BuboHub: HTML & LLM Files

HTML viewer. Organize your AI files easily.

Meet Viby Owl and his nest: BuboHub

A serious tool with a friendly face. BuboHub is a private, offline library for the files you actually use — the HTML pages you built with an AI, your Markdown notes, the PDFs you meant to read, the JSON you're saving just in case.

One purchase. iPhone, iPad and Mac. No account, no cloud, no subscription. Nothing leaves your device.

THE HTML PART IS THE GOOD PART

AI tools hand you working single-file HTML now — calculators, planners, dashboards, little generators. Most apps show you the source code. BuboHub opens the page and runs it.

Read it fullscreen. Tap any text to edit it, or open the source if you want to get your hands dirty. No laptop needed.

And it's a real page, not a preview. Buttons work. Forms work. Sliders slide. Your page has a print button? It prints.

SHELVES, NOT FOLDERS

Every file type gets its own shelf, with a live count on the tab:

• HTML — run, read fullscreen, edit text or source, share
• Markdown, text and JSON — read, edit, share
• Word and PDF — read with system Quick Look, share
• CSV — read as a real table, not raw text
• File Explorer — bookmark a folder and preview what's there, videos included. Nothing is copied until you say so.

Nothing to set up. Add a file and it lands where it belongs.

Then Categories — baskets that cut across every shelf. School. Work. Weekend chaos. A PDF, three notes and an HTML tool, together.

Press and hold any file to rename, share, categorise, or remove it.

LINKS BEHAVE THEMSELVES

Tap a link inside one of your pages and it opens in a private in-app viewer — no address bar, no history, nothing kept when you close it. Open it in your browser if you'd rather. Your library never turns into one.

ONE FILE HOLDS THE WHOLE NEST

Save everything as a single .bubohub backup — documents, shelves and categories in one portable file that belongs to you. New device, or just peace of mind: export it, bring it back whenever.

BUILT PROPERLY

Native on all three platforms. Real windows and right-click menus on Mac. Four themes, adjustable HTML zoom, search across the whole library. Available in 30+ languages.

QUIET BY DESIGN

No account. No sign-up. No ads. No analytics. Your documents are read on your device and stay there. Works with no signal at all.
