Companion is a personalized AI assistant with the tagline “AI that knows you.” It is not just a chatbot: each Companion comes with a private computer that includes a browser, terminal, and file system. The goal is to help users research information, handle email, perform web-based tasks, organize information, and even generate small personalized apps—much like a real human assistant.
Based on the information on the site, Companion’s key capabilities include long-term memory, background execution, web browsing, form filling, data extraction, file handling, and deep research. It remembers user preferences, daily routines, important people, and topics of interest, and continuously improves in later conversations. In the examples shown, it can sort emails, draft replies, update an MRR Tracker, analyze reasons for customer churn, and even write a Safari bug-fix patch and push a branch. The page also says it can build trackers, journals, or small tools from a description and publish them online.
The current page indicates that users need to join a waitlist, and no free plan or free trial is shown. The paid plans are Plus at $20/month, Pro at $100/month, and Max at $200/month. The three tiers include 2,000, 10,000, and 20,000 monthly credits respectively, context windows ranging from 100k to 200k, file upload limits from 25MB to 500MB, and varying amounts of Companion email history. Annual billing saves 20%, and additional credits can be purchased.
The main advantage is that Companion offers a fairly complete product concept, combining a browser, terminal, file system, and long-term memory. This makes it suitable for complex tasks that span multiple websites, files, and time periods. Its pricing structure is also relatively clear. The limitations are that the page does not disclose the underlying model, API capabilities, third-party integrations, or detailed data privacy practices. Its ability to “remember everything” is appealing, but it also raises higher requirements for privacy, security, and permission management. Based on the captured content, it is not possible to judge how strong these safeguards are.
Companion is better suited to founders, indie developers, researchers, marketers, and heavy information workers. Potential use cases include operations weekly reports, investor updates, customer analysis, email handling, travel planning, and web research. If you only need basic Q&A, it may offer worse value than general-purpose chat tools. But if you need a personal AI workspace that can continuously take tasks off your plate, its positioning is more distinctive.
The captured text does not provide information on access from mainland China, supported payment methods, or Chinese-language support, so its availability should be considered unknown. If it cannot be used reliably, alternatives include ChatGPT, Claude, Gemini, Perplexity, Manus, Genspark, and Flowith.
