A lightweight mention reminder for Microsoft Teams
Somebody @mentions you in a Teams channel while you are on a call. You read it, you mean to come back to it, and by the afternoon it is buried under the next twenty posts. Mention Reminder watches the mentions nobody answered and reminds you about them in a private 1:1 chat - at the hours you choose, in your own timezone. Reply in the thread or react to the message, and the reminder clears.
โA team owner adds it in about two minutes, no commands
โReminders arrive in your own 1:1 chat - nobody else sees them
Alex ยท @John can you handle the graphics for Friday? ๐

How it works
How the Microsoft Teams mention reminder works
One team owner adds the app. Everybody else keeps writing exactly as they did before.
Step 1
Add the app to a team
In Teams, open Apps, find Mention Reminder and choose "Add to a team" - not just for yourself. The bot then sends you a one-click link to the web panel to finish setup.
Step 2
Every standard channel is covered
Once the app is in a team, it sees that team's standard channels - there is no inviting it channel by channel. Add it to a group chat too and that chat is watched the same way.
Step 3
Someone @mentions you and moves on
Mention Reminder adds a discreet ๐ to the message so the channel can see it is being tracked - and nothing more. No public nagging, no "any update?" from a bot.
Step 4
You get a private reminder until you answer
At the hours you picked - 09:00 and 17:00, say - the app reminds you in your 1:1 chat with it about the mentions still waiting. A card in that chat always holds the current list.
The details
What it looks like inside Microsoft Teams
The parts that are specific to Teams, rather than to the product in general.
๐ฌWhere reminders arrive
In your own 1:1 chat with Mention Reminder, as a card listing what still waits for your reply, with Open and Done next to each item. The chat opens by itself the first time you are mentioned. Nothing is posted into a channel.
#๏ธโฃWhich channels are watched
The standard channels of every team the app was added to, and group chats it was added to. Private and shared channels are not covered: Teams does not let apps read them.
๐Your timezone
Reported by your Teams client, so 09:00 means 09:00 where you are without anybody filling in a form. Someone in another country gets their own morning, not yours.
๐Several teams at once
Link them on the Team plan and every unanswered mention lands in one list, tagged with the team it came from. A person has one identity across all the teams of your organisation, so they are one seat, not one per team.
๐ฃ@channel, @team and tags
Off by default, on any plan - one announcement should not become a reminder for the whole company. Switch them on with Team and an AI classifier decides which ones actually needed a personal answer.
๐งฐAdmin lives in the web panel
There are no commands to learn. You sign in with your Microsoft account; reminder defaults, who the bot watches and billing are all in the panel, and your own reminder hours are set from the card in your chat.
Self-clearing
It clears itself - you never tidy a list
A reminder that has to be dismissed by hand becomes another inbox. This one closes on the thing you were going to do anyway.
๐ซ It is not a task manager for Teams
Tools that turn messages into tasks only work while everybody keeps turning messages into tasks. This one asks for nothing, because it reads what your team was writing anyway.
No tasks, no assignees, no due dates, no board
Nobody but the admin signs up or logs in
No second app, no extra tab, no notifications from elsewhere
โฉ๏ธ
You reply to the message containing the mention
In a channel, a reply in that post's thread clears your reminder; in a group chat, a quoted reply does the same - even if it just says "ok".
๐
You react to that message
A ๐ or a โ on the message containing the mention clears your reminder.
โ๏ธ
You answer in the channel
On Team, AI may recognize a separate answer in the channel. On Starter, reply in the thread, react to the message, or press Done on the card.
๐๏ธ
The message is deleted
A mention whose message is gone cannot be answered, so its reminders close for everyone who got one. Restore the message in Teams and they come back.
Before / after
The same Teams post, twice
Nothing about how your team writes changes. The only difference is whether anyone still remembers the post on Friday.

