Chat
A conversational search at /chat. Tell it what you're looking for in plain language — typos, brand names, and informal terms are fine. It corrects, asks if it needs to, and shows you matching trials.
Three layout variants
Pick whichever feels natural — they all share the same agent and produce the same trial set. Switch any time via the Layout toggle in the header.
Inline — /chat/inline
Trial cards render inside the conversation. Most chat-native feel. Best for quick questions and small result sets.

Split — /chat/split
Two panes: chat on the left, dedicated trial results panel on the right that updates live. Best when you want to browse many results while keeping the conversation visible.

Guided — /chat/guided
Chat-only, no inline trial cards. Once the agent has enough to search, it shows a filter summary card with an Open in Advanced Search → button. Best when you want a clean intake → handoff flow.

What to type
Anything natural works. The agent will resolve:
- Typos:
pembrolizamab→ pembrolizumab - Brand names:
Keytruda→ pembrolizumab;Tagrisso→ osimertinib - Umbrella terms:
blood cancer→ leukemia + lymphoma + myeloma;triple neg→ triple_negative - Aliases:
Bombay→ Mumbai;Bangalore↔ Bengaluru - Acronyms:
TNBC,NSCLC,AML,DLBCL
Quick-reply chips
When the agent needs to disambiguate, it shows a question with clickable options:

Click a chip and it becomes your next message. Faster than re-typing.
Country priority + loose matches in chat
The same bucket model from Advanced Search applies — trials in your preferred countries first, then the rest, then a Broader / loose matches tail when you scroll past the strict cards.
Safety
The agent does not give medical advice and won't tell you whether you qualify. It surfaces trials; eligibility judgment is for the trial team and your oncologist. A persistent banner at the top of every chat page repeats this.
