Note-taking apps have been around for as long as apps themselves.

But thanks to the rise of AI and the massive availability of APIs like OpenAI's GPT-4 and Whisper, hundreds of use cases have been unlocked, and smarter, more useful note-taking apps pop up every day.

One of the apps in this space that we admire is AudioPen by Louis Pereira.

AudioPen is an app that lets you transform messy notes into clear text. Just hit record and speak your mind, then AudioPen will turn your rambling thoughts into neat notes instantly.

Louis has been using Senja to power the testimonial collection and sharing of AudioPen, and today we're interviewing him to see how he does it.

Why were you looking for a testimonial tool?

I'd been looking for an advanced testimonial tool for AudioPen, and Senja seemed like a good bet.

Before using Senja, I didn't have a testimonial widget that I could customize on each page of my website. As a result, I'd only showcase testimonials on a dedicated page. Now, I display them everywhere.

Without a dedicated testimonial tool, using testimonials across your site can be difficult. It gets even harder when you need to manually find relevant testimonials for dozens of marketing pages on your website. Senja makes it easy to share your testimonials at scale.

How do you currently collect testimonials and how often do you collect testimonials?

Currently, I have a link within the website for people to leave a testimonial. I also collect social proof from Twitter, LinkedIn, and Product Hunt by importing it into Senja.

How are you using Senja to get more sales and increase conversion?

Besides using Senja on the AudioPen home page, I also use a differently-themed testimonial widget on the upgrade page. This helps in boosting the conversion rate from free to paid accounts. I haven't measured it, but I'm pretty sure I've seen an increase in conversion.

I also love Senja's image creation tool. I use it to create shareable images of testimonials I've received. The best part about these is that they allow me to upload custom backgrounds which helps maintain brand consistency.

I like a lot of things about Senja, but what I like the most are its testimonial widgets. They're customizable, and make it really easy to showcase social proof on the AudioPen website. They load quickly and I can display over 50 testimonials with barely a second's loading time.

I'd highly recommend Senja; it's well worth the cost considering the benefits it brings along. Also, their team is pretty great!
