SaaS Demo Script Builder
Describe one workflow in your product. Get a scene-by-scene demo script with narration, the screen each line needs and a timing estimate, plus checks for vague wording and claims you cannot show.
Fill in one workflow. Use what your product actually does today, not planned features.
Runs in your browser. Nothing you type is uploaded or stored. Timing assumes narration at 150 words per minute plus a 2-second hold after each action; rehearse it with the real clicks.
- Pairs narration with screen evidence. Each scene states what the viewer hears and what the product must show at that moment.
- One action per line. Steps that hide several clicks are flagged, so the narration never runs ahead of the picture.
- Shows the result instead of claiming it. Outcome claims and vague words are flagged unless you can support them with an approved source.
- Treat the output as a draft. Ask a product owner to check every action, label and prerequisite, then record with approved sample data.
What should a SaaS product demo script include?
Five parts, each with narration and the matching screen: the problem a specific viewer has, the starting point (account role or input), the actions in the product, the visible result, and one next step. An approved customer quote is optional and goes after the result. This tool writes those parts from your answers so you can check every line against the real product.
How long should a product demo video script be?
As long as one task takes to show clearly, and no longer. Read the narration aloud while you perform the clicks; that rehearsal is a better guide than a word count. The tool estimates time at 150 words per minute plus a two-second hold after each action. If the plan needs more than six actions, it is usually a tutorial, not a demo.
Is there a product demo script example I can copy?
Yes. Press "Try the sample" to load the fictional request-assignment example from FDM's demo script guide. It is a placeholder workflow, not a client's product. Replace every line with what your product actually shows.
Where does a customer testimonial go in a demo script?
After the demonstrated result and before the single call to action, and only if you have the customer's exact approved words and attribution. Do not write a quote for a customer. If there is no suitable quote, the tool leaves that scene out.
What does the tool check?
It flags vague words such as powerful, seamless and streamline, outcome claims such as hours saved or percentages that need an approved source, steps that hold more than one click, a missing visible result, a quote without attribution, and plans with more than six actions.
Is what I type uploaded anywhere?
No. The builder runs in your browser and does not send or store anything you type.
Can FDM turn the script into a finished demo video?
Yes. FDM edits screen recordings into product demos and UI walkthroughs for SaaS teams, including module-level walkthroughs for TikaMobile and interface-led explainers for Krista.ai.
