"LLMWhisperer Nails OCR for Scanned PDFs with Clean, Structured Output"

4/5

What do you like best about Unstract LLMWhisperer?

The best thing about LLMWhisperer is that it handles scanned and complex PDFs really well. We get old faxed documents and poor quality scans but it extracts clean text without breaking. The layout and structure stays intact which is crucial for us when we extract data from forms and invoices. It also gives output in multiple formats like JSON and Markdown which makes integration easy with our existing systems. The OCR is accurate and the processing speed is good enough for production use.

The AI accuracy is impressive on complex and handwritten documents. Price is on higher side but the value we get justifies it because we save so much manual work. Review collected by and hosted on G2.com.

What do you dislike about Unstract LLMWhisperer?

One major issue I found is with their pricing and tier structure because their 100 calls per day free quota is not available once you move to the paid APIs. Also the biggest red flag for us was data security because they do not secure files or guarantee privacy in the free tier which makes it impossible to test with real company documents. Because of this we had to be very careful with what we uploaded during our initial testing phase and it forced us to look at paid tiers earlier than we wanted.

What problems is Unstract LLMWhisperer solving and how is that benefiting you?

We needed it to extract structured text to feed LLM models for more accuracy in data extraction. Now We upload a document and it automatically extracts all the data in the format we need. It handles scanned PDFs really well which was a big pain point for us before. This saved us so much time and reduced manual errors significantly.

The best thing is that it handle any kind of pdf in any dimensions and handwritten languages like Spanish and English

The accuracy is really good so we don't need to manually verify everything. Overall it made our document processing workflow much faster and more reliable Review collected by and hosted on G2.com.
