Code-aware, local-first note-taking for IntelliJ-based IDEs. Capture snippets while you code, organize them in a three-level hierarchy (Notebook > Chapter > Note), and keep everything in a single SQLite file on your own machine — no cloud, no account, no telemetry.

Works with both Community and Ultimate editions. Requires IntelliJ IDEA 2023.3+ and Java 17+.

中文文档：README.zh-CN.md

A local-first notebook that lives inside your IDE. Notes are organized in a three-level hierarchy:

Notebook  >  Chapter  >  Note

Each note is a piece of text or code with optional description, source path, original offsets, and image attachments. Everything is stored in a single SQLite file under your home directory — no cloud, no account, no telemetry.

• Capture from the editor — Select text or code → right-click Add to Notebook (or Ctrl+\). Source file path and offset range are captured automatically.
• Insert back into the editor — Ctrl+Shift+\ or right-click Insert note into editor pastes a saved note at the caret.
• Three-level organization — drag rows within a table to reorder, drag a chapter onto another notebook to move it across, same for notes across chapters.
• Search — Alt+S in the editor opens a search dialog. Scopes: titles only, titles + content, titles + description, or full-text.
• Image attachments — JPG/PNG/GIF up to 10 MB. Thumbnails generated at 100×100 automatically.
• Import / Export JSON — Full round-trip backup of all notebooks, chapters, notes, and referenced images.
• Export as Markdown (single notebook) — Flat markdown file generated from a customizable Groovy template.
• Export as Markdown Tree (new in 1.41) — Every notebook / chapter / note written to a portable folder tree, one .md per note, with YAML frontmatter and _assets/ image folder. Ready to drop into Obsidian or Typora.
• Automatic database backup (new in 1.41) — Each plugin version upgrade copies your SQLite file to ~/.ideaNotebooksFile/backups/ before any schema migration. Last 5 backups are kept.
• Bilingual UI — English & Simplified Chinese.

1. File → Settings → Plugins → Marketplace
2. Search for Notebook
3. Install → restart IDE

1. Download the latest ZIP from JetBrains Marketplace or this repo's Releases page.
2. File → Settings → Plugins → ⚙️ → Install Plugin from Disk…

The database is shared across all IDE projects on the same machine — you always see the same notes. Only UI state (last selected item, pane visibility) is stored per-project.

File → Settings → Tools → Notebook

• Font & font size for code editor
• Thumbnail max size
• Restore last selection on startup
• Markdown export template (Groovy)
• Show "Add to Notebook" for empty selection

If you ever want to leave this plugin — or just want a portable backup — use the gear menu (⚙️) on the Notebook tool window:

• Export JSON — full database + images, for round-trip re-import later.
• Export as Markdown Tree — one .md per note, organized as <notebook>/<chapter>/<note>.md with an _assets/ image folder per notebook. Obsidian-friendly.

Nothing is locked in.

Requires JDK 21 (JBR 21 recommended; pinned by gradle.properties → org.gradle.java.home).

# compile + package
./gradlew build
# launch a sandbox IDE with the plugin installed            
./gradlew runIde
# run JetBrains Plugin Verifier (multi-IDE compat)           
./gradlew verifyPlugin     

The built plugin ZIP lands in build/distributions/.
