Automatically Discover Relevant Slack Channels
New files are created but nobody knows which channel to discuss them in. Notis searches Slack for channels matching your file name or type, surfacing the right space for collaboration.
Trigger
File Created
Triggers when a new file is created in Google Drive.
Action
Find channels
Find channels in a slack workspace by any criteria - name, topic, purpose, or description.
Why this helps
Neurodivergent founders create files but forget to share them with the right people on Slack. Automatic channel discovery reduces the friction of finding the right collaboration space.
- Automatically discover relevant channels for new files
- Reduce the effort of finding the right channel
- Share files in the right places without hunting
- Improve discoverability by surfacing relevant channels
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Slack to Notis (one-time setup).
- 2Ask Notis 'When new files are created in my Google Drive, find Slack channels matching the file name' or use the portal.
- 3Describe how to match channels (e.g., 'by file name', 'by file type', 'by keywords').
- 4Test by creating a new file and confirm that matching channels are discovered and displayed.
- 5Optionally refine the matching logic (e.g., 'Find channels starting with # that include the project name').
Questions about this workflow
What happens after the channels are found?
Notis will display the matching channels so you can manually share the file or post about it. You can also chain this with an invite automation to join automatically.
Can I automatically join or share in the discovered channels?
Yes. Create a follow-up automation that invites users or posts to channels once they are discovered.
What if no channels match?
Notis will let you know no matching channels were found. You can then manually create or select a channel.

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.
