Our philosophy
We want local-first AI to be the norm.
Everyday work shouldn't cost a monthly fee or your privacy. Karja lets anyone work with their private documents and a local LLM - without subscriptions, and without handing data to anyone.
Private by default
Your documents stay on your machine and talk to your own locally installed LLM. Nothing is sent to large AI companies - ever.
No profile of you
Karja’s web search asks for no account and builds no profile of you. Route your queries through a privacy-first engine or your own self-hosted server. No-one to mine your searches and serve you targeted ads.
No forced updates
Karja never forces an update on you. Update manually when you want newer features - never because you're told to.
Better over time, on its own
Karja runs on your own AI backend, and local models keep getting better. Swap in a newer one and your summaries and suggestions sharpen - no new version of Karja needed.
Yours for life
Karja is a lifetime-deal app. Buy once and it works forever on your machine. No subscriptions, no recurring fees.
A true superapp
Apps share one private workspace and build on each other, creating synergies an assortment of separate tools never could.
Own your tools. Own your data.
Download Karja, plug in your local LLM, and get to work - privately, and for life.
