Mem Review, Pricing & Alternatives (2026)

Mem was founded by Kevin Moody and Dennis Xu after they began the company in late 2019, followed by a public product announcement in 2021. The founders reported a $5.6 million seed round led by Andreessen Horowitz and a $23.5 million Series A led by the OpenAI Startup Fund in 2022. TechCrunch reported total funding of $29 million and a $110 million post-money valuation after that round. Mem’s current product is an AI work assistant, not a conventional folder-first notebook. Its stated audience includes entrepreneurs, executives, and creatives seeking capture and retrieval without manual organization. The Free plan includes 25 messages, 25 new notes, tracking across 25 notes, 15 open tasks and projects, and three Voice Mode hours monthly; paid plans begin at $9 monthly.

Mem centers on creating notes, asking questions, and finding related information through search and conversation. Voice Mode records meetings or spoken thoughts and produces structured transcripts and notes. Mem Agent tracks tasks and projects across notes, while Custom Routines can prepare briefings, research, organize notes, and send scheduled reminders. Connections add sources such as Gmail, Slack, or Todoist to context, and Email and WhatsApp provide capture channels. Users can also export Markdown with one click, apply templates, use Deep Search, or open floating chat before asking Mem to connect information. The Free plan includes 25 messages and new notes, tracking across 25 notes, 15 open tasks and projects, and three Voice Mode hours monthly. Paid plans increase these limits and add routines and connections.

Mem 2.0 launched in October 2025 after a reported two-year rebuild. The company says it added full offline support across web, desktop, and mobile, with faster capture and retrieval. Its technology combines a searchable knowledge store with AI processing, task detection, transcription, routines, and external connections. Developer documentation provides bearer-authenticated API keys and an MCP integration compatible with Claude, ChatGPT, Claude Code CLI, Codex CLI, and Gemini CLI. Mem publishes capabilities and limits but does not identify one underlying foundation model or promise a fixed context window. Pricing ranges from Free to $199 monthly, with increasing allowances for messages, notes, tracked notes, tasks and projects, Voice Mode hours, routines, and connections. Extra Usage costs $50 monthly. No later October 2026 release is claimed here.

Mem uses monthly activity limits across messages, new notes, tracked notes, open tasks and projects, Voice Mode hours, Custom Routines, and Connections. The Free plan costs nothing and includes 25 messages, 25 new notes, tracking across 25 notes, 15 open tasks or projects, and three Voice Mode hours. Plus costs $9 monthly and provides 50 messages, 50 new notes, tracking across 50 notes, 25 open tasks or projects, and 10 Voice Mode hours. Pro costs $29 monthly and includes 100 messages, 100 new notes, tracking across 100 notes, 50 open tasks or projects, one Custom Routine, one Connection, and 25 Voice Mode hours. Pro tiers cost $49, $99, $149, or $199 monthly. Each $50 Extra Usage unit adds Pro 20x capacity. Terms allow monthly or annual billing.

Mem’s value depends on trusting a hosted service with material it processes for intelligence features. Mem says data is encrypted at rest with AES-256 and in transit with TLS, but it is not end-to-end encrypted. It says it does not sell data or mine it for advertising, and its privacy policy says MCP queries are not used to train AI models. Mem is closer to Reflect or Notion AI than to a local notebook, while Obsidian offers greater local control and Roam Research emphasizes linked notes. Choose Mem for proactive capture, voice, and task follow-through, not offline ownership or unlimited low-cost notes. The Free plan includes 25 messages and new notes monthly; paid plans start at $9 and impose usage limits that increase with price.
