24/7 support & FAQ automation
Your customers get instant, accurate answers to repeat questions at any hour — so your team stops copy-pasting the same replies.
Custom chatbots for WhatsApp, Instagram, Telegram & websites
I build custom chatbots — rule-based, AI/LLM, or a hybrid of both — that handle support, questions and orders on the channels your customers already use: WhatsApp, Instagram, Telegram and your website. They reply instantly, hand off to a real person when it matters, connect to your CRM and documents, and you own the code. Live in about two weeks, supported after launch.

What I build
Chatbots that do real work for your business
Not a toy widget. A bot that answers customers, captures leads and takes orders on the channels they already use — and that you fully own.
Lead capture & qualification
Greet, qualify and route leads from DMs and comments automatically — before they lose interest and message a competitor.
Orders, bookings & menus
Take orders, bookings and enquiries right inside the chat — exactly like the live restaurant bot below.
AI conversations with a safety net
Natural AI answers (Claude, OpenAI) with a rule-based fallback and instant human handoff — so a customer is never left stuck.
One bot, every channel
WhatsApp, Instagram Direct, Telegram and your website from a single codebase. Add a channel without starting over.
Built to be supported
Health checks, monitoring and a maintenance relationship — the bot is looked after, not delivered and forgotten.
Every type of chatbot
Not just "an AI bot" — the right type for your job
Some jobs need fast, predictable rules; some need a language model; most work best as a mix. I build all of them and pick what fits your use case and budget.
Rule-based
Matches keywords and patterns to your pre-written answers. Fast, cheap and predictable — it only returns the answers you approved, ideal for clear FAQs.
Predictable$0 per message
AI / LLM-based
Uses a language model (Claude, GPT) to understand natural language and generate replies. Flexible and conversational, with usage billed per call.
ClaudeOpenAI
Retrieval (RAG)
Searches your knowledge base, then answers from what it finds — grounded in your real documents and far more reliable than free-form AI. (This site's own assistant works this way.)
GroundedYour docs
Flow / decision tree
A guided, step-by-step conversation — the user picks options and the bot follows a script. Great for wizards like order forms, bookings or risk calculators.
GuidedStep-by-step
Hybrid
Rules handle the common cases; AI handles the rest, with rules as a safety net. The best balance of speed, cost and reliability for most businesses.
Rules + AIBest value
Which do you need?
Not sure? Tell me what the bot should do and I'll recommend the right type — my live bots already cover rule-based, AI, RAG, flow and hybrid.

Why custom Python
Why not just use a no-code builder?
Builders like ManyChat or SendPulse are quick to start, but they charge more as you grow, box you into preset blocks and keep your data. A custom Python bot flips every one of those.
| What matters to you | No-code builder | Custom Python bot |
|---|---|---|
| Monthly cost | Subscription grows with your audience — often hundreds a month | Flat, low hosting — a few dollars a month on your own cloud, at any volume |
| Custom logic | Limited to preset building blocks | Anything you can describe can be built |
| Integrations | Need Zapier / Make add-ons — extra fees, more to break | Direct links to your CRM, database and payment tools |
| Peak load | Can lag or fall over during promos and spikes | Handles the spike and keeps replying instantly |
| Your data | Stored on the builder's servers | You own the code and the data — no lock-in |
| AI | Marked-up, limited AI add-ons | Full AI integration (Claude, OpenAI) on your terms |
Reliable by design
Instant replies, graceful human escalation, isolated error handling, automatic retries and a health-check endpoint. My bots have been verified running 72+ hours straight without a crash.
Pricing & transparency
Clear prices. Pay once. Own the code.
No hidden platform fees and no monthly subscription that grows with your success — you pay for development, and the bot is yours.

