Harbor is a document editor built for proposals, briefs, and case studies. Write in a focused workspace, publish as a branded reading experience, and see exactly how your clients engage — what they read, where they stop, and when they come back.
Write. Publish. Measure.
Three surfaces, one document. A focused editor for writing, a branded reader for clients, and analytics that show you what happened after you hit send.
Write
A focused editor with structured blocks for proposals, briefs, and recaps. Markdown, slash commands, and a bubble menu — never a toolbar in your way.
Share
Every document gets a real reader experience — on your domain, with your brand, table of contents, comments, and granular access. No more PDF attachments.
Measure
See who read what, where they stopped, what they highlighted. Treat your writing like product — with feedback loops, not silence after send.
Your proposal deserves its own page.
Every Harbor doc publishes as a real web page with your brand, a table of contents, search, and inline commenting. Clients read it in their browser — no downloads, no accounts, no friction.
- Reader templates — switch from minimal to studio without re-laying-out a single block.
- Granular access — public link, email gate, password, or a per-reader passcode that expires.
- Comments without accounts — clients leave inline reactions from a single link.
Know what your clients actually read.
Every published doc tracks views, scroll depth, time on each section, and reader reactions. Know if your champion opened it before the meeting — and which sections they skipped.
- Per-reader timelines — know if your champion actually opened it before the call.
- Section heat — the warmest scroll wins; the cold sections get cut next round.
- Slack & email digests — daily summary of who read what across every shared doc.
Blocks that mean something.
Outcome blocks define what success looks like. Project blocks reference live work. Every block is structured data inside your document — not just formatted text.
- Five typed primitives — Outcome, Skill, Project, Client, Pricing.
- One source, many docs — update a Project Block and every proposal that references it updates with attribution.
- Export to anywhere — CSV, JSON, or a webhook into your CRM the moment a client accepts.
Publish in one click. Version everything.
Set your access level, toggle analytics, and publish. Every publish creates a versioned snapshot — readers see what you shipped, not your latest draft. Roll back anytime.
- Custom domains on every plan — studio.yourname.com in one DNS record.
- Expiration & revocation — revoke a stale proposal without breaking the URL.
- Auto OG cards — previews built from your doc title, cover, and brand — ready for Slack and email.

Slack reader digests
A daily summary of who read what across every doc you've shared. Wires into your existing Slack workflow.
Harbor turned proposals from the worst part of running my studio into the part I'm proudest to send. The reader analytics changed how I follow up — I can see exactly when to call.
I stopped sending PDFs the day I tried it. Clients click the link, see a real page, comment inline, and we're talking about the work instead of formatting.
