A meeting where the AI can talk and show beats one where it can only talk. Present File gives your AI persona a stack of artifacts it can pull up on screen — a deck during a pitch coaching session, a contract clause during a negotiation roleplay, an X-ray during a clinical scenario, a product demo video during onboarding. The AI decides when to show what based on the conversation, using a present_content tool. The file appears in the meeting as a video-overlay surface that both the participant and the AI can reference.
Present File works in Waterr meeting rooms (meeting links, the playground, the embedded widget). It is not available when the agent joins a Google Meet, Zoom or Microsoft Teams call or answers a phone call — there is no screen to show it on. In those calls the AI isn’t offered the tool; if asked to show a file, it says it can’t share its screen and describes the content out loud. The files still work as Knowledge Base entries.

​
Setting it up

1

Open your scenario

Switch to the Settings tab in the scenario builder.
2

Open the Present Files section

This is a separate section from Knowledge Base — same Settings tab, different list.
3

Upload your files

Drag-and-drop or pick from your computer. Each file gets a name and a short description — the AI uses the description to decide when to show that file.
4

Steer when to present (optional)

In your scenario’s prompt, mention the file name or describe a trigger (“when they ask about pricing, show the pricing sheet”). The AI follows the cue.

​
Supported formats and limits

Files marked as presentable are also indexed for retrieval — they double as Knowledge Base entries. If you want a file searchable but never shown on screen, attach it to Knowledge Base instead.

​
Use cases

Pitch Coaching

The AI investor pulls up your real pitch deck slide-by-slide and asks pointed questions per slide.

Contract Negotiation

The AI counter-party shows the disputed clause on screen mid-conversation.

Clinical Training

The AI patient case shows X-rays, charts, or lab results when the trainee asks for them.

Product Demo

The AI sales rep plays a 30-second product video instead of describing the feature in words.

​
How the AI decides

The AI sees each file’s name and description. During the meeting, when the conversation reaches a point that matches a file’s purpose, it calls the present_content tool with that file’s ID. The file appears on the meeting screen as a video overlay; the AI then narrates over it or asks the participant to react to it. You can guide this in your scenario’s prompt:
In your prompt: “After the participant introduces themselves, show them the company-overview.pdf before asking your discovery questions.”
Without explicit prompt instructions, the AI presents files opportunistically based on conversation drift.

​
Participant-uploaded files

Files uploaded by the participant during a meeting (via the in-call chat surface) are read into that session’s context — the AI can reference them in the current call but they are not added to the scenario’s Present File list. Use this when a participant needs to share a resume, a screenshot, or a doc the host didn’t pre-load.
  • Knowledge Base — silent retrieval from files; the AI cites without showing
  • Vision — the inverse direction: the AI sees what the participant shows
  • In-Call Chat — for files the participant uploads to the AI during the meeting