Who it is for
Microsoft Teams setups this was built for
Not "better communication" in the abstract - the specific places a mention goes quiet.
Companies that live in Microsoft 365
When every project has its own team and its own channels, mentions are spread across a dozen places. Every unanswered one ends up in a single list in your chat.
Departments with a team each
Sales, delivery and support in separate teams, linked into one account. Each person gets one list and is one seat, however many of those teams they sit in.
Busy channels where posts scroll away
In a channel doing hundreds of posts a week, being mentioned and being noticed are different things. The ๐ is what survives the scroll.
Teams spread across timezones
Reminders are sent on each person's own clock, taken from their Teams client - so nobody has to negotiate when it is acceptable to ping whom.
Testimonials
Teams that stopped losing threads
โ
Odd that Slack does not have this built in. With all the noise, and dozens of people wanting something from you, it helps to have a watcher for whether you forgot to answer someone.
Marketing agency
We keep separate servers for talking to different clients. It is good to have one place that gathers the unanswered mentions from all of them at once.
Software house
Finally a tool that does not need its own panel and manual upkeep to work. Teaching people to use yet another external app is a nightmare.
SEO agency
I like how little work it took to start watching messages - and that the bell emoji shows at a glance which message is being watched, so you see right away that something needs a reply.

Permissions
The permissions it asks for, in full
Teams shows you this list when you add the app. They apply only to the team or chat it was added to, and this is all of it.
๐Minimal permissions
The bot doesn't need admin. It reads the channels you point it at, manages the thread that holds your reminders, and adds reactions - that's it. Your workspace and server stay under your control.
๐คซReminders only you see
Your reminders live in a DM from the bot (Slack) or a private thread (Discord) - nobody on the team sees them. The only public trace is a discreet ๐ on the message.
๐ก๏ธCredentials never make it out
Before an excerpt is stored or a message reaches the AI, anything shaped like an API key, token, or password is replaced with a placeholder. Detection is heuristic - a safety net, not a licence to paste secrets into chat.
๐ Self-host on Enterprise
Enterprise runs on your own infrastructure with local LLMs - message content never leaves your company.
๐ What it asks for
โRead messages in the team's standard channels
โRead the team's member list
โRead messages and members of group chats it is added to

No - an owner of the team adds the app, and that same owner signs in to the web panel with their Microsoft account. Your organisation only has to allow the app in Teams, which is the admin's call and a one-time setting. Everyone else needs nothing at all: no signup, no login, no permission of their own.
No. Teams does not let apps read private or shared channels, so the bot cannot see them at all. It works in every standard channel of the teams it was added to, and in group chats it was added to.
None. Everything an admin configures lives in the web panel, and your own reminder hours are set from the card in your chat with the app. Nobody has to memorise a command or read documentation to be reminded.
In your own 1:1 chat with Mention Reminder, which opens by itself the first time you are mentioned. A card there always holds the current list. Nothing is ever posted into a channel - the only public trace is a small ๐ reaction on the message you were mentioned in.
Yes - your Teams client reports it, so reminders arrive at 09:00 where you actually are. You never fill in a form, and nobody in another country gets your morning instead of theirs.
They are off by default on every plan, so a fresh account tracks direct @mentions only. Switch them on with Team and an AI classifier reads each mass mention and lets through only the ones that genuinely needed a personal answer - an announcement does not become a reminder for fifty people.
Free for one team and up to 5 people on reminders, with one reminder a day and direct @mentions only. A reply in the thread or a reaction on the message clears the reminder. Team adds AI matching for separate in-channel answers and filtering for mass mentions, unlimited people, and linked teams.
Yes, on the Team plan. Mentions from every linked team land in one list, each tagged with its source. A person has one identity across the teams of your organisation, so they are one billed seat, not one per team.
Also available
On Slack or Discord as well?
The same product runs on Slack and Discord, and one account covers all of them. Link them on the Team plan and a person who uses more than one gets one set of reminders instead of several.
Add Mention Reminder to Slack, Teams or Discord - two minutes, once. After that it runs in the background and nobody on the team has to do anything else. Starter is free, no card.
