As answered by people managing DevFinanceTools and OnlyChatAI.
OnlyChatAI's answer:
It is built for one job: running fan conversations for OnlyFans and Telegram creators end to end, not a generic chatbot. It sells through scripted PPV funnels, supports Telegram Stars in-chat, remembers every fan, and follows up when a fan goes quiet. It is built and run daily by an agency on its own creators, 100% AI, no human chatters.
OnlyChatAI's answer:
Large language models with our own persona and sales layer on top, native integrations with OnlyFans and the Telegram Bot API (including Telegram Stars payments), and our own inference infrastructure. Web dashboard for operators.
OnlyChatAI's answer:
OnlyFans and Telegram creator agencies; we do not publish client names
OnlyChatAI's answer:
Because it is measured on sales, not on replies. Platform figures, September 2026: more than $2M in sales generated every month, 900+ active creators, a 43% unlock ratio on paid media sent by the AI, 17 months on the market. Every figure is defined on only-chat.ai/about. Pricing is simple: a flat monthly fee per creator plus a commission only on what the AI sells.
OnlyChatAI's answer:
OnlyFans and Telegram creator agencies, from a few creators to hundreds, and independent creators who want their inbox handled 24/7 without hiring chatters.
OnlyChatAI's answer:
We run a creator agency ourselves. Chatting was the job that ate every hour and every margin: hundreds of fans a day, each expecting an instant, personal answer, and revenue depending on how well the conversation sells. We built the engine we needed, ran it on our own creators first, then opened it to other agencies in May 2025.
