These two apps solve different writing jobs. Boulevard is a solo desktop app for getting pages down without a subscription. WriterDuet is built for people who need to share one live file — two people writing at once, comments, and a monthly plan when the room is real. Neither is universally better; the fit depends on whether anyone else is in the draft.
Both tools understand industry screenplay layout. The fork is where the draft lives and who can touch it while it is being written. One person in a quiet desktop app is a different product from two people revising the same scene in real time.
Boulevard is an offline desktop app for solo drafting. The page stays quiet so the writer can keep moving; the editing view stays close to the PDF, and the toolset stays intentionally lean rather than packing every suite feature into the sidebar.
The writer who wants a desktop app that stays light, keeps nearly every writing feature free, and exports a clean PDF with no watermark.
There is no live editing from two people in the same file and no monthly co-writing room. If two people must type in the same file at once, this is the wrong tool for that hour of the day.
Mac and Windows. Free covers five local documents. Premium is $45 once for unlimited documents, cloud save, extra themes, and dark mode.
WriterDuet is built around real-time co-writing. Live co-editing, comments, and chat make it a natural home for partners who revise together instead of shipping dated files back and forth.
Co-writers who need one living file with two people writing at once, and who accept a monthly plan when that room is real.
A writer who only ever works alone and does not want a subscription attached to a solo draft will usually find the wrong bill. Free intentionally stays off the full desktop app until the paid tier begins.
Free is browser- and phone-first. Paid plans start around $9.99/mo (Pro and Premium sit higher) and bring a desktop app, offline access, and the full live-room experience.
