About 1Presence

A personal AI assistant with lasting memory. 1Presence manages your email and calendar, connects the apps you use, and keeps what it learns as files you own. 1Presence builds a semantic memory across every conversation, projects, preferences, context, decisions. Liability is capped at the fees paid in the preceding twelve months. 1Presence reaches across the tools you already use, email, calendar, files, and fifteen-plus services, from Gmail and Google Calendar to Notion, GitHub, Slack and Microsoft 365, reading context and acting with your approval.

About CodeTrain

CodeTrain is a Socratic AI coding tutor: it asks questions, reviews what you write, and runs your tests, but never writes the code for you. Free to start. Two steps, about a minute, and the first one is going to catch you. The tutor's replies are pre-recorded, so it knows the handful of ways this lesson usually goes wrong. The real one reads whatever you actually wrote, and it is free for ten lessons a month.
