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

Build a SaaS with AI

AI tools can generate a full SaaS in hours. The resulting app often works — but it is invisible. No metadata, no schema.org, no sitemap, no trust pages. Technically deployed. Digitally absent.

The problem

When you build with Cursor, v0, Bolt, or another AI code tool, the focus is on making the product work. The existence layer — metadata, Open Graph, schema.org, robots.txt, sitemap, trust pages — is not generated by the AI. It is left as a gap.

A deployed SaaS with no title tag, no meta description, and no Open Graph will not be shared correctly on social platforms, will not be understood by AI agents summarizing the web, and will not rank for any search terms related to what it does.

How Existence Compiler helps

Paste the URL of your deployed SaaS. Existence Compiler crawls the live site, identifies every gap in the existence layer, and produces a Fix Pack with ready-to-paste snippets. No manual HTML inspection required.

Technical layer

Title, canonical, meta description, robots.txt, sitemap.xml

Social layer

Open Graph tags, Twitter Cards, preview image check

AI readability

schema.org markup, llms.txt, structured data

Trust layer

Presence of /about, /privacy, /terms, security headers

Example scenario

Typical AI-built SaaS audit

·No title tag or generic framework default ("Vite App", "Create React App")
·No meta description
·No Open Graph — social shares show blank cards
·No schema.org markup
·No robots.txt or sitemap.xml
·No /about, /privacy, or /terms pages
·Digital Existence Score: 8–15 / 100

What this does not promise

Closing the existence gaps improves the technical conditions for discovery. It does not guarantee indexing speed, traffic volume, or conversions. The Fix Pack should be reviewed before implementation — AI-generated suggestions are a starting point.
