Audapolis is an editor for recordings where spoken words are the main material. Podcast producers, radio editors and people cutting interviews can work with a transcript through an interface similar to a word processor.

Shinkai lets people build AI agents to automate tasks without writing code. Its desktop app can run agents entirely offline with local models, including workflows that handle sensitive data.

LocalText2Voice is an MIT-licensed desktop app for people producing audiobooks, lessons and podcasts from long texts. Its local speech engines work offline after model downloads, keeping your text and generated audio on your computer. It runs on Windows and Linux; macOS isn't officially supported.

Lumina Note is a Markdown note-taking app for people who want AI help with writing and organizing a note collection. Its agent can work across the vault with your permission, while notes remain plain files you can edit and back up outside the app.

LiteRT-LM is Google's open-source framework for developers building apps that run language models on the user's device. It uses LiteRT for local inference across mobile devices, desktops and browsers, with GPU and NPU acceleration. The project uses the Apache 2.0 license.

biniou brings AI chat and media creation into one browser interface on your own computer or server. It's for people who want to work with several kinds of generative AI without switching between separate apps.

Letta is an AI agent platform whose App Server can run locally or on a self-hosted server. It's for people building assistants that retain context between conversations and use that memory in later interactions. Local agents can use Ollama or LM Studio with agent state and the model endpoint on your machine. Cloud model connections use remote providers.

LLPlayer is a media player for language learners who study through video and audio. It pairs playback with tools for reading dialogue, checking unfamiliar words and revisiting scenes.

Claude Command Center helps developers keep track of coding agents working across multiple projects. It finds sessions launched in a terminal as well as through the dashboard, and agents keep running when you close it.

Voicetypr is a desktop dictation app for people who write emails, code, prompts, or notes throughout the day. It inserts speech as text wherever your cursor sits, including in Slack, Gmail, Cursor, and Notion. Local transcription works offline, with your recordings and transcripts staying on your machine. The source code uses the AGPL-3.0 license; the desktop product is paid.

Next AI Draw.io turns written descriptions and uploaded files into diagrams you can edit on a draw.io canvas. It's for people creating technical diagrams who want AI help with drafting and revisions while keeping control of individual shapes.

MinerU is a local document parser for people preparing files for AI workflows. It handles scanned PDFs, academic papers and other documents containing OCR text, tables, figures or complex layouts.

Stability Matrix is a desktop app for people who want to use several Stable Diffusion interfaces with one model library. It manages local Web UI packages and includes its own interface for generating images.

Moonshine is an on-device AI toolkit for developers building voice agents and spoken interfaces. Voice processing runs on the device without an account or API keys.

Maat Agent is a coding assistant for developers who want testable evidence before accepting AI edits. It runs in a terminal or an Electron desktop app on macOS, Windows and Linux, and checks the actual project files against acceptance criteria set before work begins. Failed checks send their output back to the model for another attempt; if the work still fails, the agent reports failure.

Off Grid AI is a local AI app for people who want chat, document analysis and media tools on their own phone or computer. Downloaded models work offline, and the core app doesn't require an account.

GPTQModel is a Python toolkit for developers compressing LLMs and running them on their own hardware or servers. It combines model preparation, quality evaluation and inference so you can assess compression choices within one workflow.

Kohya's GUI is a browser interface for training image generation models, aimed at artists and model makers who want to teach a model a style or subject. It builds on Kohya's Stable Diffusion training scripts and also provides a command-line interface.

Skales is an AI agent for people who want help with files, browsing, email and coding on their own devices. It can keep working on a goal after you close the chat and resume unfinished goals after a restart.

Pi Web is a browser workspace for developers using the pi coding agent. It shares pi's local conversations and configuration, so you can resume the same coding work in either interface.

Agent Pilot is a desktop AI workflow builder for people who want to combine model conversations with tools and code. It runs on Windows, Linux and Intel Macs and is open source under AGPL-3.0. You can chat with one model or build a graph of cooperating agents, with human input included where a task needs it.

EasyOCR is a Python library for developers adding text recognition to an application. It reads both text in photographs and dense document text.

Devo is a coding agent for developers who want to choose their model provider and run the agent on their own machine. Its desktop app and terminal interface handle coding and other engineering tasks that require multiple steps.

iZotope Neutron is a proprietary audio mixing suite for producers, musicians and mix engineers who want an assisted starting point and control over individual effects. Its AI-powered Mix Assistant helps shape a mix, while manual controls let you build your own processing chain.

WindsurfAPI, also called DevinAPI, connects coding assistants and other AI clients to models through your own Devin account. The gateway runs on your hardware, but it sends prompts and images to Devin's cloud for inference, so it requires internet access.

GenOffice is a Microsoft Office alternative for people who want to edit documents on their own computer and let an AI agent make changes inside the files. It works with native .docx, .xlsx and .pptx files alongside PDF, Markdown and HTML.

nvitop is a terminal GPU monitor for people running AI workloads on NVIDIA hardware. It shows GPU activity alongside the processes using it, so you can check resource use and investigate busy devices.
