What Needles and Trialworks firms get with Neos

Everything you built your workflow around

One system, intake to settlement

Cases, documents, medical records, and settlement figures live in one place instead of split across add-ons and exports.

Embedded intelligence

NeosAI drafts chronologies, summaries, and demands directly from the case record. Neither Needles nor Trialworks was built with this in mind.

Still built by the same team

Your firm's institutional knowledge of PI workflow carries forward. This isn't a switch to a generalist platform, it's the same PI focus, modernized.
