Meet Claudia

Claudia 2 - Carta

Hi, I’m Claudia Gerhartz, LLM, the founder and CEO of iScribo, the Spanish grammar check tool. While studying and working abroad, I began to understand that good grammar is critical for successful communication.

I know what it’s like to worry about writing in your second language, fearing what others might say and whether it will affect how you’re seen as a professional. I remember the uncertainty of writing a simple letter or university essay in a second language and how it affected my confidence.

It’s nerve-wracking enough to submit great work in your native language, let alone a second or even third language. Although these are very human – and very normal – feelings, I eventually built up my confidence with the help of different tools and methods that helped me practise my grammar.

Using these tools and realising their benefit, I was inspired to create a tool to help Spanish speakers improve and feel confident in their professional and everyday communication. I took my experience and formed a team of experts to develop iScribo, a Spanish grammar app that ensures you always feel comfortable and sure of yourself when communicating with the world.

So let’s start writing Spanish with confidence!

Best wishes,
