Undo does not restore the expected state
stop applying transformations and recover from the source copy or downloaded file.
Text Scratchpad
Use a browser scratchpad for disposable text cleanup and extraction, with clear localStorage and shared-device warnings.
Developer & Text ToolsDirect answer
AppKiro Text Scratchpad is a plain-text workspace with case conversion, line cleanup, sorting, deduplication, text/regex find-and-replace and extraction of emails, URLs or numbers. The current page also uses localStorage autosave and provides copy, download and clear actions. Plain-text editing with native undo behavior.

How to use it
Enter the source data: Paste or type plain text and check whether autosave is enabled. Use synthetic data when testing regex or extraction patterns.
Choose the relevant settings: Apply one transformation at a time—case, whitespace, line sorting/deduplication, find/replace or extraction—and review the preview/result before replacing the source.
Review and verify the result: Copy or download the cleaned text, then use the clear-storage control and verify that the text is gone when working on a shared device.
Key capabilities
- Plain-text editing with native undo behavior.
- Case conversion and whitespace/line cleanup.
- Sort and deduplicate line operations.
- Text or regular-expression find and replace.
- Email/URL/number extraction, copy, TXT download and local autosave.
Best use cases
- Clean a pasted list before importing it elsewhere.
- Deduplicate and sort line-based data.
- Prototype a regex replacement or extract public values from sample text.
Limits and safety notes
- Transformations can destroy formatting or data when applied blindly. Regex replacement can alter unintended matches, URL decoding can fail on malformed percent sequences, and local autosave may persist sensitive text after the tab closes.
- Use sample or non-production data. The current page describes local processing, but sensitive secrets still require an independent code and network audit before this can be treated as a security guarantee.
- Autosave writes the draft to localStorage key appkiro-scratchpad after a one-second debounce. Clear removes both the editor text and that saved key after confirmation; browser storage has no guaranteed retention period.
Troubleshooting
Regex replacement fails
validate the pattern in the JavaScript Regex Tester and check flags/escaping.
Text returns after reopening
clear local storage through the page control and verify browser-site data if necessary.
Frequently asked questions
Where is scratchpad text stored?
Batch mode processes up to 200 non-empty lines and reports invalid rows. ZIP generation streams entries and releases each temporary data URL after it is added, which avoids retaining a second full set of generated images in component state.
Can I use regular expressions in find and replace?
Yes, the current scope includes text and regex modes. Validate the JavaScript expression and test on a copy before replacing the source.
How do I remove duplicate lines?
Use the line-deduplication action, then review whether comparison is case-sensitive and whether blank lines or whitespace are normalized before accepting the result.
Is it safe and private?
Short answer: Use sample or non-production data. The current page describes local processing, but sensitive secrets still require an independent code and network audit before this can be treated as a security guarantee.
Does it work on mobile?
The layout adapts to narrow screens. File selection, camera access, clipboard actions and downloads still depend on the permissions and capabilities of the mobile browser.
