A little less repeat
Keep the useful stuff close.
Pastree is built around a simple idea: the text and files you use every day should be easier to find and reuse.
A small space beside your work
Browser work is full of repetition: the same introduction, a useful reference, a prompt worth refining, a document you need to attach again. Pastree brings clipboard history, reusable lists, prompts, and files into one browser extension workspace.
In Chrome, Pastree lives in a side panel. In Firefox, it opens in the sidebar. It is a browser extension, with no native desktop app or promised mobile extension.
Useful by choice
Start with manual saves. Automatic capture is off by default and uses optional site access when enabled. Local browser storage keeps your workspace in your profile, while some preferences may sync through your browser.
Pastree helps you prepare reusable prompts; it does not generate AI responses. You choose where to paste your text and attach your files.
