Keep Issue Discussions Unified Across Platforms
Your team discusses issues in Slack, but the decisions live in Linear. Notis bridges that gap by automatically adding Slack discussion updates as Linear comments, so nothing gets lost.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Create a comment
Creates a new comment on a specified linear issue.
Why this helps
Neurodivergent founders struggle when critical context is scattered between Slack and Linear, requiring multiple platform checks to understand the full picture of each issue.
- Keep all issue context in one place instead of scattered across platforms
- Reduce the cognitive load of tracking conversations in multiple apps
- Ensure no decision or update gets lost between Slack and Linear
- Create a unified audit trail of all issue progress
Setup
Build it in a few focused steps.
- 1Connect Slack and Linear to Notis.
- 2Tell Notis: 'When a message is posted in #project-channel, add it as a comment to the matching Linear issue' or create in the portal.
- 3Provide the prompt: 'For messages in [channel], find the related Linear issue and add the message as a comment with the sender name.'
- 4Choose your Slack channel and confirm the matching Linear project.
- 5Test by posting a message in Slack and verifying it appears as a comment in the corresponding Linear issue.
Questions about this workflow
How does Notis know which issue to comment on?
You tell Notis in your prompt. For example, 'If the message mentions an issue ID, comment on that issue' or 'Comment on the issue from the channel description'.
Does this work for threaded conversations?
Yes, Notis can be configured to capture thread messages as well. Specify in your prompt if you want main channel messages, threads, or both.
Can I exclude certain types of messages?
Absolutely. You can filter by keyword, sender, or message type in your prompt.
