Voice PDF vs a Loom walkthrough of your deck
Last updated · Pitchline
Short answer
Recording a Loom of yourself walking through your deck is the most common way founders explain a deck asynchronously, and it works. The limits: the video says the same thing to every viewer, it can't answer questions, and you have to re-record it whenever the deck changes. A Voice PDF from Pitchline is presented live by an AI agent each time someone opens it, so viewers can interrupt with questions and you see what each of them asked.
Comparison
| Loom walkthrough | Voice PDF (Pitchline) | |
|---|---|---|
| Explains your deck | Yes, in your face and voice | Yes, an AI voice agent following your talk track |
| Answers viewer questions | No | Yes, out loud |
| Same content for every viewer | Yes | No, it responds to what each viewer asks |
| After a deck change | Re-record | Upload the new PDF |
| Jump to what the viewer cares about | Scrub the timeline | Ask the agent |
| Shows what the viewer wanted to know | Views and watch time | Time per slide plus every question asked |
| Qualifies the buyer | No | Yes |
| Personal touch | High, it's really you | Lower, it's an AI agent in your framing |
When a Loom is better
For a short, personal note to one high-value prospect, a 90-second video of you is hard to beat. Faces build trust.
When a Voice PDF is better
For the full deck walkthrough that goes to many prospects, gets forwarded to stakeholders and changes as your deck changes. Plenty of founders do both: a 30-second personal Loom intro, with a Voice PDF linked underneath for the full walkthrough and questions.
