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.
Windows installer. Free during the beta.
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.
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.
Nombres de sitios y empresas reales sustituidos por demo.
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.

What's new in Cantera
The same list you see inside the app, version by version.
v1.1.1
Latest versionFixed
- **Some listings showed a phone number and address that did not exist.** When a website refused to hand over its data, Cantera kept a fragment of the page's code and took it for a real number. Not any more: if what arrives has no phone or address shape, it is discarded.
- Listings already published with that fault have been rebuilt one by one, with their real data or with none.
- **Cantera searches better.** The search engine it used had stopped responding and more than half the searches came back empty. Swapped for another one: now they come back full.
- When Cantera finds a business's official record in a public registry, it now always uses it. Before there were cases where it had it right there and did not look.
- If your internet drops, Cantera stops and waits instead of carrying on blindly.
New
- **Cantera now knows which town to search in.** Many listings only gave the state or region, and searching "in Colorado" or "in Catalonia" is almost like searching nowhere. Cantera now checks an open worldwide business map and, when it recognises the place beyond doubt, narrows the search to the exact town.
- Pages hiding behind a "log in" notice can now be read. Cantera used to give up before even trying.
- **And what it costs to read is no longer thrown away.** A social-network listing with the name, town, opening hours and reviews was discarded whole just for having no phone number. It now gets used.
