Moz Domain Authority 31/100 vs category average 49 / leader 99 - limited third-party links, so AI systems rarely encounter mentions of the brand.
Ranked #2,124,935 on the Tranco list of most-visited sites - modest traffic makes the brand easy for AI models to overlook.
No Wikipedia presence was found - a major gap, since Wikipedia is among the most heavily weighted sources in AI training data.
The homepage meta description reads "To provide a free, open-source chemical process simulator with the rigor and capability of commercial tools, accessible to everyone." (No meta description) - this is the summary AI engines are most likely to quote.
Structured data on the homepage: canonical. Adding Organization and FAQ schema would further help AI crawlers parse the brand's identity.
AI-crawler access: No robots.txt found (default: all bots allowed, but explicit file preferred) - robots.txt controls whether engines like GPTBot and ClaudeBot can read the site at all.
Detected tech stack: ASP.NET, WordPress, Ghost.
Social footprint: verified profiles on GitHub, YouTube, X (Twitter), Facebook, Instagram; no detected presence on LinkedIn - consistent profiles reinforce the brand's identity across the web.
0 Reddit mentions - community discussion signals real-world reputation to AI models.
Live results from asking a general-purpose AI assistant about the brand, checked September 2026.

DWSIM scores 18/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
DWSIM has a weak AI-visibility profile at 18/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (27/100) and its weakest is trust (12/100). It benefits from a Wikidata knowledge-graph entry, a global traffic rank of #2,124,935 (Tranco) and open access for AI crawlers (GPTBot, ClaudeBot, etc.). The main gaps holding it back: no clear Wikipedia entity to anchor it in LLM training data, a low Moz Domain Authority of 31/100 and thin schema.org structured data. In a live check, Claude could already identify DWSIM from memory (September 2026) - a sign these signals are paying off.
The score combines seven dimensions - name quality, digital presence, visual identity, messaging clarity, trust foundation, AI discoverability, and brand authority - into a single objective benchmark.
