About BitterDesk

BitterDesk is an AI-powered support chat platform designed for websites of all sizes. We believe every visitor deserves instant, accurate answers — without making businesses hire round-the-clock support teams or build complex chatbot flows.

        Our mission: Make customer support instant, accurate, and effortless for every website on the internet.
      

How BitterDesk Works

BitterDesk embeds as a single script tag on your website. Once installed, it automatically understands your site's content and can answer visitor questions in real time. There's no training data to prepare, no decision trees to build, and no ongoing maintenance required.

The AI reads your published content — product pages, documentation, FAQ sections, blog posts — and uses that knowledge to provide contextually relevant answers. When it can't answer confidently, it routes the conversation to your team with full context attached.

What Makes BitterDesk Different

Zero configuration: Add one script tag and the chat widget appears. The AI learns from your existing content automatically.
Context-aware routing: When the AI can't answer, conversations route to humans with the full chat history and visitor context.
Privacy-first: Visitor conversations are processed in real time and not stored beyond the active session unless you explicitly enable logging.
Platform-native: Built on the Radicchio hosting platform, BitterDesk integrates natively with form submissions, analytics, and deployment pipelines.
Lightweight embed: The chat widget adds less than 15KB to your page. It loads asynchronously and never blocks your site's rendering.

Built for the Portfolio

BitterDesk is part of the Bitter platform constellation — a suite of tools that power portfolio websites. Every site hosted on Radicchio can enable BitterDesk support with a single configuration flag. The integration handles widget embedding, conversation routing, and analytics collection automatically.

Sites like FreeKakuro, Ruedoku, EnvLint, and SiliconScore all use BitterDesk for customer support. The platform handles thousands of conversations across the portfolio without per-site configuration.

Technology

BitterDesk runs on a modern stack designed for reliability and speed:

Edge delivery: Chat widget assets served via Cloudflare's global CDN for sub-50ms load times worldwide.
AI processing: Natural language understanding powered by large language models, with response times under 2 seconds.
Webhook integration: Real-time conversation events delivered via webhooks for CRM integration, analytics, and custom workflows.
Form collection: Built-in contact form with spam filtering and structured data extraction.

Getting Started

To add BitterDesk to your website, embed the support widget script tag in your HTML. For Radicchio-hosted sites, enable the support_widget_enabled flag in your site configuration. The widget will automatically appear and begin answering visitor questions using your site's content.

For custom integrations, BitterDesk provides a REST API for managing conversations, retrieving chat history, and configuring AI behavior. See the main site for documentation and integration guides.
