What is Octopus.do?
Octopus.do's ChatGPT and Claude apps turn sitemap planning into a native LLM workflow, backed by an MCP server.
Octopus.do has been expanding its capability surface across three tracks: AI integration (official apps in ChatGPT and Claude, backed by an MCP server and public REST API), design handoff (Figma plugin generating high-fidelity, variable-based prototypes), and content editing (rebuilt editor with columns, tables, and text alignment; new copywriter team role). The most recent release adds project templates and a web crawl import that auto-fills pages with blocks and wireframes.
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's ChatGPT and Claude apps turn sitemap planning into a native LLM workflow, backed by an MCP server.
◆ Current state
Octopus.do has been expanding its capability surface across three tracks: AI integration (official apps in ChatGPT and Claude, backed by an MCP server and public REST API), design handoff (Figma plugin generating high-fidelity, variable-based prototypes), and content editing (rebuilt editor with columns, tables, and text alignment; new copywriter team role). The most recent release adds project templates and a web crawl import that auto-fills pages with blocks and wireframes.
◆ Where it's heading
The MCP server and REST API establish Octopus as a planning tool that AI agents can read and write natively, not just an export destination. The Figma plugin handles the downstream handoff; the editor rebuild sets up faster iteration on the core surface. Templates and crawl import are the obvious acceleration layer for teams using Octopus in AI-assisted site generation workflows — the pieces are connecting toward a pipeline where an AI plans the structure, Octopus holds the canonical information architecture, and Figma renders the prototype.
◆ Prediction
Octopus will deepen its AI integration — more agents via MCP, or native AI-generated sitemap suggestions — given the REST API and the earlier AI prompt export feature both point toward automated sitemap generation as a core use case.
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.
