Common questions
What limitations apply?
Deterministic template, not an AI model. Review generated prompts and AI responses; do not include private data in external services.
Is my input saved?
No. It stays in browser memory and clears on refresh. Successful actions record only a stable tool ID and name, never your entered data.
