Keyword.com (formerly Serpbook) is a rank tracking platform founded in 2014. Keyword.com has been in the search tracking space for over a decade and has added an AI Visibility module that tracks brand mentions across 9 AI engines. Keyword.com brings its experience in traditional search ranking to the AI visibility space, offering the AI module as an add-on to its existing rank tracking platform or as a standalone purchase.
If you're evaluating AI visibility tools, here's a detailed breakdown of how Keyword.com works, what Keyword.com costs, and how Keyword.com compares to Mentionable.
How does Keyword.com track AI visibility?
Keyword.com's AI Visibility module monitors brand mentions across 9 platforms: Google AI Overviews, Google AI Mode, ChatGPT, Gemini, Perplexity, Copilot, DeepSeek, Mistral, and Claude. Users set up prompts (keywords or queries), and Keyword.com checks whether the brand appears in AI-generated responses across selected engines.
Keyword.com's citation tracking identifies which pages and sites get cited in AI answers. This helps users understand what content is driving their AI visibility. Keyword.com's competitive analysis compares visibility and citations against competitors, showing where competitors are winning and where gaps exist.
Keyword.com includes brand sentiment analysis that monitors whether mentions are positive, negative, or neutral. Keyword.com's Google AI Overviews tracking shows when AIO appears for keywords and which URLs are cited.
Keyword.com uses a credit-based system where each refresh consumes credits per engine: 0.25 credit per prompt on AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Copilot, 1 on DeepSeek, 2 on Mistral and 3 on Claude. Users can schedule manual, hourly, daily, or weekly updates. Tracking across all 9 engines consumes credits faster than tracking a single engine.
How much does Keyword.com cost in 2026?
Keyword.com AI Visibility starts at $9.80/month ($7.83 billed annually) for 20 credits, with tiers of 20, 50, 100, 200, 500, 1,000 and 2,000 credits. The AI module is sold standalone or included in Keyword.com's 360° Visibility plans, which start at $26/month and include 15 to 250 AI credits. A 14-day free trial is available, no credit card required.
Credits reset monthly and don't roll over. Each engine consumes credits separately (Claude costs 12 times more per prompt than ChatGPT), so tracking across all 9 engines depletes the allocation faster than tracking a single engine. The effective monthly cost depends heavily on how many engines are tracked and how often refreshes are scheduled.
| Aspect | Keyword.com | Mentionable |
|---|---|---|
| Starting price | $9.80/month (20 credits) | €79/month (Growth, up to 115 prompts) |
| Pricing model | Credit-based (per engine, per refresh) | Fixed monthly price with a credit pool (1 credit per scan, 15 on Claude) |
| LLMs covered | 9 | All 7 (included on every plan) |
| Cost predictability | Variable (depends on usage) | Fixed monthly price, overage capped by a spending limit you set |
| Free trial | 14 days | 7 days, no credit card |
Light users who track a few prompts on one or two engines may find Keyword.com's credit system affordable. Heavy users tracking across all 9 engines with frequent refreshes could burn through credits quickly.
What does Keyword.com do well?
Keyword.com's $9.80/month entry price is one of the lowest starting points for AI visibility tracking. For brands testing whether AI visibility monitoring is worth the investment, Keyword.com removes the cost barrier.
Keyword.com's 14-day free trial lets users test the platform before committing money. Most enterprise AI visibility tools either don't offer trials or require a sales process to get started.
Keyword.com has been in the search tracking space since 2014. Keyword.com's longevity and rank tracking expertise give it credibility, and its infrastructure is mature. Keyword.com is not going anywhere.
Keyword.com's 9-engine coverage is broad. Google AI Overviews, Google AI Mode, ChatGPT, Gemini, Perplexity, Copilot, DeepSeek, Mistral, and Claude cover a wide range of the AI search landscape. For users already tracking Google rankings with Keyword.com, having AI visibility in the same dashboard is a practical advantage.

Why choose Mentionable over Keyword.com?
Keyword.com is a rank tracker first, with AI visibility added as a module. Mentionable is built from the ground up for AI visibility tracking. If AI search performance is your primary goal, Mentionable provides a more focused and predictable experience.
- Fixed monthly price, capped overage. Keyword.com uses credits that deplete faster when tracking multiple LLMs. Every Mentionable plan is a fixed monthly price with a credit pool: Growth includes 1,500 credits, enough for up to 115 prompts across all 7 AI engines, and any overage is capped by a spending limit you set. Agency is €299/month with 5,000 credits, unlimited projects, and all 7 AI engines.
- No per-engine credit math. Keyword.com charges a different credit cost per engine (0.25 credit per prompt on most engines, 3 on Claude). On Mentionable, a scan costs 1 credit on every engine except Claude (15 credits), and the Growth pool of 1,500 credits covers up to 115 prompts across all 7 AI engines.
- Automatic prompt generation. Keyword.com requires manual prompt setup. Mentionable scans the user's URL and suggests up to 40 relevant prompts, eliminating the research step.
- Page generation and AI traffic analytics. Mentionable writes the missing page for prompts where AI engines answer without mentioning you (150 credits), and its Google Analytics 4 integration shows which AI sources actually send visitors.
- AI assistant in the dashboard. Every Mentionable plan includes an AI assistant. You ask a question in plain words, such as why a competitor gets cited more often, and it answers from your project's data, then links to the page where you act. It never uses credits. See the AI assistant.
- MCP integration (Pro and Agency). Like Keyword.com, Mentionable ships an MCP server. It exposes prompts, competitors, sources, fan-outs, Reddit and backlink opportunities, so users can query their visibility data directly from Claude Desktop, Cursor, ChatGPT, or Claude Code.
- One-shot white-label GEO audit (Agency). Mentionable Agency includes a shareable client report under your brand: competitor ranking, personas, competitor matrix, prompt coverage, recommendations, content ideas, and top sources, with each section easy to hide.
Start tracking your AI visibility across 7 AI engines with Mentionable's 7-day free trial, no credit card required.
