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
Perplexity AI
Perplexity AI is an answer engine that runs live web searches and returns cited answers, with Deep Research for long agentic reports, Spaces for persistent projects, the Comet browser, and the Sonar API for developers.
- Citations make answers checkable in seconds rather than on trust
- Deep Research replaces hours of manual comparison work
- Spaces keep long-running research context instead of losing it per chat
- Genuinely useful free tier, not just a teaser
- Cites whatever ranks, so weak sources can look authoritative
- Summaries occasionally overstate what the linked page actually says
- Live search can amplify a recent error before corrections circulate
