Mem is your personal AI agent—a chief of staff that builds a living picture of your tasks, projects, and goals, then helps you follow through. Capture notes, meetings, ideas, research, and links without stopping to organize. Mem Agent uses that context to answer questions, recall details, plan, draft, summarize, and move work forward. YOUR WORKSPACE, KEPT FOR YOU Write it down, say it out loud, record a meeting, or save it from another app. Mem keeps everything connected, searchable, and ready when you need it. ASK ANYTIME. SKIP THE BRIEFING. Mem Agent knows the context you have saved, so you can ask what matters now instead of rebuilding the backstory. Recall a detail, summarize a week of meetings, connect related ideas, draft a message, or plan the next step. PROACTIVE WORK THAT SCALES Mem automatically detects and tracks tasks and projects from the notes you create or edit. With Mem Pro, add custom routines that prepare briefings, do research, organize notes, and send scheduled reminders. Connect tools like Gmail, Slack, and Todoist so Mem can use more of your work as context. VOICE NOTES THAT STAY USEFUL Record a thought, meeting, or reminder. Mem keeps the audio and transcript together and helps turn rough input into clear, structured notes. FIND ANYTHING YOU’VE SAVED Search by topic, person, project, or a vague memory. Mem helps retrieve information even when you do not remember the exact wording. CAPTURE FROM ANYWHERE Use Share to Mem to save text, links, webpages, files, and more from other apps. Capture quickly, then return to the work in front of you. AVAILABLE ACROSS YOUR DEVICES Use Mem on iPhone, Mac, Windows, and the web. Work offline on iPhone, then sync when you are connected again. PRIVATE BY DEFAULT Your notes start private. Share them only when you choose. Every plan includes Mem Agent; usage limits vary by plan. Custom routines and connections require Mem Pro or higher. Trial eligibility and pricing are shown in the app. Privacy Policy: https://get.mem.ai/pages/privacy Terms of Service: https://get.mem.ai/pages/terms-of-service
