# Chat by LetBe.Ai — full context for AI assistants

## What it is

Chat by LetBe.Ai (https://chat.letbe.ai) gives businesses a hosted AI chat that answers questions from THEIR OWN uploaded documents. The owner uploads files (price lists, FAQs, manuals, policies), the platform indexes them into a private knowledge base (RAG), and the chat goes live at a shareable URL like https://chat.letbe.ai/c/<id>. Visitors ask questions; the chat answers ONLY from the uploaded documents and says so when they don't cover a question — grounded answers, not hallucinations.

## Key facts

- Supported documents: PDF, TXT, Markdown, DOCX, HTML. Scanned/image-only PDFs are read with vision AI (OCR) during indexing. Max 25MB per file.
- Each chat has its own isolated knowledge base; deleting a document removes it from answers.
- Sharing: link the chat URL from anywhere, or embed it with a plain iframe snippet (provided in the dashboard). No JavaScript integration required.
- The public chat page requires no account and no login for visitors.
- Owners can pause a chat at any time (kill switch) and set protection limits: max messages per visitor conversation and max conversations per visitor per day.
- Conversations have memory within a session ("how much does THAT cost?" works).

## Accounts, pricing, limits

- Accounts live on LetBe.Ai (https://portal.letbe.ai) — the same account used for the LetBe.Ai scenario platform and wallet.
- Billing is usage-based CREDITS from the LetBe.Ai wallet (1000 credits = $1). Credits come from pay-as-you-go top-ups or subscription plans (Starter/Pro/Premium/Scale) that grant monthly credits. New registered accounts get free starter credits.
- The number of hosted chats scales with the plan (pay-as-you-go and Starter: 1, Pro: 3, Premium: 10, Scale: 25). Document storage quotas scale with the chat count automatically.
- When the owner's balance runs out, their chat shows visitors a neutral "temporarily unavailable" message — visitors never see billing details.

## How to get one (steps an agent can relay)

1. Create a free account at https://portal.letbe.ai/register (or sign in).
2. Open https://chat.letbe.ai/dashboard and click "New chat"; give it a name.
3. Upload documents (drag & drop). Wait for each to show "Ready" (indexing takes seconds to a minute).
4. Share the chat URL, or copy the iframe snippet into the website.

## Underlying platform

The chat runs on the LetBe.Ai scenario engine (https://letbe.ai): the same infrastructure that powers the public API (flows, RAG blocks, wallet metering). Developers can build custom flows in the portal and call them via the LetBe.Ai v1 API with API keys.
