What is Mem?
Mem helps users save notes and web pages and retrieve information by asking questions. It also transcribes and structures meetings, identifies tasks in notes, and prepares recurring reminders and searches.
According to its documentation, Mem lets you:
- save notes and web pages
- find information by asking a question
- transcribe and structure a meeting
- identify tasks in notes
- prepare reminders and recurring searches
We file it under Note-taking and knowledge bases, the category of tools to organise notes and knowledge, and it also overlaps with productivity and organisation and meeting assistants. The category lists 14 verified tools on this site.
The publisher is Mem Labs Inc.. The service launched in 2021, which gives it some track record.
Who is it for?
It is mostly useful to these profiles: small business owners, project managers, researchers, and freelancers. The need it covers is simple to state: organise notes and knowledge.
Mem is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
- you also work from your phone
Before deciding, run a trial on a real task and measure the time saved: it is the only criterion that really counts.
How much does Mem cost?
Pricing model: freemium (limited free use, then paid). A free plan is offered, usually limited in volume or features.
The first paid plan costs $9 per month (Mem Plus, displayed monthly price), according to the pricing page, checked on October 24, 2026.
Per month, that is close to the category median ($9 per month, based on tools with a published price).
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
The publisher does not clearly state where data is hosted. Assume your content may leave your region.
For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.
Exporting your content: Markdown pour les notes et collections. Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
Mem runs on: web browser, iPhone and iPad, browser extension, and API.
Interface languages: English.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
How we scored it
Our 65/100 score does not judge output quality: it measures what can be publicly verified about access to the tool, its openness and how far the publisher can be trusted.

|---|---|---|
| Access | 25/30 | free tier, published price, French interface |
| Openness | 20/30 | API, data export, open code |
| Trust | 20/40 | identified publisher, declared hosting, age, presence in reference lists |
