FineShare Singify is a web-based music-generation service that creates songs from text prompts, lyrics, images, videos, and audio. It can generate tracks up to 4–4.5 minutes and export them as MP3 or FLAC. Listed tools include AI covers, singing voice cloning, stem splitting, music extension, lyric generation, key and BPM finding, and vocal removal. Image uploads can be up to 3 MB, with JPG and PNG among the supported formats; audio uploads can be up to 20 minutes. The service lists 1,000 voices and supports vocal and instrumental uploads and custom voice creation. Free users receive a wait queue and cannot download songs; their generated output license is limited to lawful internal, non-commercial use with attribution to Singify. Paid users own generated output but grant Singify a broad royalty-free license to use it, including commercially. Prices listed are Basic at $9.99 a month, Pro at $8.33 a month billed annually, and Enterprise at $24.99 a month billed annually. The homepage calls generated music 100% royalty-free, while the terms specify different output rights by plan. The pricing FAQ says unused characters and minutes do not roll over.

SoulX-Singer is a singing voice synthesis model that generates voices for singers it has not been tuned on. Pitch, rhythm, and expression can be guided by melody-conditioned F0 contours or score-conditioned MIDI notes. Its voice-conversion system changes raw singing audio to a target singer’s voice while retaining melody, rhythm, and lyrics, without requiring lyric or MIDI transcriptions. It supports Mandarin Chinese, English, and Cantonese, plus singer-timbre cloning, cross-lingual synthesis, and lyric editing while retaining natural prosody. Preprocessing tools handle vocal separation, dereverberation, F0 extraction, voice activity detection, and lyric and note transcription. Users can edit MIDI metadata, including lyrics, phoneme alignment, pitches, and durations, before synthesis. Soul-AILab provides generation and conversion demos and a separate MIDI editor through Hugging Face Spaces; the repository also supports local inference. Code and model weights use the Apache 2.0 license. Maintainers caution that automatic preprocessing may misalign singing with lyrics and notes, so manual correction may be needed.
