/01
The problem

The challenge.

Most language apps quiz grammar and vocab but never let learners actually speak.

Real speaking practice requires speech recognition that tolerates accents and evaluation that is kind but specific.

The client wanted a learner-first experience with teacher and school portals behind it.

/02
The plan

Our approach.

Used Whisper for accent-robust ASR and a tuned LLM for grammar, fluency and pronunciation feedback.

Built a React Native app with role-play scenarios and conversation drills.

Added a teacher portal so tutors track student progress and assign focus areas.

Stored sessions with transcripts so learners can revisit and improve specific mistakes.

/03
The result

The outcome.

Learners practise speaking daily because feedback feels human.

Teachers see progress data instead of guessing.

Schools white-label the app into their existing curricula.

What partners
tell us.

Most clients renew for a second engagement. The ones who don't usually hire someone from our team to run the project in-house.

We are a mental health charity and not tech minded. We needed to improve our patient registration system but wanted a company that we can relate to. Hassan took the time to meet with me and patiently went through our process to find a personalised solution for us. Hassan's team did a great job streamlining our process and connected our registration system to our patient management software. Whenever we have a glitch, they resolve this quickly. Cloudini provides a personal and efficient service and we have adopted them to be our IT provider.

I am writing to wholeheartedly recommend Cloudini as a premier bespoke software development agency. Our journey with them has been nothing short of exemplary, far exceeding our initial expectations. While many agencies can develop based on strict specifications, Cloudini demonstrated an incredible commitment to our project that was truly unparalleled.

Dragonfly has been working with the team at Cloudini for several years now on building out our web-based platform and APIs. One of their strengths is quickly building out a multi-disciplinary team to work on the development and delivery of features with different technical requirements. Their support has allowed us to accelerate our development work without building an internal team. They have also worked seamlessly with other third parties both during the acquisition of Dragonfly and development of our mobile app. Cloudini has been instrumental in bringing our ideas to life and providing guidance to help us make the best technical decisions. I would recommend getting in touch with them if you're looking for support.
