A BACKGROUND NOTE CAPTURE UTILITY

FIELD MANUAL · FOR PEOPLE WHO READ MORE THAN THEY FILE

It writes the note.
You keep reading.

Casrion sits in the system tray and listens for a handful of hotkeys. Copy a passage, press one, and it is already a Markdown note, formatted, dated, and stamped with where it came from. You never switch windows.

Procedure

THREE SECONDS FROM SEEN TO SAVED

Fig. 1a · Something worth keeping appears.
1

Copy anywhere

An article, a chat answer, a formula, a screenshot. If you can copy it, Casrion can keep it. The app stays hidden in the tray the whole time.

2

Press one hotkey

Choose how it lands: plain text, heading, list, table, code block or colored emphasis. A quiet toast confirms the capture without stealing focus.

3

It is already a note

Everything arrives as clean Markdown in a file you chose. Math renders, tables align, screenshots embed. Open the window later and it is all there.

§02

Instruments

INVENTORY OF THE TOOLKIT

2.1

Global capture hotkeys

Fifteen shortcuts that work in every application. Text, headings, lists, code, screenshots, colored highlights and more, each lands formatted.

2.2

Voice memos

One hotkey starts recording, the same one stops it. The audio clip embeds directly in your note with a player, ready to replay while you review.

2.3

Source stamps

Optional stamps remember where every capture came from: the window, the app, and the exact web address when you copy from a browser.

Provenance

EVERY FACT REMEMBERS WHERE IT CAME FROM

Turn on the paperclip and each capture quietly records its origin. Copy from a browser and the exact page address is saved with it. Weeks later, right-click any passage and jump straight back to the source.

  • Window title, application and web address
  • Clickable links back to the original page
  • One click on the paperclip turns it off

The vanishing point sits on the horizon line, and every orthogonal in the scene converges toward it.

The quick writer

YOUR OWN THOUGHTS, WITHOUT BREAKING FLOW

Not everything is a copy. Press Ctrl+Shift+Q and a small writer floats over whatever you are doing. Add a heading, jot a thought, quote a line. Enter sends it to your note and gets out of the way. Ctrl+Enter keeps it open for more.

  • Headings, lists and quotes with one keystroke
  • Markdown works as you type
  • Drafts survive if you get interrupted

        §A
        
Appendix: questions

        
FAIR QUESTIONS, STRAIGHT ANSWERS

      


      

        A.1Windows says "Windows protected your PC". Is this safe?
        
Yes. That notice is Microsoft SmartScreen, and it appears for any new installer that is not signed with a paid code-signing certificate. It does not mean anything harmful was found. Click More info, then Run anyway. This appears once, only at install time.

      

      

        A.2Where are my notes stored?
        
In ordinary Markdown files, inside folders you pick yourself. Screenshots and voice memos sit in an assets folder next to each note. You can open, move, back up or sync them with any tool you like.

      

      

        A.3Does it need an internet connection?
        
No. Casrion is completely offline. It makes no network requests at all: no account, no sync servers, no analytics. It works the same on a plane as it does at home.

      

      

        A.4How do I quit or update it?
        
Closing the window keeps Casrion capturing from the system tray. To quit fully, right-click the tray icon and choose Quit. To update, request the newer installer from this page and run it over your existing install. Your notes are never touched.

      

      

        A.5Why is the download sent by email?
        
So each copy can be counted honestly. You enter your address, confirm it once, and the installer link lands in your inbox. That is the whole exchange: no newsletter follows, and the automated message includes an unsubscribe link if you never want to hear about updates.
