VSPromptBase
PromptBase is a marketplace designed for selling. Prompt Builder is a workspace designed for creation.
- No "Black Box" Fees:
Keep your prompts. We provide the tools to build them, we don't tax your creativity.
- Real Engineering Tools:
Variables, logical blocks, and testing environments are missing from marketplace upload forms.
VSNotion
Notion is great for docs, but it's not prompt-aware. Prompt Builder understands the structure of AI instructions.
- Live Token-Aware Preview:
See exactly how your prompt assembles in real-time, stripping away the "document" formatting.
- Direct Model Testing:
Don't copy-paste to ChatGPT. Test your prompt blocks directly within the builder.
