Flag Slack Messages, Create Linear Issues Instantly
You already know which Slack messages matter. Add a star or emoji and Notis automatically transforms them into Linear tasks. No extra thinking required.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Create linear issue
Creates a new issue in a specified linear project and team, requiring a title and description, and allowing for optional properties like assignee, state, priority, cycle, and due date.
Why this helps
Important Slack messages get lost in the noise because they require a separate context switch to log into Linear. Neurodivergent founders often delay this step indefinitely.
- Create tasks with a single emoji click, no typing required
- Capture high-priority items immediately while context is fresh
- Reduce the friction between noticing something and logging it
- Build a habit of flagging without the burden of manual entry
Setup
Build it in a few focused steps.
- 1Connect Slack and Linear to Notis.
- 2Create an automation by asking Notis: 'When I react to a Slack message with a star, create a Linear issue' or use the portal.
- 3Specify the prompt: 'When a message is reacted to with the star emoji, create a Linear issue using the message content as the title.'
- 4Choose your trigger emoji and Linear team.
- 5Test by reacting to a Slack message with your chosen emoji and watch it appear in Linear.
Questions about this workflow
Can I choose which emoji triggers task creation?
Yes. Star, thumbs up, checkmark, or any emoji you prefer. Pick one that feels natural to your workflow.
Does it capture the entire message thread?
It captures the reacted message and can include thread context in the description if you configure the prompt that way.
Can multiple emojis trigger different Linear actions?
Yes. You can create separate automations for different emojis (e.g., star creates issue, checkmark adds label). This gives you multi-purpose workflow control.
