# HanoLab > HanoLab is a browser-based voice conversion and voice cloning tool for recorded speech and singing. Upload or record audio, choose a private voice, preview the conversion, and download the result. Additional tools include stem separation, music generation, and reference mastering. HanoLab runs entirely in the browser and bills with credits, not per-seat subscriptions. The free plan includes 30 credits per month with no credit card required. Voice models you train are always private to your account: there is no public voice marketplace and no sharing toggle that can expose them by accident. Every voice training run requires an explicit consent attestation. ## Core capabilities - [AI voice changer](https://hanolab.com/use-cases/voice-changer): Convert recorded speech or singing through a voice in your private library. This is audio-to-audio conversion, not live microphone effects or text-to-speech. Start with a clean short recording and listen before converting a longer take. - [AI voice cloning](https://hanolab.com/use-cases/voice-cloning): Clone your own voice or a voice you have permission to use. Flash starts from a clean 10-second sample; Pro uses a longer, varied dataset, often around 5 minutes. Convert recordings through the clone. Quality and processing time vary with the source, target voice, and workload. - [AI cover songs](https://hanolab.com/use-cases/ai-cover-songs): Convert any vocal through any voice in your library — same phrasing, new singer. Stack harmonies in your own voice, or demo a topline in a target voice. - [Music generation](https://hanolab.com/use-cases/music-generation): Turn a one-line theme into a full multi-section track in your language, from a quick sketch to studio-quality polish. - [Stem separation](https://hanolab.com/use-cases/stem-separation): Split any song into six stems — vocals, drums, bass, guitar, piano, and other — for remixing, sampling, or re-mixing without the original session. - [Reference mastering](https://hanolab.com/use-cases/mastering): Match the loudness and spectral balance of any commercial reference track, with lossless export. ## Key pages - [Home](https://hanolab.com/): Product overview and canvas demo. - [Use cases](https://hanolab.com/use-cases): What creators build on HanoLab. - [Voice cloning guide](https://hanolab.com/use-cases/voice-cloning): How AI voice cloning works, Flash vs Pro, and FAQ. - [AI cover songs guide](https://hanolab.com/use-cases/ai-cover-songs): How to make an AI cover — get a clean vocal, pick or clone the target voice, convert, mix, and master. - [Stem separation guide](https://hanolab.com/use-cases/stem-separation): Split a song into six stems for acapellas, instrumentals, remixing, and sampling. - [Music generation guide](https://hanolab.com/use-cases/music-generation): Turn a prompt or lyrics into a full multi-section track, from a quick sketch to studio polish. - [Mastering guide](https://hanolab.com/use-cases/mastering): Match a mix to a commercial reference's loudness and tonal balance, with lossless export. - [Vocal remover guide](https://hanolab.com/use-cases/vocal-remover): Remove vocals for a clean instrumental, or isolate the acapella, from any song. - [Voice changer guide](https://hanolab.com/use-cases/voice-changer): Change the voice in any recording — convert audio through a different voice while keeping the words and delivery. - [Choosing an AI voice cloning tool](https://hanolab.com/compare/ai-voice-cloning): A buyer's guide — what to evaluate (privacy, speed, ownership, pricing model) before you pick a tool. - [Choosing an AI cover song tool](https://hanolab.com/compare/ai-cover-song-tools): A buyer's guide — own-voice support, phrasing preservation, stem splitting, output quality, and pricing model. - [Choosing a stem separation tool](https://hanolab.com/compare/stem-separation-tools): A buyer's guide — number of stems, separation quality, file-length limits, lossless export, and pricing model. - [Pricing](https://hanolab.com/pricing): Plans and per-action credit costs. - [Discover](https://hanolab.com/discover): Public tracks made by HanoLab creators. - [Blog](https://hanolab.com/blog): Guides and how-tos for voice cloning, covers, and music production. - [How to make an AI cover song](https://hanolab.com/blog/how-to-make-an-ai-cover-song): Step-by-step guide to a natural-sounding AI cover. - [How to remove vocals from a song](https://hanolab.com/blog/how-to-remove-vocals-from-a-song): Get a clean instrumental and the isolated acapella from any track. - [How much audio to clone a voice](https://hanolab.com/blog/how-much-audio-to-clone-a-voice): How much reference audio a voice clone actually needs. - [Flash vs Pro voice cloning](https://hanolab.com/blog/flash-vs-pro-voice-cloning): When to use a fast clone versus a studio-grade one. - [Features](https://hanolab.com/features): Full feature list. ## Good to know - Pricing model: credits, not seats.
