FAQ

TaikoForge is an online AI tool that turns any song into a Taiko no Tatsujin–style drum chart. Upload a track and it analyzes the rhythm, generates a standard TJA chart, and lets you play it in the browser or export a 1080p gameplay video.

TJA is the chart format commonly used by Taiko simulators — a plain-text file that records the timing of every note (don/ka) and each difficulty. TaikoForge outputs standard TJA that you can import into popular Taiko simulators.

Common formats like MP3, WAV, OGG, FLAC and M4A all work, and you can also drop in video files such as mp4/mkv (the audio track is extracted automatically). Uploads are converted to OGG for processing.

You can play them right away in TaikoForge's in-browser player with the keyboard (DFJK), or download the TJA and import it into Taiko-web, TJAPlayer and other simulators that support TJA.

There's a free tier you can start with right away; upgrade to a paid plan when you need more chart credits or video generation. It is a monthly subscription you can cancel anytime.

You must own or have the right to use the music you upload. TaikoForge only uses it to analyze the rhythm and generate your own chart — we do not publicly redistribute your audio, and the chart is AI-generated.

Yes. Pick a chart and difficulty and it renders a 1920×1080 gameplay video with hit sounds — you can even stack several difficulties in one frame and add a background and fade in/out.

No installation — everything runs in your browser. Most songs generate a chart in a few tens of seconds to about a minute.
