Author: Prompt Sloth

One has a 4.8 rating and works on any website. The other doesn’t. Here’s the full breakdown.

Pretty Prompt and Prompt Sloth are close cousins.

Pretty Prompt adds a genuinely nice twist: a Refine mode that asks clarifying questions to tighten the prompt, plus a saved library with folders and cross-device sync, all tuned for ChatGPT, Claude, and Gemini.

The honest difference is breadth and the price of "unlimited." Pretty Prompt is built around a few big chat tools and charges $9.99/month for unlimited — its $4.99 tier caps you at 100 prompts a month. Prompt Sloth works on any website you enable plus 20+ AI tools natively, ships 2,000+ ready-made templates, and gives unlimited enhancements at $4.99/month.

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).
