PrompTessor vs PromptTray

PrompTessor helps people draft, score and rework prompts for chat models like ChatGPT, Claude and Gemini, then keep the strongest versions in a reusable library.

A Chrome extension that stores reusable prompts and drops them into ChatGPT, Claude, Gemini and other chat, image and app builder tools with a keyboard shortcut.

About PrompTessor

PrompTessor is a browser workspace built around prompt quality rather than model choice. Users can start from a goal and have the generator draft a prompt, run an analysis that points out weak spots, pass a rough draft through the optimizer, or refine an existing version with feedback and formatting options. A reverse prompt tool reconstructs prompts from images, videos, URLs or text. Every version is kept in a history, and favourites can be stored in a library for later projects. The site says it handles multiple languages and is compatible with Gemini, Claude, ChatGPT and comparable models. A free start is offered, though the homepage does not list paid plan prices.

About PromptTray

PromptTray is a browser add on for Chrome, aimed at people who reuse the same prompts across different AI services. It adds a panel and a keyboard shortcut to 22 supported apps, including chat tools like ChatGPT, Claude and Perplexity, media tools like Runway and Suno, and app builders like Lovable and v0. A save button appears inside each app's message box, so a prompt can be filed without leaving the page, and prompts can include variables filled through a form. An import tool splits existing documents in Markdown, text, JSON or CSV into separate prompts. The free plan covers 30 prompts, and Premium costs 5 USD a month on annual billing.
