A: QuickLRC is an AI-powered platform that creates perfectly synchronized lyrics files from audio. We offer four main tools: LRC Maker for manual editing, LRC Generator for AI-powered automatic generation, Enhanced LRC Generator for word-level karaoke timestamps, and Lyrics Extractor for AI transcription with timing. Q: What types of lyrics files can I create? A: We support multiple formats including LRC (with timestamps), Enhanced LRC (word-level timestamps), SRT subtitles, WebVTT captions, TTML files, and ASS files. Each format serves different purposes from basic lyrics display to advanced karaoke applications. Q: What is an LRC file and how do I use it? A: An LRC file is a synchronized lyrics format that contains lyrics with precise timestamps. It's widely used for karaoke apps, music players, and streaming services. Each line starts with a timestamp [mm:ss.xx] followed by the lyrics. You can open LRC files in music players like KMPlayer, VLC, or mobile apps like Spotify and Apple Music. Q: Do I need to sign up to use QuickLRC? A: You can use our manual sync feature for free without an account. However, you need to create an account to access our AI-powered features like automatic transcription and AI sync. We offer subscription plans for regular use of AI features. Q: What's the difference between LRC Maker and LRC Generator? A: LRC Maker is for manually creating and editing LRC files with precise control over timing. LRC Generator uses AI to automatically generate LRC files from audio using advanced transcription technology, saving time by creating both lyrics and timing automatically. Q: What's the Enhanced LRC Generator? A: Enhanced LRC Generator creates word-level timestamps instead of line-level timestamps. This means each individual word gets its own precise timestamp, perfect for karaoke-style applications where you want to highlight each word as it's sung. Q: What's the Lyrics Extractor? A: Lyrics Extractor uses AI to automatically transcribe audio into lyrics text with timing information. It listens to your audio file and generates both the lyrics content and synchronized timestamps, eliminating the need to manually type or search for lyrics. Q: How do credits work and what are the pricing plans? A: We offer flexible subscription plans with monthly credit allocations. Credits are consumed based on audio duration - for example, a 3-minute audio file requires 3 mins credits. Enhanced LRC Generator consumes 4x credits (a 3-minute file requires 12 mins credits) due to advanced word-level processing. Q: Can I cancel my subscription anytime? A: Yes, you can cancel your subscription at any time through your account billing settings at https://billing.stripe.com/p/login/bJe28rd2B56n5Aig3I9AA00. After cancellation, your unused credits remain available until they're used or your billing cycle ends. Q: Can I cancel my 3-day trial anytime? A: Yes, you can cancel your 3-day trial at any time through your account billing settings. After cancellation, your trial access remains available until the trial period ends. You won't be charged when the trial ends. Q: Do you offer refunds? A: Under normal circumstances, we do not offer refunds.
