| Writesonic | Growth Radar | |
|---|---|---|
| Main job | AI visibility tracking alongside an AI writing platform | Ranks SEO and GEO fixes across several sites, ships them as pull requests, and grades the outcome |

| How a fix reaches your site | Not described in the pages checked | Opens a pull request on your repository, limited to an allowlist of paths. It cannot merge. |
| Grading a shipped change | Not described in the pages checked | Win, loss or flat 28 days after merge at a 10% threshold, then a second check that the lift is still holding |
| Google Search Console data | Not described in the pages checked | Yes. During early access it uses the operator's Google credentials |
| Price | Not checked; see the vendor's pricing page | Free during early access |
"Not described in the pages checked" means Writesonic's linked pages do not say. It is not a claim that the feature is missing.
