No special syntax and no elaborate workflow builder. Baby Whale reads the material, does the work with tools, checks the result, and saves it to your workspace.

  1. 01

    Bring the source material

    Upload spreadsheets and documents directly to the conversation.

  2. 02

    Describe the outcome

    “Clean this data, find the story, and build the review deck.”

  3. 03

    Baby Whale does the work

    It reads, writes code, creates the files, and checks the output.

  4. 04

    Open the deliverables

    Everything lands in a local folder you control.

Local by architecture

Your work stays yours.

Baby Whale has no cloud account, file storage, or telemetry pipeline. Your workspace stays on your disk. You choose the model provider and supply the key.

See the setup →
01

Files stay on your machine

Uploads, scripts, sessions, and deliverables live inside local workspace folders.

02

Your API key

Use DeepSeek, OpenRouter, or another compatible provider. Baby Whale does not proxy your model traffic.

03

No Baby Whale account

No sign-up, no sync service, no remote file store, and no product analytics pipeline.

Get started

Working in a few minutes.

You need Node.js and an API key from your preferred provider.

1

Start Baby Whale

npm i -g @haifai/bwhale

Then run bwhale — the @haifai/bwhale package installs the bwhale command. The first start fetches the runtime once and opens 127.0.0.1:24680.
