Duck.ai
Duck.ai is DuckDuckGo's free AI chat that gives anonymised access to a selection of popular models from major providers, with image creation and a deliberately light, privacy-first footprint. It is a privacy-focused front-end rather than its own frontier model.
- Genuine privacy-first approach
- Free access to capable models
- Simple and fast to use
- Try several models in one place
- A front-end, not its own frontier model
- No memory, files or long-context projects
- Limited integrations and advanced features
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
