Pros & cons of Promptly AI
Free, small and does what it says: improve a prompt in place, keep the ones that worked, export the thread afterward. Works across the five major chat sites rather than only ChatGPT. The absence of any business model is the thing to weigh - a free extension with screen access to your AI conversations and no named operator is a trust question, not a feature question.
Pros
- Works inside ChatGPT, Claude, Gemini, DeepSeek and Copilot rather than one site
- Free with no account or card required
- Personal library plus a public curated template library
- Available on Chrome, Edge and Firefox
Cons
- No company, country or contact disclosed anywhere
- No team features, sharing or version history
- Free with no stated revenue model, which leaves its future uncertain
Best for
- People who write the same prompts repeatedly and want them one click away
- Improving a rough prompt without leaving the chat window
- Exporting or summarising long conversations
Not for
- Teams needing shared prompt libraries with versioning and access control
- Anyone whose policy bars extensions with access to AI chat content
Watch out: The extension reads and writes inside your AI chat windows, and no operating entity is named - check the Chrome Web Store permissions before installing on a work profile.
