Open the app in your browser
Navigate to https://bpdiary.arverma.dev/ in Chrome or any modern browser (Firefox, Edge, and Safari also work).The app loads as a static web page — there is no server-side processing. Once the page has loaded you can work offline; an internet connection is only needed to load the page for the first time.
Choose a template: Letter or Diary
In the header bar at the top of the page you will see a template segment control with two options:
- Letter — for official Hindi correspondence. The editor renders a single-column A4 page with a text area for the body of your letter.
- Diary — for FIR case diaries. The editor provides structured fields matching the standard diary format, including date, case number, and narrative sections.
You can maintain separate histories for letters and diaries. The History sidebar updates to show only the document type that is currently active.
Type your document
Click anywhere in the text area (or a diary field) and start typing. There are three ways to enter Hindi text:Use the Punctuation Panel (accessible from the toolbar) to insert the 9 essential Hindi punctuation symbols — danda (।), double danda (॥), and others — with a single click.

On a desktop or tablet, enable the Hindi Typing toggle (labelled A:अ) in the header. When the toggle is on, type in everyday Romanized Hindi — for example, type

Press Space to accept the first suggestion, or click any suggestion in the list to insert it.To turn off transliteration and type Devanagari directly (for example, using a system Devanagari keyboard), switch the toggle off.Your document saves automatically
You do not need to press a save button.

15 Jun 2025) and type a custom name. The name is saved along with the document.Documents are stored only in this browser on this device. If you want to access them on another device or protect them from accidental browser-data clearing, connect Google Drive backup from the History panel.
