Your standards, reviewing every pull request
Tessl Code Review reads the whole PR against your team's standards, remembers what's already been fixed or declined, and gets more accurate with every review.

Trust the code you didn't write.
Agents generate more code in a minute than a person writes in a day. Signing off is still on you. AI-generated PRs carry 1.7x more issues than human-written ones. Tessl checks every PR against your standard first, so code review doesn’t become your bottleneck.
One loop: write, review, auto-maintain.
Code review isn't a single check at the end. It's a loop that runs continuously against a standard your team controls.
01
Define your standards in a skill
Use Tessl’s pre-defined code review rules, customize or build your own.
02
Review every pull request
Your agent implements against the same standard it's reviewed against, not a generic style guide.
03
Continuously improve your context
Every finding feeds back into the standard for continuous improvement.
Ownership
Your standard. Not a vendor's settings screen.
01
Write it once, as a skill
Plain-language rules your team actually agrees with, not a checkbox form buried in a settings page you don't control.
02
Customize
Change the standard the moment your team's practices change. No support ticket, no vendor release cycle, just edit the skill.
03
Take it with you
Versioned, inspectable, and portable to any repo or agent, including if your team changes tools.
Don’t fix the same problem twice.
Push an update. Tessl already knows what's fixed, what's been explained, and what's been declined. If a fixed issue quietly comes back, Tessl catches it. Re-review checks only what's still open. The conversation gets quieter as the PR gets closer to merge.
Fixed — idempotency key added to chargeCard()
Declined — retry logic intentional, confirmed by @mrivera
Still open — refundCard() missing idempotency key

Webinar on-demand
AI agents are shipping code faster than a human review process can handle. Tessl Code Review is built for that reality: multi-agent review that runs on every PR, tuned for signal over noise. Marc and Colin are running it live on a real pull request.

Built to hold up at enterprise scale.
The same standard, applied consistently everywhere your organization builds, with the controls an engineering leader actually needs.
Governance without settings sprawl
Standards your team owns, applied consistently across every repo and every agent your organization runs, with no per-tool settings screens to keep in sync.
Depth that tracks risk, not diff size
A one-line typo fix and a payments migration don't need the same scrutiny. Review depth, and cost, scale with what's actually risky.
Coverage you don't have to remember
97% of merged pull requests were reviewed automatically in our own day-to-day use. No one has to remember to trigger it.
Start on your next pull request.
See it running against your own codebase and your own standards.
One loop. Many more when you're ready.
Code review is one of the loops that runs out of the box on Tessl. The same standards and context extend to how your agents implement, test, and maintain code.
