|---|---|---|---|---|
| Tagline | AI search done right. Cited answers, not chat theater. | Anthropic's CLI agent. Opus-powered, operates on your repo directly. | An agentic iPhone home screen that replaces your static icon grid with AI widgets that proactively surface health, calendar, finance, and local context — without you having to open a single app. | AI slide decks that don't look AI-generated. |
| Category | Research | Coding | Agents | Productivity |
| Pricing | Free + $20/mo Pro | Part of Claude Pro/Max/Team plans | Waitlist / Beta (pricing not yet disclosed) | Free + $10-$20/mo |
| Best for | Replacing Google for any question where you want a cited answer in seconds. | Developers who want an agent, not autocomplete. Large refactors, tests, docs. | iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day. | Pitch decks, proposals, internal presentations — fast. |

| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | The concept is genuinely compelling — turning the home screen into a living AI layer is a smarter bet than yet another chat interface — but this is vaporware until it ships publicly and we see whether Apple's sandbox lets it breathe. (Verdict pending Phi's full review.) | A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes. |
