Eidos Lite · Your local data workspace

Shape your data around the way you think.

Build a personal library, research tracker, content calendar, or anything in between. Switch between Grid, Gallery, and Kanban, then let an AI agent work safely through Eidos CLI when you need automation.

One local file. Every useful view.

Eidos Lite · Multidimensional workspace. Keep typed fields, relations, formulas, files, and ratings together. Switch views without exporting data or changing its source of truth.

Ownership by design

Real ownership is more than an export button.

An open format
Eidos File is described by a public, versioned specification, so its structure is not defined by one app or hidden behind a private API.
Read the Eidos File 1.0 spec
One transparent file
Each .eidos file is SQLite. Inspect it with ordinary SQLite tools, copy it, back it up, or move it without waiting for a platform export.
Open SQLite Web Viewer
History you can actually use
Git usually sees only a changed SQLite binary. Graft is designed for SQLite structure, with table- and row-level review plus whole-Space restore.

Built for the AI era

One workspace where you and your agents can both work safely.

You edit visually in Eidos Lite. Agents use a first-class machine interface to understand structure, make validated changes, and leave reviewable evidence in the same files.

01

You · Visual or CLI

Work visually in Eidos Lite or Web Editor, or launch the same editor locally from your terminal when you prefer the CLI.

01

Eidos Lite

The main Eidos experience: local folders, multidimensional SQLite files, row-aware version history, and optional Sync.

02

Web Editor

Open and edit a local .eidos file in your browser. No account, no install, and nothing uploaded.

03

Build locally with eidos serve

Create a typed Gallery, explicitly mount its local assets folder, and open the shared editor on localhost. Eidos CLI is available on macOS, Linux, and Windows.

Gallery with local assets · macOS / Linux shell 

mkdir -p assets

eidos create gallery.eidos \
  --table Gallery \
  --label-field Name \
  --fields '[{"name":"Name","type":"text"},{"name":"Attachment","type":"file"}]'

eidos serve gallery.eidos --assets-dir ./assets --open

02

Your Agent · Eidos CLI

Eidos CLI exposes typed mutations, revision checks, and validation. Eidos Skill teaches compatible agents the workflow; Graft keeps the result reviewable.

Eidos CLI

Graft · Structured history for SQLite

See every change. Return to any checkpoint.

Graft records SQLite table and row changes as a timeline you can review and restore.

See exactly what changed before you save.

Compare changed files and row values, whether the edit came from you or an agent.

Optional Sync

Start local. Connect your devices when you are ready.

Lite and local history work without an account. Sync is an invite-only beta that adds hosted continuity across your own devices—nothing more.

Local-first core

Eidos File and local tools

Create, edit, automate, and version files you control. No account or hosted service is required.

$0 forever

Eidos Sync · Invite-only Beta

Hosted continuity

Official Graft Remote with 10 GB account-wide storage and unlimited personal devices under reasonable use.

$5 / month

$49 / year

Join the waitlist to request access. Approval is granted in batches; until then, Sync stays off and local files remain fully usable.
