AI LRC Generator

Upload a song and let AI auto-sync lyrics to the audio for you — no tapping along required. Get a timed lyrics file in seconds, with or without pasting the words in first.

Prefer to time it yourself instead? Try the free manual tap-sync editor.

AI transcribes your audio and times every line automatically.

How AI auto-sync works

  1. 1

    Upload your audio

    Add an MP3, WAV, or M4A file — paste your own lyrics too if you have them, or leave it blank and let AI transcribe from scratch.

  2. 2

    AI transcribes and aligns

    The AI LRC generator recognizes every sung line (or word, for pasted lyrics) and matches it to the exact moment it's sung in the audio.

  3. 3

    Fine-tune and export

    Review the AI-generated timestamps, tap-adjust any line that's off, then download a standard, spec-compliant .lrc file.

Who uses AI lyric syncing

Where your synced lyrics file works

The .lrc file AI auto-sync produces is the same standard format as the manual tap-sync tool — nothing AI-specific about the output itself, so it opens anywhere regular LRC files do.

Streaming apps like Spotify and Apple Music use their own built-in synced-lyrics systems and don't read external .lrc files, so an AI-generated file from this tool won't attach to a track inside those apps — it's meant for local players, karaoke rigs, and lyric-video software instead.

Frequently asked questions

How does the AI LRC generator work?

It sends your audio to OpenAI's Whisper speech-recognition model, which transcribes the vocals and returns word-level timing. That timing is matched against your lyrics (or, if you didn't paste any, against Whisper's own transcription) to build a standard .lrc file automatically.

Is AI auto-sync free?

Every account gets one AI-synced song under 4 minutes free, no card required. After that, 1 credit covers 1 song regardless of length (up to your plan's per-song limit) — see the Pricing page for current pack prices.

Do I need to sign in to use AI auto-sync?

Yes. AI auto-sync is the one part of this site that requires an account — it's how we track your free song and any credits you've bought. The manual tap-sync editor never requires sign-in.

Is my audio uploaded when I use AI auto-sync?

Yes, and we say this plainly because it's the one exception to how this site normally works: AI auto-sync sends your audio to OpenAI for transcription. If you'd rather keep everything local, use the manual tap-sync editor instead — it never uploads anything.

How accurate is AI lyric syncing?

It's usually close, especially on a clear vocal mix, but not perfect — background noise, overlapping vocals, or unusual pronunciation can throw off a line or two. Any line can be re-tapped or adjusted by hand afterward, the same way as standard tap-sync.

Can AI generate word-by-word (enhanced) LRC files?

Not yet — AI auto-sync currently produces standard line-level LRC, where each full line gets one timestamp. Word-by-word "enhanced" LRC (the A2 format) isn't supported.

What's the longest song AI auto-sync supports?

That depends on your plan's per-song limit — the free trial covers songs up to 4 minutes, paid packs currently cover up to 6 or 10 minutes per song. See Pricing for exact limits per pack.

What audio formats does it accept?

MP3, WAV, and M4A are supported, matching the manual tap-sync tool.

Can I still fix a line manually after AI syncs it?

Yes. AI auto-sync hands off into the exact same editor as manual tap-sync — click any line, tap Space at the right moment to re-time it, or use Undo.

Does AI LRC generation work in languages other than English?

Yes — the underlying speech model supports dozens of languages, so it isn't limited to English vocals the way some simpler lyric tools are. Accuracy still depends on audio clarity, same as with any language.

What happens if AI mishears a lyric?

You'll see it in the generated lyrics before you export — since AI auto-sync opens into the same line-by-line editor as manual tap-sync, you can correct the text or re-time the line by hand before downloading the file.

Is this the same as a lyrics generator that writes new lyrics?

No — tools that call themselves a "lyrics generator" usually write brand-new song lyrics from a prompt. This AI LRC generator does the opposite: it takes a song you already have and produces a timed lyrics file from it, either by transcribing the audio or aligning lyrics you paste in.

Do I lose my credits if the AI transcription fails?

No. Credits (and your one free song) are only ever used after a transcription actually succeeds — if the request fails for any reason, from a bad file to a network error, nothing is deducted and you can retry.

Can I use AI auto-sync on instrumental or vocal-heavy tracks equally well?

AI auto-sync is built for vocal tracks — it needs sung or spoken words to transcribe and time. A purely instrumental track has nothing for it to transcribe, so the manual tap-sync editor is the better fit if you're timing something without vocals.
