CORTEX — Digital Studio
Tell us what's costing you most — missed calls, a website that doesn't sell, paperwork that eats your nights — and we'll build the fix. Scroll to see the kinds of problems we've solved.

Websites
A site that doesn't bring in work is an expensive brochure. We rebuild it into a conversion-first storefront that turns visitors into booked jobs — like The Azure Group, with live valuation and neighborhood pages.
Phone Bots
Every call that rings out after 5pm is a job your competitor got. We build voice agents that answer, book, and qualify — around the clock.
Telegram Bots
The paperwork after every job is the part that eats your nights. Text the Invoice Bot and it drafts the invoice for Pedro's job, emails him, and logs it to QuickBooks — in seconds.
What we build
Award-grade sites that move, breathe, and convert.
Voice agents that answer every call like your best rep.
Bots that sell, support, and ship updates where users live.
WhatsApp agents, AI concierges, and whatever the web does next.

Three demos — one a real client site, two simulations. No sign-up, no video. Poke at them yourself.
Mission control
Calls answered, invoices sent, orders shipped — a simulated look at the systems we build, working while you do literally anything else. The figures below are illustrative, not client data.

The studio
CORTEX is a two-person studio that ships like a team of ten. We design, engineer, and obsess over every pixel and every millisecond — no handoffs, no telephone game. If it carries our name, it feels alive.

Straight answers
The things people want settled before they pick up the phone — money, ownership, and what happens if it goes wrong. Answered here so you don't have to ask.
Every build has a one-time setup fee and a monthly. How you cover them is your call: monthly with $0 down, setup plus monthly, or pay in full and own it outright with no monthly at all. The estimator above prices all three as you click — no email wall, no “contact us for pricing”.
What it gives you is a ballpark in US dollars, not an offer. The exact figure comes in writing after a 15-minute call, once we know what we're actually building.
Third-party running costs. Your domain, hosting, a phone number for a voice bot, AI usage — those are billed by the companies providing them, and the estimate doesn't model them or taxes.
They're usually small next to the build, but you shouldn't find out about them afterwards, so the ones that apply to you go in your written quote.
It depends on scope, and anyone who gives you a date before they know the scope is guessing. A landing page and a web app are not the same job.
If you need it sooner, the estimator has a rush option — it lifts the setup fee, never the monthly. A real date comes with the real quote, before anything starts.
Pay in full and you own it outright, no monthly. The monthly plans spread that build cost over time instead, so what transfers and when is written down rather than left to assume.
Either way, ownership of the build — and who holds the domain, the accounts and the data — is settled in writing before work starts, not argued about later. Nothing you depend on gets held hostage.
On the monthly plan there's nothing holding you: $0 down, cancel anytime. On the others, what happens if either side walks away is in the agreement you sign — read that part properly, with your own lawyer if you want.
What we won't do is promise you a number. Nobody honest can guarantee rankings, leads or revenue, and “guaranteed #1 on Google” is how people get burned the first time. We'll tell you what we expect a build to change, and set it up so you can see whether it did.
No. You need to know your business — where the money leaks, which calls go unanswered, what customers keep asking for. That's the part we can't do without you.
We handle the rest end to end, and anything you'll want to change yourself later gets handed over in a form you can use without calling us first.
A couple of short conversations, and whatever already exists — logo, photos, price list, access to your domain. If it currently lives in a filing cabinet or in your head, that's fine too.
If the copy, the branding or the photos don't exist yet, that's a line item and not a blocker: copywriting, logo and branding, and moving your old content across are all options in the estimator.
Because there's nobody to hand you off to. You talk to Yisroel and Berel — the two people writing the code — during the project and after it. No account manager relaying your problem to someone you never meet.
And you don't have to take our word for it. The demos on this site are live, and the work above includes a real client store you can open and click through before you ever contact us.
