Botpress vs SESTEK

Botpress is a platform for building AI agents and chatbots powered by large language models. The Canadian company began with an open-source chatbot framework and later rebuilt the product as a cloud platform centered on a visual studio, where builders combine autonomous LLM nodes with structured workflows and can drop into JavaScript code whenever a step needs custom logic.

Agents draw on knowledge bases built from websites, documents and tables, call external systems through more than 100 integrations, and deploy to web chat, WhatsApp, Messenger, Telegram, Slack, Microsoft Teams and other channels. Human handoff, analytics, versioning and role-based collaboration are layered across plans. Pricing starts with a free plan of 100 conversations, then Plus and Team plans priced by included monthly conversations, with extra conversation packs and an AI usage allowance; usage beyond that allowance is billed, so the total cost depends on traffic and the models you choose.

Botpress fits developers, agencies and product teams building several agents that must follow defined processes and connect to real systems. Non-technical users who simply want a website bot trained on their content will be faster with Chatbase, Voiceflow offers a more design-oriented collaboration experience for conversation teams, and support organizations already on a help desk may prefer Intercom Fin or Zendesk AI agents. The product evolves quickly, so older tutorials and community answers can go out of date.

SESTEK is a conversational AI and speech technology company founded in Istanbul in 2000 by Levent Arslan, a former Boğaziçi University professor. Since October 2022 it has been part of Unifonic, the Saudi customer engagement platform. SESTEK builds AI for contact centers: virtual agents that answer calls and chats, in-house speech recognition and text to speech, and analytics that transcribe and score every customer conversation. Much of the suite has been sold under the Knovvu brand.

The product line covers AI agents (the Knovvu Virtual Agent gained LLM-based agentic capabilities in April 2025), Agent Assist and Agent Copilot for live guidance to human agents, a Virtual Translator, conversational analytics, automated quality management (AQM) and coaching. The same codebase runs in the public cloud, hybrid or fully on-premise. There are no public plans: every deal is an enterprise project with a custom quote.

SESTEK fits large contact centers in banking, telecom and energy, especially where Turkish or Arabic speech accuracy and on-prem hosting matter. It is not a self-serve chatbot for small sites. Yellow.ai is broader on omnichannel chat, Ada is a cloud-only service automation product for digital brands, and CBOT is the closest local rival in Turkish banking; SESTEK is stronger on voice and speech analytics than all three.

Recent proof point: Arçelik put Knovvu Agentic AI live in its Turkish call center in January 2026, and SESTEK's case study reports 70% of cases resolved without a human agent. Buying tip: run a pilot on your own recorded calls first.
