LLMII labels image collections with AI-generated captions and keywords for people who want searchable photos without uploading them to a cloud service. It processes folders on your computer and saves descriptions that other photo tools can read.

py-xiaozhi is a Python AI voice client for people who want to try Xiaozhi conversations on a computer or build voice interaction into hardware projects. It builds on the xiaozhi-esp32 project and lets you use a desktop microphone and speakers without dedicated Xiaozhi hardware.

OSWorld is a benchmark for researchers and developers testing AI agents that use computers. It measures task completion in real desktop environments, including workflows that cross application boundaries.

DeepAudit is an AI code security auditing platform for developers and security researchers who want to investigate vulnerabilities in their projects. It combines automated code review with executable tests to help assess whether suspected flaws are exploitable.

ON1 Resize AI is a paid desktop photo upscaler for photographers preparing large prints, enlarging tight crops or restoring old scans. It also handles AI-generated artwork and combines AI with Genuine Fractals enlargement technology.

Grok Build is a terminal coding assistant whose runtime edits files and executes commands on your computer. The default connection uses xAI’s remote inference service and needs network access and authentication. Browser login, device codes and API keys are supported, and organizations can configure third-party BYOK endpoints.

Murmure turns speech into text on your computer for people dictating notes, documents or code who want to keep recordings off cloud transcription services. It uses NVIDIA Parakeet and works offline without an account.

Lemonade is a local AI server for people who want to chat with models on their own hardware or use them in apps and agents. It includes a built-in interface for direct use and APIs for connecting other software.

FlyMD is a Markdown editor for people who keep notes, write long documents or publish blogs. It stores documents locally and adds writing assistance and document tools through extensions.

unbagrnd removes image backgrounds locally for people who need cutouts without uploading pictures to a cloud service. It includes an app for individual images and folders, plus a self-hosted API for developers.

Sokuji translates speech for people taking part in meetings across languages. Other participants hear your translated voice as ordinary call audio, so they don't need to install anything.

Terax brings a terminal, code editor and AI coding agents into one desktop workspace. It's for developers who want to work with agents alongside their shell, files and running app.

Agnai is an AI roleplay chat app for people who want conversations with fictional characters, including shared chats with other people. It builds on early work from Galatea-UI by PygmalionAI.

Zeraix is a local AI desktop for people who want models to work with their files and carry out multi-step tasks. It combines chat, project tools, and agents in one workspace.

Transcritório is a desktop app for researchers transcribing interviews and focus groups, with a focus on Brazilian Portuguese. It keeps audio, transcripts and metadata on your computer.

OpenResearch is an MIT-licensed, open-source workspace for people using AI coding agents to conduct research. It gives each research direction a separate agent session and isolated Git worktree, so experiments can proceed in parallel without sharing the same working files. Desktop builds support macOS and Linux; the Windows beta requires Git for Windows. A local browser dashboard is also available.

Voice-Clone-Studio brings voice cloning and speech production into one browser interface for people making podcasts, audiobooks and dialogue recordings. It combines several engines with tools for preparing samples and training custom voices.

SmartSub helps video creators subtitle recordings and dub them into other languages. You can use its transcription, translation, proofreading, dubbing and export tools separately or combine them for batch processing.

VideoProc Converter AI is a proprietary desktop app for Windows and macOS that combines local AI media enhancement with conversion and compression. It's for creators working with camera footage, people restoring old photos and videos, and anyone preparing large media files for playback or sharing. It processes files on your computer, and batch conversion works offline.

OpenHarness is a Python framework for developers and researchers building AI agents that can act on files, use tools and retain work across sessions. It includes ohmo, a personal agent that handles coding tasks through Feishu, Slack, Telegram or Discord.

Loop.js is an AI agent framework for developers who want repeated attempts at a task with a separate check of the result. You define the goal and completion criteria, and the engine coordinates work until the verifier accepts it or a stopping condition ends the run.

Qwen Code is an AI coding assistant for developers who want an agent to review code, fix bugs and carry out work in a project. You can use it in a terminal, editor, desktop app or browser.

Row-Bot is a local AI assistant for people who want to research, create documents and automate work on their own computer. It combines conversations with memory and agents that can continue working on longer tasks.

Miko is an AI companion for people who want to talk with an animated character on their Windows desktop. It pairs a local language model with a customizable 3D avatar and spoken replies.

OCRmyPDF makes scanned PDFs searchable and lets readers copy recognized text from them. It's a command-line tool for people digitizing paper records and developers adding OCR to document workflows.

Instrukt is a terminal app for developers who want to build and test AI agents on their own machine or server. It can index local code and documents, but its chat models run through OpenAI's API, which requires an API key and internet access. It doesn't provide local chat inference.

Project Orchestrator coordinates AI coding agents for developers working across tasks or related repositories. It gives agents a shared record of code, plans and decisions so each task can draw on earlier work.
