about your Data
Our platform adapts to pretty much every text-related input, wether it is an email, PDF document or a Google Review. It nativaly embeds Optical Caracter Recognition (OCR) and parses tables.
1
Highlight and fine-tune
in a matter of seconds
Get started right away by creating a specific pipeline and choosing your analyses from among a baker’s dozen (i.e., spell check, sentiment analysis, IA entity recognition and more) Teach Lettria what you want to extract.

2

You’re not alone
Create a work group (or several) and invite your collaborators, so you can build dictionaries and annotate data together.
We also have a little gift for you: 750,000 pre-categorized words to help you kickstart your project. You’re welcome.
3
Start processing
& monitor quality
That’s pretty much it. You’re ready to go.
Our language processing toolkit is available as a single easy-to-use API and a no-code platform. Collect your results and monitor.

Lettria allows you to upload your documents and tag the key pieces of information you want to extract.
Our active learning models will then learn from your examples to accurately extract targeted data from all your documents.

Edit your very own knowledge ontology
in a few clicks
Ontology is a fancy way to refer to a set of concepts related to each other.
In other words, just tell us what you precisely want to extract in your documents.

Each property should be linked to at least one pattern. Each pattern is a sequence of elements to be found in the document.
