Comparison of usage
How to use Fabraix?
To use Fabraix, users can point the Nyx testing harness at their AI agent's endpoint. No complex integration or internal access is needed due to its blackbox nature. The system then runs parallel adversarial simulations to discover failure modes, which are presented in a comprehensive findings report or dashboard.
How to use dassi?
Install the dassi extension and sign up to receive free credits, available for seven days or until used. Give dassi a task in plain English or walk it through the task once. Choose which sites it can use, set a schedule and approval rules, then save the task as a workflow to run on demand or automatically. Scheduled runs need your browser to be open; dassi pauses and asks when it needs your approval.
