Questions & Answers

As answered by people managing Speechable.co and Vapi.

Which are the primary technologies used for building your product?

Speechable.co's answer

Next.js, React, TypeScript, Supabase, Tailwind CSS

How would you describe the primary audience of your product?

Speechable.co's answer

Students and academics who want to listen to PDFs, research papers, and textbooks. People with ADHD, dyslexia, or visual impairments who need audio as a primary way to engage with text. Anyone who wants to turn documents into something they can learn from on a commute, at the gym, or away from a screen.

Who are some of the biggest customers of your product?

Speechable.co's answer

Students and researchers from prestigious universities.

Why should a person choose your product over its competitors?

Speechable.co's answer

Unlimited playback with natural AI voices for free (competitors limit free plans to robotic voices or daily caps). Up to 50% accessibility discount with no verification required. A $7 one-time credit pack instead of yet another subscription. Privacy-first: no data training, no data selling, and Eco Mode processes everything locally. Content clean-up that strips document noise so listening actually works for academic papers and reports.

What makes your product unique?

Speechable.co's answer

Eco Mode runs text-to-speech locally in your browser, making playback unlimited, free, and 20x more energy-efficient than cloud alternatives. Speechable also cleans up document noise (footnotes, citations, ads, page numbers) before converting to audio, so you hear content, not clutter. And instead of just reading documents aloud, it transforms them into podcasts, lectures, and conversations you can chat with in your own language.

What's the story behind your product?

Speechable.co's answer

Speechable was built by a product engineer based in Tokyo who was frustrated with existing document-to-audio apps. The voices sounded robotic, the audio was full of footnotes and page numbers, and the good features were locked behind expensive subscriptions. He wanted to build something better: a tool that actually cleans up documents before reading them, uses natural AI voices, and makes the whole experience accessible to students and people with disabilities without gatekeeping.

That's why Speechable has Eco Mode (unlimited free playback), trust-based accessibility discounts, and a $7 one-time credit pack instead of forcing another monthly subscription.
