Gene KarasevAI features for web apps Available for work

Independent AI engineering studio

The AI layer for your web app — custom-built, not bolted on.

I build AI features into products — chat assistants, real-time lead capture, and grounded search that live inside your own app, branded to match, with your data staying yours. Every demo below is a working build you can click.

01 — Conversational lead qualifiers

Replace the form with a conversation that qualifies itself.

Both demos run on the same custom-built engine: a chat that captures each visitor in real time, scores them with transparent reasoning, and automatically creates a live-updating Google Sheet for every lead. The only thing that changes between them is one configuration file — same engine, different industry.

02 — AI knowledge & search

Answers built only from your own content.

Let visitors ask questions in plain language and get answers drawn only from your site's pages — with links to the exact sources, and nothing made up.

03Docs & site search

Lumen — ask the docs

A visitor asks in plain English and gets a straight answer built from your site's own pages — with citations, streamed live. No digging through menus.

Why custom

Engineered, not glued on.

Built in, not bolted on

Branded into your own app — not a generic third-party chat bubble.

Your data stays yours

No vendor servers, no per-message fees, no lock-in.

Secure by default

API keys live server-side and never reach the browser.

Grows with you

Configurable and wired into how your business actually works.

Need the AI layer for your product?

If you've outgrown an off-the-shelf widget — you want it branded into your product, your data kept private, and integrated with how your app actually works — that's exactly what I build.
