• 📝 Inline suggestions — see deletions, insertions, and replacements rendered inline with your document
• ✅ Accept/reject — review each suggestion
• 💬 Reviewer comments — every suggestion includes an explanation of why the change improves the text
• 🔧 Custom checks — run strikemd init to customize which checks you use

Install

Requires Bun.

bun install -g strikemd

Usage

strikemd my-essay.md

This opens a browser UI where you pick a check and model, run it, and review the suggestions.

Pass an API key with --key, the ANTHROPIC_API_KEY env var, or a .env file.

strikemd my-essay.md --key sk-ant-...

Other commands:

strikemd help       # show usage info
strikemd init       # create .strikemd/checks.md with default checks
strikemd -v         # print version

Built-in checks

• Remove redundant sentences — cut sentences that repeat a point or add no new information
• Hedge too-strong claims — qualify assertions that are stated too strongly
• Replace rhetoric with substance — swap emotional appeals for concrete statements
• Activate passive voice — rewrite passive constructions in active voice where it helps
• Clarify unclear sentences — rewrite ambiguous or hard-to-parse sentences
• Make the download explicit — turn abstract explanations into concrete frameworks

Custom checks

Run strikemd init to copy the default checks into .strikemd/checks.md. Edit that file to add, remove, or rewrite checks. Each # Heading becomes a check name, and the body becomes the prompt:

# Fix jargon

Find technical jargon that could be replaced with plain language. Rewrite for a general audience.

# Shorten paragraphs

Break paragraphs longer than 4 sentences into smaller ones.

When .strikemd/checks.md exists, it replaces the built-in checks entirely.
