Revisit image descriptions when docs change
When a page's body changes, search for relevant images and their existing alt text, so updates to the story do not leave asset context behind.
Trigger
Page Content Updated
Triggers when the body content of a Notion page is updated. Customer optionally scopes with at most one of: - data_source_id: any row in this data source - page_id: this specific page - parent_page_id: any page whose immediate parent is this page With none set, fires for any page content edit in the workspace the integration has access to. Notion aggregates content edits within a short window (~60s typical).
Action
Search Images
Tool to search for images and their alt text. use after specifying search keywords to retrieve matching images.
Why this helps
Edited documentation can change what an image means, but the image library may not get another accessibility review.
- Recheck images when document context shifts.
- See current descriptions next to newly updated information.
- Make accessibility review part of normal documentation upkeep.
Setup
Build it in a few focused steps.
- 1Connect Notion and Alttext.ai to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to set it up conversationally.
- 3In one instruction, ask Notis to search Alttext.ai for images related to an updated page and report their current alt text for review.
- 4Pick the Page Content Updated trigger, optionally scoped to a relevant page or data source, and select a report channel.
- 5Test by editing a page with a distinct subject.
Questions about this workflow
Does every edit trigger a separate search?
Notion aggregates content edits over a short window, so closely grouped changes may arrive together.
Does the workflow update image descriptions?
No. It finds images and reports their current alt text for a person to review.

Supported Triggers and Actions
Notis builds workflows that link Notion to Alttext ai. A trigger fires from one place; an action lands in another.
Notion triggers
Alttext ai actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Get Account
Tool to retrieve account settings and usage information. use when you need to check your alttext.ai account configuration and usage limits before generating alt text.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Get Account
Tool to retrieve account settings and usage information. use when you need to check your alttext.ai account configuration and usage limits before generating alt text.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Get Images
Tool to retrieve a paginated list of images in your library, including their alt text and metadata. use when you need to browse or filter images programmatically after authentication.
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.
Search Images
Tool to search for images and their alt text. use after specifying search keywords to retrieve matching images.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Update Account
Tool to update account settings (e.g., webhook url, name). use after confirming current account details to modify settings.
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.
