About Aiia Harness
Aiia Harness is a browser-based AI agent workspace where every capability — models, tools, skills, and delegation — is a plugin. It is built on a vendored Cordis core and is available at aiia.ro.
What is an AI agent harness?
An AI agent harness is a platform that runs AI agents with real tool access: it lets an agent read and edit files, run shell commands, search the web, delegate to subagents, and follow skill playbooks — and it exposes all of that in a browser workspace instead of a terminal.
Key capabilities

| Plugin architecture | Every capability (models, tools, skills, UI) is a swappable plugin on a vendored Cordis core. |

| Browser-native | Multi-session workspace with settings, model picker, and history — no terminal required. |
Why "everything is a plugin"
Most AI tools are closed one-trick ponies. Aiia Harness treats every capability as a replaceable plugin: swap the model, add a tool, install a skill, or change the UI — without forking the product. That makes it inspectable, customizable, and future-proof as the agent ecosystem evolves.
Who it is for
Technical founders, developers, and technical marketers who want a controllable workspace where an AI agent can finish whole tasks — coding, research, content, and marketing operations — instead of juggling five separate AI tools.
Status & access
Aiia Harness is an early (0.1-era) release. Access on aiia.ro is currently invite-only. Request access from the app at aiia.ro. The software is also self-hostable for teams that want full control.
Frequently asked questions
Is Aiia Harness a chatbot?
No. It is an agent harness: the agent has real tool access (files, shell, web search, subagents) and can complete work end-to-end, not just answer questions.
Do I need to use a terminal?
No. The workspace is browser-native. You can run shell commands through the agent if you want, but nothing requires a local terminal.
What models does it use?
Aiia-V4-Flash and Aiia-V4-Pro, both with a 1,000,000-token context window. Because models are plugins, more can be added.
What are the 49 marketing skills?
Skill playbooks from the open-source marketing-skills.com pack (coreyhaines31/marketingskills): SEO audits, AI search optimization, CRO, copywriting, content strategy, launch, PR, directory submissions, pricing, offers, analytics, and more.
Is my data safe?
Agents run in sandboxed per-user environments; shell commands execute in isolated remote boxes. See the app for current privacy guidance.
