Public chat

The shortest path from a finished graph to real users: enable the channel on the Deploy tab, take the link, hand it out. No markup, no hosting.

Enabling it

1. Open the scenario → Deploy tab → Web channel.
2. Set a welcome message — it is shown before the visitor’s first line.
3. Press Deploy: the channel serves the deployed version, not your draft.

The link carries the scenario’s public token. Anyone holding it can talk to the bot, and the runs are billed to the workspace owner — treat it as a publication, not a secret.

Files from a visitor

Out of the box the chat takes text only. The Allow attachments switch in the same channel turns on the paperclip in the composer and dropping a file straight onto the window: a visitor can send a photo, a voice message or a document, and the scenario can read them with the speech-to-text, vision or document-parsing nodes.

The setting is shared with the widget — one conversation with two doors. Images, audio, PDF (up to 8 MB) and text files are accepted, up to ten per message. Only a model with document input reads a PDF: on any other the turn stops with an error instead of answering without having opened the file. What is uploaded lives in your storage (the Files section, under the session’s folder) and counts against your plan’s quota, so turn it on where the scenario actually needs the files.

Sessions and memory

Every visitor gets their own session: histories do not mix, and a memory node in the graph sees only the current conversation. The transcripts are in Clients.
