Autessa Evaluations and Braintrust
Autessa Evaluations as a Braintrust alternative
Braintrust is a polished eval platform: experiments, scorers in code or LLMs, human review, and Loop, an AI agent that writes prompts, scorers and datasets. It also has one of the fuller MCP servers in the category. Autessa Evaluations goes after two things Braintrust leaves to you: simulated customers that hold real conversations before launch, and response checks that stop a bad reply before it is sent.

Where Autessa wins
Why teams pick Autessa over Braintrust
- Simulated customers push back, ask for a human and check every number, and every case runs as a real multi-turn conversation before you ship.
- Response checks stop a made-up price or a card number before the customer sees it, in chat, SMS, voice and the API.
- Scoring works on day one: groundedness, task completeness, argument faithfulness and efficiency, each with a written justification, and no scorers to write first.
- Braintrust’s MCP is strong, and so is Autessa’s: Claude or your own agent can run a test set, grade transcripts and read results through one connection.
- Change the eval app itself. Ask Autobot for a new review screen or a report for your quality team, down to the code.

FAQ
Questions about switching from Braintrust
Is Autessa Evaluations a Braintrust alternative?
For teams evaluating AI agents, yes. Autessa covers offline test sets, LLM-as-a-judge scoring, online evaluation, human labeling and full conversation logs, and adds simulated users and response checks before send.
Can I grade agents that don’t run on Autessa?
Yes. Send transcripts to the Grading API or upload them in Transcript Grading; no Autessa agent is required.
Does Autessa have custom scorers?
You shape scoring with evaluation notes (a rubric), expected outcomes in plain English, and response checks written as patterns, AutessaScript or AI review criteria.
How far can I customize it beyond scoring?
All the way. The app can be changed down to its code, by Autobot from a plain-language request or by your developers, such as adding a screen or a report of your own.
Can Claude run evaluations through MCP?
Yes. Through the Autessa MCP, Claude, ChatGPT, Cursor or your own agents can run test sets, grade transcripts and read statistics, within the access of whoever connected it.
