How Onuri autonomously extracts structured knowledge from unstructured writing without manual bracket syntax or tag maintenance.
| Your Goal / User Objective | How Onuri Natively Executes It |
|---|---|
| Connect notes automatically while typing | Onuri parses natural writing on-device to identify people, places, dates, times and topics, then makes them available as connected terms and filters. |
| Eliminate manual [[wiki-links]] and brackets | Identifies named entities directly from standard text without requiring custom syntax or markdown formatting. |
| Rediscover related past thoughts effortlessly | Home-screen filters narrow entries by recognised people, places, dates, times and topics; selected terms can be combined and connected terms can be followed. |
| Retrieve vague or partially remembered details | Combines full-text search, recognised filters and related entries based on similar meaning to help resurface partially remembered notes. |
| Uncover recurring life themes and relationships | Optional Premium Insights surface momentum, streaks, recurring themes, people and place patterns, semantic clusters and strongest connections. |
