Per Object
Pay for each labeled object, such as a box, polygon, keypoint, or cuboid. Cost scales directly with output.
Best for: well-defined tasks- Predictable cost per unit
- Ideal for detection and segmentation
- Volume-based rates
Transparent Data Annotation Pricing
Pay for the work you need, the way that suits your project. Every engagement starts with a free pilot, so you see the quality and the exact price before you commit.
Choose a Pricing Model
Three flexible models. You can switch between them as your project evolves.
Per Hour
Pay for annotator time when tasks vary, guidelines are still changing, or the work needs expert judgment.
Best for: evolving or complex tasks- Flexible scope
- Good for research and RLHF
- Transparent timesheets
Per Project
A fixed price agreed upfront for a defined dataset, taxonomy, and delivery date.
Best for: fixed scope and deadline- One price, no surprises
- Milestone-based delivery
- Dedicated project lead
What Affects Your Price
We look at these factors during the pilot to give you an exact quote.
Annotation Complexity
Simple tags cost less than dense polygons, pixel masks, or 3D cuboids.
Data Volume
Larger datasets unlock lower per-unit rates.
Quality Target
Higher accuracy thresholds need extra review stages.
Turnaround Time
Tight deadlines may require larger teams or extra shifts.
Domain Expertise
Medical, legal, or technical data may need trained specialists.
Tools and Formats
Working in your platform or a custom export schema can affect setup effort.
Included in Every Project
No hidden fees. These come as standard, whichever pricing model you choose.
- Dedicated project manager
- Multi-stage quality assurance

Pricing FAQs
Is the pilot really free?
Yes. We annotate a sample of your data at no cost so you can evaluate quality and speed, and we use it to give you an exact quote.
Do you have minimum order sizes?
No fixed minimum. We support small research datasets as well as large production volumes.
Can we change the pricing model later?
Yes. Many clients start per hour while guidelines evolve and switch to per-object pricing once the task is stable.
How do you invoice?
Invoices follow agreed milestones or monthly delivery, with a breakdown of volume, hours, and QA results.
