RankCLI vs Otterly.AI
Otterly.AI monitors brand mentions and citations across ChatGPT, Perplexity, Google AI Overviews and others for a set of prompts, and recommends content changes; it is a marketing team's monitoring product priced by prompt count. RankCLI audits the site itself: which crawlers get in, what the page declares, what blocks a citation before any prompt is asked, and it runs where developers work. A team that wants to know what the assistants say uses Otterly; a team that wants the site to be readable by them in the first place, and to keep it that way in CI, uses RankCLI. Many will use both.
| Aspect | RankCLI | Otterly.AI |
|---|---|---|
| What it is | An SEO and AI-search audit for developers: 280+ checks from the CLI, a GitHub Action with a CI gate, an MCP server for coding agents, and fixes as pull requests. It checks whether crawlers can read the site; it does not track what assistants say about a brand. | "AI Search Monitoring" for brands: tracks brand mentions, citations and sentiment across AI assistants for the prompts you choose, with recommendations. |
| Price | CLI, Action, MCP server and local fixes free forever. Hosted: Free (1 site weekly, 3 auto-fix PRs a month), Solo $9/mo, Pro $29/mo, Agency $99/mo. | Lite $29/mo (15 prompts, 3 recommendations a week), Standard $189/mo (100 prompts, API and MCP), Premium $489/mo (400 prompts, 10,000 GEO URL audits); +100 prompts $99/mo. The same page shows lower figures ($25, $160, $422) that read as annual pricing. |
| Free offering | The full audit of one page with every finding and no sign-up (rankcli.dev/free-audit), six free tool pages, the CLI with every check, and a Free hosted plan with a weekly audit and alerts. | A 7-day or 14-day free trial (the site states both), no card; a hub of free GEO tools (content GEO score, crawlability test, query fan-out simulator), a free email course and guide. |
| What it tracks | The site itself: crawler access fetched as each bot (search, AI search, user-triggered, training), metadata, structured data, sitemaps, Core Web Vitals, internal links, security headers; a score per category and the history of it. | Prompts: whether and how the brand is mentioned and cited per assistant, over time; AI search traffic analysis. |
| Fixes | Opens a pull request with the fix on a connected repository (the first one on the Free plan runs on RankCLI's own model key); local fixes with `rankcli fix`. | Recommendations (3 a week on Lite, unlimited above); no code changes. |
| CI and agents | `--fail-on` gate in the CLI and the Action, with baselines; Claude Code plugin, Codex, Cursor, ChatGPT through the MCP server; Astro, Nuxt, Next.js and Vite plugins audit the build output. | API and MCP access on Standard and above, for reporting; no CI gate. |
| Who it is for | Developers and the agencies who serve them; the Agency plan adds white-label reports and client links. | "Marketing teams", "agencies", "SMEs" and "solo marketers"; an agency partner program and a referral program. |
| Data | A weekly public dataset of the 400 most popular npm packages' sites (rankcli.dev/data/npm-sites), rebuildable from the public scripts. | Industry rankings, reports and GEO experiments published on the site. |
