Why ShelfCue?
Instant results
Every analysis tool updates in real time as you type: word count, character count, reading time. No submit button, no spinner, no delay. You see results the moment you start typing.
Tools that transform text (sort lines, remove duplicates, case converter) apply in one click and show a before/after character count so you always know exactly what changed.
Genuinely private
ShelfCue has no server-side text processing. There is no endpoint that receives your input. All tool logic is JavaScript running locally in your browser tab.
You can verify this in 30 seconds: open your browser's developer tools, go to the Network tab, paste text into any tool, and confirm that zero requests are made containing your content.
No friction
No account. No email. No password. No free trial that expires. No feature locked behind a subscription. Open a tool, use it, close the tab.
