AI-Powered · Free First Song · Standard .lrc Export
Upload a song and let AI auto-sync lyrics to the audio for you — no manual tapping required. Get a timed lyrics file in seconds, with or without pasting the words in first.
Upload a song and get line-by-line synced lyrics with AI.
Free song under 4 min available.
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, 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.
A full song is usually synced in well under a minute — far faster than timing each line by hand.
The underlying speech model handles dozens of languages, so it isn't limited to English lyrics.
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 in the same editor.
A clean, spec-compliant [mm:ss.xx]-timestamped .lrc file that works in any LRC-compatible player — no proprietary lock-in.
Timing a dense verse or a 5-minute song by hand takes forever. AI syncs the whole thing in one pass.
You don't need to already know every word — this AI LRC generator can transcribe lyrics you've never written down anywhere.
Try your first AI auto-sync under 4 minutes free, no sign-in and 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 timing each one by hand — 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.
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 this tool produces is a standard format — nothing proprietary about it, 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 a 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.
An LRC file is a plain-text lyrics format that pairs each line of lyrics with a timestamp, like [00:12.50]. Music players, karaoke apps, and video editors read this timing to highlight or display lyrics in sync with the audio.
Your audio is uploaded directly to temporary storage, then fal.ai's Demucs model isolates the vocals from any music or background noise, and that vocal track is sent to OpenAI's Whisper speech-recognition model, which transcribes it 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. The temporary copy of your audio is deleted once processing finishes.
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.
No — your first AI-synced song (under 4 minutes) works right away, no sign-in required. If you want more after that, we ask for your email at checkout so your credits are tied to an account you can use on any device, not just this browser.
Yes, and we say this plainly: your audio is uploaded to temporary storage (Supabase) and then sent to two third-party services — fal.ai (to isolate the vocals) and OpenAI (to transcribe them). That storage copy is deleted once processing finishes; nothing is kept around. This is what makes automatic transcription and syncing possible — there is no way to do it without sending the audio somewhere for these models to listen to.
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 adjusted by hand afterward.
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.
Yes. AI auto-sync hands off into a line-by-line editor — 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. Accuracy still depends on audio clarity, same as with any language.
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.
Most desktop and mobile music players read LRC files natively, including MusicBee, VLC, AIMP, and Poweramp; foobar2000 needs a lyrics plugin such as ESLyric. Streaming apps like Spotify and Apple Music use their own built-in synced-lyrics systems and don't support external .lrc files.
