Count Reading Nights for a List at Your Own Pace

A reading list shrinks faster when you already know your nightly pace. Convert remaining pages into evenings, and keep a partially finished book visible instead of counting it as done.

1 · book | total pages | pages already read

FIRST-LOAD

Research prototype — checkout unavailable. Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.

Data note: Everything runs in this browser tab on the nightly page ruler: your book | total pages | pages already read stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.

Perspective: Before: Reference books often read at a different speed from novels. After: the nightly page ruler shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Optional AI formatting, not calculation

For this nightly page ruler, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.

Format my non-sensitive notes for a nightly page ruler. Return plain rows only: book | total pages | pages already read. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.

Accepted schema: book | total pages | pages already read. No AI response is executed as code.
