## What it is
Eidos is a local-first, single-file relational spreadsheet built on standard SQLite, usable from a desktop app, browser editor, or agent-first CLI. It combines typed tables, relations, formulas, and multiple views (grid, kanban, gallery, etc.) in one portable .eidos file that both humans and AI agents can read and modify.

## Use cases
- manage structured personal data in a single portable file
- replace Notion or Airtable with a local-first offline alternative
- let an AI agent create and update relational databases via CLI
- build typed tables with relations, formulas, and multiple views
- query and edit SQLite-backed spreadsheets from scripts
- work offline with local-first data that syncs optionally

## When to choose
- you want a Notion-like relational database that works fully offline
- you need a single portable SQLite file as your data format
- you want AI agents to safely manipulate structured data with typed operations
- you prefer local-first tools without mandatory accounts

## When to avoid
- you need real-time multi-user collaboration out of the box
- you require a fully hosted managed database service
- you need non-SQLite data backends or heavy enterprise features
