The improve button lives inside the AI tool you're already using. It keeps your intent and your facts, and adds what's missing — role, context, constraints, format — so the AI delivers work you can send.
Your standard prompts, on a shortcut
Type // for 2,000+ proven templates — proposals, follow-ups, briefs, reports — or save your own with your scope language and client terminology, synced across devices.
Prompt wording is measurable, not cosmetic. Researchers at the University of Washington and the Allen Institute for AI found that prompt formatting changes alone can swing LLM accuracy by up to 76 points (Sclar et al., ICLR 2024), and adding a single reasoning sentence lifted one math benchmark from 17.7% to 78.7% accuracy (Kojima et al., NeurIPS 2022).
