Why do you need a PDF parser?
A PDF parser is a software that extracts data from PDFs and parses it into a structured format. This makes it easier for businesses to analyze the data, edit it, and export it to other formats.
With a PDF parsing tool, you can easily extract text and images from PDF documents and data from tables.
A PDF parser helps to automate manual data entry processes and enables businesses to be more efficient in their workflows.
How does Nanonets work?
Founded in 2017 and based in San Francisco, Nanonets is an intelligent document processing platform that extracts and processes information using AI and OCR. It’s designed to reduce manual data entry and help teams automate routine document workflows.
Automatic layout parsing
You can either upload your PDF directly to the Nanonets app, send it via email or copy it from Google Drive. Let's say you want to capture invoice data, click on "invoices" and drag & drop the invoice and Nanonets will extract the data automatically. Their new interface is a bit confusing for beginners.
You can only parse 500 pages on the free plan.
Nanonets AI
Nanonets provides a trainable AI workflow that lets teams improve extraction performance by correcting outputs and re-training models. Model training and model-selection controls are gated by subscription model selection, and custom training is not available on the free plan and requires an upgrade.
You can choose between three model tiers, each balancing speed, cost, and accuracy for different document types and production needs:
Nanonets Nano — Balanced speed & accuracy
Designed for semi-structured, single-page documents with moderate layout variance (typical examples: invoices, purchase orders). Use Nano when you want fast inference with good baseline accuracy and minimal latency. Good first step for teams that need reliable field extraction without heavy training overhead.
Nanonets Mini — High accuracy with reasonable latency
Optimized for more complex layouts and lower-quality inputs (noisy scans, variable templates, multi-page documents). Mini is the recommended tier when the document structure varies or when table/line-item extraction must be reliable (typical examples: bank statements, multi-page invoices). Expect longer inference times than Nano, but improved extraction fidelity for edge cases.
Nanonets Pro — Best-in-class accuracy (higher cost, higher latency)
Intended for mission-critical documents where precision is non-negotiable. Pro is tuned to maximize accuracy for difficult formats and edge cases (e.g., financial statements, regulatory forms, medical reports). This tier is the slowest and most expensive; choose it when manual review is unacceptable and model precision must be maximized.
Other features of Nanonets
- Automated Workflows: You can build end-to-end document processing pipelines directly inside the platform, from data capture to validation and export.
- Multilingual OCR: Nanonets supports data extraction in 40+ languages, including non-Latin scripts such as Arabic, Chinese, and Tamil.
- Advanced AI OCR Features:
- Newer models support:
- Signature and QR code detection
- Watermark extraction
- Improved table parsing and layout understanding
- Newer models support:
- Customizable Field Capture: Users can define the data fields they want to extract and refine results as needed through model training.
- Integration Options: Nanonets offers webhooks, APIs, and third-party integrations for exporting structured data to other systems.
Pricing
Nanonets' pricing is complex and unclear.
- Pay as you go plan : Provides $200 of credits
- Credits Accelerate : Volume-based pricing and premium features
- Enterprise: Custom pricing for large processing volume
What you need to know before choosing an AI OCR tool
AI OCR is great when its machine learning model is trained well and does exactly what you want. You upload a new document that the tool has never seen before, and a few minutes later, you get your data with all data points included and accurately captured. It's a bit like magic!
Many AI OCR tools recommend that you implement a "human-in-the-loop" process to make sure the extracted data is correct. This, of course, will add to the running costs of an already expensive tool.
The most common issue with AI OCR-based tools like Nanonets is that they will sometimes miss some data points in documents. When that happens, you will usually be able to correct the data manually. But if you want to make sure the issue doesn't reappear, you will need to retrain your model, which can take hours. And after that, you cannot even be certain your model will work better for a similar document.
Lastly, in the case of Nanonets, as far as we understand, you are not able to improve and retrain their base models. If you want to customize a model, you will need to create a blank custom model and train it from scratch, uploading and annotating dozens of samples.
At Parseur, we decided to build a tool that is easy to understand, fast to troubleshoot, and reliable once set up. Our AI parser doesn't require extensive training and is a fast learner. It extracts data instantly without human intervention as it has already been trained for data extraction.
We also provide the option to create custom templates using Zonal OCR and Dynamic OCR. If your documents have the same layouts, then you can opt for this option.
Parseur: Nanonets alternative in 2026
Parseur is a PDF parser with a fast and cutting-edge AI and machine learning algorithms for data extraction. Parseur also doubles as an email parsing tool where it can extract data from emails effectively.
With Parseur's free plan, you have access to all the features for a limited amount of documents.
Robust AI Engine with Flexibility
Unlike black-box solutions, our platform offers transparency and control, allowing you to understand how your data is processed. You can leverage the AI's capabilities for automatic parsing while still having the option to fine-tune the process to suit specific requirements.
Table parsing
Parseur reliably extracts table data from PDFs in a few clicks. It's done leveraging Dynamic OCR by simply creating a table field and assigning start and end labels to tell the tool where the table starts and stops.
Integrates with thousands of applications and APIs
Parseur has native integrations with Zapier, Make (formerly Integromat), Power Automate where you can send the extracted data to any application of your choice.
You can also create custom Webhooks and send the data back to your servers. For example, you can use it as a DoorDash API for your food delivery process.
Other features of Parseur
- Documents supported: Microsoft Word, Email, Spreadsheet, HTML, Text, RTF
- Data normalization: Numbers, dates or addresses are normalized in consistent formats.
- Advanced post processing (available on the pro plan only): You can write advanced code using Python for further data manipulations.
- Web page parsing: Parseur can extract data from a webpage URL.
- Notifications: You can be notified by email or webhook whenever a document fails to parse.
- Data retention policy: For privacy purposes, you can set a policy that will delete all the documents after a specific time.
- GDPR compliant: Parseur is fully compliant with GDPR and uses the best security practices.
- Reliable API integration: Use Parseur’s REST API to upload documents, retrieve structured data, automate workflows, and integrate directly with your CRM, ERP, accounting tools, or custom internal systems.
Affordable Pricing
Parseur’s pricing is designed to be simple, transparent, and flexible, so you can get powerful document processing without breaking your budget.
- Free Plan: Process up to 20 pages/month for free. You still get unlimited mailboxes and unlimited fields.
- Base Tier: Starts at $39/month (or equivalent in your currency) for up to 3,000 pages/month.
- Scale Tier: For high-volume usage up to 1 million pages/month, with advanced features like post-processing and team accounts.
- Enterprise: Custom plans are available for very large or specialized workflows.
Why Parseur Offers Better Value
- Unlimited mailboxes: Use as many mailboxes as you need on any paid plan, unlike some competitors.
- Lower cost per page as you scale: Higher-volume plans offer lower per-document costs.
- No hidden fees: Everything’s included from AI parsing, exports, and data extraction.
Prices fall sharply as your monthly volume increases, we publish per-credit pricing on the pricing page and surface exact rates in the app so you can model costs precisely. Prices get heavily discounted as your volume grows.
I'm kicking myself on how I didn't find Parseur first before I tried all these other platforms, because it was able to perform where no other app could and the user interface is the cleanest out of all of them.
