Prompt Builder
Prompt Builder is a shared AI prompt library for your team. Write a good prompt once, mark the parts that change as blanks, and everyone can reuse it by filling those blanks in instead of rewriting the whole thing.
Use Prompt Builder together on your board.
It sits on a shared MockFlow board next to your work. Every prompt saved there is there for everyone on the board, with who wrote it. Open one, fill the blue blanks right inside the sentence, and copy the finished prompt into ChatGPT, Claude or any other AI tool.
- Fill in the blank prompts. Blanks appear as blue fields inside the sentence, so you always see what the finished prompt will say.
- Choice lists. Give a blank a set of choices, such as a tone or an audience, and people pick one from a dropdown.
- Text box or form. Write freely in one box, or build the prompt as a form with Role, Task and Format. Empty form fields are left out.
- Shared with everyone on the board. Every saved prompt is there for the whole board, with the author's name, and anyone who can edit the board can change it later.
- Your answers remembered. What you typed into a prompt's blanks is kept for you only, so the next time you open it, your last answers are already there.
- Search. Find a prompt by its name or by any word in it.
- Delete with undo. Delete a prompt from its editor and bring it back with Undo.
- Private public view. Someone opening the board from a public link sees the prompts without any names and cannot change anything.
