Answering "what did you change after you sent it?" in one sentence

With the programs you already use

• Word: turn on Review › Track Changes and every edit after that is marked. You have to turn it on before you send, and the recipient sees the marks as they are. If it was not on, Review › Compare compares two files.
• PowerPoint: Review › Compare compares two files. The changed slides are marked, but you still page through thirty slides one by one.
• Excel: there is nothing much inside the program for comparing cell by cell, so most people put two sheets side by side and look.
• By hand: you write "fixed the conclusion on page 3, replaced the chart on slide 7" in the email. The most common way, and the one most often forgotten.

They share one problem. Unless you pin down the moment you sent it somewhere, there is nothing to compare against. So you make a separate copy of "the version I sent", and that copy becomes `deck_sent.pptx`.

From the history

If you have handed your working folder to Octorium, there are three steps.

1. The moment you send it, click Bookmark on that line of the timeline and give it the Sent to client label (pick it from the suggestion chips or type your own).
2. Work the feedback in. Save as you always do; Octorium keeps the history.
3. When "what did you change?" arrives, choose the labelled line and click the Now tab. Every file that changed since you sent it is listed with an Added, Changed or Deleted badge (including changes not yet recorded), and Tell me what changed turns it into one sentence.

The description is written from inside the files. For Word, PowerPoint and Excel it speaks at the level of titles and counts: "Added the ‘Competitive analysis’ and ‘Revenue model’ slides", "Reworked the ‘Conclusion’ section, 120 more words", "Changed the formulas in the Budget sheet". Not which page and line, and not a sentence-by-sentence red and green. For one line of a reply, that is enough.

The habit of labelling

Not only "sent": if you put the words people actually remember on moments — Approved, Presented, First draft, Second draft — then later you type that word into Search for what you remember and go straight to that moment. A label does not change the file name; the folder still holds one file, as it was.
