Add Visual Markers to Your Comment Notifications
Flat notification lists blur together. Notis automatically adds emoji reactions to Slack messages about new comments, making important feedback visually distinct.
Trigger
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Neurodivergent founders struggle to visually organize and prioritize feedback in long Slack threads. Emoji reactions provide visual markers that reduce cognitive load when scanning conversations.
- Visually distinguish comment notifications in Slack
- Create lightweight markers without clutter
- Improve scannability of long threads
- Use emoji as a quick visual reference system
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Slack to Notis (one-time setup).
- 2Ask Notis 'When a comment is added to my Google Docs, add a comment emoji reaction to the Slack message' or use the portal.
- 3Choose which emoji to use and name your automation.
- 4Test by adding a comment to a document and watch the emoji reaction appear on the Slack message.
- 5Adjust the emoji or rule if needed (e.g., 'Use different emojis for different file types').
Questions about this workflow
Can I use different emoji for different types of comments?
Yes. Describe the rule in your automation prompt, like 'Use checkmark for approved comments and warning for urgent feedback.'
Will this react to existing messages or only new ones?
Only new Slack messages created after you enable the automation will get reactions.
Can I combine this with other comment automations?
Absolutely. You can have multiple automations for comments - one that posts to Slack, one that adds reactions, and one that creates reminders, all working together.

Supported Triggers and Actions
Notis builds workflows that link Google Drive to Slack. A trigger fires from one place; an action lands in another.
Google Drive triggers
Slack actions
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Set snooze duration
Deprecated: turns on do not disturb mode for the current user, or changes its duration. use `set dnd duration` instead.
File Created
Triggers when a new file is created in Google Drive.
Add a custom emoji to a Slack team
Deprecated: adds a custom emoji to a slack workspace given a unique name and an image url. use `add emoji` instead.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
Add an emoji alias
Adds an alias for an existing custom emoji in a slack enterprise grid organization.
File Shared (Permissions Added)
Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
Add a remote file
Adds a reference to an external file (e.g., google drive, dropbox) to slack for discovery and sharing, requiring a unique `external id` and an `external url` accessible by slack.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Add a star to an item
Stars a channel, file, file comment, or a specific message in slack.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
Add call participants
Registers new participants added to a slack call.
New File Matching Query
Triggers when a new Google Drive file matches a provided query. This is the legacy query-centric trigger: it preserves Drive API query config such as ``corpora`` / ``driveId`` aliases and emits the historical ``file_matching_query`` event type. ``FileCreatedTrigger`` covers the broader "new file" case and emits ``file_created``.
Add emoji
Adds a custom emoji to a slack workspace given a unique name and an image url; subject to workspace emoji limits.
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
