ZASSHA - How to Use
ZASSHA turns your screen recordings into clear, reproducible steps you can share. Upload a video, click Analyze, and export to Word, PowerPoint, or Excel.
This README focuses on everyday use. A short developer note is at the end.
Quick Start (5 minutes)
First run tip: start with a short recording (≤ 5 minutes, ~100 MB). It keeps upload/analysis fast while you validate the flow.

How To Use
Add videos
Drag & drop files into the left sidebar, or click the upload area and pick video/* files.
Choose analysis mode
Summary: short, concise output (500–800 chars).
Detail: full step‑by‑step output with timestamps and tools.
(Optional) Add a hint
Write a short sentence about the task or goal (e.g., “Change Slack notification settings”). This improves accuracy.
Click Analyze
Progress appears per file. Large files (≥ 50 MB) upload in resumable chunks automatically.
Review the result
Overview: short description of the video.
Business Inference: what the operator is trying to check/confirm.
Business Details: a table of steps and operations. Each operation shows a thumbnail; hover to preview the clip, click to open a larger player.
Export your document
Click Export on the file’s card and choose:
Word (.docx): headings + text with screenshots.
PowerPoint (.pptx): one slide per operation. Screenshot + caption on the slide; details (Used Tool / Timestamp / Inference) in slide Notes.
Excel (.xlsx): rows with No., Step, Inference, Used Tool, Timestamp, Operation.
Filenames are like zassha__.*.
Switch language and theme
Footer: EN/JA toggle; light/dark theme toggle.
Record Your Screen (macOS / Windows)
macOS (built‑in)
Shortcut: press Shift + Command + 5 → choose “Record Entire Screen” or “Record Selected Portion” → click Record. Stop from the menu bar Stop button (or Command + Control + Esc). The default save location is Desktop unless changed in Options.
QuickTime Player: open QuickTime → File → New Screen Recording → choose mic if needed → click Record. Stop from the menu bar.
Windows (built‑in)
Xbox Game Bar: press Win + G to open, then Win + Alt + R to start/stop recording. Files are saved under Videos/Captures by default.
Snipping Tool (Windows 11): open Snipping Tool → switch to the Record tab → New → select the area → Start. When done, stop and save the file.
Tips For Better Results
Keep the recording focused on the task; avoid rapid app switching.
Record at 1080p+ if possible; UI text becomes easier to recognize.
Enter a hint when the goal isn’t obvious from the video alone.
