Why bring your own provider

Model choice

Use the model family, subscription mode, or compatible endpoint that fits your interview or meeting workflow.

Cost visibility

Keep external AI billing tied to provider accounts you already manage instead of bundled credits.

Pricing separation

Review ExtraBrain pricing to compare app workflow controls separately from provider account costs.

Operational backup

Configure a tested fallback so quota, availability, or local hardware limits do not derail a live session.

Feature

Provider model comparison

Bundled AI plans

Some assistants sell access to selected hosted models inside their own subscription. That can be convenient, but pricing, quotas, and model choice are tied to that vendor.

BYO providers

ExtraBrain emphasizes provider access you control, including local Gemma 4 where installed and compatible and external accounts or subscriptions when cloud models fit the task.

Retention boundaries

With BYO providers, review your provider account settings directly because retention, logging, training, and billing are governed outside ExtraBrain.
