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

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。
