NppAIAssistant
A lightweight AI assistant plugin for Notepad++

繁體中文

---

Visible prompts, modular single-turn profiles, and no hidden memory between requests.

This repository is focused on the plugin itself. It does not carry the full Notepad++ source history, which keeps the project easier to publish, review, package, and release.

Why It Stands Out

Feature	Description
Lightweight	Ships as a standard Notepad++ plugin with no core fork
Prompt visibility	Live preview of the exact prompt structure in settings
No hidden memory	Single-turn conversations with no cross-request context
Dynamic models	Model list loads after provider login or API key setup
Safer secret storage	Provider secrets now live in local DPAPI storage with legacy migration
Context menu	Practical right-click actions for editing workflows
Bilingual UI	English and Traditional Chinese support

Security and Settings Storage

• API keys and OAuth tokens are stored in %LocalAppData%\Notepad++\AIAssistant.
• Secret values are protected with Windows DPAPI.
• Non-secret preferences are stored separately in %AppData%\Notepad++\plugins\config\NppAIAssistant.ini.
• Legacy roaming secure blobs are migrated automatically on first launch of the updated build.
• Gemini requests now authenticate with the x-goog-api-key header instead of query-string API keys.
