Mem AI Review 2026: Is the AI Chief of Staff Worth Paying For Now Unlimited Is Gone?

What Mem is in late 2026

Mem started as an AI-first notes app: you write or dump things in, and the AI organizes and retrieves them so you never have to file anything. That core is still there, but the product has been rebuilt twice in two years. Mem 2.0 opened to users in February 2025 and was formally launched with a new brand on October 1, 2025, described by the company as "a completely rebuilt product, a bold new brand".

In 2026 the pitch moved again. The homepage now reads "Your AI chief of staff. Mem Agent builds a living picture of your tasks, projects, and goals". Notes are still the raw material, but the selling point is an agent that tracks commitments, captures meetings "without a meeting bot", reads your calendar and nudges you before things slip.

The company behind it, Mem Labs, was cofounded by Kevin Moody and Dennis Xu. The marketing site lives at get.mem.ai, the web app itself at mem.ai, help at help.mem.ai and developer docs at docs.mem.ai.

• Apps: Mac, Windows, iOS, web, plus a Chrome extension.
• No Android app, and Mem says it has no timeline for one.
• Offline: "Mem works offline and syncs seamlessly across iOS, Mac, Windows, and Web."
• Export: one-click Markdown export of notes and collections.

Mem pricing in 2026: every plan is metered

This is the part of Mem that changed the most. There is no unlimited plan any more. Every tier, paid or free, caps how many messages you send to Mem, how many new notes it creates, how many open tasks and projects it tracks, and how many hours of Voice Mode you can capture. All prices on the pricing page are monthly, and no annual price is published.

• Mem Free - $0: 25 messages, 25 new notes, 25 task-tracking notes, 15 open tasks/projects, 3 hours Voice Mode. No Custom Routines, no Connections.
• Mem Plus - $9/month: 50 messages, 50 new notes, 50 task-tracking notes, 25 open tasks/projects, 10 hours Voice Mode. No Routines, no Connections.
• Mem Pro (recommended) - $29/month: 100 messages, 100 new notes, 100 task-tracking notes, 50 open tasks/projects, 1 Custom Routine with 50 executions, 1 Connection, 25 hours Voice Mode.
• Mem Pro 2x - $49/month: 200 messages and notes, 100 open tasks, 2 Routines (100 executions), 2 Connections, 50 hours Voice Mode.
• Mem Pro 5x - $99/month: 500 messages and notes, 250 open tasks, 5 Routines (250 executions), 5 Connections, 125 hours Voice Mode.
• Mem Pro 10x - $149/month: 1,000 messages and notes, 500 open tasks, 10 Routines (500 executions), 10 Connections, 250 hours Voice Mode.
• Mem Pro 20x - $199/month: 2,000 messages and notes, 1,000 open tasks, 20 Routines (1,000 executions), 20 Connections, 500 hours Voice Mode.
• Extra Usage (Pro 20x only) - +$50/month per block: adds 500 messages, 500 notes, 500 task notes, 250 open tasks, 5 Routines, 250 executions, 5 Connections and 125 Voice Mode hours.

Do the arithmetic before you pick a tier. Mem Pro at $29 buys 100 messages a month, which is a little over three a day. That works out to about 29 cents per message on Pro, 18 cents on Plus and roughly 10 cents on Pro 20x. If you lean on chat to answer questions about your notes all day, the cheaper tiers will run out fast. Mem says it shows you when you are approaching a limit so you can upgrade before work is interrupted.

What happened to the $12 unlimited plan

If you remember Mem as a $12 app with unlimited AI, that plan is gone. Archived copies of the pricing page show how quickly things moved in 2026:

1. June 2026: Free gave 25 notes, 25 chat messages and 25 PDF pages a month. "Mem Pro Unlimited" cost $12/month with unlimited notes and chat, dark mode, AI model selection and beta features. Teams was custom-priced through sales.
2. Summer 2026: Mem Proactive appeared as the recommended tier at $99/month with a 7-day free trial and a 30-day money-back guarantee, while Pro stayed at $12 but was capped at 250 messages to Mem Agent.
3. Late August 2026: the whole lineup was replaced by today's ladder. Pro became $29 with 100 messages, the $99 Proactive tier disappeared, and $99 now buys Mem Pro 5x.

