LeanPrompts Studio

=== 🎛️ THE COMMAND CENTER (FEATURE ARSENAL) ===

LeanPrompts gives you absolute control over your AI interactions. It is built as a complete workspace:

• 📦 Smart Variables {{ }}: LeanPrompts parses your templates and automatically generates custom sidebar input forms. Use {{Name}} for text inputs and {{Tone: Professional|Creative}} to build instant dropdown menus.
• ⚠️ Required Fields {{! }}: Enforce input safety. Prefix a variable with an exclamation mark (e.g., {{!Target_Audience}}) to block injection and highlight empty fields in amber until you fill them out.
• 🧱 Modular Snippets with @: Stop repeating identical instructions (like brand guidelines or coding rules). Save them as global Snippets. Type @ inside the editor to reference them. Any update to a central snippet propagates globally across all dependent templates.
• ⛓️ Prompt Chains: Break down highly complex tasks into logical phases (e.g., Step 1: Extract, Step 2: Critique, Step 3: Format). Inject each step one-by-one to force structured, hallucination-free AI reasoning.
• ⚡ Smart Modifier Injections: Click to inject into your current chat, Ctrl + Click to force a fresh new conversation, or Shift + Click to open your target assistant instantly.
• 📎 Local File Dropzones {{file: ...}}: Type {{file: SourceCode}} anywhere in your prompt to generate a local dropzone. LeanPrompts constructs native DataTransfer sequences to upload your PDFs, images, or documents programmatically, inserting the exact filename directly into your text.
• 🤫 Secret Comments: Keep internal developer notes, prompt testing instructions, or explanations inside your workspace. Use standard %% obsidian %%, // line, or /* block */ comments—LeanPrompts strips them out before injection so the AI never sees them.
• 📚 Built-in Knowledge Base: A Markdown-capable second brain for your prompt engineering. Document model quirks, save best practices, and use autocomplete [[WikiLinks]] to connect notes. Supports unencrypted local image embeds.
• 🌓 Native Split-Screen: Align the LeanPrompts workspace and your AI assistant side-by-side with a single click. The window manager programmatically splits your display to eliminate overlapping windows.
• 🕒 Version History, Diff-Viewer & Snapshots: Automatic snapshots protect your baseline before major edits. Review changes via a Git-style character-level code diff viewer and restore older versions instantly.
• 🛡️ Workflow Hub & Import Rollback (1-Click Undo): Shared workflows can be exported as unified Workflow Bundles (JSON). When importing external bundles, the Smart Merge Engine auto-detects namespace conflicts (appending an "imported" suffix) and offers a 1-click Rollback to cleanly reverse any import.

=== 🔒 PRIVACY, SECURITY & TRUST (100% LOCAL-FIRST) ===

LeanPrompts is designed for professionals handling NDAs, proprietary code, GDPR requirements, and sensitive client data:

• No Cloud Servers: LeanPrompts has no external database. Your prompts, templates, snippets, and histories live exclusively inside your browser's secure local IndexedDB sandbox.
• No API Keys: It operates purely on top of your existing browser sessions. No credentials to leak, no data routed through external middleman servers.
• 100% Offline Local AI Support: Working with highly confidential data? Connect LeanPrompts to local, offline Web-UIs. LeanPrompts explicitly permits unencrypted http:// connections for loopback/localhost IP ranges to keep your workflow fully offline.
• RAM-Guard Protection: A built-in 100MB batch limit on file attachments prevents browser Out-Of-Memory (OOM) crashes during Base64 serialization.
