If bi-directional linking + Markdown are your two must-haves, I’d shortlist these:
Obsidian — Probably the closest match. Notes are stored as local Markdown files, and
[[wikilinks]]automatically create relationships/backlinks between notes. It also has graph view, block-level links, and a large plugin ecosystem.Logseq — Great if you like outlining and daily journals. It supports Markdown files, linked references, block references, and queries, with a more outliner-oriented workflow than Obsidian.
Zettlr — Worth considering if your notes are heavily research/academic oriented. It works directly with Markdown files and is designed around linked knowledge and writing workflows.
