Turning what your team says into what happens next shouldn't take discipline.

In Slack, every decision turns into a Notion doc, a Linear ticket, a prompt for every agent, and an explanation for whoever missed it. You're never sure anyone heard you, teammates still get lost, and agents build the wrong thing anyway. Reintersect is team chat that keeps track of what you decide while you talk, so all of that goes away.

Talk like you do in Slack.Quit your second job.

Slack

Slack just stores messages.

Turning “deal 👍” into a doc, a ticket, and a prompt is still up to you.

After the chat, someone asks Claude what was decided. It searches Slack three times, finds conflicting messages and can't say which is final. Someone pastes the thread into Claude Code and tells it to search Slack too. It goes with the older five-step tour v2, and its pull request for five steps has to be caught in review. Someone edits CLAUDE.md, an onboarding skill file and brain/decisions.md by hand to say three steps. The Notion page still says five steps. Maya edits the Linear ticket again and again, and Leo still can't tell which thread it means. The Granola notes from the sync are visible only to the person who took them and still say “fewer steps?”. The team's company-brain bot, synced a moment ago, finds Tuesday's message but still answers five steps, because the stale Notion page and the old #design post outrank it. Slackbot reminds Maya to update the doc, the ticket and the prompt, and a sync gets booked to confirm what was already decided. In the next morning's standup, Maya lists all of that as yesterday's work and names finding the thread as the blocker. On Monday Priya asks whether the tour is staying, Maya explains it again, and Leo finds out the Notion doc is wrong.

Reintersect

Reintersect does the second job.

The conversation is the doc, ticket, and prompt.

Reintersect sorts the same chat into the Onboarding tour conversation and moves it to Agreed once Leo and Sam agree, so nobody files a ticket. Maya says deal and makes it a decision, Keep the product tour, cut to three steps, then tells @Reintersect to do it, with no prompt. The conversation moves to Doing and Reintersect replies that it'll cut the tour to three steps. Its Claude Code run already has the conversation and the decision, so nobody briefs it, and it opens a pull request for three steps. When Sam merges it, the conversation moves to Done. When Priya asks on Monday, the decision shows up under her question.

Slack hears everything your team says and understands none of it.

Slack has no idea what's going on.

In Slite's survey, 56% of teams said their company knowledge sits in Slack threads. But a Slack message is only a name, a channel, and a timestamp, with nothing to say what got decided, who's doing what, what's blocked, or what changed since Tuesday. Linear and Notion only know what someone thought to write down, or to tell an agent to write down, and that copy is out of date as soon as the chat moves on.1

Slack won't let anything else remember for you.

Slack's API terms bar outside apps from storing or indexing messages, which cut Glean off in 2025. So every agent, Slackbot included, has to go through Slack's search and rebuild each answer from scratch. Claude in Slack gets by on notes it writes for each channel, and it can't full-text search its own past sessions.23456

Every workaround turns into everyone's job.

A founder on Hacker News wrote up a Slack decision in Notion, shared the link, and two days later heard “oh, I didn't see that message.” In Slite's survey, 55% of teams that built their own company brain gave up, almost always over upkeep. When facts changed, an agent working from its own memory got 77% right, against 92% with the full history.718

Somebody on your team does all of this today.

SlackReintersectReintersect
Catching up on what you missed You, scrolling every channel since Friday. Tells you what needs you and what moved while you were away.
Joining a call late You, asking someone to recap the first ten minutes. Catches you up on what the room settled and asked before you joined.

Turning a thread into a doc and a ticket You, or an agent you remembered to ask. Drafts the Decision from the chat with its sources, and an agent files the ticket without a prompt.
Updating tickets when plans change Someone, fixing tickets an agent filed from half a thread. Nothing to update. Each conversation tracks its own status, with or without Linear.
Fixing notes that went out of date Whoever spots the stale line in CLAUDE.md or the wiki. Replaces the old fact when someone says something newer.
Briefing coding agents You, pasting context into every session. Briefs Claude Code and Codex on what the team said and decided, and saves what they learn.
Following up after a call The host, turning the huddle canvas into tasks.9 Files each topic into its conversation, with next steps and open questions.
Chasing what people said they'd do You, with /remind and one more DM. Reminds whoever promised on the due date.

Paying for AI 15 Slackbot messages a week on Business+, then Salesforce credits per action.10 Runs agents on the Claude or ChatGPT plan you already pay for.
Working with partners Your partners, each paying for Slack to share a channel.11 Partners reply from Slack or Discord and pay nothing.

Already patched Slack with Claude, Linear, or Notion?

Each one works from the slice of chat somebody tagged, connected, or copied into it.

Good atStill on youReintersectWith Reintersect
Claude in Slack A shared @Claude in each channel that takes on tasks with your tools and code, and learns as it goes. Re-explaining anything outside its short notepad, since it can't search its own past sessions.12 Claude or Codex use the context graph to search every conversation, call, and Decision, and the whole team steers the run.
Slackbot A personal agent that searches your whole Slack and calls MCP tools. Rationing 15 messages a week on Business+, or paying Salesforce per action.10 Runs on your own Claude or ChatGPT plan. When your limits run out, a teammate can share their plan with you.
Cursor or Devin in Slack Starts a coding run from a Slack thread. Pasting in whatever happened outside the thread, every run. The run gets the conversation, its Decision, and every file, call, and linked PR, plus anything relevant from other circles.
Linear in Slack @Linear files issues from a thread and syncs comments both ways.13 Remembering to tag @Linear. Anything nobody tags stays buried in the thread. Syncs with Linear if you want, though you won't need it. Every conversation already tracks its own status.
Notion Long docs, plus Notion AI search across a year of Slack on Business plans. Editing the Notion page every time the team changes its mind in Slack. Notion AI can search Slack, but new messages take up to 3 hours to show up, and it only edits the page when someone asks.14 Writes up what the team decided as you chat, and updates it when you change your mind.
Supermemory and other memory layers Syncs Drive, Gmail, Notion, GitHub, and Granola into one memory. Copying Slack decisions into a doc, since there's no Slack connector.15 Learns from every message, call, and coding session as it happens. Change your mind in chat, and Claude Code and Codex have the new answer by their next prompt.
A company brain you built Built your way, under your control. Feeding and fixing it. Over half the teams that built one gave up because of the upkeep.1 Ask both the same question and see which one knows.

“No one on our team has time to track all our iterations and micro decisions. Since moving to Reintersect, we noticed our conversations shifted from quick questions and repeating stuff to discussing bigger things because everyone (even Claude/Codex) was already on the same page.”

Should you switch?

Switch if

  • You ship with Claude Code or Codex, and briefing them is now the slow part.
  • You change plans often, and somebody always finds out last.
  • Someone updates Notion and Linear after every decision, and they're still out of date.
  • You have meetings to confirm or rehash what you already decided in chat.
  • One person spends their day catching everyone else up.
  • New teammates stay lost for weeks.

Stay on Slack if

  • You need enterprise features we don't have yet.
  • You're fine waiting on whoever writes the doc, files the ticket, and briefs the agent.

Moving over

Bring your Slack history.

When you import from Slack or Discord, Reintersect will read all your conversations and learn from them. By the time your team is here, all your channels and messages are here too. We'll structure them into threads and assign them the right statuses on day 1.

Your partners don't have to switch with you.

You can keep talking to your partners whether they're on Slack, Discord, or Reintersect. We'll still structure the conversations that you have and keep your agents in the loop.
