Slack is where your team already talks. Stop losing what it decides.
Slack is the best place a team has ever had to talk - and the worst place to keep what the talk concluded. Decisions sink into DMs nobody else can search, and on the free plan history is deleted by design. Naumu keeps the chat feel you already know - threads, @mentions, your agents in the room - on top of a map that remembers, with a receipt on every answer.
Why Naumu holds up
The same chat feel - but the talk lands somewhere.
The conversation becomes the map
In Slack a thread scrolls away the moment it stops moving. In Naumu, threads and messages are nodes in the graph itself - the decision, its reasons, and the work it touches stay linked. Same affordances Slack taught everyone - threads, @mentions, reactions - so the switch costs nothing to learn.
Decisions keep their receipts
Ask “what did we decide, and why?” and the answer comes back with who decided, when, and the thread it came from. In Slack that answer lives in someone’s scroll-back - often a DM that nobody else, not even an admin, can search.
Your agents get a desk, not a window
Slack’s agent ecosystem is genuinely strong - we won’t pretend otherwise. Naumu goes the same direction with fewer gates: Claude and ChatGPT read and write the map as you, and your own agent gets its own identity - paste one bootstrap snippet and any runtime joins the team’s threads as a member.
Watch it work
The decision that would have died in a DM.
A call gets made in a quick huddle; three weeks later someone asks about it in public. Ask your space - or @mention Naumu in the Slack thread itself - and the answer comes back with its receipt.
In Slack, that answer lived in a huddle and two people’s memories. Scripted so you can see the shape - paste your own below and ask.
The honest comparison
Where each tool actually wins.
Here’s the real split - including the rows Slack wins outright, because it wins them by a mile.
Talking in real time
Best in class - channels, huddles, presence, the bar every chat tool is measured against.
Familiar chat - threads, @mentions, reactions - built as the front door to a map, not the whole house.
What a conversation leaves behind
Scroll-back - plus pins and canvases if someone remembers to file them.
Threads and messages are nodes in the graph; the discussion stays attached to what it’s about.
Where decisions live
In the thread where they happened - often a DM or private channel nobody else can search.
As things in the map - linked to their reasons, owner, and date, askable by anyone with access.
Message history
Free hides everything past 90 days and deletes data older than a year, rolling. Unlimited on paid.
The space is the memory - history is the product, not a quota.
Finding it later
Search plus AI answers on paid tiers - over prose, recency-ranked, famously hit-or-miss for old context.
Ask in plain language; answers walk the actual connections, with a source and timestamp attached.
When someone leaves
Their DM knowledge stays locked to whoever was in the room.
What they logged lives in the shared map, attributed - the context stays when the person goes.
Your AI assistants
Genuinely strong - Slackbot, agent apps, an official MCP server (Marketplace apps, admin approval).
Claude and ChatGPT read and write the same map as you - one shared memory, every assistant.
Bringing your own agent
Real, but it’s an app: build against the agent APIs, list it or install it, get admin approval.
Mint an identity, paste one bootstrap snippet, point any runtime at it - it joins threads as a member.
Cross-company chat
Slack Connect is unmatched - shared channels across a hundred thousand organizations.
Not the job - invite guests to a space, but there’s no cross-org channel fabric.
App ecosystem
Thousands of Marketplace apps; if a tool exists, there’s a Slack app for it.
A younger set of connectors - Linear, Jira, ClickUp, and Slack itself - plus MCP for the rest.
Trying it
Free to join - but the value only shows once your whole team moves in.
No signup to try - the map builds in front of you; Keep it (one tap, no email) if it earns it.
If what your team needs is the best real-time chat ever built - huddles, Connect channels with clients, an app for everything - use Slack; nothing here pretends otherwise, and Naumu connects to it rather than fighting it. Naumu is for what Slack loses on purpose: the decisions, reasons, and receipts the chatter produces. Keep talking where you talk - and give the talk somewhere to land.
Better together
Try Naumu with the Slack you already have.
You don’t have to pick a winner today - there’s a real Slack connector. An admin installs the Naumu app on your workspace, each teammate links their account once, and from then on Naumu is in the room: DM it or @mention it in any thread and it answers from your space and files what matters into the map.
Conversations live on both sides
Every Slack conversation maps to a Naumu thread, so the same discussion stays current in both tools - nothing is moved or deleted in Slack.
Ask from either side
@mention Naumu in a Slack thread or ask in the app - same map, same receipts. The answer lands where you asked.
Decide later, or never
Run both for as long as you like. If Naumu earns the talk itself, move it; if not, you still keep a map of what your Slack decided.

Stop scrolling. Start asking.
Connect your Slack workspace, paste a week of one busy channel, or start with one decision worth keeping. Naumu gives the talk a map to land in - and answers with receipts from then on.
