How OpenSite works

OpenSite turns ClinicalTrials.gov’s registry data into plain-English, evidence-cited answers about competing trials, site experience, and investigator track record — so clinical operations teams can make site-selection and recruitment-risk calls without waiting days for a manual feasibility pull.

How it works

1

Ask in plain English

Type a question about sites, principal investigators, competing trials, recruitment, or milestones — no SQL, no schema to learn.

2

OpenSite queries live registry data

It identifies the right tables and fields, checks the real stored values for phase and status before filtering, and runs a fresh, read-only query — every time, even on a follow-up.

3

You get a grounded answer

One direct sentence with the finding, a couple of decision-relevant caveats, and follow-up questions worth asking next — never an invented NCT ID, sponsor, or statistic.

4

Every claim ships with its evidence

A supporting-evidence table of the actual matching trials appears first, then collapses as the answer streams in — reopen it anytime, or download the full result set as a CSV.

02

Key features

Natural-language querying

Ask about sites, PIs, competing trials, or milestones the way you'd ask a colleague — OpenSite handles the registry query underneath.

Traceable evidence

Every answer is paired with the underlying rows, so a number is always a click away from the record it came from.

Live data on every turn

Follow-ups re-query current registry data rather than trusting the last answer — the registry moves, so the numbers keep up.

Table-first, exportable results

See the matching trials before the narrative, then export result sets larger than the on-screen preview to CSV.

PI & KOL identification

Surfaces which principal investigators — key opinion leaders — have run or recruited the most for a given indication.

Deliberately cautious language

Won't call a site or PI “best” without a defined metric, and flags when direct site or sponsor validation is still required.

03

Use cases by role

Clinical operations leaders, biotech sponsorsRecruitment risk

Size up the competition for patients before committing a lean team and a limited budget to a protocol, and watch for shifts in who else is chasing the same population.

Shortlist sites and investigators with real registered experience in an indication — and back the recommendation with evidence a sponsor can trust — before a single feasibility call is made.

Any of the abovesame question, phrased for a board update instead of a feasibility spreadsheet.

Every answer is grounded in that question’s live results. Conversation history carries intent, not data — so the numbers you see are never older than the question you just asked.
