- **Visibility, position and sentiment:** See how often your brand appears versus competitors, where in the answer you are mentioned and how positively AI describes you.
- **Cited sources analysis:** Discover which domains, pages and publications the models reference in your category to find the content gaps worth filling.
- **AI crawler and traffic logs:** Track which AI bots visit your site, how frequently and which pages they read, closing the loop between publishing and AI visibility.
- **Score-based recommendations and content creation:** Get prioritised actions to improve your standing, then generate articles and pages designed to be understood and cited by AI.

**強み:** Covers the full loop from monitoring to cited sources to content actions; Covers a broad set of assistants including ChatGPT, Gemini, Claude, Copilot, Perplexity and Grok; Free initial analysis gets you a report without a credit card; MCP and API access to query your own data inside other AI tools

**制約・デメリット:** AI answer data is inherently volatile, so trends matter more than single snapshots; Full optimisation workflow requires a paid subscription and sends you into content production

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.

**制約・デメリット:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
