Personal knowledge management for smarter productivity
Mem is a personal knowledge and workspace app that uses AI to automatically capture, organize, and surface your notes and memories for knowledge workers. It suits individuals and small teams who want context-aware recall, bi-directional linking, and AI-assisted summaries. Pricing includes a usable free tier and paid plans for advanced AI and team features, making it approachable for solo users and scalable for teams.
Mem is an AI-powered personal knowledge management app that captures notes, tasks, and documents and surfaces them automatically for fast recall. It combines a searchable, backlinkable database with generative AI features—auto-summarization, suggested tags, and contextual recall—to reduce manual organization. Mem’s differentiator is its passive capture and smart surfacing: it learns from usage and suggests relevant memories without heavy tagging. It targets knowledge workers, product managers, and solo founders needing quick recall and low-friction note capture. A free tier exists, with paid plans to unlock advanced AI and team collaboration features.
Mem is an AI-first personal knowledge and productivity app that launched in 2020 and positions itself between a notes app and a lightweight personal wiki. Its core value proposition is passive capture and context-aware retrieval: Mem ingests notes, emails, and files and uses metadata, timestamps, and natural-language signals to surface relevant items when you search or work. The product aims to replace manual folder/tag labor by learning patterns in your content and proposing related items proactively. The company emphasizes “memory” as a continuously growing knowledge layer rather than isolated documents.
Key features focus on capture, search, summarization, and integrations. Smart Capture saves text, images, and files via native iOS/Android apps, the macOS app, web app, and a browser extension; Mem also supports email import and Web Clipper. Universal Search is a core capability: full-text search with contextual ranking that surfaces related notes, contacts, and tasks. AI Summaries automatically generate condensed summaries of notes and meetings; Mem can create TL;DRs and key-point lists from longer entries. Backlinks and templates let users create structured knowledge—bi-directional links help build connections across notes. The app offers Task management with reminders and simple kanban/board-like views, while integrations with Slack, Google Calendar, and Notion (via import/export) let Mem slot into existing workflows.
Pricing mixes a free tier and paid subscriptions. The free plan provides unlimited notes, basic search, and mobile/desktop sync but limits advanced AI features and team capabilities. Paid plans start at a Personal Pro tier (monthly or discounted annually) that unlocks advanced AI tools like longer AI summaries, priority search indexing, and extended version history. Team/Business tiers add SSO, shared spaces, admin controls, and workspace-level search and billing. Mem also offers enterprise/custom pricing for larger organizations needing audit logs and SCIM. Exact prices and limits change frequently, so check mem.ai/pricing for current numeric rates and annual discounts.
Typical users include knowledge workers who need low-friction capture and recall. Product managers use Mem to store meeting notes and automatically surface customer quotes during planning, while founders use it to keep investor communications and decision logs searchable and summarized. Other real workflows include researchers consolidating source notes and sales reps syncing meeting notes with Google Calendar. Compared to Notion, Mem focuses more on automatic organization and recall rather than manual page structure, making it preferable when contextual search and AI summaries matter more than heavy document layout.

Copy these into Mem as-is. Each targets a different high-value workflow.
Role: You are an AI assistant that writes concise, investor-friendly summaries. Input: a single meeting note pasted after this prompt. Task: produce a 4-line executive summary. Constraints: 1) Keep total length between 60–100 words; 2) Use plain language, no internal acronyms without explanation; 3) Do not invent facts. Output format: numbered lines: 1) Headline — one sentence capturing meeting purpose; 2) Summary — two short sentences of key outcomes; 3) Key metrics — comma-separated metric:value pairs mentioned; 4) Next steps — 2 clear owner+action items. Example input: “Discussed runway to Q3, closed $100k MRR, follow-up with legal.”
Role: You are an AI assistant that converts notes into prioritized tasks. Input: one note or meeting transcript provided after this prompt. Task: extract all implied and explicit action items. Constraints: 1) Output only tasks with a suggested owner and due date inferred from context (or mark TBD if none); 2) Prioritize tasks as High/Medium/Low based on impact and urgency; 3) Limit to 12 tasks. Output format: JSON array of objects: {"task":"...","owner":"...","due":"YYYY-MM-DD or TBD","priority":"High|Medium|Low","source_quote":"short excerpt"}. Example source: “We should follow up with design by next Monday.”
Role: You are an AI product analyst consolidating customer feedback. Input: multiple Mem notes of customer comments (paste or link list). Task: cluster feedback into top 5 themes and rank them by frequency and business impact. Constraints: 1) Provide theme name, one-paragraph synthesis, number of mentions, and estimated impact (High/Med/Low); 2) Recommend 2 concrete product experiments per High-impact theme; 3) Keep each synthesis ≤60 words. Output format: a numbered list of 5 theme blocks: {Theme, Mentions, Impact, Synthesis, Experiments}. Example: Theme=Onboarding friction; Mentions=12; Impact=High; Experiments=[A/B checklist, guided tour].
Role: You are an AI research assistant preparing an annotated bibliography for a literature review. Input: links or pasted excerpts from 5–10 source notes. Task: produce a table summarizing each source. Constraints: 1) For each source include these columns: Title, Authors & Year, Methods, Key Findings (2–3 bullets), Relevance to research question; 2) Keep Methods to one sentence, Key Findings bullets each ≤20 words; 3) Preserve citations exactly as provided. Output format: CSV with header: Title,AuthorsYear,Methods,KeyFindings,Relevance. Example row: “Paper A, Smith 2020,"RCT of 200 users","• Improved X by 20%","Directly tests hypothesis A"”
Role: You are a senior Product Manager creating a 3-month roadmap for a B2B SaaS startup. Inputs: a backlog exported from Mem, key company goals (ARR growth, retention), and team capacity (engineering 6 FTE, PM 1, design 1). Task: produce a month-by-month roadmap with priorities. Constraints: 1) Include initiative name, goal metric, estimated effort (T-shirt: S/M/L), required roles, and success criteria; 2) Prioritize initiatives by impact vs effort and mark dependencies; 3) Keep roadmap concise to 6–8 initiatives. Output format: JSON with months as keys and arrays of initiative objects. Provide brief rationale (1–2 sentences) per initiative. Example: {"April":[{"initiative":"Improve onboarding","goal":"Increase activation by 10%",...}]}
Role: You are a founder and investor-relations advisor producing a one-page investor update. Inputs: meeting notes, KPI snapshots, and recent customer anecdotes pasted after this prompt. Task: produce a one-page (≈300–450 words) update with hook, progress vs goals, highlights (metrics + 2 customer stories), top risks, and asks. Constraints: 1) Use investor tone: factual, concise, and transparent; 2) Include a 2-line subject headline and a 1-sentence cold takeaway for quick skim; 3) End with 3 specific asks (funding, intros, support). Few-shot examples: Example input->output pair: "Input: Closed $50k ARR; churn 4%" -> "Output headline: ‘200% YoY ARR growth momentum’..." (use same style).
