As a high school student, I love LLMs and the execution of Apple's Appel Intelligence Writing Tools, but was disappointed that nothing like that existed for Windows. I thus created Writing Tools, a better than Apple Intelligence open-source alternative that works system-wide on Windows. It's much better than the tiny 2B parameter Apple Intelligence model!
Features (works system-wide): 1. Select text in a textbox, press the hotkey, and optimise your text in a click (proofread, rewrite, tone changes, custom instructions...). You can also select code to fix/refactor it with the custom instructions. 2. Press the hotkey without selecting any text to bring up a chat UI with the LLM. 3. Select all text on a webpage, press the hotkey, and use the Summarise button to get summary of the webpage/text!
It can use the free Gemini API, or a multitude of local LLMs via Ollama, llama.cpp, KoboldCPP, TabbyAPI, vLLM, etc.
It's completely free & open source, and is heavily privacy-focused (local LLM support, your API key stays on-device, no logging, no tracking, etc.)

Writing Tools has also been featured on XDA, Beebom, Windows Central, Neowin, and more! :D
P.S. This is my first major Windows coding project, so I'm especially keen on advice for best practices and potential improvements! Thank you so much for your time :)
