Oleafly is a desktop editor for researchers writing papers, theses and other long documents in LaTeX, Typst or Markdown. It brings the manuscript, PDF preview and research tools into one workspace, with projects stored as ordinary files you own.

Agent of Empires is a self-hosted session manager for developers working with several AI coding agents in parallel. It lets you follow work across projects and branches without keeping every agent's terminal open.

GrapeRoot is a local MCP context tool for developers using AI coding assistants on projects that require repeated file exploration. It selects relevant code before each prompt reaches the assistant and remembers earlier work.

Segment Anything for Microscopy adapts Meta AI's Segment Anything to biomedical images, with models fine-tuned on microscopy data. It's for researchers who need to label cells or structures such as mitochondria in electron microscopy volumes. The software runs locally on Windows, macOS and Linux and is open source under the MIT license.

Subtitle Edit is an offline desktop application for people creating captions or revising subtitle files alongside video. Editing, format conversion and playback run on your computer. Optional translation and speech services send requests to external providers.

Home Assistant Assist lets you control your smart home through natural language. It's built into Home Assistant and can process voice entirely on your own hardware, keeping those voice commands local.

FastDeploy is a self-hosted inference toolkit for teams deploying language and vision-language models on Linux servers. Built on PaddlePaddle, it supports offline inference and online serving.

Scriberr transcribes recordings locally for people who want to review meetings and voice notes without uploading audio to a cloud service. It combines transcription with playback, annotations and optional questions about the recorded conversation.

Presenton is an AI presentation maker for teams turning reports and source documents into decks, and developers adding slide generation to their apps. It can reuse an existing PowerPoint design so generated presentations follow your own layouts.

LLM Wiki is a desktop AI knowledge base for people building a research library or personal reference collection. It creates lasting, linked pages from your documents and updates them as your sources change.

IndexTTS is a local text-to-speech system for people creating spoken audio and developers adding speech generation to applications. It can reproduce a voice from a single reference recording.

BrowserWing is a local browser automation tool for developers and AI agent users who need repeatable website tasks and structured data. It lets you record a workflow once and make it available to agents as a reusable action.

LobsterAI is a desktop AI agent built on OpenClaw for office work and local projects. It operates tools on your computer and keeps sessions, configuration and memory there. You select each agent’s model separately from its workspace and tools.

SearchBox searches inside documents for people who remember a topic or phrase but can't find the file it came from. It keeps existing folders in place and makes their contents searchable.

Harbor helps people experiment with local LLMs by connecting model backends, chat interfaces and supporting services. Its CLI and companion app manage those connections in a shared development environment.

Best Claude HUD keeps session and repository information visible for developers working in Claude Code's terminal interface. It helps you check the active model, available context and working tree without leaving the conversation.

LocalVocal turns speech into live captions inside OBS for streamers and people recording video. It processes speech on your computer, so transcription can work offline without sending audio to a cloud service.

Hyperopt is a Python library for developers and researchers who need to tune model hyperparameters across complex search spaces. It can handle continuous values, discrete choices and conditional parameters, such as settings that apply only when a particular model or approach is selected. It runs within your Python project, with support for both serial and parallel optimization.

Contrabass coordinates AI coding agents working through project issues, for developers managing several tasks or agent teams. It runs locally on macOS and Linux and reimplements OpenAI's Symphony approach.

Albert coordinates Claude Code agents for developers who want to hand off a coding goal that spans several tasks. It plans the work and continues through successive rounds until it reaches the goal or a requested review checkpoint.

ZettaBrain RAG is a self-hosted document assistant for individuals and small teams working with policies, contracts and internal manuals. It helps them find answers and draft documents from files they already keep on their own infrastructure.

Real-CUGAN NCNN Vulkan is a command-line AI image upscaler for people enlarging anime artwork on their own computer. It uses Real-CUGAN models through the ncnn runtime to increase image resolution and reduce noise.

Nanocoder is a terminal AI coding assistant for developers who want to choose which model works on their code. It can use local models through Ollama or send requests to a hosted provider through an OpenAI-compatible API.

Agency Orchestrator coordinates specialist AI roles for developers and solo builders working on product plans, research or content. A task description can become a team that divides the work and combines its results.

Ultimate Vocal Remover separates vocals and other parts of songs on your computer. It's for people preparing karaoke tracks or isolating audio for music projects.

Claude Code Agent Monitor gives developers one place to follow coding agents and inspect their work across Claude Code, Cursor and Codex. It keeps conversations and activity available for review after a session ends.

OpenVINO Model Server is a self-hosted inference server for developers and teams serving AI models on their own machines or servers. It uses OpenVINO to run workloads on x86 CPUs, including Xeon, with acceleration for Intel integrated and discrete GPUs and NPUs. It's open source under Apache 2.0.

FastChat is a self-hosted LLM platform for developers and researchers who want to serve chat models on their own hardware and compare their responses. It powers Chatbot Arena and includes a locally hosted side-by-side comparison interface. The Python code is open source under Apache 2.0; model licenses apply separately, including Llama's license for Vicuna.

SwarmUI is a self-hosted AI image generation interface for people who want both straightforward generation controls and access to detailed ComfyUI workflows. You can use it with models running on your own hardware.
