Domain adaptation prompt builder
A prompt that works for a general audience often falls flat in a specialized industry. A healthcare answer needs clinical caution and the right terminology; a finance answer needs regulatory awareness; a legal answer needs jurisdiction-specific framing. The domain adaptation prompt builder takes a generic prompt and stamps it for a target vertical — injecting the vocabulary, audience assumptions, regulatory context, and output conventions that domain expects. It runs entirely in your browser.
How it works
You paste a generic prompt, pick a target domain (or type your own), optionally add regulatory context, and describe the audience. The builder then wraps your prompt with:
- A domain framing line that sets the model’s persona and the vocabulary register for that vertical.
- Audience calibration so the depth and jargon match the reader’s expertise.
- A regulatory reminder that names the relevant rules and tells the model to flag where professional review is required.
- Output conventions typical of the domain — citations and disclaimers for medical, defined terms for legal, figures and assumptions for finance.
What the output looks like
Starting from a generic prompt like:
Explain the main risks involved in this process.
The builder for a healthcare, clinician audience, with HIPAA and FDA framing produces something like:
You are a clinical subject-matter expert writing for board-certified physicians. Use standard medical terminology appropriate for a clinical audience, cite relevant clinical evidence where appropriate, and include a note wherever professional clinical judgement is required. Adhere to HIPAA privacy principles when discussing patient information, and reference applicable FDA guidance where relevant. Do not overstate certainty; flag areas of clinical controversy or evolving guidance explicitly.

The same source prompt adapted for a financial services, retail investor audience, MiFID II context becomes:
You are a financial expert writing for retail investors with no professional finance background. Use plain language, define any technical terms you introduce, and flag any area where individual circumstances or professional advice are relevant. Be aware of MiFID II suitability and disclosure requirements; where you mention a product or strategy, note that suitability depends on individual risk profile.
Explain the main risks involved in this process.
When to use domain adaptation
- Scaling one prompt across multiple verticals — maintain a single source prompt and stamp it per industry rather than writing a new one each time.
- Ensuring regulatory vocabulary appears — regulated sectors have specific terms that signal compliance awareness; adaptation makes sure they are present.
- Matching audience expertise — a C-suite summary and a technical implementation guide need different language even when describing the same topic.
- Reducing hallucination risk — framing the model as a cautious domain expert and explicitly instructing it to flag uncertainty reduces confident-sounding wrong answers.
Tips
For regulated domains, always fill the regulatory field specifically rather than vaguely — “HIPAA, the FDA 21 CFR Part 11 requirements” is more effective than “healthcare regulations”. The more precisely you name the rules, the more precisely the model will reference them. Domain framing improves tone and relevance but never replaces human review for anything that carries legal, medical, or financial consequence.
