Whelk: Private AI Platform

Your models. Your agents. Your network. Whelk is a private AI you run on your own hardware. Most AI apps ship your work to someone else's cloud. Whelk doesn't. Your models, your agents, and your data stay on machines you control — your laptop, your workstation, the server in the next room. The frontier-lab app experience, on infrastructure that never leaves your walls. ONE SURFACE FOR EVERYTHING - Chat — fast and native, a keystroke away from the menu bar - Notebooks — persistent AI workspaces that hold your context instead of a throwaway thread - Voice — talk to your AI, hands-free - Inline AI, systemwide — summon Whelk on any text in any app, without switching windows - Fork & branch — split any conversation to explore a different path, then come back - Composer — draft, edit, and refine long-form work with the model beside you - Agents — put your models to work on real tasks, across your own network PRIVATE BY ARCHITECTURE, NOT BY POLICY Whelk runs the AI where your data already lives. Nothing is sent to a third-party service unless you connect one yourself. No training on your conversations. No telemetry you didn't turn on. Close the lid and it goes with you. FREE FOR INDIVIDUALS Whelk is free for personal use, with no account required to get started. Teams add shared workspaces and simple per-seat licensing. Organizations add Whelk Enterprise: a self-hosted admin server with seat-based controls and the compliance posture larger teams require. Bring your own models. Keep your own data. Whelk is the private AI that answers to you.
