Connect your Slack workspace to Melius to bring Mel, the Melius Slack bot, into your team’s channels. Mention Mel in any channel to start generating images, video, audio, and text — the results land on a Melius canvas you can open from the thread.

​
Install the bot

To install Mel in your Slack workspace, you need to be:
  • A team owner or admin on Melius, and
  • A Slack workspace admin (or have permission from your Slack admin to install apps).
1

Open Settings in Melius

In Melius, go to Settings and find the Slack integration.
2

Connect your workspace

Click Connect Slack. You’ll be redirected to Slack’s authorization screen.
3

Authorize Mel

Review the requested permissions and click Allow. You’ll be returned to Melius with the workspace connected.
Each Melius team can be connected to one Slack workspace. Anyone in that Slack workspace who also has a Melius account on the connected team can use Mel.

​
Use Mel in Slack

​
Start a new thread

Mention @Mel in any channel where the bot is present, along with your prompt: 
@Mel make me a product shot of our new sneaker on a marble background
Mel replies in a thread under your message and begins generating. When the result is ready, Mel posts it in the thread along with an Open canvas button that takes you straight to the Melius canvas where the work lives.
Mel needs a prompt with the mention. A bare @Mel with no instruction will be rejected.

​
Continue mid-thread

You can pull Mel into any existing Slack thread by @Mel-mentioning it. Mel will pick up the conversation from there — replies, follow-ups, and new instructions all stay scoped to that thread. Within a thread you can:
  • Ask follow-ups in plain language (“make it warmer”, “try a vertical version”).
  • Drop in images or files as references — Mel ingests attachments.
  • Answer Mel’s clarification prompts using the inline buttons it posts.

​
How threads map to canvases

Each Slack thread corresponds to exactly one Melius canvas.
  • A new @Mel mention always starts a new Slack thread. The thread can be tied to a new canvas or to an existing project or canvas.
  • Follow-up mentions in the same thread keep adding to the same canvas, so iteration stays in one place.
Mel posts an Open canvas link in the thread so anyone with access can jump from Slack to the full canvas view in Melius, where they can keep editing, branching, or sharing the result.
To use Mel from Slack, you need a Melius account on the connected team with edit access to the canvas. Viewers can browse generated results in Slack but can’t trigger new generations.
