Custom AI features, automations, and intelligent tools built into real products that ship — by an engineer who treats AI as a way to solve problems, not a buzzword to sell.
I’m Ken Key, a Long Island AI developer who builds artificial intelligence into products people actually use — not slide decks. The hype around AI is deafening right now, and most of it is noise. My job is to cut through it: figure out where AI genuinely makes your product faster, smarter, or cheaper to run, build that, and be honest with you about where it isn’t the answer yet.
In practice that means integrating large language models like OpenAI’s GPT and Anthropic’s Claude with proper prompts, guardrails, and cost control; building retrieval and search over your own data; adding assistants, summarization, and recommendations inside your app or website; and automating the repetitive work that quietly eats your team’s week. I already ship AI features in real software at KeyInventions — and because I build the apps and the backends too, the AI isn’t a disconnected experiment; it’s wired into something that works.
Chat, search, summarization, recommendations, and assistants built into your app or site — useful, not gimmicky.
OpenAI, Claude, and open models connected with solid prompts, guardrails, and cost control so it’s reliable and affordable.
Pipelines that handle the repetitive, copy-paste work your team shouldn’t be doing by hand.
I build what genuinely helps and tell you plainly where AI isn’t ready — no magic promises, no wasted budget.
We talk through what you’re actually trying to achieve. If I’m not the right fit, I’ll say so and point you somewhere better.
I design and build it properly, keep you in the loop, and make the trade-offs visible instead of hiding them.
You get something fast, documented, and maintainable — and I’m here when you need to grow it.
Concretely: answer customer questions, summarize long documents, draft and triage content, search your own data in plain English, recommend the right thing, and automate repetitive tasks. We start from a real problem you have, not from “let’s add AI.”
Whichever fits the job — OpenAI’s GPT, Anthropic’s Claude, or open-source models you can run yourself. The right choice depends on accuracy, privacy, and cost, and I’ll recommend honestly rather than defaulting to the trendiest one.
It’s handled deliberately. I’m careful about what gets sent to third-party models, when to keep data in-house, and how to keep you in control. Privacy and cost are design decisions, not afterthoughts.
Yes. A lot of AI work is integrating it into something that already exists — your site, app, or internal tools — rather than starting over.
