# datajoi

> datajoi puts a team of semi-autonomous data agents on your stack — ingesting, modeling, cleaning, and validating around the clock. You don't manage pipelines: you curate the business knowledge base (metrics, definitions, business rules) that tells the agents what "revenue," "active customer," and "good month" actually mean. Built for SMBs and teams without a data team.

Key facts:
- The division of labor: agents handle connecting sources, building and repairing pipelines, modeling raw data, running validation, tracking lineage, and flagging drift; you handle the knowledge base — your metrics, definitions, and business rules
- Semi-autonomous by design: agents propose, act, and self-check, but the definitions they run on are always yours; human-in-the-loop by default, with a full audit trail
- Knowledge base as first-class truth: define a metric once and every agent, query, and DataStory obeys it — permanently and consistently
- DataStory™: ask a question in plain language, get an answer backed by the exact SQL underneath — trust it and check it, no black boxes
- Agents check their own work: schema checks, freshness, row-count drift, and lineage verification run automatically; failures arrive with a fix already proposed
- 500+ data connectors, powered by dlt, DuckDB, and Apache Arrow
- Built natively on DuckDB and DuckLake: open formats, ACID-compliant, portable by default, point-in-time travel and immutable snapshots — no vendor lock-in
- Chrome extension: an in-browser data analyst with local execution — files never leave your machine (free trial, then paid)
- Pricing: platform — Pro $99/mo, SMB $999/mo (up to 10 users, most popular), Enterprise custom (contact hello@datajoi.com); Chrome extension — free trial then paid, Pro tier pricing announced soon
