Hi everyone, I'd like you to try out Karja - a privacy focused local-AI powered superapp. Karja combines a bunch of useful apps for your everyday work into one single app which works completely offline on your own laptop or desktop machine. It uses private web search backends (your own Brave API key or a locally hosted SearXNG instance), a local AI backend (currently oMLX - for Apple Silicon users - and Ollama are supported) and cross-app synergies to supercharge its apps. Karja is available on Mac, Windows and Linux.

Right now the free version comes with these apps : Web Search (private search), Documents (for pdfs) Notepad (rich text editing), Kanban (project todo-lists), Calendar, Places (Weather + Clock), Slides (markdown presentations) and Numbers (Unit Conversions + Calculator). The Pro version in addition to all the free apps include : Charts (for visualizing data), Draw (diagrams), Sheets (XL sheets), Scanner (OCR), Gallery (Photos with local face detection and AI tagging) and Collage (accurate ranking of photos and automatic collage creation). Some apps are wrappers around popular OSS libs like Excalidraw with an integrated persistence layer. In the future, I have a lot more apps in the pipeline for both the Free and Pro tiers. Karja provides a unified AI chat interface which can pull in contexts from your local app database and also the web. It also provides a built in summarizer, which can provide detailed summaries from the provided contexts. More advanced LLM driven knowledge bases (and apps based on that) are being actively worked on. Also more app synergies and cross-app functionality are in the pipeline.

The Pro version is an LTD (lifetime) offer, and this is a decision that is dear to my heart. I believe more software should be made available with a one-time fee only, with all future updates included forever. Hence, Karja Pro will never have a subscription-based model. Privacy is also one of my core pain points with subscription based AI providers, so I've deliberately kept away from supporting cloud API providers. I believe local AI is only going to get better in the future, and thus Karja's AI features will also benefit with time, as a result. Also since Karja works completely offline (apart from your own private web search backend if you need it), there's no data collection from the user, and hence no user profiling. As a long time CS researcher and software developer - I've developed Karja with ideas and learnings that I've accumulated over decades, and use-cases from my own everyday work.

I'd be grateful if you could give it a try and gave me some honest and constructive feedback. Bug reports and feature requests aside, I'd like to know what kind of apps you'd really like to see integrated in such an app. And of course, happy to take any questions.

Thanks a lot.
