Image Annotation
Boxes, masks, keypoints, polylines and cuboids under one evidence standard. Every geometry scored to IAA > 0.90 - disagreements adjudicated, not averaged.
Read MoreLabelFort is a secure, audit-ready, vendor-neutral data annotation platform for regulated teams. AI-assisted labeling is checked by trained human reviewers, with the evidence trail your Compliance, Legal, & Procurement teams already expect.

True 3D cuboids edited across synchronized multi-view scenes. Camera and LiDAR fused with shared scene context, exported native KITTI.

Native DICOM findings, measurements and landmarks - series-scoped. Clinician review with de-identification before a study is seen.
Read MoreSix governance pillars, engineered into the platform and the delivery model - so every dataset arrives with the evidence to defend it.
Immutable logs and chain-of-custody export. Every label, verifier action and configuration change is captured as evidence.
NDJSON audit export
Dual review with acceptance criteria; Inter-Annotator Agreement scored with Cohen’s kappa, IoU/F1 for geometric tasks.
Validated on your dataset
Aligned to SOC 2 Trust Services Criteria and engineered to satisfy HIPAA, GDPR and India’s DPDP Act. Stated only as precisely as evidenced.
Control mapping on request
Trained medical, financial and legal annotation teams as a risk control - not a crowd, not a freelance pool.
Medical · financial · legal
Weekly executive reporting for every week of the engagement, against a delivery SLA above 98%.

Audit-log coverage, by design
One governance model across every sector: domain-trained teams, agreement measured per cohort, and evidence built for the review each industry actually faces.
Data annotation cost depends on governance burden - data sensitivity, review depth, IAA threshold, evidence requirements and SLA - far more than on raw label volume. Regulated annotation is not priced per label: LabelFort prices engagements, and scopes a fixed $100 evidence-grade PoC (up to 1,000 annotations) before any production commitment.
Why we don't price per labelLabelFort is certified against ISO 27001:2022, aligned to SOC 2 Trust Services Criteria, and engineered to satisfy HIPAA, GDPR, and India’s Digital Personal Data Protection Act (DPDP). DPDP readiness is not an add-on - it inherits from the already-audited ISO baseline. A control-mapping document and our DPDP readiness report are available for Legal and Compliance review during intake.
Image (bounding boxes, circles, polygons and polylines, brush masks and SAM-assisted segmentation, keypoints and skeleton-based pose), video (shape and track modes with persistent object identities, keyframe interpolation and AI-assisted tracking), LiDAR and 3D point cloud (3D cuboids in synchronized multi-view), medical DICOM (structured findings, measurements and landmarks), text and structured data (classification, sentiment, intent and field extraction through configurable forms - CSV rows and PDF supported), audio (time-segment labeling with classes and attributes, verified transcription, speaker diarization), documents (VLM-assisted extraction via OCR/VQA pipelines), geospatial imagery, and RLHF/evaluation workflows. Platform-native exports: COCO (including RLE masks), YOLO, KITTI (2D and 3D), MOT17, labeled-image ZIP, Excel/CSV, and NDJSON audit logs; additional formats are delivered on request through the delivery pipeline.
Quality is measured with Inter-Annotator Agreement, scored using Cohen’s kappa - with IoU/F1 agreement for geometric tasks - against a threshold above 0.90, validated on your dataset during the PoC and tracked in delivery reporting. Every annotation action, review and configuration change is captured in an immutable audit trail and exports as a chain-of-custody record. Audit-log coverage is 100% by design.
LabelFort ships with dedicated role-based workspaces for Platform Admin, Admin, Operations Manager, Quality Manager, Annotator, Verifier, Auditor, and Client. Each role has its own routing, dashboards and navigation, and access checks are enforced on protected verifier and auditor surfaces.
Yes. LabelFort is tool-agnostic. Exports cover COCO (including RLE), YOLO, KITTI, MOT17, labeled-image ZIP, Excel/CSV and NDJSON audit logs - with additional formats on request - and delivery lands in S3, GCS or directly in your pipeline. File-dimension and tracking-attribute integrity are preserved end-to-end so annotations do not drift relative to the underlying media.
Compliance Review → evidence-grade PoC → governed pilot → procurement-ready scale. Pilot-to-production typically runs 30–45 days once the PoC evidence pack is signed off. We do not run open trials, we do not compete on price-per-label, and we do not enter engagements without a defined evidence output for Legal and Procurement review.
Yes. LabelFort supports structured RLHF preference collection, instruction tuning, evaluation rubrics, and red-team workflows - with the same IAA reporting, role-based QA and audit coverage as every other project type.
LabelFort is a product of Predusk Technology Pvt Ltd, an independent company with no hyperscaler or model-lab ownership stake. Your training data, audit logs and evidence packs do not route through, or back to, any competing foundation-model lab.
