What is Mem
Mem is an AI-powered notes and knowledge workspace designed to capture information, retrieve it through search and chat, and proactively surface useful context. It combines personal knowledge management with an AI assistant rather than relying on a folder-heavy filing system.
Core offerings
- Notes, collections, templates, and connected email capture.
- AI chat, deep search, and PDF understanding.
- Model selection, API keys, and beta meeting briefings on the paid plan.
- Mem Proactive with an agent that tracks decisions, open loops, meetings, and deadlines.
Pricing
As of August 26, 2026, Mem’s official pricing page lists Free at US$0, Mem Pro at US$12 per month, and Mem Proactive at US$99 per month after a seven-day free trial. The accessible pricing copy does not state a separate annual billing rate, so none is inferred.
Free includes 25 notes per month, 25 chat messages per month, and 25 PDF pages that can be understood in search and chat. Mem Pro removes those caps with unlimited notes, chat messages, deep searches, collections, templates, connected emails, API keys, and PDF understanding. It also adds dark mode, AI model selection, and beta meeting briefings.
Mem Proactive includes everything in Pro plus Mem Agent, which learns from saved material, tracks details, decisions and open loops, prepares briefings before meetings and deadlines, checks in when action is needed, and resurfaces relevant notes with context.
Model footprint
Mem includes AI model selection on Pro but does not publish a fixed vendor-by-vendor model list on the pricing page. Buyers should assess retrieval quality, connected sources, and proactive assistance rather than expecting a public API model catalogue.
Why select Mem
Mem is worth considering for people who want notes, retrieval, and AI assistance in one lightweight workspace. Its free tier is suitable for evaluation, Pro removes the core usage limits, and Proactive adds a higher-touch agent for ongoing personal follow-through.
