Extra filter option for queues

2. Updates in integration

Sharing documents with Metamaze has been made easier by providing 2 new integration possibilities: SharePoint & SFTP.

These integrations are an on demand feature, when you need any of them, don’t hesitate to contact

3. Annotation updates

Data masking

When privacy is of the utmost importance, a nifty feature has been added to Metamaze which allows you to mask sensitive data. The production data is handled as it should be, no special things happen there. When the document is sent towards the training set, however, the data is replaced with random but still relevant data. This is achieved by using the correct data masking type.

Merge occurrences

Sometimes you would like to merge all the occurrences of an entity into a single field for your output. From this release on this can be done by using the new setting in the entity configuration. Simply enable the option to get the merging going.

4. Training updates

Speed improvement

Our DevOps team has been working hard to improve the training process. They worked their magic and accomplished an astonishing 20 times speed improvement! Get those documents reviewed and train the model to get an improved model faster!

5. Security updates

Okta login

We support Okta as an identity provider.

More than 14,000 global brands trust Okta to secure their digital interactions with employees and customers.

Release 2.1


Release 2.1

Task module revamped

The quality of your training data determines how well the predictions are of your model. It is, in other words, of utmost importance to perform regular quality checks especially before (re)training a model. We have created a – tasks – module around this where annotated documents can be easily reviewed. In this release, we have improved the ease of review by adding hints (“misannotation hints”). These will suggest annotations that might be missing or redundant. Also we have worked on simplifying annotation tasks by adding predictions to unlabelled documents once a training is present (“model assisted labelling”). This will help the user with annotations. By not annotating from scratch, the user can save a significant amount of (annotation) time.

  • – Redesign create task modal
  • – Model assisted labelling is added with annotation tasks (in case of a trained model)
  • – Misannotation hints are enabled with review tasks (in case of a trained model)

Example of a misannotation hint

Example when the hint was approved by the user (annotation updated)

Export to CSV

Besides JSON we support CSV as an output format for all data extracted, validated and enriched by Metamaze.

Other improvements

Use suggested tasks also when no training is present

We add suggested tasks when no training is present since before you train your first model, you will want to annotate uploaded documents so that afterwards you can review those annotated documents. What easier way is there than doing this using a task?


The review of a failed document is made more intuitive

When reviewing a failed document, you will be able to easily reuse the failed reason by confirming the failed status as well as unmarking the document as failed.


Release 2.0


Release 2.0

Creating your own custom document type, as a business user, has been a common practice in Metamaze. With this release, we go one step further and give the user the possibility to re-use an existing model via our interface. This is a powerful functionality for corporations who want to build further on work done for a specific department in a certain country or for partners who like to incorporate their own created model in client projects.

Document type is added as a new level

Document types are added to the overview page

Besides creating a new document type, it is also possible to add an existing document type to a project

For an existing document type, the user can choose per project which entities to reuse and/or new entities to add

Document type settings are introduced where organizations can be managed/added who have access to the doctype

Other improvements

The steps to create a project are simplified

Time needed to create a project is even lower than before


Name of logged-in user and organization are added to the navigation bar

Instead of ‘user’ and ‘system’ we now show the name of the user and the name of the organization


The number of documents in human validation and accuracy are added to the overview page

You no longer need to open every specific project to know the accuracy of the model(s) and/or amount of documents waiting to be validated


OCR speed has been increased by a factor 2x

Start annotating almost right after you have uploaded the training documents


New pipeline for training incremental models

The amount of time needed to train an incremental model has been drastically improved


Various performance improvements, security improvement and bug fixes

We are constantly working on improving our performance and security


Release 1.9


Release 1.9

Analytics module gets major overhaul

Having detailed analytics is crucial for having a full overview of what is automated and where there are improvement points. In this release, we made them more granular and way faster so you can track performance over time.

  • – Key metrics added
  • – Selection of a predefined timespan is made possible
  • – Details of status(es) are shown per doctype(s)
  • – Graphs are made more precise with indication of amount
  • – Last snapshot is added

Enrichments: a powerful pipeline step for integrating custom logic

Enrichments are a powerful new step in the pipeline that can be used for integrating any type of custom logic, custom code, external data lookups or even custom Machine Learning models.

  • – New step ‘enrichments’ is added to the pipeline, with full configuration through the project settings.
  • – Human validation module support for enrichments is added and updated live with updates
  • – Enrichments that are part of a composite entity are supported.
  • – Example enrichments are added to our public GitHub repos.

Other new functionalities

Automatic deletion of production data is made available

Automatic deletion of production data with configurable retention period ensures you can comply with GDPR and privacy regulation by not keeping data longer than is strictly needed.

Out-of-the-box support for e-mails

By supporting Outlook and IMAP integration out of the box, getting started with Metamaze for mailroom automation or incoming documents is easier than ever. So no more manual monitoring or custom RPA bot is needed to automatically process everything from!
