Small, local-first browser tools.
No accounts. No tracking. No uploads.
Your files stay on your device.

Tools

  • Clipped

    Trim and crop videos directly in your browser.

    Drop in a video, mark the section you want, and export. Trimming is fast and lossless. Cropping supports vertical and widescreen formats. Processing happens locally, so your video is not uploaded to lucyna.dev.

  • Musiced

    A local music library that lives in your browser.

    Import your own audio files, build playlists, manage your queue, and listen offline. Your library stays on your device — there is no lucyna.dev account.

    Musiced also includes discovery search across YouTube, iTunes, Deezer, SoundCloud, and Internet Archive. Results link out to the source platforms; lucyna.dev does not host, stream, or download third-party media.

  • Edet Work in progress

    A writing app for long fiction that lives in your browser.

    Write in chapters and scenes, rearrange them on an index-card board, and keep your characters, places, and plot in one place. Export to Word, EPUB, or PDF. Your writing stays on your device — no account required.

    Edet also checks your draft for repeated words, uneven pacing, and details that don't line up. It works offline; an optional account backs it up and syncs across your devices.

Why local-first?

Most media tools ask you to upload files before you can do anything. lucyna.dev is built the other way around: the browser does the work whenever possible.

The server ships the app and handles Musiced search requests. Your media files stay on your device.
