Tagline	AI search done right. Cited answers, not chat theater.	OpenAI's browser agent. Clicks and types on websites for you.	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.	Open-source VS Code agent. Reads + writes + runs.
Category	Research	Agents	Agents	Coding
Pricing	Free + $20/mo Pro	Included with ChatGPT Pro $200/mo	Waitlist / Beta (pricing not yet disclosed)	Free (open source) + your API costs
Best for	Replacing Google for any question where you want a cited answer in seconds.	Power users willing to pay $200/mo for a browser bot.	iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.	VS Code users who want agentic coding without changing IDEs.
Strengths	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Actually uses websites — fills forms, clicks, checks out Built into ChatGPT Good for repetitive web tasks	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	Free extension for VS Code Plan + Act modes Model-agnostic (Claude, GPT, local) Sees terminal output and iterates
Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	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	Can burn tokens fast if not watched Less polished than Cursor
Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	B-tier. Still early. Manus is more flexible for less money.	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 free agentic option in VS Code. Use with Claude for best results.
