech model with rapid voice cloning, inline emotion tags, and real-time streaming inference across 80+ languages.

An MCP server giving AI agents real, undetectable browser automation — built on nodriver and Chrome DevTools Protocol to navigate sites protected by Cloudflare and other anti-bot systems for automation and testing workflows.

A next-generation documentation site generator for dbt Core projects — lineage explorer, health scoring, and full-text search for teams without access to dbt Cloud's built-in docs features.

Turn AI-written code into real apps — an open-source, self-hostable backend with Database, Auth, Storage, Memory, Functions, Assets, AI Gateway, and cron built for AI coding agents.

An open-source CLI that compiles raw documents into a structured, interlinked wiki-style knowledge base using LLMs — powered by vectorless, reasoning-based retrieval (PageIndex) instead of a vector database.

A stealth Chromium engine that corrects the browser fingerprint inside the C++ engine itself, so scrapers and browser agents stop getting blocked, with a 29-tool MCP server for AI agents.

A 100% private, on-device macOS dictation and meeting-transcription app — hold Control to talk, transcribes and pastes locally via Apple Silicon with no cloud APIs or data leaving your Mac.

A fully featured open-source mail delivery platform for sending and receiving email at scale — your own Mailgun, on your own servers.

Collaborate on high-quality AI training data with a self-hosted annotation platform built for LLMs, NLP, and multimodal models.

An Apple-Silicon-native LoRA fine-tuning tool for Gemma on text, image, and audio data — with a wizard CLI, live browser-based training visualizer, and streaming from GCS/BigQuery for datasets too large for local disk.

Rasa Open Source is a Python machine learning framework for building contextual, multi-turn chatbots and voice assistants that understand natural language and maintain conversation state.

A self-hostable AI second brain that chats with your documents, searches the web, builds custom agents, and runs entirely on your own LLM.

Self-hosted private cloud storage with AI semantic search and a pluggable multi-backend file management system.

Federated AI search and RAG across 100+ enterprise sources—no data extraction, no vector database required.

Morphik is an AI-native ingestion and retrieval engine that lets developers store, search, and reason over visually rich documents — scanned PDFs, manuals, slides, and video — without duct-taping together OCR, an embedding model, and a vector database.

A visual and textual programming platform for data prep and analysis where the node graph and the underlying Enso code are always perfectly in sync, built by an Alteryx co-founder on a GraalVM engine.

A fully local web research assistant that iteratively searches, summarizes, and refines markdown reports using any Ollama or LMStudio model—no cloud or API keys required.

Build autonomous and human-in-the-loop multi-agent AI systems with a layered, event-driven Python and .NET framework pioneered at Microsoft Research.

Computer-vision powered Python framework for building RPA bots that click, type, and read any desktop, web, or terminal UI without needing an API.

An open-source, on-device Mac desktop pet that types what you say, takes meeting notes with speaker labels, and talks back — a private alternative to Wispr Flow and Granola.
