KOBUSHI
Matchup Notes for Tekken 8
日本語
One second on the VS screen,
your gameplan opens automatically.
KOBUSHI reads the Tekken 8 VS screen and instantly opens your matchup notes for both characters. Your own notes, frame data and move details — all in one screen you can check between matches.
Note: auto Match Scan is not available in the browser version.
Sign in by Sun, Aug 2, 23:59 (JST) and you can use the Community plan free, forever.

KOBUSHI in 30 seconds
From match detection to writing your counters — the whole flow in 30 seconds.
Sound on. The VS screen shown is an illustration, not actual game footage.
Match Scan — it's already open before you reach for the mouse.
Those tens of seconds of loading before a match? KOBUSHI reads both character names off the screen and opens your matchup sheet automatically (a desktop-app feature).
Finds the game window by itself
Auto-detects the TEKKEN 8 window and watches for the VS screen. Manual capture via hotkey (Ctrl+Shift+K) or button is also available.
Everything stays on your PC
Recognition is pure on-device image processing. No screenshots ever leave your machine, and the game itself is never touched.
Instant, with a tiny footprint
Each scan is a ~0.1s image check. While auto-scanning, expect around 1% of total CPU on a PC that runs Tekken 8 — and scanning stops entirely while the game isn't running.
Everything you need for the matchup, right here.
Your gameplan, their threats. One tap between them
Switch between your sheet and the opponent's by tapping the VS panel. Both follow the same order — Quick Check (the essentials before a match) → Matchup Notes (your strategy) → Cards (moves grouped by theme) — so switching never leaves you lost.
- Every command rendered as button icons
- Block frames are color-coded — safe or punishable at a glance
Full move details on hover
Hover any move: startup, hit level, block frames, hit states, move properties, related moves, and your own per-move notes — right there, with a TekkenDocs link when you want video.
Search by command, tags or frames
Filter by name, command input, tags (lows / heat / homing / punishable…) and startup frames. Drag any result straight onto a card.
Cards start auto-generated. You make them yours
Pick a character and KOBUSHI generates Heat / Homing / Lows / Stance cards from frame data. Leave those as they are, and add your own cards and notes on top.
Sign in, and everything is saved to the cloud.
Your notes and cards are stored on your device first. Sign in with Google or Discord and they're automatically saved to the cloud too.
Write it, and it's saved
There is no save button. Every edit is saved to the cloud automatically — and a warning appears only if something isn't working.
New PC, same gameplan
Just sign in on a new PC and all your notes and cards come back. Works across the Windows app and the web version too.
No account setup
Sign in with Google or Discord — no email forms, no passwords to manage.

Matchup knowledge, built together.
KOBUSHI is free because players build up and share their knowledge with each other.
What you enter helps everyone
The moves you add to quick checks and cards, and your move notes, are shared with the KOBUSHI community and shown to other users.
See others' answers on the spot
Community move notes appear right in the move details. Take an idea you hadn't thought of into your own notes with one tap.
Sharing is a condition of use
There is no setting to turn sharing off. Screenshots, and anything you haven't entered yourself, are never sent. Problem posts are handled by reporting and removal.

FAQ
Is it free?
Yes. Editing sheets, cards and notes, frame data, move search, and cloud auto-save are all free. Reading others' answers ("community move notes") and auto Match Scan are part of the Community plan ($2.99/mo). Sign in by Sun, Aug 2, 23:59 (JST) and you can use the Community plan free, forever. See Pricing for details.
Is what I enter shared?
Yes. KOBUSHI is free because players build up and share their knowledge with each other. The knowledge you enter (moves you add to quick checks and cards, your move notes, and so on) is shared with the KOBUSHI community and shown to other users. Screenshots, and anything you haven't entered yourself, are never sent. There is no setting to turn sharing off — sharing is a condition of use. Problem posts are handled by reporting and removal.
Can I use it on PS5 or Xbox?
If you have a capture card and streaming software (anything that can show the video in a window on your PC), KOBUSHI can read that window and run Match Scan. In Settings → Match Scan, choose "Playing on a console (PS5/Xbox, etc.)" and pick the window showing your video. Without a capture card, KOBUSHI cannot read console video on your PC.
Is this a cheat tool?
Match Scan works like taking a screenshot and reading the character names off the image. It never touches the game's process, memory or network, so it is not a cheat tool.
Does auto Match Scan slow down the game?
Each scan is a single ~0.05s image check, once per second. On a PC that runs Tekken 8, expect around 1% of total CPU — so we don't expect any noticeable impact on your game. If you're ever concerned, you can turn auto-scan off and use manual capture (button/hotkey) instead. Scanning also stops entirely while the game isn't running.
Are my screenshots uploaded anywhere?
No. All recognition runs on your PC. Nothing is sent to any server.
Where does the frame data come from?
Public data from Wavu Wiki, TekkenDocs and RBNorway, plus move details based on the Japanese guide site sorao.site (we summarize and iconify them in-app). Data may differ from the game after patches.
Windows shows "Windows protected your PC" when I run the installer
This SmartScreen warning appears because the app is not code-signed (no publisher certificate) — this is common for free, individually developed tools. Click "More info" and then "Run anyway" to start the installer. The warning reflects the absence of a certificate, not an inspection of the app's contents.
