OV review
A free, private Markdown workspace for offline notes and AI-assisted organization.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
OV is a free, local-first note-taking and organization app for individual users who want their notes stored as plain files on their computers. It supports Markdown notes, images, voice memos, tasks, and schedules, with desktop versions for macOS, Windows, and Linux. The core appeal is control over local files: OV combines offline operation with an open-source MIT license, while still offering structured views for tables, boards, calendars, and schedules.
Its feature depth goes beyond basic note capture. Full-text search, Wikilinks, backlinks, and graph view support connected knowledge work, while calendar and schedule management bring planning into the same workspace. AI-assisted note actions can propose changes for approval, giving users a review step before edits are applied. File-level AES-GCM-256 encryption adds a privacy-oriented option at the file level. For users who want local Markdown files alongside organization and AI assistance, this is a focused combination.
The platform fit is strongest for desktop workflows. OV currently covers macOS, Windows, and Linux, and iCloud Drive synchronization is intended for use across devices. Its listed integrations are iCloud Drive, OpenAI, and GitHub Releases, so it suits users who prefer a compact ecosystem over a broad integration catalog. Choose OV if local ownership, offline access, connected notes, and approval-based AI actions matter more than mobile availability or extensive integrations. Users seeking a wider platform and ecosystem footprint should consider an alternative.
