Plans & Pricing

Model

Mem 2.0 engine; 25 notes/month; 25 chat messages/month; basic AI organisation; semantic search (limited)

Usage Limits

25 notes/month; 25 Mem Chat messages/month; basic search; no unlimited collections; no templates; no API keys; no meeting briefs

Use Cases

Personal Productivity

9.0

Zero-folder AI organisation eliminates the time spent deciding where to file notes — a friction point that Notion and Evernote require users to manage manually; Heads Up surfaces related notes in real time while writing, reducing context-switching overhead.

Research

8.5

Deep Search finds notes by semantic intent — "that conversation about Q3 budget" — without requiring exact keyword recall; Mem Chat synthesises answers across multiple notes, enabling researchers to query accumulated knowledge conversationally rather than browsing files.

Content Creation

8.0

Smart Write generates drafts grounded in the user's own accumulated notes and writing style; Mem Chat creates new content from existing knowledge base context; output quality depends entirely on the volume and quality of notes previously captured in the system.

Automation

7.0

Zapier integration enables Mem output to flow to external tools including Notion, email, and project trackers; email forwarding to save@mem.ai auto-ingests external content into the knowledge base; native automation scope is limited compared to dedicated workflow platforms.

Education

7.5

Students can capture lecture notes, research snippets, and readings without manual organisation; Mem Chat synthesises connections across notes for essay and project preparation; free tier's 25-note monthly limit is insufficient for students with active coursework without upgrading to Pro.

Overview

Mem AI is a personal knowledge management platform rebuilt as Mem 2.0 in October 2025 and positioned as an AI Thought Partner rather than a traditional note-taking app. Its zero-folder model auto-categorizes and connects notes using AI without requiring manual tagging or folder organisation. Mem Chat operates agentically — it can create, edit, and organise notes through conversation, not just retrieve them. Deep Search understands semantic intent rather than matching keywords. Heads Up surfaces related notes in real time as users write. Mem differentiates from Notion and Obsidian by eliminating manual organisation entirely; AI handles all structuring. The free tier restricts users to 25 notes and 25 chat messages per month. No Android app exists — mobile access requires iOS only. Agentic Chat is grounded solely in the user's own notes and cannot access external knowledge.

Key Features

  • Agentic Mem Chat creating, editing, and organising notes through conversational AI grounded in the user's entire accumulated knowledge base
  • Deep Search finding notes by semantic intent and meaning rather than exact keyword matching across the full note library
  • Heads Up real-time context panel automatically surfacing related notes and collections as users write without requiring manual search
  • Zero-folder AI organisation auto-categorising and connecting notes without manual tagging, filing, or folder management
  • Email forwarding to save@mem.ai converting incoming emails into organised notes automatically linked to related existing content
  • Voice Mode capturing hands-free speech-to-text notes with original audio recording preserved for later playback

Pros & Cons

Pros

  • Agentic Mem Chat can create, edit, and reorganise notes through conversation — not just retrieve them — making it functionally more powerful than the AI assistants in Notion AI or Obsidian which primarily generate or summarise without modifying the knowledge base
  • Zero-folder organisation eliminates the cognitive overhead of deciding where to file information at the moment of capture, a persistent friction point in structured tools like Notion and Evernote that require upfront organisational decisions
  • Mem 2.0 includes full offline support across web, desktop, and iOS — a significant improvement from version 1.0 and a capability that cloud-first competitors like Notion lack in offline editing fidelity
  • Email integration via save@mem.ai consolidates scattered email threads directly into the knowledge base without manual copy-paste, reducing the number of context switches required to maintain a unified information store

Cons

  • No Android app — mobile access is iOS only, excluding Android users from native mobile note capture entirely; the web app is available on Android via browser but without native app experience or push notifications
  • Free tier restricts users to 25 notes and 25 chat messages per month — limits exhausted within days for active users, making the free plan insufficient for meaningful evaluation without upgrading
  • Agentic Chat is grounded exclusively in the user's captured notes and cannot access external knowledge — unlike ChatGPT, Mem cannot answer questions requiring information not already in the knowledge base
  • User reviews consistently cite poor customer support, buggy tag behaviour, missing text highlighting, and slow performance as unresolved issues in Mem 2.0 post-launch

Who It's For

Best For

  • Knowledge workers, consultants, and researchers who capture high volumes of notes across multiple contexts and need AI-driven retrieval without maintaining folder or tag systems
  • Freelancers and solopreneurs managing client knowledge, meeting notes, and project context across many relationships without a team wiki platform
  • Writers and content creators who want AI drafting assistance grounded in their own accumulated ideas and research rather than generic LLM output
  • Product managers and founders needing a searchable knowledge base that surfaces relevant past context before meetings and during project work

Not Ideal For

  • Android users — no native Android app exists; mobile access requires iOS or browser-only experience
  • Teams requiring project management, task tracking, databases, or collaborative wikis alongside note-taking — Notion or Linear are more appropriate
  • Users who prefer manual organisational control with custom folder hierarchies, explicit backlinks, and local file storage — Obsidian serves this use case
  • Anyone needing AI that can answer questions requiring external knowledge beyond their own notes — Mem Chat is limited to captured knowledge only

Audience Scores

Researchers8.8

Deep Search across unlimited notes on Pro (~$8.33/month annual) enables semantic querying of accumulated research without exact keyword recall; Heads Up surfaces related research notes automatically while drafting, reducing the time gap between capture and synthesis in literature-heavy workflows.

Freelancers8.5

Zero-folder organisation eliminates the overhead of maintaining client-specific folder systems; email forwarding auto-ingests client communications into the knowledge base; no Android app limits mobile capture for freelancers working outside iOS environments.

Product Managers8.2

Collections on Pro allow meeting notes, research, and project context to belong to multiple simultaneous groupings without duplication; agentic Mem Chat can draft PRDs and meeting summaries from accumulated knowledge; meeting briefs beta feature on Pro surfaces relevant notes before scheduled meetings.

Startups7.8

Pro plan at ~$8.33/month annual provides unlimited knowledge capture and AI organisation without per-seat complexity for solo founders; Teams plan requires contact sales and adds group billing and SLAs for early-stage teams needing shared knowledge bases; no native project management features limit Mem's scope for teams needing task tracking alongside notes.

Often Used With

Zapier

Primary automation integration enabling Mem output — daily digests, synthesised notes, chat responses — to flow automatically to Notion, Google Docs, Slack, or email.

Consider These Instead

When Not To Choose Mem AI

Choose Notion AI when team collaboration, structured databases, project wikis, and task management are needed alongside note-taking — Notion's AI features sit inside a more comprehensive workspace with stronger team and project management capabilities than Mem's note-focused architecture. Choose Obsidian when local-first storage, full offline capability, data ownership, Android support, and plugin-extensible customisation are priorities — Obsidian is free for personal use and provides granular control over note structure that Mem deliberately removes. Choose Capacities when object-based note-taking with explicit type classification (person, book, project, meeting) is preferred over Mem's freeform structure — Capacities provides a modern alternative with similar AI features and explicit semantic structure.
