// AI code review agent

Your PRs deserve
a real review.

Pullflow is an AI agent that reviews every pull request, catches logic bugs you missed, writes the tests that should exist, monitors your CI, and only pings you when something actually needs attention.

pullflow review — PR #847

// src/billing/stripe.js — changed in this PR

async function chargeCustomer(customerId, amount) {
  const customer = await getCustomer(customerId);
  const charge = await stripe.charges.create({
    amount,
    currency: customer.currency,
    customer: customer.stripeId,
    description: `Charge for ${customerId}`
  });
  return charge;
}

pullflow ⚠ Currency mismatch — customer.currency may not match stripe's supported currencies. Consider validating or falling back to 'usd'.

pullflow ✓ No test exists for this function. Writing one now.

Not a bot. An employee.

Bots run when you push. Agents run all the time. Pullflow monitors, thinks, and acts — the way a senior engineer would, if they didn't have 40 other things on their plate.

Logic-level review

Not just style and linting. Pullflow reads your code's intent, catches edge cases, flags potential bugs, and asks hard questions about the logic.

Writes the tests you missed

Detects untested functions and generates meaningful test cases — not just coverage padding. Real tests that would have caught bugs in production.

CI/CD monitoring, always on

Tracks flaky tests, CI failures, and regression patterns across your pipeline — not just on the PR you're looking at right now.

Smart alerting

Slack when it's urgent. Email digest when it's not. Pullflow learns what matters to your team and only interrupts when it has to.

GitHub-native, zero friction

Install as a GitHub App. No config files, no YAML pipelines, no custom workflows to maintain. One click and it watches your repos.

Context-aware

Pullflow reads your codebase — not just the diff. It understands how functions fit together, so reviews actually make sense, not just syntax-check.

How it works

Install

One-click GitHub App install. Pick your repos. Pullflow starts watching immediately — no config files, no CLI setup.

Review

Every PR gets a full review. Pullflow reads the diff in context of your codebase, flags logic issues, and writes comments directly in the PR.

Test

Missing test coverage gets flagged and filled. Pullflow generates tests that actually cover the edge cases — not just to hit a coverage percentage.

Monitor

CI runs are tracked. Flaky tests are logged and reported. Patterns are surfaced before they become incidents.

Alert

When it matters: Slack ping. When it can wait: daily digest. Your team stays informed without inbox overload.

"GitHub added a review bot. The bot approved your PR. Did it actually catch anything? Probably not."

Code review is the highest-leverage thing a senior engineer does. It's also the easiest thing to half-do when you're overwhelmed. Every team we've talked to has the same problem: PRs sit unreviewed for days, and when they do get reviewed, it's a rubber stamp.

AI coding assistants (Copilot, Cursor, Claude) have made the problem worse, not better. Developers write more code, faster — which means more PRs, more review burden, and more shortcuts taken.

We built Pullflow to close this loop. A senior engineer who never sleeps, never gets tired, and never rubber-stamps anything.

Your PRs deservea real review.
