Building a TUI was easy before, especially with the great toolsets for their respective languages BubbleTea / Textualize / Ratatui. And thanks to those frameworks, LLMs can manifest useful tools.

Similar to WebApps, it's only since the November'25 renaissance that I felt I could use them to create TUIs. Once I had that revelation, I started going into my backlog and using it.

I maintain a TUI Charting library, NTCharts. In January, I fixed a bug - totally obvious once identified - that I personally failed to find earlier. But the test harness, prompting, and Gemini got it done [1]. Gemini's spatial understanding was critical in completing the task.

I've been vibe-crafting a local LLM conversation viewing tool called thinkt. After scraping ~/.claude and making a data model, this is the point in PROMPTS.md where I start creating the TUI using BubbleTea. [2].
