What each one is
claude-obsidian
claude-obsidian is a plugin for Claude Code that works with Obsidian, a note-taking app. You drop sources such as articles, papers or notes into an inbox folder, and Claude reads them, writes linked notes with source references, and files them into one connected graph of plain Markdown files stored on your own computer. It is based on Andrej Karpathy's LLM Wiki pattern as described in the README.
Claude SEO
Claude SEO is an open-source plugin for Claude Code, Anthropic's coding assistant. You point it at a website and it runs an SEO audit covering technical health, content quality, structured data, and how likely AI search tools are to cite your pages. The README says a full audit takes 10 to 15 minutes and ends with a prioritized action plan. It is built from 26 sub-skills and 19 specialist agents.

Strengths
claude-obsidian
- Notes stay as plain Markdown files on your computer, with no telemetry described in the README
- Originals in inbox/ are kept untouched so summaries can point back to sources
- MIT licensed and free, with a health-check skill for keeping the vault tidy
Claude SEO
- Free and MIT licensed, with the source code public on GitHub
- Covers a wide range of SEO areas in one tool, from technical checks to AI search and reporting
- Commands are documented in the README with clear descriptions
Not ideal for
claude-obsidian
- People who do not use Claude Code, since the plugin is built for it (other hosts are listed but need extra setup)
- Windows users who want to write to the vault natively, since the README says WSL is needed for writes
- Anyone wanting a hosted, cloud-synced note app, since the README stresses local files and no cloud database
Claude SEO
- People without Claude Code, since the README presents it as a Claude Code plugin
- Users who need live search data without setting up optional extensions, which the README describes as separate and optional
- Anyone expecting guaranteed rankings; the README makes no such promise and the audit is advisory
Trade-offs
claude-obsidian
- Requires Claude Code and Python 3.11 or newer, so it has setup costs and an ongoing AI tool dependency
- The README says Windows writes need WSL, which adds friction on that platform
- The README's own feature list is long (15 skills, 3 agents); some pieces are optional and not fully explained in the truncated text
Claude SEO
- Requires a Claude Code setup, so it is not a standalone app
- Optional extensions for live SEO data are extra setup beyond the core plugin
- Results shown in the README, such as traffic numbers, are from the project's own site and are not a general guarantee
