Reor
Leading#2 in Open sourcemedium confidence
Private, local-first AI note-taking / writing app (~8.6k GitHub★). Writing-adjacent (PKM rather than pure copywriting) but a genuinely notable OSS tool.Our read
Why it ranks #2
Approximately 8.6k GitHub stars provide a meaningful adoption signal, though Reor is primarily a local-first knowledge app and only indirectly a content-writing tool.Here is the catch
writing assistance is secondary to personal knowledge management
local models and indexing add setup and hardware demands
smaller editing workflow than purpose-built writing suites
Does this well
keeps notes and embeddings local
useful research memory for long-form writing
open Markdown files reduce lock-in
Pricing
