Overview

Chunky is an AI chatbot builder for customer support automation, explicit about its underlying stack: it “uses the ChatGPT API and Embeddings provided by OpenAI” to train a “super-smart chatbot” on a business’s own data, answering FAQs with contextual understanding rather than scripted, generic responses. No coding is required to set one up.

Training flexibility stands out – upload PDFs, point it at a website URL for automatic data extraction, or link a Google Sheet, then add the trained bot to any site with a single line of code or share a public testing link before going live. Multilingual support across roughly 95 languages, for both training data and responses, extends its reach well beyond English-only support tools.

Chunky targets businesses without dedicated technical teams that want to automate repetitive FAQ-style support and “save hours every week.” A Free Forever plan requires no credit card to start, with paid tiers available for higher usage on a separate pricing page.

Key features

  • Built on the ChatGPT API and OpenAI Embeddings for contextual, natural responses

  • One-line-of-code website embed, or a shareable public testing link
