Every track, stem, lyric and idea in one place, with an AI that organises, credits and connects it all for you. From the first voice note to the final master.

Kii isn't a chatbot bolted on the side. It runs through your whole catalogue, so the admin that normally eats your week just gets handled.
Drop in a messy folder of bounces and Kii sorts them into songs, versions and stems. Named, tagged and credited.
Ask it 'what have I got around 120 in a minor key' or 'have I written this line before'. You get a straight answer.
It learns who you work with, fills in missing credits and splits, and catches duplicates before they pile up.
Co-Writer sits in the lyric editor. Brainstorm titles, tighten lines, check the rhyme and meter without leaving the song.
What Kii suggests, you approve. It never changes your catalogue behind your back. And if it can't do something, it says so.

Locker is where your music stays organised. Tracks, versions, stems, lyrics, files, notes, and collaborators stay connected in one searchable workspace.

Comments, feedback, approvals, and shared context stay attached to the track instead of disappearing across email threads, messages, or download links.

Locker understands music workflows. Upload a stem pack or a full session and Locker groups related files, detects stems, and keeps versions linked behind the scenes.
From the first idea to final delivery, Locker supports writing, producing, organising, and releasing music in one connected system.
Capture ideas, versions, lyrics, and demos in one evolving workspace.
Manage stems, versions, notes, deliveries, and client feedback effortlessly.
Create searchable catalogues and track your roster with clarity.
Keep song assets, splits, metadata, and rights notes organised.
Streamline releases, sessions, and communication across your roster.
"Love it! What a game-changing tool. Everything's easier to find, quicker to manage, finally everything lives in one place."
