Custom Instructions
Inject your own AI prompts to extract domain-specific insights from every transcription. Build QA scorecards, compliance checklists, and custom analysis workflows. Requires Pro plan ($0.39/hr).
How It Works
Pass an instructions field with your custom prompt (max 2,000 characters). The AI will process your prompt against the full transcript and return structured results in ai_analysis.custom_instructions_result.

Security
Injection protection: Custom instructions are sanitized server-side to prevent prompt injection attacks. Instructions attempting to override system behavior are silently dropped.
