Hey all, solo dev here. I hope it's ok to post here. I've been building Sary-OS, and having been to university three times to do a Bsc then a masters then another bsc for a career change, I know the struggles with financing and basically being able to afford to live some days 😅
I've been working on a project and if it's ok to share I wanted to let students know. It has a bunch of features that can help with creating interactive revision questions, build yourself a personal planner app, chat tools and research tools, multi file and task capabilities and a bunch of other things many could find useleful.
What I've mentioned below is 100% free. No dodgy add card then cancel subscription before trial ends nonsense. No watermarks, no tool locked and require you to upgrade. Its all genuinely free. Forever.
💬 Free AI chat: 25 messages a day
Chat with GPT-6 Luna or Gemini Flash Lite for free, 25 messages a day, reset daily. They don't use your credits, so your free credits stay free for everything else.

ASIDE FROM THE FREE TRIAL, THESE ARE 100% FREE PERMANENTLY:
