Demo / Illustrative example

Make the output tangible.

This synthetic example shows the structure of a record. It is not a client dataset or a claim of project performance.

Labels with a clear purpose.

Text regions is defined in the project guidelines. Ambiguous examples are flagged for review instead of silently forced into a category.

Project questions

Scope the work with confidence.

What do we need to provide?

Document scans or PDFs with an extraction schema. You also provide lawful access and usage rights, security requirements, acceptance criteria and a project owner who can resolve ambiguities.

How is annotation quality measured?

We agree a task-specific rubric, calibration pilot and sampling plan. Peer review, quality review and client feedback inform acceptance. No universal accuracy percentage is advertised.

Can you handle specialist subject matter?

Specialist medical, legal, financial or expert RLHF work is available subject to project requirements and qualified reviewer availability. Suitability is confirmed during scoping.

What delivery options are available?

Pilot batches, milestone-based deliveries or a scoped recurring workflow. Typical formats include JSON, CSV, ALTO XML; exact schemas, tools, volumes and timelines are agreed before starting.
