Train Nano nets from document examples in Notion
Keep document training examples together in Notion, then send each new approved example to the right Nano nets OCR model automatically.
Trigger
New Page
Triggers when a new page is added to a Notion database.
Action
Upload Training Images by File
Tool to upload training images by file to a specified ocr model. use when adding files to a model for training purposes.
Why this helps
Gathering example files for OCR training by hand makes it easy to lose track of what has already been added.
- Reduce the repeated download-and-upload routine.
- Keep the Notion example page as the starting point for training.
- Use a consistent instruction to identify the intended OCR model.
Setup
Build it in a few focused steps.
- 1Connect Notion and Nano nets to Notis once through the portal.
- 2Create an automation in the portal or ask Notis in plain language to send approved Notion examples to Nano nets for OCR training.
- 3Choose the Notion New Page trigger for the database that holds your examples.
- 4Choose where Notis should report runs, then test with one real example file.
Questions about this workflow
Does this workflow train the OCR model automatically?
It uploads training images to the model. The available Nano nets action is for uploading images, not for starting model training.
Can I send an image from a Notion page?
Use a prompt that tells Notis to identify the relevant image or file on the new page and upload it to the intended model.

Supported Triggers and Actions
Notis builds workflows that link Notion to Nano nets. A trigger fires from one place; an action lands in another.
Notion triggers
Nano nets actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create OCR Model
Tool to create a new ocr model. use when you need to initialize an ocr model before training.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Delete OCR Model
Tool to delete an ocr model. use when you need to permanently remove a trained model by its id.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Get all OCR models
Tool to retrieve a paginated list of all ocr models. use when you need to inspect or manage existing ocr models. call after authentication to fetch your account's models.
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.
Get All Prediction Files
Tool to fetch all prediction files associated with a specific model. use when you need to list all inference requests after model processing is complete.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Get OCR Model Details
Tool to retrieve details of an ocr model. use when you need full metadata of a model by its 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.
Get OCR Training Images
Tool to retrieve training images for an ocr model. use when you need to page through images associated with a model before training or analysis.
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.
Get Workflows
Tool to retrieve a list of all workflows in your nanonets account. use when you need to inventory or inspect all configured workflows.
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.
List Workflow Documents
Tool to retrieve a paginated list of documents processed by a workflow. use when you need to view documents after processing.
