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).
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.
