I was skeptical about the value, but after spending a couple of weeks with it, I will not go back. It's way more convenient than loading up a browser and jumping into ChatGPT or Claude. Creating prompts and linking them to keyboard shortcuts and the LLM I want to use has been huge! I have a professional coach prompt with Opus, a summary prompt with GPT-4, and a coding prompt with Gemini Pro, all with instant access via hotkeys! Also, I love that large context prompts from the clipboard are pasted via a "clipboard object", rather than scrolling through 200K lines!
Best way to describe this Thinkbuddy is to AI as Superhuman is to email!
