Butter Editor

A WYSIWYG editing mode for Obsidian. Headings render as headings, bold is bold, embeds and callouts render in place. Your files stay plain markdown that every other Obsidian view and tool can read.

Butter is a paid plugin. Free 15-day trial, then $16 one-time for a lifetime license covering all v1 updates. No card, no email collected to start the trial.

What it does

Butter adds a fourth view mode alongside Obsidian's Source, Live Preview, and Reading. You toggle it per note. The file on disk never changes shape.

It renders the full Obsidian-flavored markdown surface in place: headings, bold, italic, strikethrough, lists, task lists, tables, code fences, math (inline and block), footnotes (reference and inline), highlights, wikilinks (all variants including aliases and headings), embeds (sized and standard), tags (including nested), block IDs, callouts (including nested callouts with code, math, or lists inside), and inline plus block comments.

Round-trip safety

Butter's job is to render your notes visually while leaving the source unchanged. A regression corpus of nearly 200 cases runs on every release. It covers the cases that tend to break naive WYSIWYG editors: nested callouts at multiple depths, code fences and math inside callouts, embeds inside list items, smart quotes and non-breaking spaces from Word or Google Docs paste, link labels containing inline atoms like tags or math, and CJK filenames in wikilinks. Your files round-trip through Butter cleanly.

Mobile

Mobile is the same plugin as desktop, not a port. Touch UX is purpose-built: long-press for the block menu, swipe drawers for block actions, native touch selection.

Other capabilities

Reorder blocks with a drag handle. On desktop the grip appears in the gutter on hover. On mobile, long-press a block.

Customize the toolbar to surface the actions you actually use.

Color text or apply colored highlights from the toolbar. Or keep your source pure markdown by turning off HTML formatting in Butter's settings.

A few more:

• Edit inline atoms in place. Double-click any wikilink, tag, embed, math span, or footnote and a small floating panel opens for editing.
• Insert any block type from the slash menu. Type / at the start of a block.
• Strip every styling mark from a selection with the clear-formatting button.

Type / at the start of a block for the slash menu.

Pricing

15-day free trial. No card, no email collected at trial start. After the trial, $16 one-time payment covers Butter Editor v1 forever, including all v1 updates. Up to 5 devices per license. 14-day no-questions refund.

When Obsidian's API eventually forces a major rewrite (v2), existing v1 customers get a discounted upgrade.

Network use and privacy

Butter talks to one set of servers, and only for license operations. Your note contents are never transmitted.

• https://api.buttereditor.com handles license validation, trial activation, session refresh, and device-list management. It's called when the License tab is opened, when a session token is near expiry, when you start or end a trial, or when you deactivate a device.
• https://licenses.buttereditor.com is your customer portal in a browser. The plugin opens it externally when you tap "Manage license". Nothing else uses it.

Requests go through Obsidian's requestUrl() so they're CORS-safe on mobile. There is no analytics service, no telemetry pipeline, no third-party tracker.

Butter stores what a license needs and nothing else: customer email, device list, license-key registry. The plugin runs locally. Full data-handling details are in the privacy policy.

Third-party code

Butter bundles two open-source libraries:

• ProseMirror (MIT), the editor toolkit.
• markdown-it (MIT), the markdown parser.

Their licenses are preserved in the compiled bundle. Everything else (the Obsidian-Markdown bridge, schema, serializer, NodeViews, and all features) is original Butter Editor code.
