An AI Telegram bot uses a large language model (GPT, Claude, or Gemini) to hold real conversations — not scripted flows. Done well, it answers product questions from your catalog, qualifies leads, provides 24/7 support, and even sends voice replies. Done poorly, it hallucinates and racks up API bills. We ship the former.

What we build

  • AI customer support bots — answer product / policy / order questions from your own knowledge base, escalate to humans when needed.
  • AI sales assistants — qualify leads, answer buyer questions, hand off warm leads to sales (see our AI Sales Bot case study).
  • Voice-enabled bots — on-demand voice replies via edge-tts or ElevenLabs, delivered as Telegram voice notes.
  • Multilingual bots — auto-detect user language, reply in it, no separate deployments.
  • Content generation bots — captions, images (via DALL·E or Imagen), summaries, translations.
  • Agentic bots — bots that call your APIs (order lookup, calendar, CRM) via function-calling.

How it works

  1. Discovery call (free). We learn what the bot needs to know and do.
  2. Fixed quote in 24 hours, including LLM choice recommendation.
  3. Build in 2–3 weeks — system prompt tuning, RAG index build, streaming responses, human handoff, admin controls.
  4. Launch & monitor. Analytics dashboard, weekly conversation review, prompt/index updates.

FAQ

Which LLM — GPT, Claude, or Gemini?

Gemini Flash for cost-efficient high volume, Claude Sonnet for tone-sensitive interactions, GPT-4o mini as a balanced default. We recommend based on your use case — see our AI chatbot guide for the trade-offs.

Monthly running cost?

For ~1,000 conversations/month: $0.30–$14 in LLM charges depending on model, plus $5–$15 hosting. Under $40 total for most cases.

Can it answer from my documents?

Yes — we build RAG over your content so answers are grounded in your business, not generic model knowledge.

Voice bots?

Yes — on-demand voice replies via edge-tts or ElevenLabs, sent as native Telegram voice notes.

Can the bot call my APIs?

Yes — via LLM function calling. Order lookup, calendar checks, CRM updates, any REST endpoint you expose.
