Start with one useful result.

Define what good looks like, see what changed, or find the next failure to investigate. Try a fictional example or use your own inputs. Download the result before you leave.

Your inputs stay in this browser. Workspace access is a separate, optional step.

01

Dataset starter

What should your agent get right?

Turn a task and a reference answer into an editable evaluation contract and first case.

You leave with: Contract + reference case

Build my starter →
02

Output comparison

Did your change help?

Compare supplied baseline and candidate outputs. Find regressions, improvements and missing results.

You leave with: Case-by-case report

Compare outputs →
03

Quality report reader

What should you investigate next?

Read a ProofSeal or TestLore JSON report and get a focused next step.

You leave with: Findings + next step

Read a report →

Open-source developer tool

Move a working feature. Check what came with it.

Code Transplant extracts a TypeScript parser’s dependency boundary, adapts its interface to another application, and compares behavior against the original. Inspect the first demonstration, then run the local CLI in your own repository.

The website displays the proof; source extraction and execution happen locally.

Your tools. A connected review flow.

ProofSeal and TestLore run independently in your own repository. Gradia Guard records covered execution and verifies its evidence. A Gradia workspace can connect their reports to approved evaluation criteria and independent human review.

Passing software tests and intact recordings answer specific questions. Your team still approves the requirements, case answers and business acceptance criteria.

Ready for your team’s real workflow?

Start with the task you just explored. Agree on success, review the contract, generate case proposals, and inspect recorded failures before choosing the next experiment.

Access is by invitation. The free tools and downloads stay available without joining.
