Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Take your prompt engineering workflow to the next level.
Spellbook is a professional prompt manager for developers, creators, marketers, and AI power users who want to organize, test, refine, and reuse their best prompts in one focused workspace.
Stop losing important prompts in Apple Notes, Slack, chat history, or random documents. Build a searchable prompt library designed for real LLM workflows.
WHY SPELLBOOK?
Writing prompts is easy. Managing them at scale is not.
Spellbook helps you treat prompts like reusable assets: organize them, version them, add variables, test them across models, and keep improving what works.
CORE FEATURES
Test Prompts Across Models
Connect your OpenRouter API key and run prompts against a wide range of leading LLMs. Compare outputs side by side and find the best model for each task, use case, or workflow.
Build Your Prompt Library
Save your best prompts in a clean, searchable library. Use folders, tags, and filters to quickly find the right prompt when you need it.
Reusable Prompt Templates
Create dynamic templates with variables like #{topic}#, #{tone}#, #{audience}#, or #{language}#. Fill them in when you run the prompt without rewriting the original.
Version and Refine
Track changes as your prompts evolve. Keep the versions that perform well, revisit earlier drafts, and improve your prompts over time.
Organize Complex LLM Workflows
Manage prompts for writing, coding, marketing, research, product work, automation, and AI app development from one dedicated workspace.