So the plan that used to be called Pro now costs more than twice as much and does far less on paper: 100 messages instead of unlimited. The flip side is that Pro now includes agent features, Routines and a Connection that the old $12 plan never had. Whether that trade is fair depends entirely on how much you use the agent rather than the notes.

The iOS App Store still lists legacy in-app purchase SKUs such as Pro $12 and Proactive $29, $59 and $99 alongside the current ones. Treat those as leftovers for existing subscribers, not as plans you can pick on the website today.

Mem Agent: tasks, projects and nudges

Mem Agent is the reason the pricing changed. Instead of waiting for you to search, it keeps track of what you said you would do and reminds you. The App Store screenshots show the idea well: a nudge such as "You told Dana she'd have the pricing proposal by Friday. It's Thursday - sent it yet?"

• Tasks and Projects arrived in Mem Agent in September 2026 (iOS release 2.6.32), and each tier limits how many can be open at once.
• Push-to-Remember on Mac and Windows lets you speak a thought and have Mem file it.
• Custom Routines run recurring agent jobs, from 1 on Pro up to 20 on Pro 20x.
• You can message Mem through outside channels such as WhatsApp or email, and each one counts as a message.

In practice the agent is only as good as what it can see. On Free and Plus there are no Connections, so it works from your notes, meetings and calendar alone. To let it read Gmail, Slack or Todoist you need Pro, and Pro gives you exactly one Connection.

Meeting notes and Voice Mode

Mem records meetings without sending a bot into the call. The Mac and Windows desktop apps "capture both microphone input and computer audio", so both sides of a Zoom or Meet call end up in the transcript. Calendar sync with Google and Outlook was added in March 2026, and the desktop app can prompt you to let Mem take notes when a meeting starts.

There are real limits. The web and iOS apps only capture your microphone, so on a phone Mem hears you but not the other side. Intel Macs cannot capture system audio at all. And "Right now, Mem Voice Mode only works in English."

Voice Mode is also metered by total captured time: 3 hours a month on Free, 10 on Plus, 25 on Pro and up to 500 on Pro 20x. Twenty-five hours covers roughly an hour of meetings every working day, which is enough for most individual users but tight for someone who lives in calls.

Capture, search and chat

Getting things into Mem is easy. You can type, talk, forward emails to [email protected], or clip pages with the Chrome extension, which adds a side panel where you can tell Mem what to do with what you are looking at. Zapier connects it to more than 8,000 other apps.

Getting things out is where Mem has always been strongest. Deep Search works on every plan, Heads Up "surfaces related notes and collections while you work", and chat answers questions across your notes. Long requests are processed "in batches (around 50 notes at a time)", so a question that has to sweep a large archive can take a while.

Other tools in the box: Collections for grouping notes, Templates, a Clean Up command that tidies rough notes, Version History, a PDF viewer and Copy as Markdown.

Integrations, API and MCP

Mem runs an MCP server at mcp.mem.ai that "works with Claude, ChatGPT, Claude Code CLI, Codex CLI, and Gemini CLI", and a Claude connector was announced in March 2026. That means you can use your Mem notes as context inside another AI assistant rather than only inside Mem.

The REST API allows 100 requests per minute and 4,000 per day, with a separate complexity budget. Note that plan quotas apply here too: the docs say "Usage quotas, such as a plan's monthly note creation allowance, also return 429." Automations that create notes will eat into the same allowance as your manual use.

On AI models, Mem announced in March 2026 that Pro users could choose between Claude Sonnet, Google Gemini and OpenAI GPT. The current pricing page no longer lists AI model selection as a plan feature, so do not count on it when choosing a tier.

Privacy and security

Mem's privacy policy is clear on training: "We do not use your personal information, notes, or the information we collect via third parties (e.g. Google Workspace APIs) to develop, improve, or train any generalized AI and/or ML models." The SOC 2 announcement adds that this covers "any vendor we work with" too.

• SOC 2 Type II compliant since January 2026.
• Encrypted with AES-256 at rest and TLS in transit, hosted on Google Cloud.
• Not end-to-end encrypted: content "is only unencrypted for AI processing with trusted and SOC 2 compliant third-party vendors".
• Subprocessors are listed at the Trust Center, trust.mem.ai.

That is a reasonable setup for work notes, but it is not a zero-knowledge vault. If you need end-to-end encryption, an AI-first cloud tool like Mem is the wrong category; a local-first app is a better fit.

