Slide deck presentations and retellai?

Support Help

Hey guys,

I have a pitch deck and want to see if there is a native way via retell to get the AI to present and go through the pitch deck with the prospect, so takes them slide by slide and then they can ask questions? Any solutions for this or custom build?

Thanks,
Chris

Hey @chris1

There’s nothing native for this. Retell is voice only, it has no visual layer and no way to control what’s on someone’s screen. So the deck side is on you. Good news is the syncing part is not hard if you run it as a web call.

The shape that works: put the deck on your own page, embed a Retell web call on that same page, and let the agent talk while your page does the showing. Then pick how the two stay in step.

  1. Conversation flow agent, one node per slide. The web SDK fires a node_transition event when the agent moves node, so you listen for that and advance the slide. Cleanest option and it is documented: Make browser-based web calls with the Retell Web SDK . I have not checked the exact payload shape myself, log it once and you will see what you get.
  2. A custom function like show_slide(number). The agent calls it, your backend pushes the change down to the browser over your own websocket. More plumbing, but you get exact control, and the agent can jump back to slide 4 when someone asks about pricing.
  3. Cheap version, listen to the update event and match a phrase in the transcript. It works, but it is brittle and I would not ship it.

For the questions part, load the deck content and your usual objection answers into a knowledge base, then give each slide node a way to answer and come back. A flow handles the wander off and return pattern better than a single prompt, because the current node stays as your anchor.

One thing worth sorting early. If you want this over the phone there is no visual at all, so you would be emailing the PDF first and having the agent say “slide 3 now”, which is a much worse experience. Is this browser based or phone?

Hello @chris1 There’s no native “pitch deck presenter” feature in Retell, but you can build this effectively using two approaches:

Best approach: Conversation Flow
Use Conversation Flow to build a structured, slide-by-slide experience. Each slide becomes a Conversation Node with the slide’s content as the prompt/script. Transitions move the agent to the next slide after the prospect responds or confirms they’re ready. This gives you full control over the sequence while allowing free-form Q&A within each node.

Supporting it with a Knowledge Base
Upload your pitch deck (.pptx or .pdf supported) to a Knowledge Base and attach it to the agent. This lets the agent answer deeper questions about any slide’s content beyond what’s scripted.

In short: It’s a custom build, but Retell’s Conversation Flow + Knowledge Base combination is well-suited for it — no third-party tools needed.
