Reproof lets writers swap paragraphs effortlessly without rewriting entire drafts from scratch.

Linear writing still feels outdated, like old typewriter habits clinging to modern workflows. When drafting for sites like Zapier or Wirecutter, writers often hit the same block: they want to test three opening styles without losing the original draft. Editors usually force choices—delete the alternatives or bury them in forgotten graveyard files.

Reproof was built to change that by treating documents as versioned blocks instead of rigid pages. Each paragraph can exist in multiple states, and toggling between them lets you see which version fits the piece’s flow instantly. It’s a non-linear tool designed for writers who prioritize precision over perfectionism.

The tool’s key features address drafting frustrations directly:

• Paragraph Versioning: Generate new paragraph drafts and swap them live without waiting until the end.
• Clipping System: Save paragraphs that don’t fit yet but aren’t worth deleting entirely for later use.
• Format Compatibility: Supports rich text, Markdown, and HTML seamlessly, with clean copy-pasting between formats.
• Side-by-Side Editing: Research or notes stay open in one pane while drafting in another—no more switching tabs.
• Keyboard Shortcuts: Everything is accessible through commands to minimize context-switching.
• Human-First Proofing: Errors surface without AI-driven rewrites, letting writers control the prose while the AI assists.

Developing this required overcoming technical challenges. Four core engine rewrites were needed before the versioning felt snappy, even with Tiptap. Reinventing the editor wasn’t optional—non-linear workflows demanded a fresh approach.

To adopt Reproof, reframe paragraphs as modular components rather than a single, unbreakable stream. When a sentence feels stuck, avoid deleting it outright. Instead, create a new version and test a different angle. This approach turns perfectionism into experimentation, letting writers shape their thoughts freely.
