Mobile App Development Studio

Apps for Apple.
Apps for Google.
Built to last.

We design and develop native and cross-platform apps for iOS, macOS and Android — from the first idea to the App Store and Google Play.

Our App — Now on the Mac App Store

Chapter Generator
for YouTube

AI Chapters, Timestamps & SEO — only for Mac

Paste a video link and get ready-to-paste chapters, clean timestamps, and an SEO-ready description with hashtags. The publishing busywork, done for you — built for creators preparing chapters for their own uploads.

Requires macOS 14.0 or later. Not affiliated with, endorsed by, or sponsored by YouTube or Google LLC. YouTube is a trademark of Google LLC.

§

Captions-first

Reads the caption track and segments it into chapters — with server-side transcription when a video has none. The app never downloads audio or video.

AI

Your AI, your way

On-device Apple Intelligence, fast cloud AI, or a fully offline heuristic. A source badge always shows which one produced each result.

Creator workflow

Pick a target of 3–50 chapters, copy them, or jump straight to the video's YouTube Studio edit page with Copy & Open Studio.

Privacy by design

No account, no sign-in, never contacts youtube.com directly. One master toggle keeps everything on your Mac — nothing sent to any cloud AI.
