|
| Integrations & Channels |
-
Comes with its own chat/search interface rather than a “deploy everywhere” model.
-
No built-in Slack bot, Zapier connector, or public API for external embeds.
-
Most users interact through Pyx’s web or desktop UI; synergy with other chat platforms is minimal for now.
-
Any deeper integration (say, Slack commands) would require custom dev work or future product updates.
|
- Drop a chat widget on your site or hook straight into Slack, Telegram, WhatsApp, Facebook Messenger, and Microsoft Teams.
- Webhooks and Zapier let you kick off external actions—think tickets, CRM updates, and more.
- Built with customer-support workflows in mind, complete with real-time chat and easy escalation.
|
- Embeds easily—a lightweight script or iframe drops the chat widget into any website or mobile app.
- Offers ready-made hooks for Slack, Microsoft Teams, WhatsApp, Telegram, and Facebook Messenger.

|
| Core Chatbot Features |
-
Delivers conversational search over enterprise documents and keeps track of context for follow-up questions.
Appvizer reference
-
Geared toward internal knowledge management—features like lead capture or human handoff aren’t part of the roadmap.
-
Likely supports multiple languages to some extent, though it’s not a headline feature the way it is for CustomGPT.
-
Stores chat history inside the interface, but offers fewer business-oriented analytics than products with customer-facing use cases.
|
- Uses retrieval-augmented generation to give accurate, context-aware answers pulled only from your data—so fewer hallucinations.
- Handles multi-turn chats, keeps full session history, and supports 95+ languages out of the box.
- Captures leads automatically and lets users escalate to a human whenever needed.
|
- Powers retrieval-augmented Q&A with GPT-4 and GPT-3.5 Turbo, keeping answers anchored to your own content.
- Reduces hallucinations by grounding replies in your data and adding source citations for transparency.
Benchmark Details
- Handles multi-turn, context-aware chats with persistent history and solid conversation management.
- Speaks 90+ languages, making global rollouts straightforward.
- Includes extras like lead capture (email collection) and smooth handoff to a human when needed.
|
| Customization & Branding |
-
Designed as an internal tool with its own UI, so only minimal branding tweaks (logo/colors) are available.
-
No white-label or domain-embed options—Pyx lives as a standalone interface rather than a widget on your site.
-
The look and feel stay “Pyx AI” by design; public-facing brand alignment isn’t the goal here.
-
Emphasis is on security and user management over front-end theming.
|
- Tweak the widget’s look—logos, colors, welcome text, icons—to match your brand perfectly.
- White-label option wipes Ragie branding entirely.
- Domain allowlisting locks the bot to approved sites for extra security.
|
- Fully white-labels the widget—colors, logos, icons, CSS, everything can match your brand.
White-label Options
- Provides a no-code dashboard to set welcome messages, bot names, and visual themes.
- Lets you shape the AI’s persona and tone using pre-prompts and system instructions.
- Uses domain allowlisting to ensure the chatbot appears only on approved sites.
|
| LLM Model Options |
-
Doesn’t expose model choice—Pyx likely runs GPT-3.5 or GPT-4 under the hood, but you can’t switch or fine-tune it.
-
No toggles for speed vs. accuracy; every query uses the same model configuration.
-
Focuses on its RAG engine with a single, undisclosed LLM—less flexible than tools that let you pick GPT-3.5 or GPT-4 explicitly.
-
No advanced re-ranking or multi-model routing options are mentioned.
|
- Runs on OpenAI models—mainly GPT-3.5 and GPT-4—for answer generation.
- Flip a switch between “fast” (GPT-4o-mini) and “accurate” (GPT-4o) depending on whether speed or depth matters most.
