Mem is an AI note-taking and personal knowledge workspace from Mem Labs, Inc. It is built for people whose ideas, meetings, and reference material quickly spread across several apps. Mem brings typed notes, voice, meeting recordings, and web pages into one Workspace, then helps retrieve connections and draft from saved context. It is not a set-and-forget archive: transcripts, summaries, and Chat answers still need human review.
From a voice note to a working knowledge base
Voice Mode records, transcribes, and structures speech. The web version captures the microphone only, while the macOS and Windows apps can also capture system audio, which matters for online meetings. A Chrome extension clips web pages; email capture, an iOS app, an API, and Zapier cover other input routes. Uploaded PDFs and images are indexed, making their contents searchable and available inside Chat.
Mem runs on the web, macOS, Windows, and iOS, with offline use and synchronization. There is no Android app and no announced release date. Sign-in requires Google or Google Workspace. Only English is officially supported across the full feature set; other languages may work in part, but users should not assume equal transcription and retrieval quality.
Collections and Heads Up instead of perfect folders
Collections gather notes around a topic or project, while automatic rules reduce manual filing. Heads Up surfaces context that may be relevant beside the current note. This approach fits people who prefer semantic retrieval over maintaining a pristine folder tree. For alternatives, see AIDive’s collection of AI notes and personal knowledge tools.
Chat, Deep Search, and PDF context
Deep Search works across notes, recognized image content, and uploaded PDFs. Chat uses retrieved passages to compare, summarize, draft, and update existing notes. Meeting Briefings turn captured meetings into quick reviews. These tools make information reusable, but an answer can omit a caveat or join unrelated sources, so important conclusions should be checked against the original material.
Free, Pro, and Proactive serve different jobs
Free is limited to 25 notes, 25 Chat messages, and Search or Chat across 25 PDF pages per month. Mem Pro costs $12 per month and adds unlimited notes, Collections, templates, Chat, Deep Search with PDF support, email and API access, Meeting Briefings, model selection, and dark mode. Mem Proactive costs $99 per month after a 7-day trial and adds Mem Agent for proactive tracking, briefings, and reminders. For a conventional knowledge base, the jump from $12 to $99 only makes sense if the agent replaces recurring manual work.
Import, portability, and privacy
Imports accept Markdown and TXT, at roughly 1,000 files per batch. Folder structures and attachments are not preserved, and Word or Google Docs cannot be imported directly. The company says data is encrypted with AES-256 at rest and TLS in transit, but Mem is not end-to-end encrypted. Before moving a working knowledge base, test export, formatting, and attachment behavior on a small sample, and compare sensitive material with the organization’s data policy.
