Tag any prompt with #marketing #ai #template.
Filter across all workspaces by tag instantly.
Full-text search across every prompt in every workspace. Copy any prompt to clipboard in one click — or Ctrl+Enter after filling variables.
Live estimates of token count, word count, and character count per prompt — so you always know your prompt's footprint before pasting.
Tag each prompt with the AI model it's optimized for. Know at a glance which prompts are built for which model.
