# Team Messaging, Channels, and File Sharing in Fluorine

> Message your team, share files, and link conversations to tasks — all in one place, with AI that turns discussions into action items automatically.

Your conversations and your work live in the same place in Fluorine. Reference tasks directly in messages, share files in context, and let the AI Copilot watch your channels and pull out action items automatically — no copy-pasting decisions into a task manager at the end of every meeting.

## Sending messages

Messages are organized into channels inside your team spaces. Every member with access to a space can read and send messages in its channels.

<Steps>
  <Step title="Open a channel">
    Select a channel from the sidebar. Click **+** next to **Channels** to create a new one.
  </Step>

  <Step title="Write your message">
    Click the message input and type. Markdown works — **bold**, *italic*, `code`, bullet lists.
  </Step>

  <Step title="Send">
    Press `Enter` to send. `Shift+Enter` for a new line without sending.
  </Step>
</Steps>

## Linking messages to tasks

Keep context in both places — the conversation and the task.

* **Reference a task:** Type `#` followed by the task name to create an inline link. Click it to open the task without leaving the channel.
* **Create a task from a message:** Hover over any message and click **Create task**. The message becomes the task description and a link back to the conversation is saved automatically.
* **See linked messages from a task:** Open any task and scroll to **Linked messages** to see every message that references it.

<Tip>
  The AI Copilot watches your conversations automatically and creates tasks when it detects action items — no manual linking needed. See [AI Copilot](/features/ai-copilot).
</Tip>

## File sharing

Share files directly in any message or channel.

* **Attach a file:** Click the paperclip icon or drag and drop into the channel
* **Preview inline:** Images and PDFs preview directly in the thread — no download needed
* **Search files:** All shared files are indexed and searchable in plain language — try "the brand guidelines PDF from last month"

<Note>
  File storage counts toward your plan limit. Check **Settings → Storage** to see current usage.
</Note>

## How the AI Copilot monitors conversations

The AI Copilot runs in the background across all your channels and does three things automatically:

* **Task creation:** Detects commitments, requests, and action items in messages — then creates a task, assigns it to the right person, and sets a due date
* **Smart summaries:** After busy threads or meetings, surfaces a concise summary with key decisions and next steps
* **Semantic search:** Search across all messages, tasks, and files in plain language — no exact keywords needed

## Channel tips

<AccordionGroup>
  <Accordion title="Organize by topic, not by person">
    Name channels around projects or workstreams — `#brand-refresh`, `#q3-launch`, `#engineering` — not around individuals. Keeps everything searchable and visible to the whole team.
  </Accordion>

  <Accordion title="Pin important messages">
    Hover over a message and click **Pin** to keep it at the top of the channel. Good for briefs, kickoff notes, and decisions that everyone needs to find quickly.
  </Accordion>

  <Accordion title="Archive instead of delete">
    When a project wraps up, archive its channel rather than deleting it. Archived channels stay searchable but disappear from the sidebar.
  </Accordion>

  <Accordion title="Move cross-channel work into tasks">
    If a conversation spans multiple channels or pulls in several people, turn it into a task. Tasks are the permanent record — messages are the real-time discussion layer.