Where Mem falls short

• Metering everywhere: messages, notes, open tasks and voice hours are capped on every plan, and email and integrations draw from the same pool.
• Pro got more expensive: $29 for 100 messages, against $12 for unlimited a few months earlier.
• No Android app and no timeline for one.
• Voice Mode is English-only, and phone or web capture records only your microphone.
• Imports take Markdown or .txt only, about 1,000 files at a time, with no folder structure and no direct Notion, Evernote or Apple Notes importer.
• No published annual price, no free trial and no money-back guarantee on the current pricing page.
• Team plans are by inquiry only, with no listed price.
• Two rebuilds and three pricing models in about 18 months make it hard to plan around.

Which Mem plan should you pick

Start on Free. It includes Deep Search, templates and 3 hours of Voice Mode, and 25 messages a month is enough to find out whether Mem's way of organizing suits you. Remember that the free tier also caps new notes at 25 a month.

• Mem Plus ($9): a light personal notebook with occasional chat and a few meetings a month. No Connections, so the agent cannot see your inbox.
• Mem Pro ($29): the realistic starting point if you want the agent. One Connection, one Routine and 25 hours of meetings, but only about three messages a day.
• Mem Pro 2x or 5x ($49-$99): people who talk to Mem many times a day or connect several sources such as Gmail, Slack and Todoist.
• Mem Pro 10x or 20x ($149-$199): heavy users and executives who want Mem running their day; Pro 20x is the only tier that can buy Extra Usage.

If all you want is a notes app with good AI search, Mem is now hard to justify against a flat-priced tool. Obsidian or Evernote are better homes for a large archive, and a dedicated meeting notetaker like Granola is a closer match if meetings are the main job. Mem makes sense when you actually want the chief-of-staff part: something that reads your notes, calendar and inbox and tells you what you forgot.

Frequently asked questions

How much does Mem cost in 2026?

Mem costs $0 to $199 a month. The tiers are Free, Plus $9, Pro $29, Pro 2x $49, Pro 5x $99, Pro 10x $149 and Pro 20x $199, and Pro 20x users can add Extra Usage at $50 a month. Only monthly prices are published.

Is there a free plan, and what are its limits?

Yes. Mem Free gives 25 messages, 25 new notes, 25 task-tracking notes, 15 open tasks or projects and 3 hours of Voice Mode a month, with Deep Search and templates included. It has no Custom Routines and no Connections.

What counts as a Message to Mem?

Any push-to-talk request, floating chat message, message through an outside channel such as WhatsApp, or email sent to Mem. If an email creates a note, it also counts against your new-note allowance.

What happened to the $12 unlimited Pro plan?

It was replaced in late August 2026. The current Mem Pro costs $29 a month and includes 100 messages, plus agent features, one Routine and one Connection that the old plan did not have.

Does Mem train AI on my notes, and is it end-to-end encrypted?

Mem says it does not use your notes to train AI models, and neither do its vendors. It is not end-to-end encrypted: data is encrypted at rest and in transit, and decrypted for AI processing by SOC 2 compliant third-party vendors.

Is there a Mem app for Android?

No. Mem runs on Mac, Windows, iOS and the web, plus a Chrome extension, and the company says it has no timeline for Android.

Can I import from Notion or Evernote, and can I export my notes?

Not directly. Mem imports Markdown and .txt files only, about 1,000 at a time and without folder structure, so you export from Notion or Evernote to Markdown first. Export is one click to Markdown.

Is there a free trial or refund?

The current pricing page offers neither. Mem's terms say fees are non-refundable with no credit for partial periods, though some refund requests may be considered case by case. You cancel from Settings under your profile picture.

Key takeaways

• Mem is now an AI agent built on your notes, meetings and calendar, not just an AI notes app.
• Every plan is metered; Pro costs $29 a month for 100 messages, 100 new notes and 25 hours of Voice Mode.
• The $12 unlimited Pro and the $99 Proactive tier are gone; $99 now buys Mem Pro 5x.
• Connections to Gmail, Slack or Todoist and Custom Routines start at Pro.
• Notes are not used for AI training, but Mem is not end-to-end encrypted.
• No Android app, English-only Voice Mode and Markdown-only imports are the main gaps.
• Try Free first; pay for Pro or above only if you want the agent, not just the notes.
