SASourceArc

A publishing workspace for source-led teams

One source.
Every channel,
in its own voice.

SourceArc reads the material you trust, then shapes it for each place you publish—without flattening every channel into the same generic post.

The workflow

From source material to publishable choices.

    Set the destination

    Choose channels, format, model, and credential.

  3. 03

    Keep editorial control

    Edit, regenerate, compare versions, and export.

Choice without guesswork

Use Gemini—or bring the model access you already trust.

Choose fast, balanced, or advanced models across Gemini, OpenAI, Anthropic, and OpenRouter.

Consumer API keys are encrypted, masked after entry, and never used as a silent fallback.

Generation history is preserved so you can edit, compare, restore, and understand how a draft changed.

Private beta

Bring the source. Leave with choices.
