No permanent free plan, only a 14-day free trial
Entry-level Knowledge Base plan excludes the AI Suite entirely
Pricing is notably higher than lightweight knowledge base competitors

Company headquarters and team size are not clearly published
Logseq
Pros
Fully free and open source with no feature paywall
Local-first storage gives users complete data ownership and portability
Strong community plugin and theme ecosystem
Combines outlining, journaling, whiteboards, and spaced repetition in one app
Backed by notable investors, suggesting continued development funding
Cons
Steeper learning curve than mainstream note apps for users unfamiliar with outliners or Markdown
Multi-device sync requires the paid Sync add-on or manual setup via Git or cloud folders
Mobile apps have historically lagged behind desktop in polish and feature parity
Smaller company and team size than well-funded competitors like Notion
Plugin quality and maintenance vary since they are community-built
