SemanticOS automates topical map creation, generates Koray-compliant content briefs, and gives you 70+ semantic SEO tools — all in one platform built on entity-based SEO principles.
No spreadsheets. No manual clustering. No guesswork.
Type your domain or seed keyword. Tell SemanticOS your entity type, audience, and target market. That’s all the input you need — no technical setup, no onboarding calls.
SemanticOS analyzes entity-attribute relationships, keyword clusters, and SERP intent to generate a complete pillar–cluster–supporting architecture with Koray-compliant briefs for every article.
Export to Google Sheets, Notion, or PDF. Track entity drift, detect cannibalization, monitor E-E-A-T signals, and use 70+ tools to close every semantic gap until you dominate your niche.
SemanticOS is the only semantic SEO tool that automates topical map building from scratch. Enter your domain, define your entity, and the AI constructs a full pillar–cluster–supporting architecture aligned with how Google models topical authority.
Input your domain and business context. SemanticOS analyzes your niche, entity type, and competitive landscape to generate a semantically complete topical map structured around entity-attribute relationships.
Every map follows a strict three-tier structure: pillar pages establish authority, cluster articles cover intent variations, and supporting content closes semantic gaps — mirroring Google’s entity model.
Visualize coverage on a live heatmap — which attributes are covered, which are thin, which articles compete for the same intent. Fix gaps before they cost you rankings.
SemanticOS generates Koray-compliant content briefs that tell writers exactly what to cover, how to structure it, and which entities to include — not just a keyword list.
| H1 | Espresso brewing: complete guide | entity:espresso |
| H2 | What is espresso? (definition) | attr:definition |
| H2 | Espresso machine attributes | attr:hardware |
| H3 | Pressure (9 bar standard) | val:9bar |
| H3 | Boiler types: single, dual, heat-exchange | val:boiler |
| H2 | Grind size and dose ratio | attr:grind |
| H2 | Related: ristretto, lungo, americano | rel:variants |
Every brief includes a semantically ordered heading hierarchy — central entity, attributes, related entities, question-based sub-topics — structured to match how Google reads a comprehensive article.
SemanticOS checks SERP intent signals before generating a brief. If two articles compete for the same query, it flags the conflict and recommends consolidation or redirection — saving you from cannibalization before it happens.
Turn any brief into a full draft. SemanticOS injects NLP-confirmed semantic terms, entity co-occurrences, and contextual phrases at the right density — natural reading, full signal coverage.
Google’s ranking model is built on entities, not keywords. SemanticOS gives you the tools to define, build, and protect your entity identity across your entire site.
| kind | key | meta | value |
|---|---|---|---|
| entity | Espresso machine | type | product |
| attribute | pressure | unit | bar |
| value | 9 | confidence | 0.97 |
| attribute | boiler_type | unit | enum |
| value | dual | confidence | 0.91 |
Map every entity your site claims to be about — its attributes, values, and relationships. The EAV structure becomes the backbone of your topical map, internal linking, and schema markup.
Close the gap between claimed and perceived identity. Entity Drift compares what your content claims versus what Google’s entity model assigns, then surfaces the exact articles causing misalignment.
Build structured author profiles, credential pages, and organization schema that demonstrate real Experience, Expertise, Authoritativeness, and Trustworthiness — the signals that decide high-stakes queries.
SemanticOS replaces the fragmented stack most SEOs use. Everything is connected — your topical map drives your briefs, your briefs drive your audits, your audits update your map.
Reverse-engineer competitor topical maps. See which entity clusters they dominate and which gaps they left open.
Apply entity SEO principles to your GBP listing. Align profile attributes with what Google expects for your category.
Connect Search Console to track Pillar Page Rank — a composite authority score per cluster based on impressions, clicks, position trends.
Measure how semantically close any two pieces of content are. Confirm internal links make semantic sense before publishing.
Generate topical maps and briefs in 15+ languages, with entity-attribute structures adapted for regional search intent — not just translated.
Design entity-driven programmatic templates at scale. Define entity, attributes, and pattern once — generate thousands of unique pages.
Most SEO tools treat semantic SEO as an afterthought. SemanticOS is purpose-built on entity-based, Koray-compliant principles — giving you depth no general tool can match.

Replaced our $4k/mo SEO consultant in week one. The Koray-compliant briefs alone are worth the subscription.
Finally a tool that understands SEO is about entity structure, not keyword density. The EAV output is genuinely novel.
We shipped 60 articles last quarter, all briefed by SemanticOS. Traffic is up 240% YoY and entity drift is at zero.
Every plan includes the core topical map builder and brief generator. Cancel anytime.
For solo SEOs starting their first topical map.
For SEOs and content teams who need the full entity stack.
For agencies managing multiple client sites at scale.
SemanticOS exists because I got tired of SEO tools that chased keyword density while Google had already moved to entity-based search. I spent years studying the Koray SEO framework — how Google’s Knowledge Graph models topics, entities, and their attributes — and realised there was no platform that actually operationalised it for practitioners.
So I built one. SemanticOS is the tool I needed when I was manually constructing topical maps in spreadsheets at 2 a.m. Every workflow in the platform comes from real SEO work: the topical map builder, the EAV architecture generator, the entity drift analyser, the E-E-A-T credential system — all of it. No bloat, no buzzwords. Just the frameworks that produce durable rankings.
If you’re serious about topical authority, I built this for you.
