AIX Universal Markdown · v0.1.3 Draft
Validate before you ship.
Every chatbot produces different markdown. None of them agree on heading hierarchy, bullet markers, table format, or what survives a copy operation. AIX is the open standard for what AI-generated markdown must emit, render, and round-trip without loss.
The Markdown Problem
Same prompt. Four chatbots. Seventeen formatting dimensions of disagreement.
Markdown is the most widely used lightweight markup format on the web — and the most fragmented. Twenty-two years after John Gruber introduced it on Daring Fireball, no two parsers agree on how to interpret it, no two platforms agree on which extensions to support, and as of the AI era, no two generators agree on how to produce it.
We fed the same prompt to Claude, ChatGPT, Gemini, and Perplexity, asking each for a structured response with paragraphs, bullet lists, and a comparison table. The outputs differed on seventeen separately measurable formatting dimensions. Heading style. Bullet markers. List spacing. Section separators. Table cell encoding. One chatbot’s table didn’t even survive the copy operation — it existed on screen and not in the clipboard.
Every prior markdown standardization effort has been about parsers: given a markdown file, what HTML should come out. CommonMark and GitHub Flavored Markdown answer that question rigorously. But the question of what markdown an AI tool should emit in the first place — and what an interface must preserve as it renders and copies — has never been specified. That seat is empty.

The Evidence
How four chatbots format the same data.
Below are excerpts of how Perplexity, Gemini, ChatGPT, and Claude formatted a single item in a five-platform comparison. Same prompt. Same data. Four house dialects.

The Architecture
Three layers. Three failure surfaces. Three fixes.
Variance between AI markdown outputs lives in three distinct places. AIX Universal Markdown specifies normative requirements at all three.
What the AI model emits as raw markdown. Failure mode: heading inconsistency, escape sequences, invisible characters, non-canonical separators. Fixed by prompt engineering, fine-tuning, and model-side conformance rules.
How the chatbot’s UI displays the markdown. Failure mode: lossy transforms — glyph substitution for cell values, structural elements rendered as components that can’t serialize back to markdown. Fixed by the platform vendor.
What survives a clipboard or export operation. Failure mode: silent loss of structural elements. The most damning kind of failure — the user has no way to know what was dropped. Fixed by vendor preservation guarantees and the AIX Markdown Cleaner as consumer-side defense.
The Toolkit
Two tools. One spec. Open source.
For developers · The reference tool
AIX Validator
Paste any AIX envelope or AIX Universal Markdown document. Get a verdict against all six validation tests — heading hierarchy, bullet consistency, list spacing, table conformance, special characters, round-trip integrity. Specification rendered inline as reference.

Markdown Cleaner
Paste whatever a chatbot put on your clipboard. The Cleaner normalizes heading style, bullet markers, list spacing, table format, and special characters into AIX-conformant output. It also flags what may have been dropped during the copy operation.

SoloTrillion.io is the wedge.
AIX — the AI Interchange Standard authored by Michael Tchong at Ubertrends LLC — defines the envelope, naming convention, persona registry, task schemas, and provider comparison format for an interoperable generative AI ecosystem. The full standard lives at aix-standard.org. This site is its developer-facing wedge: a Validator and Cleaner you can run in thirty seconds, plus the Markdown subset of the spec rendered inline.
The Solo Trillion Orchestra applies AIX across an entire agent system — platform-level orchestration with AIX as the wire format between every component. Same standard, expanded to platform scope.
AIX helps your output survive the trip between tools — a much-needed open standard for generative markdown, data, and agent workflows. Keeps every heading, table, and field intact from one tool to the next, so you render once and never re-fix the same output by hand.
