Tagline	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.	The fastest AI inference in the world. Crazy low latency.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	Google's research notebook. Turns your docs into a podcast.
Category	Agents	Dev Platform	Coding	Research
Pricing	Waitlist / Beta (pricing not yet disclosed)	Free tier + pay-as-you-go API	Part of Claude Pro/Max/Team plans	Free
Best for	iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.	Developers who need sub-100ms LLM responses.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Students, researchers, anyone with a stack of PDFs or a topic to learn.
Strengths	Ambient, proactive intelligence delivered via native iOS widgets — no app-switching required Cross-domain context: health, calendar, email, finances, and local recommendations in one layer Works within iOS permission model (no jailbreak or sideloading), making App Store approval plausible Strong pre-launch signal: 25k+ waitlist and backing from a16z, True Ventures, and SV Angel	500+ tokens/sec on Llama/Mixtral — feels instant Custom LPU hardware Great free tier	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Upload anything, ask questions, get cited answers Audio Overview turns docs into a 10-min podcast Great for studying
Weaknesses	Still pre-launch / beta — zero proven track record and no public pricing yet iPhone-only by design, which immediately locks out half the smartphone market Battery drain and privacy concerns from constant ambient context scanning are real and unresolved	Open-weight models only (no Claude/GPT) Less flexibility on custom configs	Terminal-based — learning curve Can't be used without Claude subscription	Google-only Can be slow on large corpora
Kai's verdict	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.)	S-tier for speed. When latency is the product, start here.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
