| Description | Jan is an open-source desktop app for Mac, Windows, and Linux that runs large language models locally so all conversations stay on your own machine. It's aimed at developers, privacy-conscious knowledge workers, and small teams who want a ChatGPT-style assistant without sending data to the cloud, while still allowing optional connections to hosted models like GPT, Claude, and Gemini via API keys. Its main differentiator is offline-first, on-device execution combined with the flexibility to switch between local open models and cloud providers in one interface. | Dia is an AI-native browser from The Browser Company (creators of Arc) that integrates with tools like Slack, Notion, Calendar, Gmail, and GitHub. It generates morning briefs, pulls together information spread across tabs and apps, answers context-aware questions about on-screen content, and helps users prepare for meetings. Aimed at knowledge workers, it is currently available only on macOS. |
