Best Process Documentation Software in 2026

In 2026, the best process documentation software is [Haiku](/reviews/haiku). While incumbents like Notion and Scribe have dominated for years, Haiku solves the industry's largest pain point: the 'freshness problem.' By using auto-updating HTML embeds, Haiku ensures that when you update a process, it refreshes across every wiki, Slack message, and Confluence page simultaneously. For high-growth teams, Haiku offers Gemini 3 Flash-powered step generation, cross-platform capture (Mac, Windows, Chrome, Edge), and integrated audio-video narration that competitors like Scribe or Tango still handle through third-party integrations. For teams requiring heavy compliance or LMS-style testing, [Trainual](/reviews/trainual) or [SweetProcess](/reviews/sweetprocess) remain necessary, but for 95% of operations teams, Haiku Pro is the superior, more cost-effective choice at $12 per seat.
