What is Octopus.do?
Octopus.do integrates with Claude and ChatGPT via MCP, turning sitemaps into live AI-editable workspace.
Octopus.do is a sitemap and content-planning tool used by UX designers and content strategists. Its most directional move in recent months is an official Claude and ChatGPT integration with an underlying MCP server: you can now ask an AI assistant to build or edit a sitemap directly inside your Octopus account. This follows a Figma plugin that generates high-fidelity prototypes from sitemaps, reinforcing Octopus as a connective layer between planning and execution tooling. Google Analytics integration (September 2026) brings live page-view data into the planning canvas.
What is Pencil2D?
Pencil2D's 0.7.1 candidates are mostly about not losing the user's work
Two release candidates for 0.7.1, twenty months apart, plus the earlier 0.7.0 candidate. The substantive changes are data-integrity fixes — a ClipboardManager memory leak, frame data loss when copying bitmap keyframes, project recovery dialog improvements, backups on polyline completion — alongside macOS codesigning and notarization and a reworked toolbox layout that reflows into rows or a single column.

Octopus.do
6.3DESIGN
Octopus.do integrates with Claude and ChatGPT via MCP, turning sitemaps into live AI-editable workspace.
◆ Current state
Octopus.do is a sitemap and content-planning tool used by UX designers and content strategists. Its most directional move in recent months is an official Claude and ChatGPT integration with an underlying MCP server: you can now ask an AI assistant to build or edit a sitemap directly inside your Octopus account. This follows a Figma plugin that generates high-fidelity prototypes from sitemaps, reinforcing Octopus as a connective layer between planning and execution tooling. Google Analytics integration (September 2026) brings live page-view data into the planning canvas.
◆ Where it's heading
Octopus is positioning itself as the structured planning layer that AI agents, designers, and content writers all touch. The MCP server + Claude/ChatGPT apps extend the tool from human-only to agent-addressable; the Figma export closes the gap between planning and visual design; Google Analytics closes the gap between planning and live performance data. The new Copywriter project role suggests the team is investing in team-scale workflows where different contributors (copywriters, designers, SEO editors) need scoped access.
◆ Prediction
Octopus will expand the AI surface—likely adding agent-driven SEO tag generation, AI-assisted sitemap restructuring based on analytics data, or deeper Figma round-trip editing. The public REST API and MCP server hint at a platform play: Octopus as structured sitemap infrastructure that third-party tools and agents can read and write.
Pencil2D
0.0DESIGN
Pencil2D's 0.7.1 candidates are mostly about not losing the user's work
◆ Current state
Two release candidates for 0.7.1, twenty months apart, plus the earlier 0.7.0 candidate. The substantive changes are data-integrity fixes — a ClipboardManager memory leak, frame data loss when copying bitmap keyframes, project recovery dialog improvements, backups on polyline completion — alongside macOS codesigning and notarization and a reworked toolbox layout that reflows into rows or a single column.
◆ Where it's heading
For a hand-drawn animation tool the recurring subject is protecting in-progress work, and that is where these candidates spend their effort. The platform work sits alongside it: signed and notarized macOS builds and an updated Qt6 runner are the cost of shipping a desktop app users can install without warnings.
◆ Prediction
A general 0.7.1 release is the natural next step once the candidate cycle settles, though the twenty-month gap between candidates makes timing hard to call.
