Lumen | AI Search Visibility Tracker

When someone asks an AI assistant “what is the best tool for X”, the answer names three or four brands and links a handful of sources. That answer is the new search result page, and most brands have no idea whether they appear in it.Lumen is a self hosted, white label platform that measures exactly that. It sends your buyers’ real questions to the major AI answer engines through their official APIs, samples each prompt repeatedly, and reports whether you were mentioned, whether you were cited, how much of the answer space you own against named competitors, and what to fix.It ships in two halves, and the price covers both: the Laravel platform your clients sign in to from a browser, and a Flutter app for iOS and Android that runs on the same install. Full source for each.Please read first: this is an AI powered product, and it depends on paid third party servicesLumen is an AI powered product. Its core function — measuring how a brand appears in AI generated answers — is carried out by large language models operated by other companies. Lumen contains no model of its own and produces no measurements on its own. Every live run, every score derived from one, and every recommendation it writes is generated by an external AI service that you connect using your own API key. AI generated output can vary between runs, can be incomplete, and can be wrong; Lumen reports the sample size behind every figure for exactly that reason, and results should be reviewed before being presented to a client as fact.Those services cost money, and that money is not included in the price of this item. This purchase buys the software and its source code. It does not include, resell, or cover usage of any third party service. To run live measurements you need your own paid account with one or more AI providers — OpenAI, Anthropic, Google, Perplexity, xAI or DeepSeek — and each of them bills you directly for what you use. To charge your own clients you need your own Stripe account, which charges its own fees. These accounts are yours, their pricing is set by them and can change at any time, and none of it is covered by the purchase price. A full breakdown is in Third party services and costs below.What makes this different from an SEO rank trackerRank trackers measure blue links. Lumen measures the answer itself. Three things follow from that, and they are the whole product:One question is a coin flip. AI answers change between identical questions, so a single screenshot proves nothing. Every prompt runs several times on every engine and every number is reported with the sample size behind it.Being named is not being cited. A brand can be described glowingly in an answer that links only to a competitor’s blog. Lumen parses the real linked sources behind each answer, so you can see the domains an engine actually trusts for your category.Findings become work. Gaps turn into an ordered list of actions, so the report ends with what to do rather than a wall of charts.Core featuresMulti engine visibility tracking. Six answer engines out of the box, each queried through its own official API. Web search grounding is supported where the provider offers it, so answers reflect live sources rather than training data.Share of voice. Your mention share measured against the competitors you name, per engine and over time.Citation and source analysis. The actual domains behind each answer, ranked by how often they are pulled in, with your own domain highlighted.Sampling with real statistics. Configurable runs per engine, mention rate, average position, and sentiment, all carrying their sample size.AEO readiness audit. Schema markup, answer structure, llms.txt and crawler access scored out of 100, with the failing checks explained.Prompt library. Branded, category, comparison and problem led prompt types, so you measure the questions buyers actually ask.White label client reports. Branded PDF and CSV exports carrying your name and colors, not ours.Multi tenant with teams and seats. Run many clients from one install, each with an isolated workspace, its own branding, and roles capped by plan.Credit metering and billing. One credit is one prompt sent to one engine, priced per engine. Stripe checkout, plans, credit packs and a full subscription lifecycle are included.
