FOUR MODULES
One pipeline, from footage to conclusions
Four pages over the same local data: matches hold the files, rallies hold the time, shots hold each hit, stats hold the verdict.
Matches
Register a local recording as a match. The file stays where it is; only the path is stored.
- Search by match, player, or tag
- Relink in one click after a move
- Players, date, notes, and tags
Rallies
Find live rallies automatically, then string every point together through the scoreboard.
- Detected start/end, adjustable frame by frame
- Scoreboard reading with scoring-rule checks
- Fill missed rallies from the ball arc, export clips
Shots
Find hit points first, confirm them yourself, then classify — the order stays yours.
- Four-corner court calibration for position and landing
- Hit points you can drag, add, or remove
- Manual shot types are never overwritten
Stats
Turn shot-by-shot data into a match report you can actually review.
- Landing map and shot-mix radar
- Rally speed monitor and length distribution
- Per-game or whole match: win rate, winners, errors
HOW IT WORKS
Three steps from a raw file to a conclusion
The heavy lifting runs locally; the pages only ask you to confirm and correct.
- 01
Add a match
Pick a local recording and fill in players and date. The original is never copied or uploaded.
- 02
Detect rallies, calibrate the court
Rallies are cut automatically; drag the timeline to fix boundaries, then mark four court corners.
- 03
Confirm hits, read the numbers
Confirm each hit point, classify the shots, then look at landings, shot mix, and rally rhythm.
FREE VS PRO

LOCAL FIRST
Your footage never leaves the machine
Pro analyses everything locally. Database, models, and clips live in a local folder; the account is only used to check your membership.
Paths, not copies
A match stores only its file path. Video files are never copied or uploaded.
Local database
Rallies, hit points, annotations, and stats live in a local SQLite file you can back up or move.
Works offline
Your membership is cached for 7 days, so you can keep analysing without a connection.

FAQ
Questions you may have
Does Pro upload my footage?
No. Rally detection, shot analysis, and stats all run locally; video never touches a server. Signing in only verifies your membership.
Is Smart Edit in the browser still available?
Yes, and it stays free. Pro adds per-shot data and keeps your matches on disk.
Do I need to subscribe again on a new computer?
No. Membership follows the account — sign in on the new machine. Local data does not sync, so copy it across yourself.
What happens to my local data when the membership lapses?
Nothing is deleted. Matches, rallies, and shot results stay on disk and are usable again once you renew.
Which video formats are supported?
Common containers such as MP4 / MOV / MKV / AVI / WebM, decoded by the FFmpeg bundled with the desktop app.
