OneBox is a free all-in-one toolbox: open 100+ file formats directly, with 90+ tools for images, PDFs, files and everyday life — plus a real AI assistant that doesn't just answer questions, it uses the toolbox for you.

【AI chat, with the models you choose】
• One entry point for mainstream models: OpenAI GPT, Claude, Gemini, Grok, DeepSeek, Qwen, OpenRouter
• Third-party friendly: plug in any OpenAI-, Anthropic- or Responses-compatible API with your own key — even a local model running on your own computer
• Voice input, image and file attachments, streaming replies, prompt library
• Writing, rewriting, summarizing and translation help
• AI content detector: check whether a piece of text or an image was AI-generated

【An agent that actually does the work】
• The assistant calls 70+ tools inside the app: image compression and format conversion, PDF merge and split, OCR and barcode reading, EXIF editing, watermarks, bookkeeping, to-dos, notes, cloud drives, web search and page reading
• It can work your phone too: see the screen, tap, swipe and type to finish a task in another app
• A built-in browser it can drive: open pages, read content, run scripts
• Agent memory and skills: it remembers your profile and how you like things done

【Describe it — the app builds it】
Stop hunting through menus. Say what you want and OneBox turns it into a working tool or app:
• "Give me 8 candidates for what to eat today." — AI create on the decision wheel fills in the options for you
• "Travel planner." "Article style converter." — AI builds the whole app, screens and tools included; refine it by chatting: "change the button to blue, add a date picker"
• Answers arrive as real controls — forms, sliders, date, time, color and file pickers rendered natively in the chat, not a wall of text
• Generate images from a text prompt, then edit, compress or convert them with the same toolbox
• Every tool that needs input has an AI create entry: describe it, and the AI writes it for you

【Open 100+ file types】
• Open files directly from chat attachments, shares from other apps, or your file manager
• Handle common Word, Excel, PowerPoint, PDF, EPUB, image, text and code, audio and video, and ZIP formats without installing separate viewers for each type

【The toolbox, for when you'd rather tap】
• Images: a full photo editor — crop, filters, collage, long-image stitching, GIF, Image Studio with layers, brushes and text — plus format conversion (HEIC / WebP / AVIF), an image compressor, bitmap-to-SVG and a gradient wallpaper maker, all local
• Files & PDF: document scanner, PDF merge and split, extract text and images, Markdown editor with live preview, file encryption, EXIF editing, device-to-device transfer
• Productivity: teleprompter, notepad, to-dos, bookkeeping, habit tracker, calendar, decision wheel, record center with AI insights (health, items and expiry, period)
• Everyday: password vault, ID photos, QR code scanner and generator, speed test, watermark camera, unit converter, loan calculator, compass and altimeter, ruler and protractor, LED marquee, color picker, dead pixel test, dice roller, Text Card, I Ching divination, mini-games
• Ad Watch: watch a rewarded ad to earn AI points — your call, never forced

【Also inside】
• DSH client: pair with DeepSeek Harness on your computer over an encrypted relay, drive it from your phone
• OneBox even evolves on its own: your feedback is read by an AI product manager, then coded, tested and shipped

【Why OneBox】
• Free to use, no forced ads — rewarded ads are optional and earn AI points
• Privacy first: images and documents are processed locally on your device
• Clean, modern Material Design interface
• New tools and AI features keep landing

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