See how they actually
build.
Lentara turns your codebase into a real, AI-allowed work-trial. In 30 to 90 minutes, watch a candidate solve a real problem, with and without AI, then hire on evidence instead of a resume.

What Lentara is
A real work-trial, generated from your own code.
Point Lentara at your repository, your tickets, and the role you are hiring for. It writes a scoped assessment that mirrors the work the job actually involves, plus the grader to score it. No more generic puzzles, no more hand-graded take-homes.
And when your pipeline runs thin, Lentara brings its own bench: a vetted base of top AI engineers, researchers, and Forward Deployed Engineers, the archetype that can sit with a customer, scope the problem, and ship. All of them ready to take your work-trial.

Connect. Generate. Review.
Zero engineering hours to run your top of funnel. Lentara builds the assessment; you read the results.
Connect
Link your repository, tickets, and job description. Share as much or as little as you like; none of it is required to start.
Generate
Lentara writes a scoped work-trial and its grader, then runs an AI agent baseline so you know exactly where the bar sits.
Review
Candidates build in their own environment. You get a graded, evidence-cited report and a shortlist worth your time.
Why teams switch
Hire the way you always wanted to.
Get your engineers out of the funnel
No more writing interview problems, running screening calls, or grading take-homes. The first time your team meets a candidate, they already know they can build.
Plug into the process you run
Candidates sync to and from Ashby, Greenhouse, and Lever automatically, or you can run everything end to end on Lentara. Your pipeline stays exactly as it is.
Work-trial depth, every time
See how someone builds over a real task, how they use AI, and how they explain their decisions. Signal no screening call or whiteboard can show you.
The candidate experience
The assessment candidates want to take.
A real feature in a real codebase beats a contrived puzzle. Candidates work the way they actually work, and the good ones enjoy it.
Their own editor and AI tools
VS Code, Cursor, and whatever assistants they use on the job. We encourage it.
Every step, on the record
File iteration, commit history, and AI prompts are tracked across the whole build.
A short spoken walkthrough
Candidates record a few minutes explaining what they built and why.
Graded on real correctness
Every submission runs in a live sandbox against a deterministic test harness.
Why now
Anyone can prompt an AI now. The only thing that separates engineers is what they build when the task is real, and how they reason while they build it. That is exactly what a work-trial shows, and a resume never will.
— The Lentara thesis
Stop guessing. Watch them build.
Bring your codebase. We will build your first work-trial from it, and you can send it to a candidate within days.
