SmartPrompt

Advanced Prompt Engineering Platform

SmartPrompt was born from a need I discovered while building DocumentFlow. I added secure workspaces with Clerk, real-time token counts via tiktoken, live OpenAI API testing, and one-click exports into LangChain–ready templates—all wrapped in a Next.js + Tailwind UI.

Secure Developer Workspaces

I integrated Clerk for login, roles, and personal prompt vaults so each user gets their own private space.

Live Tokenization & Testing

Using tiktoken + live OpenAI calls, I built real-time token analytics and a test harness for prompt tuning.
