Q2 2026

Share documentation, not logins

Create interactive project portals with Mermaid diagrams, Markdown, and HTML pages. Invite clients via a single magic-link — no sign-up, no password, zero friction.

The Problem

Sharing docs with clients shouldn't require a project management degree

Google Docs isn't structured

Sharing documentation via Google Docs or Dropbox gives clients a flat folder of files. No hierarchy, no branding, no context for where to find things.

Notion requires client accounts

Full project management platforms force your clients to create accounts, learn a new tool, and navigate a complex interface just to view your deliverables.

Feedback gets lost in email

Client feedback scattered across email threads, Slack messages, and shared documents. No way to anchor comments to specific content or track decisions.

Solution

One link, full context, branded experience

Magic-Link Guest Access

Invite clients via a single token URL. No sign-up, no password, no friction. Guests view content, leave comments, and react instantly.

Context-Aware Comments

Both providers and guests can comment and react with emoji. Comments can be anchored to specific Mermaid diagram nodes for focused, in-context discussions.
