I Built primarily using models from @AnthropicAI. However, I’m now completely unable to use any of the models to continue working on this app due to the extremely aggressive censorship and “guardrails” implemented. I have a premium subscription to Claude Code and Cursor. I’m curious to know if @cursor_ai or @AnthropicAI can provide a solution to allow me to continue using Anthropic models to develop legitimate security software products. Alternatively, I’d appreciate any recommendations you may have.

Literally guyss u need to check this 🤯 Hey guys, I was getting really annoyed with all those "free" online tools that compress images or merge PDFs but then force you to create an account or pay a premium fee to download your file. Also, uploading sensitive documents to random servers always felt sketchy to me. So, I built a collection of 9 web tools that process everything 100% locally in your browser. No data is ever uploaded to a server, there are no signups, and it's completely free.
