01 / The everyday experience

Familiar for your team.
Clear for your business.

BisChat is the private AI chat workspace inside PrivateStack: the everyday chat window your team opens to ask questions, draft, and search your own documents, with the models, the retention, and the audit trail under your control.

  1. Ask, draft, and move forward.

    Use a familiar chat workspace to ask questions, summarize material, and prepare a first draft.

    Example to explore in a walkthrough

    Summarize the renewal terms in this vendor agreement.

  2. Work from your own sources.

    Bring your documents and knowledge bases into the conversation, so your team can work with its own material.

    Example to explore in a walkthrough

    Find the relevant sections in our internal policy documents.

  3. Keep the work reviewable.

    Requests record who asked, when, and which model responded. Administrators can export the trail for review.

02 / The business controls

Useful AI.
With decisions you own.

Make the choices behind your team’s AI use visible: the models, the data handling, and the records available for review.

Choose the models

Administrators decide which open models each workspace can use.

Set the retention

Choose how long conversations are retained. Hosted inference uses a disclosed zero-retention subprocessor.

Export the records

Get a complete, exportable request trail to support your own review process.

Solo & Team

A hosted workspace.

Each team gets its own provisioned workspace. Hosted inference runs through a disclosed zero-retention subprocessor.

Compare hosted plans

Enterprise

Your own AWS account.

The full stack runs inside your own AWS account and VPC. AWS is the cloud supported for Enterprise BYOC today.
