Veritas Howler - Note Proofreader

Veritas Howler - Note Proofreader

Select a passage in a note and let an LLM check it for factual errors. Your own wording is kept; only what is actually wrong gets fixed. The corrected passage dissolves into ink particles and re-forms in place, changed spots are marked with a soft gray ==highlight==, and a short teacher-style note appears right under the passage: what you got right, or what was wrong and why.

Usage

• Right-click → Veritas Howler → Review: asks for optional extra instructions (remembered for next time), then reviews. Leave it empty to fix factual errors only.
• Double-tap Alt (Option ⌥ on Mac): reviews the selection immediately, facts only, no dialog.
• Right-click → Veritas Howler → Remove highlights: strips the == markers in the selection and keeps the text.
• Nothing asks for confirmation. Ctrl/Cmd+Z undoes a whole review in one step. With no selection, nothing happens.

While waiting, the selection shimmers softly. When the result arrives:

• The passage dissolves into particles and re-forms with the corrections; press Esc to skip the animation.
• If nothing needed changing, the passage flashes green twice.
• A frosted-glass card under the passage gives the verdict: the key point you got right, or what was wrong, why, and the correct idea, plus at most one pointed remark. Close it with the round × in its corner.

The command palette also has Review (facts only), Review with extra instructions, Remove highlights in selection, Cancel the running review, and Demo animation (no API call) (inserts a sample passage and plays the correction without calling any API; one Ctrl+Z removes it).

Installation

• Community plugins (once listed): Settings → Community plugins → Browse → search "Veritas Howler".
• BRAT (for pre-releases): install BRAT, then Add beta plugin → jiwawang/obsidian-note-proofreader. BRAT keeps it updated.
• Manual: download main.js, manifest.json and styles.css from Releases into <vault>/.obsidian/plugins/note-proofreader/, then enable the plugin.

Requires Obsidian 1.13.0 or later. After enabling, pick a provider and add your API key in the plugin settings.

LLM providers

The default is any OpenAI-compatible endpoint, with presets for inexpensive options:

You can also switch to Anthropic Claude (default Claude Opus 5; more expensive, more reliable checking).

Settings

Network use and privacy

• Each review sends the selected passage and the surrounding note text (about 20,000 characters by default, adjustable) to the provider you configured: DeepSeek, Google, OpenRouter, Anthropic, or your custom URL. Nothing else is sent, and there is no telemetry.
• You supply your own API key and pay your provider directly. The key is kept in Obsidian's secret storage, not in your vault files.
• Checking relies on the model's own knowledge; it does not search the web. When the model is unsure, it leaves the text alone.

Build from source

npm install
npm run build

npm run dev rebuilds on change.

中文说明

选中一段笔记，让大模型检查其中的事实性错误。以你的原话为准，只改确实错的地方。修正后的段落会化成墨色颗粒、再在原处重新聚成；改动处写入浅灰色 ==高亮==（设置里可改为浅蓝或主题默认色）；段落正下方出现一张毛玻璃卡片，像老师一样告诉你：哪里对、对在哪，或者哪里错、为什么错。

• 右键 → Veritas Howler → 审阅修改：可填写额外要求（会记住上次内容），留空则只修正事实错误。
• 双击 Alt（Mac 上是 Option ⌥）：直接只修正事实错误，不弹窗。
• 右键 → Veritas Howler → 取消高亮：去掉选区里的 == 标记，保留文字。
• 都不需要确认；不满意 Ctrl/Cmd+Z 一步还原。没有选中文字时什么都不做。
• 默认使用 DeepSeek（OpenAI 兼容接口），也可切换 Gemini、OpenRouter、自定义接口或 Anthropic Claude。
• 每次审阅会把选中段落及周围笔记内容发送给你选择的服务商，除此之外不发送任何数据；API key 存在 Obsidian 密钥库中，不写入仓库文件。
• 界面语言跟随 Obsidian：Obsidian 设为中文时显示中文，其余语言显示英文。
• 需要 Obsidian 1.13.0 及以上。
