What it is
PromptLane is a focused tool for collecting prompts that are actually useful in day-to-day work, instead of letting them disappear inside chat history.
Problem
When prompts live in scattered notes, they are hard to compare, hard to improve, and almost impossible to reuse across projects.
Approach
The interface is designed around fast iteration: save a prompt, compare revisions, attach context, and keep lightweight notes about what changed the output quality.
Outcome
The product is still evolving, but it already serves as a practical system for turning one-off prompt experiments into a reusable working library.
