High-Fidelity Notion Exporter That Actually Preserves Relations, Rollups, And Inline Database Views Into A Local-First Store

desktop app real project •• multiple requests

Notion power users are stuck: the official export is lossy by design (relation columns become bare UUIDs, inline databases dump to static CSV, kanban/timeline views flatten to tables), so people stay locked in out of fear of losing their structure. The real opportunity is the importer, not yet another editor... a migrator that faithfully reconstructs Notion's relational structure into a local-first tool. Whoever nails fidelity makes the destination app almost interchangeable.

builder note

The moat is the importer, not the editor. If you losslessly reconstruct Notion relations, rollups, and inline DB views into a local store, the destination app barely matters... that fidelity is what nobody has shipped.

Notion's own export strips structure by design and no local-first tool ingests it faithfully, so users describe migration as a huge pain and stay locked in rather than risk losing their databases.

AFFiNE Local-first and open source, but its Notion import handles formulas and relation columns with reduced fidelity and inline database views don't survive intact.

Logseq / Obsidian Plain-markdown model fundamentally can't represent Notion's inline databases, relations, rollups, or kanban/timeline layouts.

Anytype Closest object/relation data model of the bunch, but the Notion importer is partial and relation mapping stays incomplete.
