Great question! We have this little tool that you can use to figure out how much time and money you can save.
On average, Parseur is considered up to 4x cheaper than the other AI data extraction tools and up to 97% cheaper than doing extraction by hand!
Nanonets
Nanonets is an intelligent document processing tool integrated with AI that processes documents such as driving licenses, IDs, or passports and invoices.
Nanonets provides automatic layout parsing and the ability to build your AI model as well.
Even if you're not a machine learning wizard, you can craft and customize models by training the AI.
Training your custom model is time consuming as you need a minimum of 10 annotated documents, and on the free plan, you're limited to creating just 5 labels (fields).
Docsumo
Docsumo comes with pre-trained models mostly for invoices and IDs, and you can also train a custom AI engine to extract the desired data.
The tool offers the power to train its AI model but buckle up for a steep learning curve, especially if you're not a technical person.
Rossum
Rossum focuses on the financial services industry and is the perfect companion for large account departments. Rossum flaunts an AI engine that's a quick learner, ready to be trained to parse different types of PDF files like a seasoned pro.
SMB players -- Rossum might not be the best fit as it is a product geared for large companies. Their pricing is not public which can be a red flag for some.
PDF.ai
PDF.ai superpower lies in providing a quick access to surface specific data from your documents, making life easier for anyone needing rapid information retrieval from PDF documents only.
However, there's a catch -- PDF.ai is a loner. You can only chat with your PDFs, you can't download the extracted data or seamlessly transfer it to another tool.
