TextDeck for Claude users
Claude shines on long-form, nuanced prompts. TextDeck is where those prompts live between sessions.
The pain
Long, carefully-crafted prompts are too valuable to lose
Your best Claude prompts are 200-500 words with careful framing, constraints, and examples. Typing one from memory every time is a waste.
Claude Projects are great but not everywhere
Projects are a Claude-specific feature. If you want the same prompt in ChatGPT or Gemini for comparison, you are back to copying and pasting.
Variables make long prompts practical
A 400-word prompt with {{topic}}, {{audience}}, and {{constraints}} is reusable. The same prompt without variables is a one-off you rebuild every time.
Three TextDeck workflows
The long-form analysis prompt
Build a deep analysis template with {{document}}, {{focus}}, {{output_format}}. Hit ⇧⌘P, fill fields, paste into Claude. You get consistent, structured output without rewriting the 300-word system prompt.
Multi-step reasoning templates
Claude is great at following explicit reasoning steps. Build templates that spell out each step — "First X, then Y, then Z" — with variables for the inputs. Reuse across topics.
Constitutional / style-constraint templates
Templates that include Claude-style constraint blocks ("Do not X. Always Y. If unsure, ask.") for consistent behavior across conversations.
Example prompt templates
Deep document analysis
You are an expert {{role}}. Analyze the following document for {{focus_areas}}. Output format: {{output_format}}. Be specific, cite sections, and flag anything ambiguous.
Document:
{{document}}Multi-step plan
Help me plan {{goal}}. Step 1: identify constraints. Step 2: list assumptions. Step 3: propose 3 approaches with tradeoffs. Step 4: recommend one. Context: {{context}}.Critical review
Review the following {{content_type}} critically. Identify weak claims, unsupported assertions, and places where reasoning breaks down. Be direct but constructive.
{{content}}FAQ
Does TextDeck work with Claude Projects?
Yes. TextDeck produces the prompt text; you paste it into any Claude interface, including Projects, claude.ai, or the Claude API playground. No integration needed.
Can I store Claude Projects' system prompts in TextDeck?
Absolutely — many Claude power users do exactly this. Build your system prompts as TextDeck templates with variables for the parts that change per project.
Will TextDeck ever call Claude directly?
Direct API integration is not the current focus. TextDeck is intentionally model-agnostic: you paste the output into whichever Claude (or other model) surface you are using.
