Citon AI is a done-for-you AI citation service for companies that build developer tools, APIs, CLIs, MCP servers and AI infrastructure. The engagement starts with a free Gap Report that measures twelve buyer queries, five repeats each, against live answers from ChatGPT, Claude and Perplexity, names the failure mode, and ranks every host the models cite. Retainers then do the work those models reward: answer pages on the client's site, off-site placements, Reddit, Hacker News and Quora mentions, review-site and developer-surface coverage, plus an agent-readiness pass and MCP work. Clients get three alerts a week rather than a dashboard, a scoped API and an MCP server, and at day 90 a causal-lift report in which half the queries were worked and half were left as a control. Services: answer engine optimization for developer tools, and Reddit and community marketing for dev tools. Retainers start at $6,000 per month on a 90-day minimum; a $3,500 Citation Diagnostic is credited to month one.
