Save important messages for meaning-based search
Mark a useful message with a reaction and generate an embedding for a connected search system to use.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Generate Text Embeddings
Tool to convert text into vector embeddings for feature extraction, semantic search, and similarity tasks. Use when you need numerical representations of text for ML applications.
Why this helps
Reference material gets lost when the only way to find it is remembering the exact phrase.
- Flag useful material with a familiar Slack reaction.
- Prepare message text for semantic retrieval.
- Reduce dependence on remembering exact wording.
Setup
Build it in a few focused steps.
- 1Connect Slack and Hugging Face to Notis once using the portal.
- 2Create a named automation through the portal or by asking Notis conversationally.
- 3Write one prompt asking Notis to generate Hugging Face embeddings when your chosen reaction marks a message for search.
- 4Select Message Reaction Added and choose a channel for run reports.
- 5Test with a real reference message and confirm your downstream system can use the embedding.
Questions about this workflow
Does Hugging Face store the message for search?
The embedding action creates vector representations. A storage and retrieval system must be available for later search.
Can I choose which reaction to use?
Yes. The Slack trigger supports optional emoji filtering; describe the reaction convention when creating the automation.

Supported Triggers and Actions
Notis builds workflows that link Slack to Hugging Face. A trigger fires from one place; an action lands in another.
Slack triggers
Hugging Face actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Change Discussion Status
Tool to change the status of a Hugging Face repository discussion. Use when you need to open or close discussions on models, datasets, or spaces.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Check Dataset Validity
Tool to check whether a specific dataset is valid on Hugging Face Hub. Use when you need to determine what features (preview, viewer, search, filter, statistics) are available for a dataset.
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Check Models Upload Method
Tool to check if files should be uploaded through the Large File mechanism or directly. Use when preparing to upload files to a Hugging Face model repository to determine the appropriate upload method for each file.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Check Spaces Upload Method
Tool to check if files should be uploaded through the Large File mechanism or directly to Hugging Face Spaces. Use when preparing to upload files to a Hugging Face Space repository to determine the appropriate upload method for each file.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Claim Paper Authorship
Tool to claim authorship of a paper on Hugging Face. Use when you need to associate yourself or another user with an ArXiv paper.
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Request Repository Access
Tool to request access to a gated repository on Hugging Face Hub. Use when you need to submit an access request for models, datasets, or Spaces that require approval. The fields required vary by repository.
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Create Collection
Tool to create a new collection on Hugging Face. Use when you need to organize and curate models, datasets, spaces, papers, or other collections into a named collection.
Reaction Added Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
Create Datasets Branch
Tool to create a new branch in a Hugging Face dataset repository. Use when you need to create a branch for versioning or experimentation with dataset changes.
Connect any two apps with Notis in the middle.
