Build pro directories without writing a listing

9 AI models working together: one researches real business data, another writes it up, another prepares the markup Google needs. If one fails, another takes over. It seeds a directory from scratch (open sources or your list) or fills in the listings you already have. Got a powerful GPU? You can generate listings for free with your own computer, no cloud AI charges.

What Cantera does

🔄

9 AIs as a team. If one fails, another keeps going

If one AI is overloaded, it jumps to the next. Your work never stops at 3 pm just because OpenAI has an outage.

🔍

Real data, not invented

Before writing each listing it checks the business's official website, social profiles, and Google Maps. What it says is true — not made up by AI.

⚡

Google sees them as real businesses

Adds the invisible markup Google needs ("this is a plumber in Madrid, phone X, hours Y"). Your listings appear with stars and maps in search results.

🏠

Free generation with your own GPU

Got an RTX 4060/5060/4090 or similar? You can generate listings without paying anything for cloud AI. Your computer does the work. Private, unlimited, and no external API costs.

∞

Create unlimited directories

As many directories as you want, as many listings as you need. No cap on sites or categories. The only limit is the plan you pick.

🚀

Bing and Yahoo find out instantly

The moment you publish a new listing, search engines get the ping in real time. No waiting days for them to discover it on their own.

🎯

A quality gatekeeper at the door

Every listing gets a 0-10 score before it goes out. Below 6 it is not published; between 6 and 7 it waits in review for you to check. Nothing weak goes out under your name.

🔁

Improves what you already published, on its own

Connect your Google Search Console and Cantera spots the listings that almost rank, audits them and rewrites them with the keywords that actually bring you visits. No URL changes, no losing what already works.

🔐

Your keys, on your PC, encrypted

You use your own free accounts for each AI and your WordPress. Everything is stored encrypted on your computer, never on our servers. If you stop using Cantera tomorrow, nothing of yours is left outside your PC.

CAPTURAS REALES

Real views from the app

Screenshots of the Cantera panel in action. Real site and business names swapped for demo placeholders; everything else is exactly what you'll see.

Your own GPU generating listings. You see your installed Ollama models, which one is loaded, how many listings each has produced, its average score and speed. Plus a HuggingFace radar with new models that fit your hardware. No cloud AI bills.

Live GPU health: temperature, usage, VRAM, power draw, fan, and tokens per second. Below it, the quality histogram of your listings. If something goes off, you see it instantly.

How much your listings cost, no surprises: with each AI free tier plus your own PC, 0 out of pocket. The per-provider breakdown watches that no free quota runs dry and tells you where you still have credit left.

HOW IT WORKS

How it works, step by step

⏱️ ~15 minutes for simple setups. More if your stack is complex or plugin-heavy. Then a few details to tweak. We'll publish step-by-step videos on YouTube and link them here.

  1. 1

    Connect your WordPress

    One click with OAuth. SeoNova detects your hosting, installed plugins, and current setup. No code or FTP needed.

  2. 2

    Pick which tool to use

    For Tesora: nothing to connect — you get the daily domain report and you decide. For Cantera: you say category + location (e.g. "plumbers Madrid"). For WPO Toolkit: connect your Cloudflare in one more click and we turn on the 3 layers (speed, performance, security).

  3. 3

    The tools work on their own

    Cantera researches real businesses (website, social, Maps) and publishes SEO listings with schema. WPO Toolkit tunes speed, screens every visit, and filters bots, scrapers, and the people inflating your AdSense. 24/7, hands-off.

  4. 4

    See results in real time

    One panel: published and indexed listings, your site's real speed, % of users with AdBlock, hourly RPM, blocked visits, and alerts if anything breaks. Via email or Telegram.

FAQ

Frequently asked questions

How much does it cost to build a directory with SeoNova? +
Final pricing will be announced at the 2026 launch. The first 500 waitlist subscribers get 50% off for the first 3 months. We expect ranges between $39-$99/month depending on listing volume.
Do I have to pay for AI every month? +
Not if you have a powerful GPU. SeoNova can also generate listings using your own computer (with cards like RTX 4060/5060/4090 or similar) and a free program called Ollama. It's private, unlimited, and no cloud AI bills. If you don't have a GPU, you use our cloud AIs and pay per use.
Do I need WordPress installed? +
Yes. Cantera works as a WordPress + Directorist plugin integration at launch. If you don't have WordPress, we'll help you set it up (~15 min for simple cases). Coming soon: WooCommerce, Webflow, and other platforms.
How many listings can I generate? +
No technical limit — depends on plan. Basic plan allows 50 listings/month, higher plans up to 50,000+/month. Custom plans for massive niches.
Will Google treat the listings as auto-generated content? +
No, because SeoNova researches real data for each business (official website, social, maps) and combines it with AI writing that passes content detectors. Google treats these listings as legitimate content.
What about future platforms? +
Directorist users get priority access to migrate to new platforms (WooCommerce, Webflow, etc.) when available, at no additional cost.
Is there support in English? +
Yes, direct support in English and Spanish. And if you need another interface language, we add it on request.

What's new in Cantera

The same list you see inside the app, version by version.

  1. v1.1.2

    Latest version

    Fixed

    • **If your computer went to sleep, Cantera lost the listings it had half-done and then ran slower.** Not any more: it starts clean, picks them back up and keeps its pace.
    • **Plenty of listings with good data were being set aside by mistake.** Over a thousand that were waiting for no reason have been brought back.
    • **All your sites now take turns.** The ones at the end of the list barely produced anything before.
    • **Cantera can read PDFs again.** Data that only lives there is no longer lost.
    • **If your hosting hiccups, the listing no longer takes the blame.** It used to be marked faulty and set aside for a month.
    • **A listing that couldn't be published in full no longer counts as published.** The whole thing is retried instead of sitting half-done on your site.
    • **Links inside the listing text are back**, not just in the box at the bottom.
    • **Listings due for a second round of research now get it.** Their turn never came before.
    • **Cantera no longer keeps knocking when a server has said no.** It waits before asking again.
    • **Game mode switches itself off after 6 hours**, even if you never restart Cantera.
    • **With Game mode on, Cantera no longer restarts itself** just because no new listings came out.
    • **The panel can no longer show one mode and run another.**

    Better

    • **Opening Cantera starts everything it needs, with no windows.** And it never starts on its own with Windows: turn the PC on for something else and your graphics card stays free.
    • **In the evening, when the free cloud runs out, Cantera no longer trips over itself.** It only opens as much as your card can handle at once.
    • In the published chart, each bar now names the model next to the provider.
