About

Bias Writer

Features
Read full description

BIAS Writer is a markdown editor for novelists, note-takers, journalists, and students who want a clean, focused writing environment. A minimal interface that gets out of your way. Write in dark or light mode. Organize with projects, documents, and tags. Archive what you're not using. THREE TOOLS YOU WON'T FIND ANYWHERE ELSE Memos ((double parentheses)) — Leave yourself notes that stay visible while you write but never appear in exports. Research links, reminders, questions to resolve later. Omits [[double brackets]] — Keep alternate lines, deleted scenes, or backup text in your document but hidden from your final output. Cut without losing. Tags #hashtags — Mark chapters, status, characters, or anything you want to track. Filter your entire project instantly. SEARCH ACROSS EVERYTHING Find any word across all your documents. Switch to Memos, Omits, or Tags mode to search only those. Jump directly to any result. EXPORT CLEAN Share as Markdown, PDF, HTML, or plain text. Memos and omits are stripped automatically — or include them if you want. SYNC WITH iCLOUD Subscribe to sync your writing across iPhone, iPad, and Mac. Your work is always with you. FREE TO TRY Write for 7 days. Subscribe to keep your work synced across devices.
