Studio & Canvas
One idea, every platform, in its own shape.
Studio drafts an idea for X, LinkedIn, Instagram and Threads at once, in the brand’s voice and inside each platform’s limits. Campaigns get a canvas where evidence, ideas and drafts sit side by side.

Harbor @tryharborThree weeks, two rewrites, one feature.
I kept it small on purpose: fewer moving parts, fewer surprises for the people using it. Honest note: the first version broke on mobile, so it shipped a week late.
What would you have cut?

Ideas that show their reasons.
Harbor suggests ideas from signals: how past posts performed, themes in replies, competitor posts and trends. Each suggested idea cites the signals behind it, so you can see why it’s on the list before you spend time on it.
- Reply themes become signals on their own
- Add your own ideas too, with an optional angle
- Ideas move along the pipeline: idea, drafting, approved, scheduled, live

Write once. See it the way each platform shows it.
Each platform gets its own pane: an editor, a live preview in that platform’s layout, and a counter against its limit: 280 on X, 3,000 on LinkedIn, 2,200 on Instagram, 500 on Threads. On X and Threads, a line of three dashes starts the next post in the thread.
- LinkedIn previews cut at “see more”, so you see the fold
- Instagram asks for an image or video first
- Post now asks once more before it sends

03Rewrites and versions
Another take, one click away.
Ask for hook variations, a shorter version, a punchier one or a more specific one. Variations come back beside the editor: use one, tweak it, and save it as a new version. Every version is kept, by Harbor or by you, and any of them loads back in one click.
- Hook variations change only the opener of a thread
- Versions are numbered and say who wrote them
- Nothing is saved until you choose to

04Campaign canvas
A canvas for every campaign.
Lay a campaign out on a board: frames for evidence, ideas and drafts, and cards for ideas, drafts, posts, notes and signals. Connect a post, a signal or a note to an idea and the agent drafts with them as context. The agent panel also suggests ideas into a frame and brings in top posts and signals.
- The same campaign as a board or a table
- Pull ideas, posts and signals in from the library
- The weekly plan can fill a campaign’s frames for you
