The platform pairs that with human-in-the-loop review so operators can correct outputs and reduce downstream post-processing. Nanonets also supports batch document processing and form-like extraction from multi-page PDFs, which is valuable for high-volume invoice and contract work.
A key tradeoff is that model quality depends on the quality and coverage of labeled examples, so early iterations can require active learning-style annotation cycles. Nanonets fits best when teams need to move from manual review to semi-automated extraction for semi-structured documents that vary by source or template.
- +Confidence-scored fields make exception handling measurable
- +Human-in-the-loop review closes the loop on model errors
- +API-first extraction results return as structured JSON

How to Choose the Right Information Extraction Software
We see the real separation in information extraction software come from how you define what to pull, and how that extraction becomes usable downstream. Pay close attention to the schema control and integration depth because demos often look similar until you test the full workflow.
Extraction scope and targeting rules
Why it matters
Extraction scope and targeting rules determine whether the tool pulls the right fields from messy inputs or drifts into irrelevant text. This matters because teams usually need repeatable pulls, not one-off results.
How to check
Use a sample set with at least two document types and ask for field-level targeting (per document type or section). Run the same inputs twice and compare whether the pulled items stay consistent when the document order changes.
Schema control for extracted outputs
Why it matters
Schema control shows whether extracted results match your data model instead of forcing post-processing. When extraction outputs are stable, downstream automation and auditing are easier.
How to check
Ask the demo to show how they map extracted fields into a defined schema (including required vs optional fields). Then request one “variant” input (missing a field) and confirm what the output contains and how it signals absence.
Automation and API surface for actions
Why it matters
Automation and API surface decides whether extraction just ends at viewing, or can trigger updates in your systems. Deep control reduces manual handling when volume or turnaround time increases.
How to check
Request a walkthrough of at least two actions after extraction (for example: create/update a record and write a status). Verify what endpoints or automation hooks are available and whether you can pass identifiers from your system into the job.
Confidence reporting and exception handling
Why it matters
Confidence reporting and exception handling affects operational trust when the input quality varies. You need a practical way to isolate low-quality extractions without derailing the entire batch.
How to check
Provide an input that is ambiguous and ask the tool to show how it reports uncertainty. Confirm whether it can route exceptions to a separate review queue or flag them in output so you can filter reliably.
Throughput workflow and batch controls
Why it matters
Throughput workflow and batch controls determine how the tool behaves in real operations, especially for mixed document loads. Good controls help you avoid repeated reprocessing and simplify reruns.
How to check
Ask for a demo workflow that handles multiple files with different formats or sizes. Then test reruns: change only one input and verify whether results can be regenerated without redoing everything.
Admin governance and RBAC controls
Why it matters
Admin governance and RBAC controls matter when more than one team touches configurations and outputs. They also support accountability through audit logs when you need to trace changes.
How to check
Request role separation for at least two personas (config editor vs viewer). Check whether there are audit logs or history for extraction configuration changes and whether permissions apply to both jobs and results.
Red flags
- The tool returns free-form text instead of a stable schema your team can use
- Extraction varies wildly on the same input after minor formatting changes
- The automation path stops at a UI with no practical API or action hooks
Fit by situation
- If you regularly process multiple document types, prioritize extraction scope and targeting rules.
- If your downstream systems require consistent fields, prioritize schema control for extracted outputs.
- If extraction must trigger updates in existing workflows, prioritize automation and API surface for actions.
