The decision
Should Evidently AI make your shortlist?
Start with the job, the team, and the constraints. Product fit becomes much clearer when those three line up.
Practical use cases
Jobs it can take on
- Evaluate LLM outputs for quality, safety, and reliability
- Generate adversarial test inputs for AI applications
- Monitor data drift and model performance over time
Before you choose
Know the tradeoffs
- A self-hosted Enterprise trial requires contacting Evidently.
- Using third-party LLM APIs for evaluations can require sharing data externally.
Inside the product
What you can actually do with it.
The core product capabilities, grouped around the work they enable.
Built-in and custom evaluations
Evidently provides more than 100 built-in metrics and supports custom rule-based, classifier-based, and LLM-based evaluations.
Synthetic and adversarial testing
Teams can create realistic, edge-case, and adversarial inputs tailored to an AI use case.
Continuous monitoring
Evidently tracks evaluation results and ongoing quality checks in dashboards to surface drift, regressions, and emerging risks.
Typical workflow
Create an evaluation workflow using the Evidently Python library or Cloud, then provide traces or raw data and select metrics or tests. Run the evaluations locally or in the platform and review reports or dashboards to investigate quality changes.
