Pricing
Pricing is based on the duration and terms of your contract with the vendor. This entitles you to a specified quantity of use for the contract duration. If you choose not to renew or replace your contract before it ends, access to these entitlements will expire.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimension | Description | Cost/12 months |
|---|---|---|
Growth tier | 1 workspace, 10 users, up to 250,000 labels, API access, Advanced Analytics, ML-assisted Labeling, Label Error Detection, Predictive Labeling, Data Programming, Datasaur Dinamic | $50,000.00 |
Dimensions summary
You buy the Growth tier as a single contract with a fixed set of capacity limits. This one bundle covers 1 workspace, up to 10 users, and up to 250,000 labels. Access to API, Advanced Analytics, ML-assisted Labeling, Label Error Detection, Predictive Labeling, Data Programming, and Datasaur Dinamic is included at this tier. Pricing does not scale by usage or add-ons. Instead, you commit to the tier and its capped quantities. If your team or label volume grows beyond these limits, you would move to a different arrangement.
Top-of-mind questions for buyers
A label is a single annotation you apply to a data point during a labeling task. Each tag on a piece of text counts separately. The Growth tier caps your total at 250,000 labels across your workspace. Automated and manually applied labels both count toward this figure.
The Growth tier is a fixed contract with capped quantities. It does not scale automatically or add overage charges. Once you reach 1 workspace, 10 users, or 250,000 labels, you cannot exceed those caps under this tier. You would move to a different arrangement with the vendor.
All listed capabilities come bundled in the single Growth tier contract at no extra charge. This includes API access, Advanced Analytics, ML-assisted Labeling, Label Error Detection, Predictive Labeling, Data Programming, and Datasaur Dinamic. There are no per-feature add-ons or usage-based charges layered on top.

Datasaur Makes Collaborative, ML-Assisted Labeling Fast and Flexible
Reviewed on Aug 13, 2026
Review provided by G2
What do you like best about the product?
What I like best about Datasaur is how it makes data labeling less painful and way more collaborative.
My top 3 things about Datasaur:
1. Collaboration is smooth
Multiple annotators can work on the same dataset, with disagreements tracked and resolved. No more messy spreadsheets or "which version is final" drama. It’s built for teams.
2. ML-assisted labeling
It uses models to suggest labels while you annotate. So you label 100 examples, it learns, and starts pre-labeling the next 1000. Cuts annotation time massively.
3. Works for all kinds of data
Text, images, documents, PDF contracts, NER, classification, QA pairs — you name it. The interface adapts and you can set up custom workflows + quality checks inside it.

What do you dislike about the product?
1. Pricing gets steep for big teams
For solo/small teams it’s okay. But once you scale to 10+ annotators + lots of documents, the cost jumps. Free tier is also pretty limited.
2. Learning curve for complex workflows
Basic labeling is easy. But if you want custom ontologies, multi-stage reviews, agreement metrics, and automation rules — setup takes time. New users often get lost in all the settings.
3. UI can feel heavy sometimes
When datasets get huge or you’re labeling 50-page PDFs, the platform can lag. And searching/filtering through thousands of labeled items isn’t as fast as I’d like.

What problems is the product solving and how is that benefiting you?
Problem: Before, labeling data for AI meant spreadsheets, Google Docs, or building your own tool. 1 person labels 200 examples/day, and quality is all over the place.
How Datasaur helps: ML-assisted labeling. You label 200, the model learns, and it pre-labels the next 2000. My speed goes up 5x-10x.
Problem: 5 people labeling same dataset = different formats, disagreements, no tracking who did what.
How Datasaur helps: Built-in collaboration + disagreement resolution + agreement scores. Project manager can assign, review, and audit everything

Datasaur Makes Data Labeling Organized, Efficient, and Team-Friendly
Reviewed on Aug 13, 2026
Review provided by G2
What do you like best about the product?
What I like most about Datasaur is that it makes the data labeling and annotation process much more organized and efficient. The interface is straightforward, and it is easy to review, label, and manage large amounts of data without making the workflow unnecessarily complicated. I also like the collaboration features, which make it easier for teams to work consistently on annotation projects.
What do you dislike about the product?
The main thing I dislike about Datasaur is that some advanced features can take a little time to understand, especially for new users. The interface can also feel slightly overwhelming when working with complex annotation projects or large datasets. A more streamlined experience for beginners and clearer guidance for advanced features would make it easier to get started.
What problems is the product solving and how is that benefiting you?
Datasaur simplifies the process of labeling and organizing large datasets, which can otherwise be time-consuming and difficult to manage manually. It provides a structured workspace for annotation, review, and collaboration, helping reduce repetitive work and maintain consistency across projects. This makes the overall data preparation process faster and helps me work more efficiently with datasets used for AI and machine learning.

What do you like best about the product?
I like Datasaur the most because it makes data labeling and annotation simple and efficient. The interface is intuitive, and the tools for managing, reviewing, and organizing datasets help streamline the process and speed up AI and machine-learning workflows.
What do you dislike about the product?
One thing I dislike about Datasaur is that some of the more advanced features can take a while to understand, especially for new users. I also think the platform could improve its customization options and make certain workflows feel more intuitive and straightforward.
What problems is the product solving and how is that benefiting you?
Datasaur helps me tackle the challenge of **managing and labeling large amounts of data for AI and machine-learning projects**. It streamlines annotation and keeps data organized, making the overall workflow more efficient. As a result, I save time, maintain better data quality, and can prepare more reliable datasets for training and evaluating AI models.
