Tempify
Instant Scratchpad & Temporary Text Buffer
“How do you build a scratchpad that never loses your text?”
Case Study Index (4 Sections)↓
Why I Built This Tool
Developers constantly need a disposable, zero-friction text buffer to paste code snippets, draft emails, or clean text without creating temporary files. Tempify opens instantly and preserves content across browser sessions without accounts or cloud databases.
I was tired of creating random `temp.txt` files on my desktop just to store quick code snippets during development.
Technical Implementation
Synchronizes textarea mutations directly to `window.localStorage` inside a React `useEffect` binding, enabling zero-latency persistence.
Design Approach: Eliminate all friction between opening the app and typing text—no logins, no title fields, no manual save buttons.
Engineering Decisions
Debouncing storage writes risked losing the last typed characters if the browser tab closed unexpectedly.
Wrote directly to `localStorage` synchronously on every state update, optimized because string buffer payloads are small.
Minimal synchronous storage write per keypress.
Zero data loss even on unexpected tab closure or system crash.
Challenges & Solutions
Clean Split View Layout on Mobile
Issue: Split-pane editor and markdown preview overflowed on narrow screens.
Decision/Solution: Added a tabbed toggle mode (Edit / Preview) that activates automatically on mobile breakpoints.

Key Takeaways
Single-purpose tools must prioritize speed and reliability above all else.
