Semrush alternatives: AI visibility tools, priced and compared
Semrush's AI Visibility Toolkit is the natural choice if you already live in Semrush. Teams look for alternatives when they need a dedicated tool that acts on what it finds, covers Copilot, or prices better across several brands.
Every fact below comes from each vendor's own pages, checked on 26 September 2026. Stellarcast is our product and appears in the list; we've kept every other entry to what its own site says.
Why teams look beyond Semrush
- A reporting add-on. It shows AI visibility beside SEO data but does not describe publishing fixes.
- No Copilot. The toolkit covers five engines; Microsoft Copilot is not among them.
- Per-domain pricing. $99 a month per domain adds up across brands or clients.
