100% Free to Start · AI-Powered · Standard .lrc Export
Time-sync your first song free, no account needed. This AI LRC generator listens to your track, transcribes it if you don't already have the words, and hands you back a ready-to-use .lrc file in seconds.
Upload a song and get line-by-line synced lyrics with AI.
Add an MP3, WAV, or M4A file — no account needed for your first song. Paste your own lyrics if you have them, or leave it blank and let AI transcribe from scratch.
This AI LRC generator recognizes each sung line (or word, for pasted lyrics) and matches it to the exact moment it's sung in the audio.
Skim the AI-generated timestamps, nudge any line that's slightly off, then download a standard, spec-compliant .lrc file.
Upload an MP3, WAV, or M4A and this AI LRC generator transcribes the vocals itself, free for your first song — nothing to type or paste first.
Paste your own lyrics or let AI transcribe them — either way, each line gets a precise timestamp without you tapping along.
Most songs finish syncing in well under a minute, whether you're on the free trial or a paid plan — far faster than timing each line yourself.
The underlying speech model isn't limited to English — it handles lyrics in dozens of languages out of the box.
Already have the words? Paste them and AI times each line. Starting from nothing? AI writes out the lyrics and timestamps together.
AI transcription can miss a word on a noisy mix or unusual pronunciation — re-tap or edit any line right in the same editor, no re-upload needed.
Every export is a clean, spec-compliant [mm:ss.xx] .lrc file that works in any LRC-compatible player — nothing proprietary.
Auto-sync a batch of songs fast instead of hand-timing each one — your first song's free, then spot-fix anything AI missed.
Get accurate timestamps in about the time it takes to upload the track, so the edit can start sooner.
Generate synced lyrics for an entire back catalog without hand-timing every track one by one.
AI transcribes straight from the audio, so there's nothing to track down or type out before you can start.
Auto-sync a song in the language you're learning — your first one's free — for a line-by-line reference to follow along with while listening.
Sync your first song under 5 minutes free — no sign-in, no credit card, so you can judge the accuracy for yourself before paying for anything.
Hand-timing a dense verse or a 5-minute song takes forever. AI times the whole thing in one pass, free or paid.
No lyrics on hand, no problem — this AI LRC generator can transcribe words you've never written down anywhere.
The timing you get isn't tied to this site — it's the same open .lrc file, ready to move to any music player or karaoke rig.
Every file this free AI LRC generator produces is a standard, non-proprietary .lrc — it opens anywhere regular LRC files do.
Streaming apps like Spotify and Apple Music run their own built-in synced-lyrics systems and don't read external .lrc files, so a file from here won't attach inside those apps — it's built for local players, karaoke rigs, and lyric-video software instead.
An LRC file is a plain-text lyrics format that pairs each line with a timestamp, like [00:12.50]. Music players, karaoke apps, and video editors read that timing to highlight or display lyrics in sync with the audio.
Yes — every account gets one AI-synced song under 5 minutes completely free, no card required, no trial that silently converts to a charge. After that, 1 credit covers 1 song regardless of length (up to your plan's per-song limit) — see Pricing for current pack prices.
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 goes 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.
No — your first AI-synced song (under 5 minutes) works right away, no sign-in required. 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. There's no way to do automatic transcription and syncing without sending the audio somewhere for these models to listen to.
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, free trial or paid.
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.
The free trial covers songs up to 5 minutes. Past that (or past your one free song), paid packs currently cover up to 6 or 10 minutes per song — see Pricing for exact limits per pack.
MP3, WAV, and M4A are all supported.
Yes. AI auto-sync hands off into a line-by-line editor — click any line, tap the spacebar 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. Your one free song and any paid credits 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 run their own built-in synced-lyrics systems and don't support external .lrc files.
Upload your first song under 5 minutes and see the timed lyrics file for yourself — free, no sign-in, no credit card.
