Custom AI Telegram Bot
Built in 7 Days

Voice commands, text flows, automations, integrations — your custom Telegram bot, deployed and production-ready in a single sprint. You own the source code. Fixed price from €490.

What Type of Bot Can I Build?

Every bot is custom-built from scratch. These are the most common patterns:

Voice + AI Send a voice message → get a transcription, summary, or action back.
AI Assistant Chat-based assistant with memory, custom persona, or domain knowledge.
Data / Signals Scheduled alerts, market signals, monitoring — delivered to Telegram.
Language Tutor Conversational practice bot with pronunciation feedback (see Milica, Zosia).
Productivity Note-taking, shopping lists, task managers powered by AI (see GrassShopper, Zettelkasten).
Intake / Booking Chat-based intake forms, scheduling, CRM integration (see Reachable).

What's Included — Fixed Scope

Bot Architecture aiogram 3.x (async Python). Command handlers, conversation states, inline keyboards.
AI Integration OpenAI / Claude API wired to your core use case. Voice transcription via Whisper if needed.
Persistence Layer SQLite or PostgreSQL for user data, conversation history, or domain data.
Deployment Webhook-based deployment on Render or VPS. Stays online 24/7.
Admin Controls Basic admin commands (broadcast, user stats, on/off switches).
Post-launch Support 14 days of bug fixes and adjustments after delivery.

Frequently Asked Questions

Do you use BotFather templates or third-party bot platforms?

No. Every bot is written in Python using aiogram — the async Telegram Bot API framework. No ManyChat, no Botpress, no drag-and-drop builders. The code is yours and portable.

Does the bot support voice messages?

Yes. Voice support uses OpenAI Whisper for transcription. The bot receives a voice note, transcribes it, processes it through your chosen AI model, and responds with text (or synthesized speech, if needed). See Milica AI Tutor as a live example.

What AI models can the bot use?

OpenAI (GPT-4o-mini / GPT-4o) by default. Claude (Anthropic), Gemini, or open-source models via Ollama are all supported. The model is part of the spec discussion on Day 1.

Can the bot handle multiple languages?

Yes — the bot can detect the user's language from their Telegram settings or message content and respond accordingly. See Milica (Serbian) and Zosia (Polish) as examples of language-specific bots.

Who owns the bot and code after delivery?

You own everything — the bot (@username stays with you), the server, and the source code. It's transferred to your GitHub on day 7.

Why choose Valdas over an agency?

Four reasons: Speed — 7 days vs 3–6 months for an agency. Fixed price — one invoice, no hourly billing, no scope creep surprises. Direct builder access — daily Telegram check-ins with the person writing the code. AI-first approach — every bot is built using vibe coding with LLMs, which is why 7-day delivery is possible.
