Extract facts from text

Pull structured facts out of unstructured text — entities, sentiment, categories, key phrases, personal data to redact — as labels a system can act on, rather than answers a person reads. 68 products across 41 companies in the Ludbee catalogue carry this task — across 3 of the 4 layers of the stack: 29 Application, 5 Infrastructure, 7 Foundation Models.

Filter the whole directory by this job to sort and compare these products.

One product can run more than one way — the counts above are of records, not of products.

What this page does not claim

This list carries no score and no recommendation, and one order only: inside each layer, a company whose product for this task is marked AI feature — sold for another job, with AI as one function its own page names — comes after the rest, A–Z within each. The standing rule that applies to the whole directory applies here too: no payment changes a figure, a ranking or the order of any list, this one included. Nor can it yet say what governs any of these products once deployed — what data they can reach, what they are certified against, whether a vendor trains on what you send it. That field is defined in the ontology and is populated on none of the 3,888 products in the catalogue yet, so a page that leaned on it would be promising an answer the data cannot back. It will say so here the day that changes.
