Who should use the Annotate training data workflow?
Teams or solo builders working on development tasks who want a repeatable process instead of one-off tool experiments.

Step map
Instead of relying on a single generic AI model, this pipeline connects specialized tools to maximize quality. First, you'll use Notion AI 3.0 to a validated annotation guideline document ready for annotators or tools. Then, you pass the output to Modal AI to clean, split dataset loaded into annotation platform with no duplicates. Then, you pass the output to Supervise.ly to refined annotation guidelines with high agreement (kappa ≥ 0.7) on pilot data. Then, you pass the output to Lightly to maximized annotation efficiency with model-guided sampling (optional). Then, you pass the output to Prodigy to complete annotated training set with verified quality (agreement ≥ 0.8). Finally, Anaconda is used to validated, export-ready annotated dataset with a quality report.
Define annotation schema and guidelines
A validated annotation guideline document ready for annotators or tools.
Prepare raw data and split sets
Clean, split dataset loaded into annotation platform with no duplicates.
Perform initial annotation round (pilot)
Refined annotation guidelines with high agreement (kappa ≥ 0.7) on pilot data.
Scale annotation with active learning (optional)
Maximized annotation efficiency with model-guided sampling (optional).
Full-scale annotation and quality control
Complete annotated training set with verified quality (agreement ≥ 0.8).
Export and validate final annotations
Validated, export-ready annotated dataset with a quality report.
Start by clarifying the task (classification, extraction, etc.) and the label set. Write a concise annotation guideline document with examples and edge-case rules. This ensures consistency across annotators and tools.
Why Notion AI 3.0: Notion AI 3.0 provides a collaborative document editor with AI-assisted writing and structuring, ideal for defining annotation schemas and guidelines.
Gather the unlabeled dataset, clean it (remove duplicates, fix formatting), and split into training, validation, and test sets. This prevents data leakage and ensures evaluation integrity.
Why Modal AI: Modal AI supports running batch data processing at scale, which can handle Python/pandas scripts for data preparation and splitting.
Annotate a small batch (e.g., 50-100 items) to test the schema and guideline clarity. Review disagreements and refine the guidelines before scaling. This catches ambiguous labels early.
Why Supervise.ly: Supervise.ly supports multi-annotator image/video annotation and dataset management, suitable for a pilot annotation round.
If using a model-in-the-loop, train a preliminary model on the pilot annotations, then use it to suggest uncertain samples for annotation. This reduces total annotation effort by focusing on informative examples.
Why Lightly: Lightly specializes in active learning selection and edge case detection, directly supporting active learning workflows.
Annotate the entire training set following the finalized guidelines. Implement ongoing quality checks by randomly re-annotating 10% of items and measuring agreement. Flag and correct low-confidence annotations.
Why Prodigy: Prodigy provides a QC dashboard and supports full-scale annotation with active learning and review workflows.
Export the annotated dataset in the required format (e.g., JSONL, COCO, CSV). Run validation checks for missing labels, format errors, and class balance. Generate a summary report for downstream training.
Why Anaconda: Anaconda provides environment isolation and package management for running Python validation scripts and managing dependencies.
§ Before you start
Teams or solo builders working on development tasks who want a repeatable process instead of one-off tool experiments.
No. Start with the top pick for each step, then replace tools only if they do not fit your pricing, compliance, or output needs.
Open the mapped task page and compare top options side by side. Prioritize output quality, integration fit, and predictable cost before scaling.
