Local AI Apps and Tools for Windows

VideoHighlighter is a desktop app for finding useful moments in long recordings without uploading footage for analysis. It helps creators cut highlights, reviewers inspect camera recordings, and interview editors locate material worth keeping.

Volyx Lens is an open-source desktop AI assistant for macOS, Windows and Linux that lets you choose which screen, microphone and system-audio inputs reach your AI provider. Linux support is experimental, with meeting audio captured on a best-effort basis. It's for people who want help with visible code, documents or meetings without continually copying context into a chat. A movable floating rail expands into chat and collapses when you don't need it.

GameStringer translates games for players and fan translators who want a language the game doesn't include. It detects the engine, extracts text and applies translated text to the game, with compatibility depending on the engine and title.

NotebookLlama is a self-hosted NotebookLM alternative for people who want control over the application code while using cloud services to process documents. It relies on LlamaCloud for document extraction and indexing, so self-hosting doesn't make the workflow fully local.

WhisperX is a local speech-to-text tool for transcribing interviews, meetings and long recordings. It builds on OpenAI's Whisper, adding individual word timings and optional speaker identification for subtitles and transcript review.

JoyCaption generates image descriptions for people preparing datasets to train or fine-tune diffusion models. It can caption images on your own GPU, reducing the work of writing training descriptions by hand.

NoteGen is an AI note-taking app for collecting research, meeting material and ideas before organizing them into finished documents. Notes remain ordinary Markdown files, with attachments stored on your device by default.

Kiln is a desktop workbench for teams building and testing AI applications. Engineers, QA staff and subject matter experts can work with the same tasks and datasets, including contributing ratings and examples without writing code.

ebook2audiobook converts non-DRM ebooks into narrated audio with chapters and metadata. It's for readers who want audio editions of legally acquired books, with a choice of speech engines and narrator voices.

sonible smart:EQ is a proprietary AI equalizer plug-in for producers and audio engineers who want to correct tonal imbalances while accounting for the rest of a mix. It runs in a desktop DAW on macOS or Windows, with native Apple Silicon support. Its cross-channel processing helps reduce frequency masking between tracks, so competing parts have more room in the mix.

OpenShell is a self-hosted runtime for teams that need autonomous AI agents to work with files and APIs under explicit access limits. It runs agents in isolated sandboxes and enforces policies at the kernel level.

PageLM is a self-hosted AI study platform inspired by NotebookLM. Students, educators and researchers can use it to turn their materials into resources for revision and exam practice.

FluxGym is a browser interface for training FLUX LoRAs on your own images. It's for people who want to customize image models locally, with support for GPUs with 12GB, 16GB or 20GB of VRAM.

LocaLM runs AI models on your own hardware for chat and optional tasks such as coding, document questions and media generation. It's for people who want a single local tool and can choose which extra capabilities to add.

Umi-OCR extracts text from screenshots and local images for people who need to copy on-screen text or process image collections without an online OCR service.

Emdash is a desktop development environment for developers who want to delegate several coding tasks at once. It keeps each task's branch, terminal, conversation, and review state together so parallel work stays separate.

sonible smart:reverb is a proprietary AI reverb plug-in for producers and audio engineers working on macOS or Windows. It analyzes a track's frequency content and timing to shape a reverb response around the source. Multiple instances can also work together across a mix to manage overlapping frequencies and control how near or far each sound feels.

Whisper Local is a free, MIT-licensed dictation app for Windows and macOS, aimed at people who want voice typing without cloud processing. It's an alternative to Wispr Flow and Dragon that inserts speech into the active text field, including in chat apps, browsers and code editors. It doesn't require an account or API key.

RealtimeSTT is a Python library for developers building voice assistants, dictation tools and apps that turn live audio into text. It can show text while someone speaks and produce a final transcript when they finish.

GPT Pilot is a local AI coding agent for developers who want to build applications under human supervision. The project is no longer maintained, and its model calls rely on external providers.

mcp-proxy connects AI clients and Model Context Protocol (MCP) servers that use different connection types. It's for developers who need desktop clients to reach remote tools, or want other clients to access a local MCP server.

Fed-BioMed lets hospitals and researchers train AI models across institutions while patient data stays on each institution's own infrastructure. It's a self-hosted platform for biomedical research that needs access to data across multiple sites but faces restrictions on sharing clinical records.

MEX keeps project knowledge alongside code so engineers and their AI coding agents can share context across teammates and sessions. Architecture, requirements and decisions live in readable Markdown that travels with the repository through Git.

LeanCTX helps developers control the information their AI coding tools receive. It runs locally between those tools and project files or command output, while your existing application keeps control of the model and workflow.

Open-LLM-VTuber is an AI companion for people who want to talk with a customizable animated character. Local language and speech models let it work fully offline, with conversations staying on your device.

AppFlowy is a workspace for documents, projects and AI. Its desktop Local AI plugin connects to Ollama for local model use. AppFlowy also offers a self-hosted server deployment with language and embedding models inside your environment, including air-gapped operation. The desktop plugin and server deployment are distinct ways to use AI.

PyTorch Forecasting is a Python library for developers and researchers who want to predict time series with neural networks on their own hardware. It combines ready-made forecasting architectures with data preparation, training, and evaluation tools. It's open source under the MIT license.

LoopX is an open-source control plane for AI agents working on multi-day coding, research and personal projects. It preserves the goal and decisions between sessions so work can resume after a pause or handoff.

SymForge is a local MCP server for developers using AI coding agents on large repositories or long source files. It gives agents focused views of symbols and their relationships so they can investigate code without reading entire files.

X-AnyLabeling is a desktop annotation workspace for researchers and teams preparing text, image, video, point cloud, and multimodal training datasets. Models generate initial labels, and reviewers correct them in the same workspace before exporting the data. It runs on Windows, Linux, and macOS under the GPL-3.0 open-source license.

ncnn is a C++ inference framework for developers adding on-device AI to mobile, desktop and embedded applications. It focuses on a small memory footprint and doesn't require third-party runtime dependencies.

TTS WebUI is a self-hosted browser interface for people creating speech and music or processing audio with AI models. It brings these tasks into one place, with model choices for different kinds of audio work.

Facet combines photo culling with a self-hosted gallery for photographers choosing keepers from a shoot or organizing a personal library. Its AI analysis runs on your own machine without cloud services, accounts or API keys.

llama-swap is a local AI proxy for people who want several models available to their apps without keeping them all loaded. It starts the server a request needs and replaces the active server when another model is requested.
