## Chat Data

Chat Data is a no-code-to-developer-friendly platform for turning enterprise knowledge into AI agents and customer-support chatbots. You connect your own content — documents, help centers, product catalogs, even video and audio — or point the agent at a custom model endpoint, then publish it wherever your customers already are: website widget, WhatsApp, Messenger, Instagram, Telegram, Line, Discord, Slack and a long list of connected platforms including Shopify, WooCommerce, Zendesk and WordPress.

What separates it from a plain FAQ bot is the depth of the agent runtime. Workflows can be described in natural language and triggered as AI actions, interactive responses can include charts, cards and carousels, and pre-integrated MCP connections expose more than 10,000 tools across 834 apps like Gmail, Google Calendar, Notion, Slack and GitHub. Voice is first-class too: agents answer real phone calls with natural speech, and you can supply your own ElevenLabs voice. When the AI reaches its limit, conversations escalate to human live chat on both your site and third-party channels.

For regulated industries the platform advertises HIPAA-aligned capabilities, automatic PII anonymization before prompts are sent to the LLM, medical and veterinary chat models, and a BAA available on the Standard plan and above. Teams get SSO white-labeling, an SDK that ties responses to logged-in user profiles, and a documented API for deeper integration. It is used by 1,000+ businesses, with a free tier to start and usage-based paid plans.

**Pricing & Plans:** Freemium with paid tiers. A free plan covers building and testing, while Standard and higher plans add higher usage limits and compliance features such as a BAA. Check the pricing page for current rates.

- **Model your own data:** Train agents on documents, help articles, video and audio, or connect a custom model endpoint so answers stay grounded in your business knowledge.
- **Omnichannel deployment:** Ship the same agent to your website, WhatsApp, Messenger, Instagram, Telegram, Line, Discord and Slack, plus e-commerce platforms like Shopify and WooCommerce.
- **Workflow automation and MCP:** Build automations with natural-language prompts, trigger them as AI actions, and reach 10,000+ tools through 834 pre-integrated MCP apps.
- **Real-time voice and live chat handoff:** Answer phone or in-app calls with a natural voice (including your own ElevenLabs voice) and escalate to human agents when the conversation needs it.
- **Compliance and privacy controls:** PII detection and anonymization before prompts reach the model, HIPAA-aligned tooling, SSO white-labeling, and SDK support for logged-in user experiences.

**Strengths:** Answers stay grounded in your own documents, catalogs and knowledge base, or in a custom model endpoint; Very broad deployment reach: website, WhatsApp, Messenger, Instagram, Telegram, Line, Discord, Slack and e-commerce platforms; Live human handoff, real-time voice and interactive UI responses in one platform; Strong compliance posture for healthcare and regulated use cases, including PII anonymization and BAAs

**Limitations:** Feature breadth means a learning curve for teams that just want a simple FAQ bot; Compliance features such as a BAA require paid plans (Standard and above); Best results depend on good upfront preparation of your knowledge sources

## Sierra

Sierra is a conversational AI platform aimed at businesses that want to improve customer experience and grow customer lifetime value. Instead of static chatbots, Sierra focuses on AI agents that can hold natural conversations, take actions through connected systems, and adapt over time. The company describes its offering as the leading conversational AI platform for businesses, used by large brand-name enterprises across sectors such as financial services, healthcare, telecom, media, travel and hospitality, retail, technology, and the public sector.

A central feature is Ghostwriter, an agent-building agent that can take unstructured input — standard operating procedures, transcripts, whiteboard photos, or audio recordings — or a plain-English goal, and turn it into a production-ready, multilingual, multichannel agent with built-in guardrails. Around it sits a set of operating tools: Insights Explorer for deep, research-style analysis of agent performance, Monitors that flag conversations needing attention, Experiments for multivariate testing of conversation design, and Observability that exposes tool calls, knowledge lookups, and latency. Horizon adds long-horizon planning, customer context memory, outcome optimization, and proactive engagement triggered by real-world signals.

Sierra deploys a single agent across chat, SMS, WhatsApp, email, voice, and ChatGPT, so customers get consistent help on the channel they prefer. Trust, security, and compliance are emphasized, including a public Trust Center. Notably, Sierra prices on outcomes rather than seats: the company states customers pay for a job well done, aligning cost with the value the agent delivers.

**Pricing & Plans:** Outcome-based pricing: Sierra states that customers pay for results delivered rather than per seat. Specific rates are not published and require contacting Sierra.

- **Ghostwriter agent builder:** Turn SOPs, transcripts, whiteboard photos, audio recordings, or a plain-English goal into a production-ready, multilingual, multichannel agent with built-in guardrails.
- **Omnichannel deployment:** Run a single agent across chat, SMS, WhatsApp, email, voice, and ChatGPT so customers get consistent help on their preferred channel.
- **Analytics and observability:** Insights Explorer, Monitors, Experiments, and Observability surface agent performance, flagged conversations, and every tool call, lookup, and latency event.
- **Horizon long-horizon planning:** Breaks complex outcomes into steps that improve over days or months, with customer context memory and proactive engagement triggered by real-world signals.
- **Outcome-based pricing:** Pay only for the value Sierra delivers, aligning cost with completed customer outcomes instead of seats or licenses.

**Strengths:** Ghostwriter builds production-ready agents from SOPs or plain-English goals, lowering the barrier to launching.; Single agent spans chat, SMS, WhatsApp, email, voice, and ChatGPT for consistent cross-channel support.; Outcome-based pricing ties cost to delivered results rather than seats.; Strong operational tooling for analytics, experiments, and observability of live agents.

**Limitations:** No published price list, so budgeting requires a sales conversation.; Enterprise-oriented positioning may be heavy for very small businesses.; Deep capabilities like Horizon and Context Engine assume integration with existing systems to reach full value.
