Rank #1

Letter

A coding agent for growth engineering that measures how AI answers name and cite you, then fixes and builds your site through pull requests.

8.4/10
Checked
Verdict: The pick for developers and agent-driven teams: the only tool here that measures, then ships the fix as a pull request your own agent can drive. For a no-code dashboard, Peec AI or Otterly.AI fit better.

What it does

Letter (from The Letter Company) asks AI answer engines the questions you care about and records how often the answers name or cite your brand against competitors (share of voice). Its Visitors script and server snippet show the AI agents and crawlers reading your site and the visits that arrive from AI answers. Letterpress-1 then turns what it finds into work: it fixes issues on your marketing site, builds pages such as comparisons and answers, and opens each change as a pull request with a live preview, so nothing ships until you merge it. Everything in the app is also exposed through an API, a CLI and an MCP server, so Claude Code, Codex or your own agent can run the same tools.

Who it suits

Developers, founders and agent-driven teams who want API and MCP access and want the fixes shipped as pull requests, not just reported.

Who should skip it

You want a no-code dashboard for a marketing team to watch share of voice, with no one to review pull requests.

Strengths

  • API, CLI and MCP on every plan; your own agent gets the same tools as the app
  • Acts on findings: site fixes and new pages arrive as pull requests with previews
  • Sees both sides: AI answer probes plus AI crawler visits and click-throughs on your own site
  • Usage pricing published to the token, from $25 a month, with free tokens to start

Limits

  • Built around a git repository; teams without one get less from it
  • Its list of answer engines probed is not on its pricing page
  • Less of a point-and-click reporting dashboard than Peec AI or Otterly.AI
Cost
From $25/month (Hobbyist, 2,500 tokens) to $2,500/month (Scale); Enterprise $10,000/month. Each AI visibility answer read costs 12 tokens. Every account starts with 1,000 free tokens, no card.
Engines
Not listed on the pricing page. Check the API docs at app.letterstory.com/docs/api or ask Letter which engines its probes cover.
API and MCP
API, CLI and MCP on every plan, able to read data and start changes (pull requests).
Sources
Pricing · Product overview · API docs · agents.md

Criterion scores

  • Tracks named and cited rates and share of voice on its own questions, plus AI crawler visits and click-throughs from AI answers on your site.
  • The engines its probes cover are not published on the pricing page, so it scores as an unpublished list.
  • API, CLI and MCP are on every plan and can start work, not only read it.
  • Every plan, per-token rate and overage is published; self-serve start with free tokens.
  • Actionability 20%10/10
    Opens pull requests that fix the site and build pages, each with a preview for review.
  • Share of voice is computed from the probe answers it reads; check in a trial how much of each raw answer and its sources you can open.
Rank #2

Ahrefs Brand Radar

AI visibility from a large index of prompts plus your own tracked prompts, inside the Ahrefs SEO suite.

8.3/10
Checked
Verdict: The strongest research tool for teams already on Ahrefs; pair it with something that does the fixing.

What it does

Brand Radar measures how brands appear in AI answers from two sources: an index Ahrefs says holds 558M+ prompts, and custom prompts you track yourself. It stores the responses it reads and shows each tracked prompt's answer with its mentions and citations. Ahrefs adds fan-out queries for content gaps, citation opportunities, research on YouTube, Reddit and TikTok sources, Bot Analytics (in beta) and AI traffic in its Web Analytics.

Who it suits

SEO teams already on Ahrefs who want AI visibility next to their search data, with a market-wide index for research.

Who should skip it

You want a tool that changes your site or writes the content for you; Brand Radar points to gaps, you do the work.

Strengths

  • Market-wide prompt index plus your own custom prompts
  • Stores every response; answers, mentions and citations per prompt
  • Seven engines including Claude on custom prompts
  • Public pricing, with some prompts included in paid Ahrefs plans

Limits

  • Full engine coverage costs more ($699/month for all models on custom prompts)
  • Not verified whether Ahrefs' MCP server covers Brand Radar data
  • Finds opportunities; doesn't make the changes
Cost
Custom prompts from $50/month, or $699/month for all models; AI Visibility Index $199/month. Paid Ahrefs plans include some daily prompts (Lite: 5). Check ahrefs.com/brand-radar for the current tiers.
Engines
Index: Google AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini, Copilot. Custom prompts add Claude.
API and MCP
Ahrefs API and an official SEO MCP server on paid plans; coverage of Brand Radar data not verified.
Sources

Criterion scores

  • Mentions, citations and competitor share across an index and your own prompts; Bot Analytics and AI traffic on the Ahrefs side.
  • Seven engines across index and custom prompts; full model coverage is a higher tier.
  • Official API and MCP exist on paid plans; whether they expose Brand Radar is not confirmed.
  • Prices are published per tier with per-check overage.
  • Content-gap fan-outs and citation opportunities, but no changes made for you.
  • Ahrefs says it stores every response and shows the answer, mentions and citations per prompt.
Rank #3
