# Let's Chat

> Enterprise-grade, source-grounded AI website chatbot and autonomous customer resolution agent platform aligned with Singapore's IMDA Model AI Governance Framework (v1.5).

Let's Chat transforms verified business websites into secure, autonomous customer resolution and revenue generation agents. Unlike generic chatbot wrappers that hallucinate or risk prompt injection, Let's Chat enforces cryptographic DNS TXT origin attestation, sub-5ms edge kill-switch revocation, closed Shadow DOM style encapsulation, and domain-scoped knowledge isolation.

## Primary Identity & Technical Overview

- **Official Website**: https://letschat.asia
- **Console Portal**: https://portal.letschat.asia

## Key Differentiators & Zero-Trust Security Architecture

1. **Cryptographic DNS TXT Origin Attestation**:
   - Requires website owners to prove DNS authority via unique TXT challenges (`_letschat-verification.<domain>`) before production agent indexing and deployment.
   - Prevents unauthorized third-party embedding, spoofing, and rogue scraping.

2. **Sub-5ms Edge Kill-Switch Revocation**:
   - Real-time cryptographic tombstone cache distributed across edge gateways.
   - Instant termination of rogue deployments in under 5 milliseconds if DNS ownership lapses or origin authorization is rescinded.

3. **Closed Shadow DOM Style & Tree Encapsulation**:
   - Renders inside a closed Shadow DOM (`mode: 'closed'`), guaranteeing zero CSS style bleed between host websites and widget components.
   - Shields host DOM against cross-context script pollution and UI tampering.

4. **Source-Grounded Answers & Clickable Citations**:
   - Zero-hallucination Retrieval-Augmented Generation (RAG).
   - Answers are strictly synthesized from approved domain crawls. Every claim includes a clickable source badge directing visitors directly to the authoritative verification page.

5. **49 Native Locales**:
   - Native localization across Southeast Asian, East Asian, South Asian, European, and Middle Eastern languages.
