Think. Build. Grow.

We built two language-technology products from zero and grew them ourselves. Same team, same engine, now working for translators and language schools.

Who we are

A software company that ships its own products

Nefosfer is an R&D company based at Gazi Teknopark in Ankara, Turkey. We build language technology, and the two products we sell are our own: we wrote the code, ran the launches and paid for the marketing out of our own pocket.

That matters for one reason. When we tell a translation agency or a language school how a tool behaves under real workload, we are describing something we operate ourselves, not something we resell.

Products

Two products, one language engine

Both went from idea to production inside our own team. They share an AI layer and split at the interface.

Translation technology

A teaching tool for students, a CAT tool for professionals

Linguaiser serves two audiences with the same engine: people learning translation and interpreting, and translators doing the work every day.

For education AI-assisted exercises and review flows for translation and interpreting programmes.
For professionals Enough CAT tooling to run daily translation work, with AI suggestions built in.
  • Translation memory and glossary
  • AI translation suggestions
  • Consistency checking
  • Instructor and student flows

Language teaching

Builds all four language skills together

Reading, writing, listening and speaking move forward on one programme. Teachers use it inside the lesson, students continue outside it, and progress is visible per skill rather than as a single score.

In class Exercises that fit the lesson flow, with live progress for the teacher.
Outside class Homework assignment, submission tracking and automatic assessment.
  • Four skills together
  • In class and at home
  • Skill-level reporting
  • Branch and institution management

Why us

Built by the people who answer your questions

There is no reseller layer and no outsourced development. The team that wrote the product is the team you talk to.

We write the code Development is in-house. Feature requests go to the people who maintain the codebase, not through a partner network.
AI where it does work Translation suggestions, terminology consistency, exercise generation and assessment. Defined steps with defined inputs, not a general chatbot bolted on the side.
An R&D company We operate inside Gazi Teknopark. Scope gets written down before code gets written, and the smallest version that does the whole job ships first.
We run what we sell Both products are live and operated by us. The setup we recommend to you is the one keeping our own business running.
Common questions

Frequently asked

What the products are, who they are for and how to get started.

Ask us directly
What does Nefosfer do?

We build AI language technology. Linguaiser serves translation and interpreting: teaching tools for university programmes and a full CAT tool for working translators. Learnaiser is a teaching platform for language schools that develops reading, writing, listening and speaking together. We also run digital growth services, currently for the Turkish market only.

What is the difference between Linguaiser and Learnaiser?

Linguaiser is for translation work and translator training: translation memory, terminology, consistency checking and AI suggestions. Learnaiser is for language teaching institutions: in-class exercises, homework assignment and skill-level reporting. They share the same underlying AI layer but serve different users.

Can I buy the products on this site?

No. Nefosfer is the parent company and this site introduces the products. Pricing, demos and sign-up run through each product's own site: linguaiser.com and learnaiser.com.

Do you work with organisations outside Turkey?

Yes for the products. Linguaiser and Learnaiser are used remotely and onboarding is done online. Our digital growth services are currently offered in Turkey only; that part of the site is in Turkish.
