Why teams choose it

📎

Long-context analysis

Helps teams summarize, compare, and extract insights from long documents without losing important nuance.

📊

Document-heavy workflows

Useful where teams ingest PDFs, slides, audio, or long threads and need repeatable extraction—not one-off prompting.

✍️

Cost-efficient routing
