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.

AudioBud is a dictation app for Windows that puts speech into the text field you're writing in. It builds on Handy by CJ Pais and suits people who want voice typing with local speech recognition rather than a hosted transcription service.

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.

Gensim is a free, open-source Python library for developers and researchers working with large text collections on their own machines or servers. It trains models that capture topics and semantic relationships, then uses those representations to find related documents. It runs on Linux, Windows and macOS under the GNU Lesser General Public License v2.1 (LGPL-2.1).

KoboldCpp runs language models on your own hardware for chat, creative writing and roleplay. It's a fork of llama.cpp with a bundled KoboldAI Lite browser interface.

Hillnote is a writing and planning workspace for people who want local files and AI help inside their editor. It keeps your work as plain Markdown on disk, readable by other editors and accessible to AI agents.

ExtractThinker is a Python library for developers who want to extract structured data from documents using models running locally through Ollama. It also supports OpenAI, Anthropic and Groq. With a cloud provider, extraction sends document content to that service, requires provider credentials and may incur charges.

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.

LivePortrait animates a portrait with facial expressions and head movements taken from a driving video. It's for creators who want to animate still faces or edit portrait videos on their own hardware.
