Keep important Notion comments from disappearing
Make a useful comment easier to revisit when the conversation moves on.
Trigger
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
Action
Create Note
Tool to create a new note in mem. use when you have note content and optional metadata ready to be saved. supports idempotent creation via memid.
Why this helps
A small request hidden in a comment can be missed when attention shifts to the next task.
- Keep notable requests searchable outside the comment thread.
- Preserve enough page context to understand the comment later.
- Lower the effort of returning to open questions.
Setup
Build it in a few focused steps.
- 1Connect Notion and Mem to Notis once through the portal.
- 2Create an automation with one plain-language instruction to save each useful new comment and its page context as a Mem note.
- 3Choose the Notion Comment Created trigger and ensure the Notion connection has Read comments access.
- 4Choose a reporting channel and test with one real comment.
Questions about this workflow
Does Notion need an extra capability for comment events?
Yes. The Notion integration needs Read comments access, and an older connection may need reauthorization after that capability is enabled.
Can comments be limited to one page?
The trigger can be scoped to a specific page, or left workspace-wide.

Supported Triggers and Actions
Notis builds workflows that link Notion to Mem. A trigger fires from one place; an action lands in another.
Notion triggers
Mem actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create Collection
Tool to create a new collection in mem. use when you want to group related notes into a dedicated collection after confirming the title.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create Note
Tool to create a new note in mem. use when you have note content and optional metadata ready to be saved. supports idempotent creation via memid.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Delete Collection
Tool to delete a mem collection. use after confirming the collection id you wish to remove.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
Delete Note
Tool to delete a specific note. use when you need to remove a note by its unique identifier after confirming the note id.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Read Note
Tool to retrieve the content and metadata of a mem note. use after confirming you have the note's id.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
