What Is Semji and What Does It Do?

Updated

Semji is an agentic AI platform for content optimization across both AI search and Google. It finds GEO (generative engine optimization) and SEO opportunities, writes the page, and sends it to your CMS — then measures whether AI platforms actually mention and cite you. It's built for marketing teams and content strategy leads who need to show up in AI answers, not just rank in blue links.

The core problem Semji addresses

AI assistants like ChatGPT, Gemini, Perplexity, and Google AI Overviews increasingly answer questions directly, often without linking to the sources that informed them. A page can rank well on Google and still never be named in an AI answer. Semji targets that gap: it tracks whether your brand appears in AI-generated responses and turns the misses into content briefs.

What the platform actually does

The workflow runs in three stages, per Semji's own description:

  1. Find opportunities — The Intelligence Hub · GEO scores your mention rate, citation rate, and average position on the questions ChatGPT and Gemini answer without citing you.
  2. Create the content — Semji writes the page for the opportunity it identified.
  3. Publish — It sends the finished page to your CMS.

Alongside GEO, the platform covers traditional SEO reporting, content ideas, pages, planning, and performance, plus agents, brand voice, a knowledge base, and integrations.

The metrics it tracks

Semji's AI Visibility dashboard reports these numbers over a rolling window (the demo shows 90 days, updated weekly):

Metric What it measures
AI Visibility Score Composite score, benchmarked against tracked competitors
Mention rate Share of tracked prompts where your brand is named
Citation rate Share where you're linked as a source, not just named
Avg. mention position Where you appear in the answer (lower is better)

Scores can be broken down by platform — the demo shows ChatGPT, Google AI Overviews, Perplexity, Gemini, Claude, and DeepSeek — and compared against a market average and named competitors.

Who it's for

Semji positions itself for marketing teams and content strategists at scale. Its customer list includes Allianz, Otto, Reitmans, Randstad, PCMag, Mashable, and Christie's International Real Estate, and the site cites +500 companies across 175 countries and 25+ languages. If your job includes deciding what content to produce and proving it drives visibility and revenue, that's the intended user.

Results customers report

Semji publishes customer-supplied figures from its case studies:

  • Groupe SEB: +228% monthly conversions from optimized content; +165% SEO revenue on covered categories
  • Macif: +89% non-brand SEO traffic in 12 months

These are the customers' own numbers, so treat them as illustrative of what's possible rather than guaranteed outcomes.

How to evaluate it for your team

  • If AI visibility is a real channel for you — you sell in categories where buyers ask ChatGPT or Gemini for recommendations — the mention/citation tracking is the differentiator worth testing.
  • If you mainly need classic SEO tooling — keyword research, rank tracking, backlinks — Semji's pitch is narrower and you may already have coverage.
  • If you want to try before committing — Semji offers a free GEO audit with no signup required, reporting results in about 2 minutes. That's the lowest-effort way to see whether your brand is being cited in AI answers today.
  • If you need pricing or plan details — check the Pricing and Plan pages directly; the site links to both but doesn't publish figures in the material available here.

The clearest first step is the free GEO audit: it tells you whether the problem Semji solves is actually your problem before you talk to sales.
