I Built a Free Script Timing Tool Because I Was Tired of Guessing Video Length
When you're building a small SaaS product, the best ideas often come from solving your own problems.
That was exactly how ScriptTimer started.
As someone who creates YouTube videos and presentations, I kept running into the same issue: I'd finish writing a script that looked "about right," start recording, and realize it was two or three minutes longer than I expected.
Editing around that mistake wasted more time than writing the script itself.
So I decided to build a tool that could answer one simple question:
"How long will this script actually take to speak?"
The Problem
Word count doesn't automatically translate into speaking time.
Two people can read the same 1,000-word script at completely different speeds.
A technical tutorial might require slow delivery.
A promotional video might be much faster.
Simply dividing words by an average speaking speed wasn't enough—I wanted users to adjust the pace based on how they actually speak.
Building the MVP
The first version was intentionally simple.
The core features were:
- Paste your script
- Count the words
- Choose a speaking speed
- Instantly estimate speaking time
No login.
No account.
No unnecessary features.
I wanted people to get an answer in seconds.
Keeping Performance Fast
Because it's a utility tool, speed matters.
Users don't want loading screens just to calculate a few numbers.
While building ScriptTimer, I focused on:
- Minimizing JavaScript
- Compressing static assets
- Keeping the interface lightweight
- Reducing unnecessary dependencies
The goal wasn't flashy animations.
It was responsiveness.
SEO Was Part of the Product
One lesson I learned is that SEO shouldn't be an afterthought.
Instead of creating one homepage targeting every keyword, I built dedicated pages around specific user intent.
Examples include:
- Reading Time Calculator
- Words to Minutes Converter
- Speech Timer
- Podcast Script Timer
- YouTube Script Timer
Each page solves a different problem while supporting the overall product.
This approach has been much more effective than trying to rank a single page for dozens of unrelated keywords.
Shipping Before Perfect
Like many developers, I was tempted to keep adding features before launching.
Dark mode.
Accounts.
Analytics.
History.
Export options.
Eventually I realized none of those mattered if nobody was using the tool.
Launching early gave me something much more valuable than another feature:
Feedback.
Real users immediately pointed out things I hadn't considered.
Some wanted faster calculations.
Others wanted different speaking speeds.
Several requested additional calculators.
Those conversations shaped the roadmap far better than my assumptions ever could.
One Unexpected Benefit
The biggest surprise wasn't the tool itself.
It was how often people mentioned saving editing time.
Instead of recording a video, discovering it was too long, cutting sections, and recording again, they could fix the script before ever turning on the camera.
Sometimes solving a tiny problem creates a much bigger impact than expected.
What's Next?
I'm continuing to improve ScriptTimer by adding more creator-focused tools that help writers, presenters, educators, and video creators plan their content more efficiently.
The goal hasn't changed:
Remove small friction points so creators can spend more time creating and less time fixing avoidable mistakes.
If you're curious or have feedback, you can try the tool here:
I'd genuinely love to hear what features you'd build next or what challenges you've faced when planning video scripts.
