Hi HN!<p>I have created a particularly realistic AI simulacra: <a href="https://kara.rhogpt.ai/" rel="nofollow">https://kara.rhogpt.ai/</a>. I haven't seen any LLM companies really explore this format.<p>Unlike other AI chatbots kara can receive multiple messages at once and send multiple messages at once. The personality is also pretty different from ChatGPT or Claude. It really is a lot like texting a friend.<p>Also I don't really like roleplay so kara does acknowledge it is an AI unlike friend.com and doesn't pretend it is anyone else unlike character.ai.<p>There might be some stability issues with the model (repeating messages, etc). It's made to appeal to younger people (gen-z) which might explain some design choices.<p>Let me know what you think! Thinking of making an app.<p><a href="https://kara.rhogpt.ai/" rel="nofollow">https://kara.rhogpt.ai/</a>
