Key Feature

Multi-Model Verification

Run the same check independently with multiple AI models and compare their level of agreement. Disagreement flags results for closer review; agreement does not guarantee accuracy.

  • Cross-validate results with multiple AI providers
  • See agreement scores for each verification
  • Compare independent results for closer review
  • Keep a person responsible for final decisions

Illustrative example — not a measured accuracy score.

Reusable Checklists

Define your verification criteria once, then reuse them on supported documents. Build a library of custom checklists tailored to your specific needs.

Full Transparency

Inspect structured results, model-provided explanations and available evidence. These explanations help you review outputs; they are not a complete record of a model's internal reasoning.

Verification Agents

Add independent AI verifiers that run checks without seeing the original analysis. Compare outputs to identify disagreements that need human review.

Automated Document Analysis in 4 Steps

Transparent Results

Review reports, extracted data and optional verifier agreement against the source documents.

Frequently Asked Questions

CheckIt.so analyzes documents against reusable AI checklists. You define the checks, upload documents, and review structured results with model-provided explanations.

CheckIt.so processes PDF, DOCX, TXT, and images (PNG, JPG, JPEG, GIF, BMP and WEBP). Convert legacy DOC files to DOCX or PDF first; legacy DOC parsing is not supported. You can submit individual files or batches.

Optional verification agents run the same check independently without seeing the primary analysis. You can choose different models and compare their results with agreement scores. Agreement does not prove that a result is correct.

Processing uses account credits; usage depends on the document, selected models and checks, including optional verifiers. Additional credits cost USD $9.99 per 100-credit bundle, with 1 to 50 bundles per purchase. Free signup credits are not unlimited free usage.

Create a free account to receive 1,000 credits; no payment card is required to sign up. Verify your email, sign in, create or import a checklist, and upload supported documents. Buy more credits when needed.

AI results can be wrong. Model agreement is not a guarantee of accuracy. Review the source documents and results before making legal, compliance, hiring or other consequential decisions. Document size, readability and model limits can affect processing; long PDFs may be truncated.
