JesType is a paid dictation app for people who want to write emails, documents, and other text by speaking while keeping their audio on their own computer. It runs on Apple Silicon Macs with macOS 13.4 or later and 64-bit Windows PCs running Windows 10 or later. Intel Macs aren't supported.

SpeakUp is a dictation app for people who want to write by voice on a Mac. It's suited to confidential notes, everyday writing and reducing typing because of RSI or accessibility needs.

Mirrai is an AI companion for people who want to revisit unfinished conversations through a persona based on someone's chat history. It simulates their communication style, with a farewell process that gives the experience an optional endpoint.

InvokeAI is a free, open-source image generation application for artists who want to create and edit artwork on their own hardware. Its locally hosted browser interface combines direct canvas work with repeatable generation workflows.

Xinference serves AI models on your own computer or servers for developers and researchers building applications around models they control. It brings chat, document search and media generation into one platform.

StarDist detects individual cells and nuclei in crowded 2D microscopy images and 3D volumes. It's for researchers and bioimage analysts who need separate outlines for closely packed objects. Its shape-based approach suits objects that can be represented by star-convex polygons in 2D or polyhedra in 3D.

smart:limit is a proprietary AI audio limiter plug-in for mixing and mastering on macOS and Windows. It analyzes a track and suggests limiting settings, with loudness and dynamics meters in the same interface. It's aimed at producers and engineers preparing audio for release who want help controlling peaks while retaining detail in the mix.

Voice Changer (w-okada), also called VC Client, converts speech as you talk using AI voice conversion models. It suits people who want live voice changes, including gaming commentators running other demanding applications.

Whisperstream turns speech into text in the app you're writing in. It's for people who want to dictate messages, documents or coding prompts while keeping speech recognition on their computer.

Transcribe Offline turns recordings and live speech into text for people who need to review conversations without uploading audio to a cloud service. It pairs transcript editing with audio playback in a desktop app.

Moondream is a vision language model for developers building apps that interpret images, such as warehouse or manufacturing footage. Its downloadable models can run on your own hardware, including offline in an air-gapped environment.

noScribe transcribes recorded interviews for qualitative researchers and journalists who need to keep audio on their own computer. It processes recordings locally rather than sending them to a cloud transcription service.

Audiblez converts EPUB e-books into spoken audio using Kokoro-82M on your computer. It's for readers who want an audiobook version of a book, with control over the voice and which sections get read aloud.

Sidekick is a native macOS app for people who want AI answers grounded in their documents and research materials. Its built-in llama.cpp engine runs GGUF models such as Qwen3.5 without a separate model runner.

OwnPilot is a self-hosted AI assistant for people who want personal records and agents that can carry out tasks in one web interface. It supports local model backends as well as cloud providers.

whisper.cpp runs OpenAI's Whisper speech recognition models on your own hardware. It's for developers adding transcription to applications and people who need offline speech-to-text.

Libre WebUI is a self-hosted AI workspace for individuals and teams who want chat, document research and AI agent tasks on infrastructure they control. You can use local models or connect a remote provider of your choice.

NullHub is a self-hosted management console for people running NullClaw and its supporting tools. It brings agent instances, workflow runs and task queues into one browser dashboard.

LLM Farm is an app for on-device AI conversations and comparing language models on Apple hardware. It suits people who want offline chat or need to assess which model fits a project.

ZeroClaw is a personal AI agent for people who want an assistant running on their own computer or server. It can use a shell and browser, respond through messaging apps and perform scheduled tasks.

Open Generative AI is an AI image and video studio for creators who want to generate media on their own hardware. Local inference is available only in the desktop app.

FastSurfer processes structural human brain MRI scans on your own workstation or server, producing brain segmentations and cortical measurements compatible with FreeSurfer. It's for neuroimaging researchers working with individual scans or large cohorts who want shorter processing times within existing analysis workflows. The software is open source under Apache 2.0.

LM Studio runs downloaded language models for conversations and tasks on your computer. Its Bionic agent helps people create documents, write software and carry out work using local or frontier open models.

Agent S is a computer-use AI agent framework for developers and researchers building desktop automation. It takes natural-language tasks and operates desktop and web applications through their screen interfaces, without requiring an API integration for each app.
