About LeanPrompts Studio
LeanPrompts Studio is a professional, local-first Integrated Development Environment (IDE) designed for prompt engineers and AI developers. It lives directly inside your browser, allowing users to build modular templates, chain reasoning steps, and inject prompts into LLMs without incurring additional API token costs.
Key Features
- Modular Global Snippets (@): Manage personas and frameworks centrally; reference them anywhere with @ to propagate updates globally.
- Dynamic Templates ({{Variable}}): Decouple logic from data with placeholders that automatically render interactive sidebar inputs and dropdowns.
- Unified Knowledge Base: Organize guidelines and notes using autocomplete wikilinks [[ ]].
- Local-First Architecture: All data is stored locally in your browser's IndexedDB sandbox, ensuring your intellectual property stays on your machine.
- Zero Token Costs: Operates on top of existing web interfaces, avoiding premium API-middleman billing.
Pricing & Plans
- Local Core ($0/forever): Includes unlimited local templates, dynamic sidebar forms, multi-step chains, and offline support.
- Team Hub ($15/seat/mo): Adds shared template registries, BYOC sync, and team collaboration features (minimum 3 seats).
- Enterprise Guard (Custom): Includes GPO deployments, data exfiltration guards, and priority SLA support for corporate networks.
Frequently asked questions about LeanPrompts Studio
Do I need to pay for API keys to use LeanPrompts?+
No. LeanPrompts operates on top of your existing browser sessions, meaning you do not need to purchase API keys or pay per token.
Which browsers are supported?+
The extension is compatible with all Chromium-based browsers, including Google Chrome, Microsoft Edge, Brave, Opera, Vivaldi, and Arc.
Is my data stored securely?+
Yes. LeanPrompts uses a local-first architecture where all prompts, variables, and notes are stored within your browser's IndexedDB sandbox and never leave your machine.
How does this differ from a standard text expander?+
Unlike text expanders, LeanPrompts is an intelligent orchestrator that parses variables into sidebar forms, bypasses React state-locks to inject text, and handles local file uploads.
