Onto is an innovative edge-first infrastructure layer designed to optimize your website's readability for AI agents. By extracting semantic substance into compact Markdown payloads, Onto ensures efficient content delivery to AI agents via HTTP content negotiation, while maintaining a full HTML experience for human users. This approach significantly reduces payload size, with potential reductions of 10-100x, and minimizes edge routing latency to under 15ms.

While the full Onto SDK and Edge Middleware are currently in private beta, today we are launching our core diagnostic tool: The AIO (Agent Input Optimization) Score Calculator.

The Problem: The "React Tax"

The web is experiencing a fundamental platform shift. AI agents—from coding assistants like Cursor to shopping bots and search engines like Perplexity—are the new browsers.

But the modern web is optimized for human eyeballs and adtech, not LLMs. Most production React/Next.js apps ship megabytes of HTML, CSS, JavaScript, and layout wrappers. When an AI crawler ingests your pages, it burns through token budgets parsing Tailwind classes and nested <div> tags instead of your actual business-critical text.

We call this the React Tax. And it carries real business risks:

• E-Commerce: AI shopping assistants hallucinate discounts, misstate inventory, or misrepresent shipping policies.

• SaaS & Open Source: Coding agents fail to pull your latest API contracts, falling back on outdated forum snippets.

• Infrastructure: Massive payload bloat leads to slow ingestion, and aggressive bot traffic gets blocked by WAFs, leaving your site entirely omitted from AI-driven discovery.

The Solution: Separate Presentation from Semantics

We believe you shouldn't have to build a "shadow web" or maintain two codebases just to ensure Claude, ChatGPT, and Perplexity understand your product.

Onto’s core philosophy is that web presentation and semantic meaning must be cleanly separated. We act as a negotiation layer between your rich component trees and the AI intermediaries that increasingly dictate user journeys—serving beautiful React to humans, and pure, structural Markdown to machines.

Launching Today: The AIO Score Calculator

Before you can fix how AI perceives your website, you need to know what models are actually seeing when they scrape your domain.

Drop your URL into the AIO Score Calculator, and our engine will perform a dual-fetch simulation (one as a standard Chrome browser, one as an AI Agent) to evaluate your site's readiness for the agentic web.

Your free audit will reveal:

• Your React Tax: The exact ratio of your total HTML/JS byte bloat compared to your visible semantic text.

• Semantic Richness: How well your site leverages <main>, <article>, tables, and JSON-LD schema to guide machine readers.

• Content-Negotiation Readiness: Whether your infrastructure currently detects AI bots and serves optimized payloads.

See Your Score & Join the Future

Stop letting LLMs guess what your website is about. Run your domain through the AIO Score Calculator to see your bottlenecks, and join the exclusive waitlist for the full Onto SDK to instantly fix your AI readability.
