Khoj
Khoj is an applied artificial intelligence company building in the open. It ships three products: Open Paper, a research workbench with verifiable citations; Pipali, a desktop AI co-worker running locally; and the Khoj app, a second brain with agents and automations across your documents and the web.
- Three genuinely different products rather than three modes of one
- Local execution resolves retention, training and jurisdiction questions outright
- A local agent can act in your real environment, which hosted assistants cannot
- Verifiable citations make Open Paper a research tool rather than a summariser
- A tiny team maintaining three products is a real continuity risk
- Open does not mean maintained, and small open projects go quiet
- Local execution consumes your hardware and is limited by it
