AI-Powered · Free First Song · Standard .lrc Export
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.
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.
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.
Review the AI-generated timestamps, tap-adjust any line that's off, then download a standard, spec-compliant .lrc file.
No lyrics on hand? The AI LRC generator listens to your song and transcribes the vocals itself — you don't have to type or paste anything first.
Whether you paste your own lyrics or let AI transcribe them, every line gets a precise timestamp automatically — no manual tapping required.
A full song is usually synced in well under a minute, versus several minutes of tapping along by hand for a typical 3-4 minute track.
The underlying speech model handles dozens of languages, so AI auto-sync isn't limited to English lyrics the way some rule-based lyric tools are.
Already have the lyrics written out? Paste them in and AI still does all the timing — you skip typing them from scratch, but keep your exact wording.
Have lyrics already? Paste them and AI times each line to your audio. Starting from nothing? AI generates the lyrics and timestamps together.
AI transcription isn't always perfect on noisy mixes or unusual pronunciation — any line can be re-tapped or nudged afterward using the same tap-sync editor.
Same [mm:ss.xx]-timestamped .lrc format as our manual tap-sync tool — the file works in any LRC-compatible player, there's no proprietary lock-in.
Tapping along by hand gets tedious on a dense verse or a 5-minute song. AI auto-sync handles the whole thing in one pass.
You don't need to already know every word — the AI LRC generator can transcribe lyrics you've never written down anywhere.
Every account gets one AI auto-sync under 4 minutes free, no credit card, so you can see the accuracy before paying for more.
AI-generated timing isn't locked into our site — it's the same open .lrc file you can move between music players or karaoke software.
Auto-sync a batch of songs fast instead of tapping through each one — then spot-fix any line the AI missed.
Get accurate timestamps in the time it takes to upload the track, so you can start building the video sooner.
Generate synced lyrics for an entire back catalog without manually timing every track by hand.
AI transcribes straight from the audio, so you don't need to track down or type out lyrics before you can start.
Auto-sync a song in a language you're learning to get a line-by-line reference you can follow along with while listening.
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.
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.
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.
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.
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.
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.
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.
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.
MP3, WAV, and M4A are supported, matching the manual tap-sync tool.
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.
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.
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.
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.
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.
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.
