Your buyers are asking AI, not Google. Lumen tells you what it says back.

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 services

Lumen 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.

You can evaluate the entire product before paying anyone: Lumen ships with a demo mode that runs the whole pipeline with no API keys, no network calls and no spend.

Live demo

Workspace demo: https://lumen.foundrcode.com/app
Email: owner@northgate.test
Password: password
Admin panel: https://lumen.foundrcode.com/admin
Email: demo-admin@example.com
Password: LumenAdmin!

Try the app on your own phone: an Android build is on the homepage at https://lumen.foundrcode.com — scroll to “The whole workspace, in your pocket” and tap Download for Android. Install it and sign in with the workspace demo account above. It is pointed at the demo, so you see the same live measurements the browser shows. Android warns before installing anything from outside the Play Store; that is expected for a direct download.

The app is included as a Flutter project rather than a store listing, because it is your app: you point it at your own install, brand it, and publish it under your own developer accounts. Build it in three commands, or ignore it entirely — the platform is complete on its own, and its workspace already works in a phone browser.

What makes this different from an SEO rank tracker

Rank 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 features

Multi 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.
Alerts and scheduling. Daily or weekly runs on a single cron entry, with email and webhook alerts when a metric moves.
Admin panel. Plans, credit packs, engines, API keys, email templates and tenants, all editable without touching code.
White label control panel. Platform name, tagline, logo, favicon and accent color, all applied instantly from the admin panel with no file editing and no redeploy.
Your own legal pages. A rich text editor for your Terms and Privacy Policy, published at /terms and /privacy, or linked to policies you already host elsewhere.
Complete account flows. Self serve signup, sign in, and password reset with rate limiting, all sent through your own editable email templates.
Web installer. Requirements check, MySQL or SQLite, migrations, admin creation and activation from the browser, then it locks itself.
Native mobile app, source included. A Flutter client for iOS and Android covering every workspace screen: the dashboard, share of voice, prompts, runs and the full engine answers behind them, cited sources, AEO audits, actions, alerts, reports, team and billing.

The mobile app

The app is a client of your install, not a separate product with its own account system. Your clients sign in with the credentials they already have, see the same numbers computed by the same code, and cannot drift out of step with the browser.

One line to rebrand it. Only the address of your install is compiled in. The app’s name, tagline, accent color, logo, whether signup is offered and which features appear are all read from your server when it launches, so white labelling the app takes no second build.
Everything the workspace does. Run a measurement and watch the batch progress, read the full answer an engine gave with the brands and sources marked inside it, work the action list, add prompts and competitors, invite teammates, top up credits.
Built to feel like one product. The same palette, the same Nunito and Phosphor faces, the same Visibility Scope drawn the same way as the browser draws it.
Yours to publish. Full Flutter source, no obfuscation, no third party app framework subscription, and no runtime that phones home to us.

Publishing to the App Store or Google Play is optional and entirely yours: both charge their own developer fees, and both review submissions on their own terms. You can also distribute internally, or skip the app and use the browser workspace.

Two ways to sell it

Lumen ships with both business models built in, switched by a single setting:

You hold the keys. You add provider API keys once in the admin panel, stored encrypted. Your clients never see a key. They buy credits from you, and those credits meter the runs your keys pay for. This is how you make margin as an agency or reseller.
Clients bring their own keys. Each tenant supplies and pays for their own provider account. You charge for the platform instead of the usage.

White label settings: platform name, logo, favicon and accent color

Built for ordinary hosting

The core runs on plain shared hosting. Queue and cache are database backed, so Redis and a realtime server are optional performance upgrades rather than requirements. Background work needs one cron entry. Nothing loads from a CDN at runtime: fonts and icons are bundled locally.

PHP 8.2 or newer
MySQL 8 or MariaDB, or SQLite for evaluation
Apache, Nginx or LiteSpeed
Composer and Node.js once, to install dependencies and build assets

The app is built on your own machine, not on the server:

Flutter 3.9 or newer
Xcode for an iOS build, Android Studio for an Android build
Apple and Google developer accounts only if you intend to publish to their stores

Try it without spending anything

A demo mode runs the entire pipeline with no API keys, no network calls and no spend, using a bundled sample dataset. Install it, click through the whole product, and only add real keys when you are ready.

Activation

Enter your Envato purchase code during installation, or later under Admin → License. A new install runs for a week before activation is required, so you can look around first, and a development or staging domain never needs a code at all.

Documentation

The package includes a full installation guide written for non technical buyers, a configuration reference, a user guide, and a chapter on the mobile app — screenshots of what your clients see, how to point it at your install, how to rebrand it without a second build, and what publishing to the stores involves. Every install step states the expected outcome so you know what success looks like, mandatory setup is kept clearly separate from optional integrations, and each third party service is listed with what it does and what you can swap it for.

Third party services and costs (none of which are included in the purchase price)

Lumen is the software only. Every external service it can connect to requires its own account, is billed by that provider directly to you, and is charged at rates that provider sets and can change. None of these fees are included in the price of this item, and this purchase does not include credit, trial access, or a discount with any of them. The AI providers are required for live measurement — that is the product’s core function and it is performed by their models, not by Lumen. Everything else in this list is optional.

AI providers (OpenAI, Anthropic, Google, Perplexity, xAI, DeepSeek): pay per use, billed by the provider whose key is used. Required only for live measurements. Demo mode needs none of them.
Stripe: optional, and only if you charge your own clients. Standard Stripe fees apply. Leave it unconfigured and billing is simply hidden.
Email delivery: optional. Any SMTP account works, including your host’s. An HTTP mail API can be used instead.
Live chat: optional. Leave the key blank and the widget does not render.
Apple and Google developer accounts: optional, and only if you publish the mobile app to their stores. Both charge their own fees and review on their own terms. Building the app for your own devices or internal distribution does not require them.

Licensing

The Regular License covers a single operator running the platform for their own brands and clients, where end users are not charged for access. If you intend to run Lumen as a paid multi tenant service where other people pay to use it, the Extended License is the correct one.

Bug reports and installation questions are answered through the item support tab. Updates are free for the lifetime of the item.