🎁 Limited launch offer: ask about my $0 hosting & AI setup — deployed on a free-tier cloud
with premium AI access included, so there are absolutely no monthly bills.
What you get
Pay once. Own it. Run it for very little.
Every bot ships on the same principle — no platform tax that grows with your success, and it's yours to keep.
You pay once
Pay for development, and the bot is yours — source code and all. No platform tax that grows with your success.
Low running cost, your cloud
Deployed to the platform you prefer — your AWS, Google Cloud, a small VPS or another host — where it runs for just a few dollars a month.
Scale in one click
It runs on a real cloud platform. When traffic grows, upgrade CPU/RAM from the console — no reinstalling the bot or its setup.
Supported after launch
Monitoring, maintenance and content updates so the bot keeps running and improving well past launch.
Ask about my zero-cost hosting offer — for the right project I can deploy to a free-tier cloud setup and include premium multi-model AI access. Tell me about your bot and I'll say if it qualifies.
How it works
From idea to a live, supported bot
A simple, predictable path — and it doesn't end at launch.
1 · Tell me what it should do
A quick call or email. What channel, what questions it should handle, and which systems it should connect to.
2 · I build and deploy it
I develop the bot in Python, connect your channel and any integrations, and deploy it to your own cloud account.
3 · You test it live
You message the bot yourself, we refine the answers and flows, and only go live when it feels right.
4 · I keep supporting it
Monitoring, maintenance and content updates. Unanswered questions get logged so the bot keeps getting smarter.
Focus area
A special interest in finance, trading & crypto
I develop applications in the finance area, and it's what I follow personally — markets, trading and cryptocurrency. If your bot lives in that world, you're talking to someone who actually understands it.
My live WhatsApp Trading FAQ bot is the proof: it teaches indicators, risk management and market psychology in plain language.
These bots educate — they explain concepts and help with risk. They do not give buy or
sell recommendations or financial advice.
# A real exchange with the live bot
User: RSI
Bot: RSI measures momentum on a 0–100 scale.
Below 30 can mean oversold; above 70,
overbought.
User: position size
Bot: Send your balance, entry and stop-loss.
I'll size the trade to your risk rule.
User: mentor
Bot: Forwarded to a human mentor. Automatic
replies are paused until they finish.
FAQ
Frequently asked questions
The questions business owners ask before starting a chatbot, answered directly.
What does Alex Koziy build?
Custom chatbots in Python for business. They run on WhatsApp, Instagram Direct, Telegram and websites, and handle customer support, FAQs, lead capture, orders and bookings. They can use AI (Claude, OpenAI) for natural conversation, with a rule-based fallback and instant handoff to a human when needed.
Which channels do the chatbots work on?
WhatsApp via the official WhatsApp Business API (Meta Cloud API, Twilio or 360dialog), Instagram Direct, Telegram, and your own website. One codebase can serve several channels, so you are not locked into a single platform.
Why custom Python instead of a no-code builder like ManyChat?
No-code builders charge a monthly subscription that grows with your audience, limit you to preset blocks, and keep your data on their servers. A custom Python bot runs on your own server for a few dollars a month regardless of traffic, supports any logic you can describe, integrates directly with your CRM, database and payment tools, and — most importantly — you own the source code and the data.
Can the chatbot use AI like ChatGPT or Claude?
Yes. The bots integrate directly with AI models such as Anthropic's Claude and OpenAI for natural, context-aware conversation. AI answers are backed by a rule-based fallback, so if the AI is unavailable the bot keeps working instead of going silent.
Do I own the chatbot and its data?
Yes. You receive the full source code and the bot runs on your own cloud account, so the customer data stays with you. There is no platform lock-in and nothing to lose if a third-party builder changes its pricing or policy.
How much does it cost to run?
Running costs stay low. The bot is deployed to the cloud platform you prefer — your own AWS, Google Cloud, a small VPS, or another host — and because it's a lightweight service it runs on modest resources, typically only a few dollars a month regardless of how many customers message you. You pay once for development, you own the code, and any AI usage you enable is billed to you at cost, with no platform markup.
Can the chatbot connect to my CRM, database or payment system?
Yes. Because it is real Python code, the bot talks directly to REST APIs, databases (PostgreSQL, MySQL, MongoDB) and business systems — no fragile Zapier or Make middle-layer and no extra subscriptions.
What happens after the bot is launched?
The bots ship with health checks, structured logging and monitoring, and I offer ongoing support and maintenance. Every unanswered question is logged so the bot's knowledge keeps improving over time. It is a maintained product, not a hand-off-and-vanish delivery.
Can you build a chatbot for trading or finance?
Yes. I develop applications in the finance area and follow trading and cryptocurrency closely. A live example is my WhatsApp Trading FAQ bot, which teaches trading concepts, indicators and risk management. Note: these bots educate — they do not give buy or sell advice.
Do you also do other kinds of software?
My focus is Python chatbots. If you're curious about the background behind that, I have 20+ years in enterprise software — see my enterprise background and ZK & Keikai work.
