jo vs ChatGPT

ChatGPT handles open-ended questions, research, writing, coding, file analysis, deep research, apps that connect to other tools, and documents, decks, spreadsheets, sites, and analyses. ¹

jo uses context from your email, calendar, contacts, files, messages, browser activity, and active Mac windows when you enable them. It prepares research, plans, drafts, and browser-assisted work, then helps with reminders and follow-through.

ChatGPT Memory can use past chats, saved memories, custom instructions, Library files, and connected-app content where available. You can review, correct, or delete its remembered information. ²

jo maintains relevant context across conversations, projects, and connected sources. It can surface briefings and recurring autopilot results before you ask.

ChatGPT is available on web, iOS, and Android. Paid plans add desktop, web, and mobile access to ChatGPT Work, plus projects, scheduled tasks, custom GPTs, and more memory. ¹

jo works on Apple Silicon Mac and web, with the same account on mobile web, iMessage, WhatsApp, and Telegram. There is no native mobile app yet.

ChatGPT has Free, Go, Plus, and Pro plans; Plus is $20/month and Pro starts at $100/month. Personal-account content may be used to train models unless you opt out; business products are not used for training by default. ^{1 3}

jo gives every user an isolated cloud machine and storage, uses zero-retention model endpoints, and does not train on mail, messages, or screen content. jo asks for approval before it sends, books, buys, or changes a calendar. It is free while in beta, with no waitlist.
