A little magic

The enchanted monolith
that remembers.

Datalith is a monolith, enchanted to find and visualize every note you have ever written. A note is a pixel, a link between two notes another. Tend them, and the picture sharpens into focus: a private personal encyclopedia, one of a kind, built to outlast any app, service, or trend.

Datalith v1.0.0

Stable

Instant, every time

Opens in a blink, even on Vaults of 10k+ notes.
So reading and writing never wait on you.

Write in Markdown

Notes with preview, wiki links, and properties.

Tasks that stay files

A real todo.txt editor: priorities, projects, subtasks.

Local first

Your Vault is a folder you own, with open format files that outlive apps.
Your encyclopedia can never be taken from you.

Every thought, findable

Relevance-ranked search across names and content, as you type.
The right note surfaces even when you only half-remember it.

Ideas, connected by design

Wiki links become a living graph.
Follow a thread and rediscover what you forgot you knew.

Your notes, as databases

A .base file queries your Vault and renders it as a table, a list, a cards, or a graph.

Make it yours

Dozens of themes, light and dark.
Knowledge shaped into a familiar place is easier to come back to.
