II-Agent is an open-source intelligent assistant designed to streamline and enhance workflows by independently executing complex tasks across multiple domains. It features a chat interface that integrates various AI models like Gemini, Sonnet, and GPT, allowing users to connect their own API keys and utilize advanced tools such as Claude Skills and GPT-5 Code Interpreter.

II-Agent is an open-source assistant from Intelligent Internet. The README frames it as moving from passive tools to systems that carry out complex tasks on their own. It lists three headline abilities: full-stack development from scaffolding to deployment, slide creation from short briefs, and deep research through II-Researcher, a companion research agent.

The README also describes II-Agent Chat, which lets you work across several models and tools in one place. The web-hosted version at agent.ii.inc comes with Gemini 3, Sonnet 4.5 and GPT-5 ready to use, and you can connect your own API keys, switch models inside one thread, and use Claude Skills, GPT-5 Code Interpreter and text file search alongside them. The README has a SWE-Bench Pro section heading, but the figures are not in the text we have.

The README itself is short. For installation it points to an external official guide, with an installation video. The badge shows Apache 2.0. Last push was 2026-08-16. This review is based on the README and repository data; we have not run it ourselves.

Features

01Full-Stack Development: Complete web app scaffolding and iterative development with intelligent code generation and optimization.

02Slide Creation: Transform short briefs into polished presentations with intelligent content structuring, design suggestions, and automated formatting.

03Deep Research: Comprehensive research capabilities through tight integration with II-Researcher, enabling thorough investigations, data analysis, and detailed report generation.

Why choose it

+One agent for web app development, slide decks and deep research

+Open source under Apache 2.0, with a hosted web version for trying it first

+Chat mode switches between models in one thread and supports your own API keys

+Companion II-Researcher agent handles the research workflow

Trade-offs

!The README is thin: install steps and benchmark details are left to external pages

!A broad general-purpose scope means each task type may be less polished than a specialised tool

!Running code-writing and deploying agents needs sandboxing and your own judgement on what they may touch

!The hosted version sends your prompts to the service, so use self-hosting for sensitive work
