Exactly what I needed

I’ve been using this app since it came out. I’ve long wished for certain features and hoped for continued updates. It’s worked fine, however, the past 5 versions or so have finally given me the features I’ve been waiting for the whole time and it’s amazing. Separate system prompts, chat scoped system prompts,, toggleable parameters, more fixes to the streaming text Views, all the newer OpenRouter backend tool support. He even added COMPACTION! That’s amazing! Thank you so much! Love this app.

Excellent LLM client

I’ve been using local LLMs through openwebui for a while, but the lack of a proper iPad client makes the usability hard. Cumbersome is an excellent alternative to being able to access models you host on your own network. If you use VPN or tailscale, you’ll always have access to these models.

Great app!

I have looked around for different LLM API Clients for a while now and this one is definitely the best one I’ve tried by far. It has sync with iCloud so I can use it with my Mac, headless search (didn’t even know that was possible), and easy access to all the models you want (I use DeepInfra). Honestly can’t believe you give it away for free but I’m glad you do :)
