Nanonets requires you to train custom models for each document type and retrain them when formats change. If you process documents from dozens of vendors, that model maintenance never ends. We tested the top alternatives.
Lido is the best Nanonets alternative for teams that need accurate extraction across any document type without training custom models or annotating samples.
Nanonets requires model training for each document type. Lido reads any document layout on first upload. The core difference is whether you want to train AI models or just extract data.
Custom model training is a bottleneck. Nanonets' pre-trained models handle invoices and receipts, but every other document type requires training a custom model. That means collecting 50–100+ sample documents, manually annotating fields, training the model, evaluating results, and iterating. For teams processing diverse document types, the model training backlog never ends.
Email-based parsers like Mailparser face a similar scaling problem with per-sender templates. If that is part of your workflow, see our Mailparser alternative guide.
Accuracy drops on non-standard layouts. Nanonets works well on documents that match its pre-trained models. But when vendors send invoices in unusual layouts, scanned at odd angles, or with handwritten annotations, accuracy drops and requires manual correction. Teams processing documents from dozens of vendors find themselves in a constant cycle of model retraining.
Per-page pricing adds up at volume. At $0.30 per page, Nanonets looks affordable for small volumes. But a team processing 3,000 pages per month pays $900/month ($10,800/year). Lido's Scale plan covers 42,000 pages per year (3,500/month) for $7,000, with no per-page metering.
Model maintenance is ongoing. Nanonets models need retraining when document formats change. A vendor updates their invoice template, and your custom model breaks. For teams with dozens of vendor formats, this maintenance creates a persistent operational burden that never goes away.
These results come from teams that chose Lido's template-free approach over platforms that require per-document-type model training.
ACS Industries (Manufacturing, 1,000+ employees) processes 400 purchase orders per week across every format. With Lido: 30 hours saved per week on manual data entry, 99.5–100% accuracy on typed documents, and they avoided hiring an additional FTE.
ACS Industries "Thanks to Lido, we're processing ~400 weekly POs automatically with complete accuracy."
Soldier Field / ASM Global (Events, 1,000+ employees) handles 1,000 vendor invoices per month, each in a different format. What used to take 20 hours per week now takes 30 seconds per invoice. Setup took 15 minutes.
Soldier Field / ASM Global "What used to take us 20 hours each week now takes just 30 seconds per invoice."
Relay (Healthcare, 50–200 employees) processes 16,000+ Medicaid claims every 1–2 months, each running 700+ pages. With Lido: 100+ hours saved per week, 500% increase in team capacity, 98% reduction in human error.
Relay "Lido turned a process that used to take weeks or months into just hours."
TOK Commercial (Real Estate, 51–200 employees) manages 400 properties with 150 multi-page vendor documents monthly. Result: 85% increase in AP team capacity and one FTE hire avoided.
TOK Commercial "I explore a lot of solutions for our accounting needs, but none are as easy or effective as Lido."
ABBYY Vantage is the strongest enterprise alternative if you need on-premise deployment for data residency requirements. Decades of OCR expertise and a marketplace of pre-trained document skills. Starts at $8,000/year with multi-year contracts.
Docsumo is purpose-built for financial document types: invoices, bank statements, and tax forms. If your extraction needs are limited to these document types, Docsumo offers pre-built workflows with good accuracy. Custom pricing requires sales engagement.
Rossum is designed for large enterprises that need full AP automation with ERP orchestration. Pre-built integrations for SAP, Coupa, and Workday. Starts at $18,000/year with annual contracts and weeks-to-months onboarding. See our full best Rossum alternative guide for a detailed breakdown.
Step 1. Sign up for free at lido.app. No credit card required. You get 50 pages to test.
Step 2. Upload the documents that give Nanonets the most trouble. Not your cleanest digital invoices, but the scanned ones, the handwritten ones, the documents from the vendor that changes their format every quarter.
Step 3. Describe what to extract in plain English. No model training, no annotated samples, no configuration.
Step 4. Compare the results. Check accuracy on scanned inputs and handwritten text. Note how long setup took versus training a Nanonets model.
Most teams see structured output within 5 minutes of their first upload.
50 free pages. No credit card, no model training required.
Lido is the best Nanonets alternative for teams processing documents from multiple vendors in varied formats. Unlike Nanonets, Lido requires no model training or retraining-it extracts data from any document layout on the first upload. ACS Industries processes 400 purchase orders per week across every format with 99.5-100% accuracy and zero templates built.
The most common reasons are model retraining burden, poor accuracy on scanned and handwritten documents, and charges for failed extractions. A gas distribution company processing 27,000 documents per month said they "spend a ton of time retraining the models" after migrating to Nanonets. A government agency that signed a $30,000 contract called it "absolutely one of the worst."
Lido offers a free trial with 50 pages, no credit card required. Scale and enterprise plans are available for higher volumes.17/page). Nanonets enterprise contracts require custom quotes with per-use pricing. Lido includes 24-hour free reprocessing on every extraction.
No. Lido uses layout-agnostic AI that reads any document format without training or templates. You describe the fields you need in plain English and upload your documents. Extraction works on the first upload, including on formats the system has never seen before. There is no model training step, no retraining when vendors change formats, and no per-vendor configuration.
Yes. Lido uses AI vision models that understand document structure and context, not just character shapes. It handles scanned PDFs, faxed documents, photos of documents, and mixed printed and handwritten text. A government agency said Nanonets "bombed the demo" on their scanned documents before switching to Lido.
You adjust your extraction instructions and reprocess the document at no additional cost within 24 hours. This is one of the key differences from Nanonets, which charges for every extraction attempt including failures. With Lido, you only pay when the output is right.
