Promptly AI is a “personal prompt engineer” that helps you get better results from ChatGPT, Claude, Perplexity, Gemini, DeepSeek, and other AI services. It works via a Chrome extension (also supports Edge and Firefox) plus a web playground.
Prompt engineering tools
Promptly AI suggests ways to refine your requests with quick rewrites, clarifications, and expansions. This helps reduce unhelpful outputs and saves time spent iterating on wording.
Prompt library and organization
A built-in library of curated prompts makes it easier to find ready-to-use templates for different tasks. You can also save, organize, and reuse your own best prompts to build a personal knowledge repository.
Export and compare AI conversations
Promptly AI simplifies moving and exporting conversations between models. This supports side-by-side comparison of responses from ChatGPT, Claude, Perplexity, Gemini, and DeepSeek, and makes it easier to share chats with a team or reuse them in documentation and reports.
