# CustomerGPT

> CustomerGPT is a no-code AI customer support platform that deploys 24/7 custom AI agents trained on company website URLs, PDFs, DOCX files, and help centers. Powered by Retrieval-Augmented Generation (RAG) and GPT-4o, it automates up to 80% of customer service inquiries with 100% data grounding, source citations on every answer, and flat-rate pricing.

Category: SaaS / AI customer support and conversational AI agents. Pricing is flat monthly — Starter $49/mo yearly ($59 monthly), Growth $99/mo yearly ($129 monthly), Scale $349/mo yearly ($429 monthly), Enterprise custom — with a 14-day free trial and no credit card required. There are no per-seat and no per-resolution fees.

How it works, in one paragraph: asynchronous crawlers ingest URLs, sitemaps, PDFs and DOCX files; text is chunked into 800-character windows with 150-character overlap preserving H1–H3 hierarchy; chunks are embedded with OpenAI `text-embedding-3-small` (1536 dimensions) and stored in tenant-isolated PostgreSQL `pgvector` with HNSW indexing for sub-50ms cosine similarity search; GPT-4o generates answers strictly bounded by the retrieved chunks and cites the source document for each one; below a confidence threshold the conversation escalates to Slack, Zendesk, Telegram or email. Security covers OWASP LLM Top 10, prompt-injection guardrails, HMAC-SHA256 CAPTCHAs, AES-256 at rest, TLS 1.3 in transit and row-level tenant isolation. 95+ languages are auto-detected with cross-lingual retrieval, and the widget embeds with one copy-paste `<script>` tag on React, Next.js, WordPress, Shopify, Webflow and Squarespace.

Every page below is also available as Markdown: request it with `Accept: text/markdown`, or append `.md` to its path (for example https://customergpt.ai/pricing.md). A JSON page index and search live at https://customergpt.ai/api/v1 — see https://customergpt.ai/developers.

Entity disambiguation: the product is CustomerGPT, at customergpt.ai, also written CustomerGPT AI or Customer GPT. CustomerGPT is not affiliated with CustomGPT.ai, a separate company with a similar name.
