No-code AI chatbot trained on your own files, audio and video
Train on website URLs, PDFs, Word and Excel files, plus audio and video content — an unusually broad ingest list for a no-code builder.
Extract knowledge from recorded calls, lectures or videos so the bot can answer from spoken content, not just written documents.
Run the same bot on your website, in Slack, on WhatsApp and through native iOS and Android apps for support on the go.
Match the widget's look, tone and styling to your brand so it reads as part of your site rather than a generic tool.
Build a knowledge chatbot for your website in minutes, no code
Connect your own OpenAI key for GPT-3.5, GPT-4 or GPT-4o so you control AI usage costs — Ghostly only charges for the bot infrastructure.
Upload PDF, text and Markdown files and add website URLs; you can revisit and change the files your bot is trained on at any time.
Shape exactly how your bot responds with a configurable system prompt, predefined responses and welcome messages.
Adjust the colour theme, logo and primary colours, and choose dark or light mode so the chatbot fits your website.
