    AnythingLLM

    AnythingLLM

    The all-in-one Desktop & Docker AI application with full RAG and AI

    A full-stack application that enables you to turn any document, resource, or piece of content into a context that any LLM can use as references during chatting. This application allows you to pick and choose which LLM or Vector Database you want to use as well as supporting multi-user management and permissions. AnythingLLM is a full-stack application where you can use commercial off-the-shelf LLMs or popular open-source LLMs and vectorDB solutions to build a private ChatGPT with no compromises that you can run locally as well as host remotely and be able to chat intelligently with any documents you provide it. AnythingLLM divides your documents into objects called workspaces. A Workspace functions a lot like a thread, but with the addition of containerization of your documents. Workspaces can share documents, but they do not talk to each other so you can keep your context for each workspace clean.

    PenEcho

    PenEcho

    Think with AI beyond the chat box

    PenEcho is an open-source shared canvas that makes handwriting, equations, diagrams, and spatial context part of an AI conversation. Users can draw with pressure-sensitive ink, erase, pan, zoom, type formatted text, and arrange ideas across a large virtual workspace. The application sends focused visual regions to an API, Codex CLI, or Claude CLI and converts model responses into editable canvas commands. AI output can include text, formulas, plots, mixed drawings, erasures, and declarative animations. Sparse tile rendering keeps the 20,000-by-20,000 logical canvas efficient without allocating one enormous bitmap. Local snapshots, undo and redo, lasso selection, PNG export, and manual or automatic AI modes support iterative work. PenEcho is available as a desktop application or Node.js package and supports configurable models, reasoning levels, request retention, and plugins.

    Agent Skills

    Agent Skills

    Skills for AI coding agents

    Agent Skills by Vercel Labs is a curated collection of modular “skills” designed to extend the capabilities of AI coding agents by packaging human-ready instructions, workflows, and optional scripts that tell an agent how to perform specific development tasks. In this repository, each skill adheres to the Agent Skills specification, meaning they’re defined as folders with a SKILL.md file (containing task descriptions and step-by-step guidance) and can include helper scripts and reference material that the agent can execute or consult when invoked. The goal of the project is to make it easy for AI assistants like Claude Code, OpenCode, Cursor, Codex, and others that support this open ecosystem to automatically apply best practices or perform concrete actions when a relevant user intent is detected. For example, some skills guide the agent in applying React and Next.js performance best practices, auditing UI and accessibility standards.

    ego (lite)

    ego (lite)

    The fastest browser for AI agents to run web automation

    Ego Lite is a macOS browser designed for people and external AI agents to work in parallel. Each agent receives an isolated Space, allowing several browser tasks to run simultaneously without taking over the user's active tabs. Optional Chrome data migration carries over logins, cookies, extensions, and bookmarks so agents can use authenticated sessions with less setup. The ego-browser skill connects tools such as Codex, Claude Code, Cursor, and custom agent CLIs to the browser. Agents interact through JavaScript tools for navigation, snapshots, form entry, clicks, waiting, and captures. Browser data remains on the device, and users can observe, stop, or take control of an agent's Space. Windows and Linux versions are listed as future work rather than currently supported releases.

    Codex Dream Skin

    Codex Dream Skin

    Give the Codex desktop a breathing face

    Codex Dream Skin is an unofficial theming tool that changes the appearance of the Codex desktop application. It injects external styles through a local Chrome DevTools Protocol connection instead of modifying the official application package. Users can apply custom images and visual themes while retaining the native sidebar, project selector, suggestion cards, and input controls. The project provides platform-specific scripts for macOS and Windows. A restore process returns Codex to its original appearance with minimal effort. It binds its injection service to the local loopback interface and leaves API provider settings untouched. The repository also includes verification, recovery, and contribution guidance for safer customization.

    008

    008

    Open-source event-driven AI powered Softphone

    008 is an open-source event-driven AI powered WebRTC Softphone compatible with macOS, Windows, and Linux. It is also accessible on the web (though official support for browser-related issues is not provided). The name '008' or 'agent 008' reflects our ambition: beyond crafting the premier Open Source Softphone, we aim to introduce a programmable, event-driven AI agent. This agent utilizes embedded artificial intelligence models operating directly on the softphone, ensuring efficiency and reduced operational costs. This project is a WebRTC softphone, and communication is achieved via SIP over a socket. Leading PBX systems like Asterisk or Freeswitch support socket connections. If your provider does not offer this feature, consider using a SIP proxy such as Kamailio, Opensip or Routr. The softphone is internally configured using a JSON definition. The configuration file can be loaded from either a server or a local file. 008 reads the file only once.
