Otter.ai vs Mem: Features, Pricing and Verdict

Otter.ai and Mem both promise to remember things for you. They solve different problems. Otter.ai is a meeting notetaker. It joins your calls, transcribes them, and turns them into summaries with action items. Mem is a personal memory workspace. It turns your notes, messages, and voice memos into a searchable memory, and its agent tracks tasks and projects across them.

The overlap is real but narrow. Both can capture a meeting. Both can answer questions about your notes. But Otter.ai is built for live meetings, and Mem is built for everything else you write down. Pick the wrong one and you pay for features you never use.

Otter.ai vs Mem at a glance

What Otter.ai does best

Otter.ai joins your meetings. It works with Zoom, Microsoft Teams, and Google Meet. It writes a live transcript, identifies speakers, and produces a summary with action items and an outline. You can ask Otter AI Chat questions about a meeting or across meetings.

The free Basic plan includes 300 transcription minutes a month, with a maximum of 30 minutes per conversation. It includes 20 AI Chat queries a month and 3 lifetime file imports. Live transcription, speaker identification, and the mobile apps are included. One meeting runs at a time.

Pro costs $16.99 per user a month, or $8.33 a month billed annually. It raises the allowance to 1,200 minutes a month and 90 minutes per conversation. It adds 50 AI Chat queries a month, 10 file imports a month, advanced templates, and unlimited history. Students and teachers with a .edu email get 20 percent off Pro.

Business costs $30 per user a month, or $19.99 a month billed annually. It removes the meeting minute cap and raises the conversation limit to 4 hours. It adds 6,000 import minutes, 200 AI Chat queries, 3 concurrent meetings, usage analytics, and Salesforce or HubSpot sync. Enterprise is priced through sales.

The catch is the minute cap. Pro stops at 1,200 minutes, which is 20 hours a month. If you meet more than that, you need Business. The 90-minute conversation cap on Pro also matters for long workshops.

What Mem does best

Mem is a notes workspace with an agent on top. You write notes, send messages to Mem, or email things in. Mem organizes them, tracks tasks and projects it finds in them, and answers questions from your whole collection. Voice Mode turns spoken thinking into structured notes.

Mem prices on a metered ladder, verified on its official pricing page on November 14, 2026. The free plan costs $0 and includes 25 messages to Mem, 25 new notes, task tracking across 25 notes, 15 open tasks and projects, and 3 hours of Voice Mode a month.

Plus costs $9 a month. It doubles the free allowances to 50 messages and 50 notes, with 10 hours of Voice Mode. Pro costs $29 a month and is marked recommended. It allows 100 messages and 100 notes, 50 open tasks, 25 hours of Voice Mode, and adds the first custom routine and the first connection to Gmail, Slack, or Todoist.

Higher tiers scale the same allowances: Pro 2x at $49, Pro 5x at $99, Pro 10x at $149, and Pro 20x at $199 a month. Only Pro 20x can add Extra Usage at $50 a month per block. No annual billing option is listed, so all prices are monthly.

The catch is that every tier has a ceiling. Free stops at 25 notes a month, which is about one per working day. Pro stops at 100 notes and 100 messages. If you write more than that, the price climbs fast. Mem replaced its old flat $12 Pro plan with this ladder during 2026, so older reviews quote prices that no longer exist.

Where they overlap, and where they do not

Both tools can capture a meeting. Otter.ai does it live, as a participant that joins the call. Mem does it through Voice Mode, which records and transcribes what you say. Otter.ai is the better meeting recorder. It handles speakers, long calls, and team sharing.

Both tools can answer questions about your material. Otter.ai answers about meetings. Mem answers about your whole note collection, including email and connected apps. Mem is the better memory. It connects more sources and tracks tasks across them.

Neither tool replaces the other. Otter.ai has no note-taking workspace worth the name. Mem has no live meeting bot, no speaker identification, and no 4-hour conversation support. If you need both jobs done, you need both tools, or you accept a weaker version of one job.

Which one should you choose?

Choose Otter.ai if your problem is meetings. You sit in many calls, you need transcripts and summaries, and you want action items without taking notes. Start free, watch the 300-minute cap, and move to Pro when you pass it.

Choose Mem if your problem is scattered notes. You write things in many places, you lose track of tasks, and you want one searchable memory. Start free, watch the 25-note cap, and move to Plus or Pro when you pass it.

Choose both if you live in meetings and in notes. Otter.ai captures the calls. Mem holds the memory. Together they cost about $17 to $38 a month at the entry paid tiers, depending on billing.

Bottom line

Otter.ai vs Mem is not a fair fight, because they fight in different rings. Otter.ai wins meetings: live transcription, speaker labels, summaries, and action items, from free to $8.33 a month on annual billing. Mem wins memory: notes, tasks, routines, and connections across your whole workspace, from free to $29 a month for the recommended Pro tier. Pick the one that matches your real bottleneck. If your bottleneck is meetings, buy Otter.ai. If it is scattered notes, buy Mem.
