esa
Markdown-based team knowledge sharing service built around the concept of 'growing information.' WIP culture lets people post drafts freely — a favorite among Japanese startups and engineering teams.
Jake's editor noteThe 'it's OK to publish WIP' philosophy fits Japanese engineering culture. Great for building a small team's doc habit at a fair price — but weak for multilingual/overseas use.
English UI?
Japanese only, no English interface.
vs Notion?
esa: document/knowledge-focused and simple. Notion: database flexibility and page customization.
Free option?
No permanent free plan, just 2-month trial.
