What the service does

From raw input to reviewable structure.

Build a repeatable review loop for label consistency and acceptance decisions. Labels and instructions are calibrated with your team on a small pilot before larger batches begin.

Typical tasks

  • Sampling plan
  • Peer review
  • Disagreement analysis
  • Acceptance audits
Typical input

What you provide.

Annotated records, guidelines and project-specific thresholds.

Typical output

What you receive.

Audit results, corrections and disagreement log.

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.

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

Human-in-the-loop quality

Quality is a process. Not a percentage on a page.

Acceptance thresholds, review methods and sampling are agreed for each project. Calibration happens before volume.

LEVEL 1

Annotator review

LEVEL 2

Peer review

LEVEL 3

Quality reviewer

LEVEL 4

LEVEL 5

Client feedback loop

We document uncertainty and disagreement, revise guidelines with your team and keep an audit trail of corrections. Specialist medical, legal or financial review is available subject to project requirements and qualified reviewer availability.

  • Pilot, batch or milestone-based delivery
  • Versioned exports and a documented handover
Project questions

Scope the work with confidence.

What do we need to provide?

Annotated records, guidelines and project-specific thresholds. 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 CSV, JSON, Report; exact schemas, tools, volumes and timelines are agreed before starting.
