What is Existence Compiler?

It is an analysis system that takes your project URL and returns a Digital Existence Score plus an actionable report. It evaluates technical presence, semantic clarity, AI readability, trust signals, and distribution readiness.

What is the Digital Existence Score?

It is a score from 0 to 100 calculated by deterministic rules. It measures how detectable, understandable, and shareable your project is for search engines, AI agents, and social platforms.

Does it guarantee traffic, sales, or indexing?

No. Existence Compiler diagnoses technical and semantic gaps. Improving those conditions increases the likelihood of being discovered, but does not guarantee specific outcomes.

Which pages does it analyze?

In the current MVP it analyzes the main page of the URL you provide, plus checks for common pages such as /about, /pricing, /faq, /contact, /docs, /changelog, /security, /privacy, and /terms.

Yes. The Free plan is completely free and requires no account. You can analyze any URL and download the report in Markdown or JSON.

Does it store my data?

Existence Compiler stores minimal analysis metadata server-side to enable before/after comparisons, such as URL, score, timestamp and a compact report summary. Shared reports are stored with a 30-day TTL. It does not store raw HTML, full page text, raw schema dumps or unnecessary crawl payloads. No account is required for the free analysis flow.

Does it work with SPAs or React/Vue/Angular apps?

The analysis may be incomplete for JavaScript-rendered apps. The crawler fetches the initial HTML without executing JavaScript, so metadata injected only at runtime may not be detected.

It is a simple text file that helps AI systems understand what your project is and how to reference it. Existence Compiler generates a ready-to-use llms.txt snippet based on your detected content.

Does it use AI for analysis?

The main analysis is deterministic (rule-based). An optional AI enhancement layer can generate a deeper semantic summary if enabled, but the core report and score do not require it.

Use Case

Turn an idea into an MVP

You have an idea. Maybe a domain. Maybe a rough landing page. But without a structured existence layer, no search engine, AI agent, or person landing on your page can understand what it is.

The problem

A raw domain with no title tag, no meta description, no schema.org, and no Open Graph scores effectively zero for any crawler, AI agent, or social platform. The idea exists in your head. The product does not yet exist digitally.

Most founders focus on building features before establishing the existence layer. By launch day, the product is technically built but digitally invisible.

How Existence Compiler helps

Paste your URL — even an early draft or a competitor’s site as a reference. Existence Compiler audits the page, calculates a Digital Existence Score across five dimensions, and produces a structured Fix Pack with ready-to-paste code:

·Title tag and meta description with specific copy suggestions
·Canonical URL
·Open Graph and Twitter Cards
·schema.org WebApplication or WebSite markup
·robots.txt and sitemap.xml
·llms.txt for AI readability
·Recommended internal pages: /about, /pricing, /faq

Example output

Score before / after

A raw domain with no metadata typically scores 4–12 / 100. After applying the Fix Pack — title, description, canonical, Open Graph, schema.org, robots.txt, sitemap — the same domain typically reaches 58–68 / 100 before a single line of product code is shipped.4–12 / 100

What this does not promise

Existence Compiler improves the technical conditions for discoverability. It does not guarantee traffic, indexing, or sales. The Fix Pack is a starting point that should be reviewed and adjusted for each project.
