About Prompt Screener
Prompt Screener makes every prompt you send to AI more accurate, more specific, and less likely to produce biased, sycophantic, or hallucinated responses.
Works across all major AI chat platforms.
✦ PROMPT COACH — Optimize for the AI you're using
Every AI model responds differently. Prompt Screener analyzes your draft against each platform's official prompting best practices and helps you rebuild it for the specific AI you're using.
Click the Optimize button and Prompt Screener will:
· Analyze your draft using that platform's prompting guidelines
· Ask 1–3 targeted clarifying questions
· Assemble a fully optimized prompt tailored to how that specific AI thinks and responds
· Preserve your draft, data, and context verbatim
Each platform's optimization is built from official documentation.
Anti-hallucination and anti-sycophancy instructions are woven into every optimized prompt, so the AI gives you honest, grounded answers instead of telling you what you want to hear.
🔍 BIAS DETECTION — Catch skewed prompts before you send
Prompt Screener checks every prompt for five patterns that cause AI to produce one-sided or misleading responses:
· Confirmation-seeking — asking AI to validate a conclusion you've already reached
· Loaded presupposition — treating an unproven claim as an established fact
· Authority anchoring — using a previous AI answer to validate itself
· Outcome-leading — asking for evidence in only one direction
· False dichotomies — artificially limiting the options AI considers
If a pattern is detected, Prompt Screener intercepts the send and explains why — then suggests a neutral reframe. You can use the reframe, edit it, or send your original. If no bias is detected, your prompt sends instantly with zero interruption.
