A Computer-Use-Agent that runs legacy software like a human
Coasty is a computer use agent that operates real desktop software end to end. Started with healthcare prior auth, automating payer portals and legacy EHRs, and data removal for data privacy but now we're expanding into insurance and tax & accounting. Coasty does that work autonomously, with human takeover and full audit trails. Independently verified at 82.81% on OSWorld Verified (359 tasks), near the top of the leaderboard. No APIs required. If software has a screen, Coasty can run it.
Hey everyone, I'm Prateek, co-founder of Coasty.
We didn't start here. Our first product was an LLM aggregation tool. When we analyzed 14,000+ agent interaction logs, we noticed the real bottleneck wasn't the models. It was operating legacy desktop software end to end. Payer portals, EHRs, freight TMS systems. Software with no API, just a screen.
So we built an agent that uses the computer the way a person does. It clicks, types, reads screens, and knows when to hand off to a human. We scored 82.81% on OSWorld Verified (359 tasks), independently evaluated, which puts us near the top of the leaderboard.
Happy to answer anything about how the agent works, where it fails, and what it took to get it reliable enough for regulated work.
