OneBox

OneBox is a free, ad-free all-in-one toolbox that packs 90+ carefully crafted tools into a single app, covering image processing, document work, AI assistance and everyday productivity.

【Why the name "OneBox"】
• One: all your everyday tools, in just one app
• Box: one box that holds them all
What it really aims for is not just "packing a lot in" — it's making sure you never have to switch to another tool app again.

【Productivity tools】
• Teleprompter, notepad, to-do lists, decision wheel
• Perpetual calendar, bookkeeping, cloud drive tools, habit tracker

【Files & PDF】
• PDF tools: merge, split, extract images and text
• Markdown editor with live preview
• File encryption, audio cover art extraction, image EXIF editing
• File browser and file transfer between devices

【Image tools】
• Crop, rotate, resize and convert formats (HEIC / WebP / AVIF and more)
• Filters, collage maker, long-image stitching, GIF tools
• QR code scanning and generation, color tools
• Image compression and format conversion — all processed locally, never uploaded

【Everyday gadgets】
• ID photos, network speed test, watermark camera
• Wish wall, time hourglass, Apk.1 installer
• Screen and media tools, plus mini-games for your spare time

【AI assistant: more than just a long feature list】
Plenty of toolbox apps can claim a long feature list. OneBox goes further with a built-in AI assistant — no more hunting for the right tool or memorizing steps. Just say what you need:
• "Turn this image into a PDF."
• "Add this bill screenshot to my ledger."
• "Make me a to-do list."
• "Check the stock market for me."
The AI understands, acts and reports back — all in one go.
• Chat with multiple leading AI models from a single entry point
• An AI Agent that can call the app's tools to get tasks done for you
• Writing, rewriting, summarizing and translation helpers
• Custom AI engines and prompt management

【An app that evolves on its own】
OneBox is not static. It runs an "AI self-evolution system":
You leave feedback → an AI analyzes it as a product manager → code is generated automatically → tested and shipped.
The bugs you report, the features you want, the polish you suggest — any of it may be evaluated and built by AI. In other words, OneBox fits your needs better the more you use it.

【Why OneBox】
• Free to use, no ads
• Privacy first: images and documents are processed locally on your device
• Clean, modern Material Design interface
• Constantly updated with new tools

"The last tool app you'll ever need" is an ambitious goal, but OneBox has already taken three key steps: bringing everyday tools into one place, making them effortless to use with AI, and letting real user feedback drive how the product evolves.

If you're tired of hopping between a dozen tool apps, give it a try — it might really become the last one you need.
