What Mem does
Mem is an AI-first notes workspace that captures personal knowledge, finds it through semantic search, and uses workspace context to answer, edit, organize, and draft.
Mem approaches note-taking as a recall problem rather than a filing exercise. Notes can be captured on Mac, Windows, web, or iOS, clipped from a browser, shared from an iPhone, or sent by email, then synchronized across devices. Collections provide overlapping structure instead of forcing every idea into one folder. Search begins with title suggestions and keyword filtering, while Deep Search attempts to match the meaning of a query to note content. Heads Up can surface related material during work, and PDF and image understanding makes slide text, tables, handwriting, and visual content available to search and Chat.
The distinctive layer is Mem Chat. It can search the entire workspace or be constrained to attached notes and collections, then recall details, synthesize themes, create a new note, edit the open note, or apply organization. This makes Mem useful for preparing from previous meetings, turning scattered observations into a project outline, or recovering a fact without remembering its exact wording. The quality of that experience still depends on source quality. Duplicate notes, stale decisions, vague titles, and uncorrected transcripts can produce a confident synthesis of the wrong material, so important answers should be traced back to their notes.
Mem is best for an individual or small group that wants low-friction capture and contextual recall, not a highly relational project database or a formal records system. It currently supports English across its full feature set, requires Google sign-in, and has no Android app. The free tier is suitable for evaluation but limited to 25 notes, 25 chat messages, and 25 understood PDF pages each month. Pro is displayed at $12 monthly with annual billing or $14.99 month to month; Teams is custom-priced. Mem says it does not use notes or personal data to train generalized models and encrypts content in transit and at rest, but users should still review sharing, email connections, API keys, MCP access, and subprocessors before storing sensitive knowledge.
How Mem works
Mem indexes notes, imported content, PDFs, images, and permitted connected sources so keyword and semantic retrieval can surface relevant context. Chat uses the whole workspace or selected notes and collections to answer, create, edit, and organize, while the user verifies the result and controls sharing.
Accumulate useful source material
Create notes directly or capture permitted text, links, email, PDFs, images, and voice content through a supported client. Templates add repeatable structure, while offline work synchronizes when connectivity returns; source quality determines what retrieval can later recover.
Build a flexible knowledge layer
Mem indexes titles, note content, document pages, and understood visual material for keyword and semantic retrieval. Collections can overlap, and Auto-Organize proposes membership without forcing every note into one permanent folder.
Search or converse with context
Search moves from title suggestions to filtered results and Deep Search. Chat can use the full workspace or attached notes and collections to recall, synthesize, create, edit, or organize material, using multiple model providers selected by Mem.
Trace answers back to notes
Open the source notes behind important details, distinguish an old decision from the current one, and correct weak transcripts or duplicate content. Keep sharing, email capture, API keys, and MCP connections narrower than the knowledge base itself.
How to set up Mem
Create the workspace on a supported platform
Sign in with a Google account on web, Mac, Windows, or iOS; confirm that the lack of Android and official non-English support will not break the intended workflow.
Import a small, representative knowledge set
Add current notes, one PDF, and a few web or email captures rather than migrating everything immediately; remove secrets, obsolete decisions, and duplicate source material.
Establish lightweight organization
Create a few durable collections for projects or responsibilities, configure reusable templates, and let Auto-Organize propose placements that a person reviews.
Test retrieval and Chat separately
Run exact keyword searches, ambiguous Deep Search queries, and collection-scoped Chat prompts; open the source notes behind every consequential answer and correct weak content.
Set access and maintenance rules
Keep notes private by default, share collections intentionally, restrict API, email, and MCP connections, and schedule a recurring cleanup of stale sources and unused integrations.
Mem FAQs
Is Mem free?
Yes. The current free tier allows 25 notes, 25 chat messages, and 25 PDF pages understood per month. It is best treated as an evaluation tier rather than an unlimited notebook.
How much does Mem Pro cost?
As checked July 15, 2026, Mem displays Pro at $12 per month with annual billing or $14.99 with monthly billing. Teams uses custom pricing.
Which platforms does Mem support?
Mem documents Mac, Windows, web, and iOS apps with offline support and synchronization. It does not currently offer Android and officially supports English across all features.
Does Mem use my notes to train AI models?
Mem's March 2026 privacy notice says it does not use personal information, notes, or information collected through third-party services to develop, improve, or train generalized AI or machine-learning models.
Can Mem replace a project-management system?
Usually not. It excels at capture, semantic retrieval, synthesis, and flexible collections, but teams needing dependencies, capacity planning, formal approval states, or structured reporting should pair it with a dedicated work-management tool.
