	Devin A	ChatGPT Operator B	Skye A	Lex A
Tagline	Cognition Labs' autonomous coding engineer.	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.	Google Docs with an AI collaborator baked in.
Category	Agents	Agents	Agents	Writing
Pricing	$500/mo	Included with ChatGPT Pro $200/mo	Waitlist / Beta (pricing not yet disclosed)	Free + $12/mo
Best for	Engineering teams offloading tickets. Ops/platform work.	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.	Essays, long-form drafts, thinking on the page.
Strengths	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did	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	Clean writing UX — distraction-free +++ prompt triggers AI help Collaboration + AI feedback together
Weaknesses	Expensive Best for well-scoped tasks Not for solo hobbyists	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	Less feature-rich than Google Docs AI ceiling below dedicated tools
Kai's verdict	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	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. Beautiful UX. The writing app I'd pick if I only wrote long-form.
