It runs errands on real websites in a cloud browser, such as bookings, forms and shopping, turns messages into tasks and projects, fills a CRM from your conversations, and runs routines like a morning brief or a price watch. Everything it does lands in a web workspace, its memory can be read, edited and exported, and it asks before paying, contacting someone new or deleting anything, with cards and passwords kept in an encrypted vault.

Personal AI that builds a private memory from your email, meetings, messages and screen and acts as your digital twin, drafting and answering in your voice.
Added
Sundae
Sundae is a personal AI assistant you text from iMessage or Android RCS, with no app or account needed. It works on a computer of its own: it books tables, finds flights at current prices, compares shops, reads letters and photos you send, sets reminders, watches prices and builds simple web pages, then texts back with a screenshot so you can check. It remembers what you tell it, asks before spending money, sending, deleting or opening accounts, and stops at checkout for you to pay. It is free to start with a daily limit, with a paid Plus plan, and is in limited beta.
Added
TecAdRise Bot
TecAdRise Bot is a free, MIT-licensed Windows desktop app (Electron and Cursor SDK) for running a local team of AI agents, each with its own model, memory, skills, MCP servers, workspace and schedule.
