Week 5 of the 50-app year · systematize your AI workflow

Stop losing your best prompts in a Notes app.

One searchable library for every prompt you rely on — with fill-in variables, version history, and one-click run in Claude or ChatGPT. It lives in your browser; your prompts stay yours.

Built by Kalilur Rahman482 certifications, 293 courses, ships an app a week. His one rule for learning fast: systematize everything. PromptStack is how he organizes 300+ prompts. Your data is stored only in this browser.
Why it sticks

A prompt you can't find is a prompt you rewrite

1

Capture

Save any prompt with a title, folder and tags. A dozen starters are already loaded so you're never staring at a blank library.

2

Templatize

Wrap the changing bits in {{variables}}. PromptStack turns them into fill-in fields so one prompt serves a hundred uses.

3

Run

Fill, copy, or one-click open straight in Claude or ChatGPT — no more paste-hunting across tabs.

4

Evolve

Version history (Pro) keeps every past wording, so improving a prompt never means losing the one that worked.
