Nanonets alternative: one API, accuracy in the contract.
Nanonets is a no-code workflow platform priced per block, with no accuracy guarantee. Invofox gives engineers one API — validated, structured JSON at 99.2% accuracy written into your SLA, and you only pay for the pages we get right.




Invofox as a Nanonets alternative
Nanonets gives you a flexible builder and plenty of knobs to turn. Teams look for a Nanonets alternative when they would rather not operate the model lifecycle themselves — the training runs, the retraining, the workflow upkeep that comes with it. Invofox is the managed version of the same outcome: define your schema, send documents, receive validated JSON, with no models of your own to keep alive. The accuracy target is contractual instead of something you measure and hope for.
When Invofox wins
- You do not want to own training and retraining — schema in, validated JSON out, nothing to maintain.
- You want predictable billing per page processed, not per block or per model kept running.
- You want accuracy in writing, with the pages we get wrong left off the invoice.
Everything Nanonets does — without the workflow builder or the per-block bill.
Nanonets is a capable platform if you want a no-code studio to build document workflows. Invofox is the developer-first API for teams that want validated, structured data from one endpoint — no blocks to wire up, no per-block math, and accuracy in the contract.
| Capability | Invofox | Nanonets |
|---|---|---|
| Built for | Developers — one API, structured JSON in, clean JSON out | Builders who want a no-code workflow studio plus an API |
| Setup | No training, no workflow to build — send a document, get schema-mapped JSON | Configure a block-based workflow; pre-trained or custom-trained models |
| Pricing | Pay only for the pages we extract correctly — flat and predictable, accuracy in the contract | Per-block credits — every step bills separately and each document runs a different number of blocks, so the real cost per document is hard to estimate; volume pricing is quote-based |
| Accuracy commitment | 99.2% accuracy written into your SLA, validated against ground truth | Strong benchmark accuracy, but no pay-for-accuracy guarantee |
| Built-in validation | Cross-field business rules (totals, tax, dates) before delivery | Validation built as blocks in the workflow you configure |
| Classifier & splitter | Auto-detects document types and splits multi-doc files in one call | Classification and splitting as separate workflow blocks |
| Async webhooks | Cloud-agnostic async API with standard HTTP webhooks | REST API with webhook support for async jobs |
| Zero-retention mode | Process, deliver, hard-delete — no copies, backups, or logs | Documents retained for review and workflow processing |
| On-prem / private cloud | Same API, deployed inside your perimeter | Docker / VPC / on-prem on the Enterprise plan |
| Compliance | SOC 2 Type II, ISO 27001, GDPR | SOC 2 Type II, ISO 27001, GDPR |

Accuracy in the contract.
Per-field accuracy targets are part of your SLA, validated against ground truth. If a page isn't extracted perfectly, you don't pay for it.

Every page where a mistake is reported through our API is credited back — no per-block math to forecast, no paying again to retry.
