Practical overview
When it fits
Use Onebox when a task fits its built-in tools and you want to describe the desired result instead of finding and operating each utility yourself. For model-backed chat, account for the app's stated online connection to the chosen model.
Who it is for
- Android users who want to describe a task and have an in-app agent coordinate supported tools.
- People looking for image, document, bookkeeping and productivity utilities in the same app.
- Android developers exploring an Apache-2.0 Kotlin agent-and-toolbox project.
Documented uses
- Convert images into a PDF through an agent-directed tool workflow.
- Record information from a bill screenshot in a ledger.
- Create a to-do list from a request.
- Use image and document utilities without separately searching for each tool.
Requirements & limits
The README links to Google Play and the official website for international access, and lists Chinese app-store channels. It describes the F-Droid listing as in review. The project calls the app free and says users can bring an OpenAI-compatible API key, including keys with free tiers.
- The agent is described as invoking and chaining more than 90 in-app tools.
- The project distinguishes on-device local-tool execution from online conversation with the selected AI model.
- The README describes multiple mainstream models, custom AI engines and prompt management.
- The repository declares the Apache-2.0 license and identifies Kotlin as its primary language.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Guide limitations
- The documented Android targets are Compile SDK 37, Target SDK 37, and Min SDK 24.
