If your browser blocks this site's cookies, it cannot remember that you are logged in.

Click the lock left of the address bar → allow cookies (site data), or open it in a normal window instead of a private window or strict tracking protection.

Google blocks login in in-app browsers. Use “Open in another browser” to open it in Chrome or Safari.

You must finish in the same browser within 10 minutes of starting. Allow cookies, then start again from the login page.

Check your spam/promotions folder and make sure the address has no typo. You can resend after a short wait, and there is a daily sending limit.

Requesting a new code invalidates the old one — enter the code from the latest email.

Too many wrong passwords lock the account. Finishing “Reset password” on the login page unlocks it right away.

“Too many attempts” clears after the time shown. On shared networks (office, school) others' attempts may count too.

Set a password in My account to also log in with email and password. You cannot unlink your last remaining login method.

When the terms change you must agree again to continue. Features that upload other people's audio, such as stem separation, require the copyright terms.

The server may be updating or restarting. Reload after 1–2 minutes, and check your internet connection.

Even if the connection drops, the job keeps running on the server. Check your library or the stem separation list before starting again — starting again uses credits again.

When offline, the app shows a saved page. You are not logged out — reload once you are connected.

Usage is counted in credits only. Each job costs a different number of credits (listed under “Usage limit” on the Account page); polishing a song you already made (switching takes, applying edits, reference mastering) costs nothing.

Credits for failed or canceled jobs are refunded. Your tier's credits refill on the 1st of each month, and unused credits do not roll over. If you need more, let us know through the contact below.

Lossless files (WAV, FLAC) and per-track WAV are higher-plan features. MP3 is available on every plan.

You can upload WAV, FLAC, OGG, MP3, M4A, AAC. Max per file 100MB — If larger, convert to MP3/M4A or split the song.

The file may be damaged or copy-protected (DRM). Try converting it to another format or use a different file.

Click the lock left of the address bar → Microphone → Allow, then reload.

If no permission prompt appears at all, your computer is blocking the browser's microphone — Mac: System Settings → Privacy & Security → Microphone · Windows: Settings → Privacy → Microphone. Turn the browser on, then reopen it.

The microphone works only on https — open https://chitty-ai.co.kr.

If another app (e.g. a video call) is using the microphone it can't be opened — close that app. Old browsers don't support recording — update to the latest Chrome, Edge or Safari.

If it says “Nothing was recorded”, check the input device and that the microphone isn't muted.

One recording can be about 8 minutes, up to 32 per song. Split long takes and delete unused recording tracks. If you were logged out, log in again.

Even before it is saved, you can download it with “Recording file” in the track menu.

Browsers don't play sound until you press something — press ▶ once more. On iPhone, turn off the silent switch and raise the volume.

If the phone runs low on memory it may fail to open tracks. Close other tabs or open it on a PC.

This happens when you were logged out or the connection dropped. Log in again and change it once more.

Only one person can edit a song at a time. It frees up when they close the window, or by itself after about 2 minutes.

A new window (popup) was blocked. Click the popup-blocked icon at the right of the address bar and allow this site.

The link expired or the sender revoked it. Ask the sender for a new link.

The address field is selected — press Ctrl(⌘)+C to copy.
