Fast Data Labeling

Label your data 1000× faster.

We turn raw text, images, tables, time-series, and audio into training-ready labeled datasets in hours, not months. Foundation-model pre-labeling, active learning, and expert human verification — assembled into a single rapid pipeline.

From six months of manual labeling to a labeled dataset by Friday.

Why teams call us

The bottleneck is not the model. It is the labels.

Modern training jobs starve while teams wait weeks for vendors to label what a foundation model can pre-label in seconds. Here is the gap on a 100,000-item job:

Traditional vendor 14d 06h 12m
142 / 100,000 ~1 label / 12 sec · queue blocked
Tabularis pipeline 00:00:07
100,000 / 100,000 ~14,250 labels / sec · review queue 4.2%

Every data type

One pipeline. Five modalities. Same fast loop.

The core loop

Active learning, not brute-force annotation.

Models predict. Uncertainty is scored. Humans only see what they need to see. Every reviewed item flows back into the model — making the next batch easier.

  1. Predict. Foundation models, fine-tuned classifiers, and rule layers all label the same item in parallel.
  2. Score uncertainty. We measure model disagreement, calibrated confidence, and class-specific thresholds.
  3. Route to humans. Only ambiguous, rare, or low-confidence items reach the review UI — the rest auto-confirm.
  4. Retrain & iterate. Every reviewed correction feeds the next pass. The hard slice gets smaller every cycle.

The full pipeline

Six steps. One contract. Repeatable forever.

We do not run a one-off labeling project. We hand you a re-runnable pipeline that turns any new batch of raw data into labeled training data on demand.

  1. 01

    Define labels & acceptance specs

    We codify your taxonomy, edge cases, and quality bar into a machine-readable spec. Disagreement rules, gold-standard examples, and confidence thresholds are decided up-front so the pipeline never drifts.

    Connect raw data, redact PII inline

    Stream from S3, GCS, Azure, BigQuery, Postgres, Kafka, or local mounts. Sensitive fields can be redacted, hashed, or tokenized before any model sees them — GDPR by construction.

    Pre-label with foundation models

    Zero-shot, few-shot, or fine-tuned models generate first-pass labels at >1,000 items per second. Multiple models vote in parallel, producing both a label and a calibrated confidence score for every item.

    Score uncertainty, route hard cases

    Active learning ranks every prediction by model disagreement and uncertainty. Confident cases pass through; hard, ambiguous, or rare items bubble to a focused human review queue — typically less than 5% of the data.

    Human-in-the-loop review

    Domain experts review only the slice that matters in a fast, focused UI: keyboard-first, hot-key driven, with reference examples and disagreement context. Reviewer agreement is measured continuously.

    Consensus, audits & ship

    Multi-model consensus, gold-standard spot checks, and reviewer agreement merge into a single quality score. Final labels export as JSON, COCO, CSV, Parquet, or pushed back into your training pipeline.

Who needs this now

If your training run is waiting on labels — start here.

Computer vision teams

Pre-drawn bounding boxes, segmentation masks, keypoints, and classification — your annotators only touch the hard frames.

NLP & document AI teams

Entities, intents, sentiment, contract clauses, and ICD codes labeled across 20+ languages with consistent taxonomies.

RLHF & instruction-tuning teams

Preference pairs, response ratings, safety judgments, and reasoning traces curated at the scale modern post-training needs.

Regulated industries

Medical, financial, and legal labeling on-premise. No PHI, PII, or proprietary data leaves your infrastructure.

Research & evaluation teams

Build evaluation sets, benchmarks, and gold-standard datasets in days instead of months. Versioned and reproducible.

ML platform teams

Plug a labeling layer into your existing stack — APIs, S3 watchers, webhooks, and Airflow / Dagster integrations.

Questions teams ask first

Practical answers before we touch your data.

What data types can Tabularis label?

We support text, documents, images, tabular records, time-series, audio, and RLHF-style preference data. The pipeline is adapted to your taxonomy, export format, and quality requirements.

How do you keep quality high when labeling quickly?

Foundation models create first-pass labels, active learning routes uncertain items to reviewers, and agreement checks catch drift. Humans focus on the ambiguous slice instead of relabeling everything manually.

Can labeling run inside our own infrastructure?

Yes. For sensitive datasets, the workflow can run in your VPC or on-premise environment so regulated or proprietary data does not need to leave your control.

What do we receive at the end of a labeling project?

You receive versioned labels in practical training formats such as JSON, CSV, COCO, or Parquet, plus the repeatable pipeline so new batches can be processed again without starting from scratch.

Next step

Send us a sample. We label it on the call.

Bring 100 raw items — text, images, rows, signals, audio — and we will pre-label them live, walk through the uncertainty queue, and quote a real plan for the full dataset before the meeting ends.
