Models deployed for any workflow
Each processor is rigorously benchmarked and designed for easy composition in your workflows.
P · 01 Convert
Use Chandra to convert PDFs, spreadsheets, slides and more to structured markdown, html, and json. Includes word-level bounding boxes, redlines, and more.
P · 02 CustomizeCustomize processor output to your needs using natural language rules.
P · 03 ExtractFind key information using pre-defined extraction schemas.
P · 04 SegmentIdentify natural boundaries between documents that were originally combined into one file.
P · 05 EvalEvaluate the quality of output, using our criteria or your own rubrics for quality.

New primitives ship every quarter — see what's available now.
We're best in class.
Every number on this page cites a public dataset or our own runnable eval.
Compose. Deploy. Monitor.
One pipeline runtime — from a single API call to 100M pages a day.
Run our models anywhere.
Managed cloud, in your VPC, or fully air-gapped. We own the models — so you choose the network.
Monitor improvements and flag regressions.
Continuous evals against rubrics and a reference corpus — quality improves as we ship model updates, and any regression gets flagged.
Trusted in countless mission-critical workflows.
Same engine — different documents. From training corpora to clinical trials to claims forms, every vertical gets the same bbox-precise parsing.

"Working with Datalab has helped us move faster and solve complex edge cases with our documents. We need highly accurate document processing, and Datalab has been a key part of our data infrastructure. We're excited to continue to partner with Datalab."
— S., Member of Technical Staff, Frontier Lab
100M+ pages a day. Zero infrastructure.
Burst at scale on our GPUs. We allocate the workers, you pay per page processed. In production at the largest AI labs and Fortune 500 enterprises.
Open Source first.
Marker, Surya, and Chandra are our open source models — used by thousands of teams, 67.7k+ stars combined. Our managed platform handles scaling infrastructure, includes better proprietary models, and has enterprise-grade reliability.
Run it on our infrastructure. Or yours.
Because we own the models, you can run them anywhere — including networks that don't touch the internet.
