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.

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.

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.

ActionInstant

File Created

Triggers when a new file is created in Google Drive.

TriggerPolling

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.

ActionInstant

File Deleted or Trashed

Triggers when a file is moved to trash or permanently deleted in Drive.

TriggerPolling

Add an emoji alias

Adds an alias for an existing custom emoji in a slack enterprise grid organization.

ActionInstant

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.

TriggerPolling

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.

ActionInstant

File Updated

Triggers when a file's metadata or content changes in Google Drive.

TriggerPolling

Add a star to an item

Stars a channel, file, file comment, or a specific message in slack.

ActionInstant

Google Drive Changes

Triggers when changes are detected in a Google Drive.

TriggerPolling

Add call participants

Registers new participants added to a slack call.

ActionInstant

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``.

TriggerPolling

Add emoji

Adds a custom emoji to a slack workspace given a unique name and an image url; subject to workspace emoji limits.

ActionInstant

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.
