Vihko

What Vihko is

Vihko is an AI-powered second brain for capturing ideas, connecting thoughts, and organizing information. Its Markdown editor supports note-taking through agentic chat, while AI suggests tags based on note content. Semantic search finds notes by meaning and context rather than keywords alone. The AI assistant can find and discuss subjects in a user's knowledge base.

Vihko is available on Android, iOS, macOS, web, and Windows. Its free plan includes limited note storage and AI features, with advanced search and organization and use across devices. The Basic plan costs $7 a month and adds unlimited note storage, AI chat with notes, full AI tagging and suggestions, MCP integration, and priority support. The MCP server connects notes with AI tools including ChatGPT, Claude, and Cursor; creating, reading, and searching notes through MCP requires Basic.

The maker says it does not sell personal data and processes and stores user content only as needed to provide the service. Its privacy policy describes reasonable technical and organizational measures, but does not guarantee absolute security. It states a commitment to GDPR and applicable Finnish and EU laws. Users must be at least 16 years old.

Who it suits

Vihko suits people who want to organize notes with AI-assisted tagging, semantic search, and chat grounded in their knowledge base. It also fits users who want notes connected to ChatGPT, Claude, or Cursor through MCP, provided they have the Basic plan.

Limits

The free plan has limited note storage and limited AI features. MCP integration's note creation, reading, and searching capabilities require the Basic plan.

Verdict
