**AI code review in Slack** keeps the review on the pull request and uses Slack only to tap the person who needs to act. In Revix, that tap is a direct message on the Pro plan, sent after a review runs against repo-mined rules. It is not a channel dump of every comment.

This page covers Revix Slack integration and code review notifications in Slack: what ships today, how to evaluate vendors, pricing, and when to skip Slack.

## What AI code review in Slack is

Diff comments, discussion, and merge decisions stay on GitHub.com, GitLab.com, or Bitbucket Cloud. Slack shortens the time until an author or reviewer opens the PR that needs them.

Teams want this because AI coding tools raised how much code lands, while review attention stayed flat. Comments often sit unread in the host inbox. Slack already holds much of engineering attention, so a review signal there reaches a human faster.

Slack does not replace human review, and it does not fix a noisy bot. Faster delivery of equal-weight nits just trains people to mute earlier.

## How Revix Slack integration works

Revix is an AI code reviewer that mines your repository, builds review rules from how the team already writes, and reviews every PR against them. You can edit the rules. Comments carry Conventional Comments labels (issue, suggestion, nitpick, question, praise), so triage is not a flat wall of nits.

Slack is the third layer, after review quality:

1. **The pull request is the source of truth.** Authors, reviewers, and CI meet there, and merge decisions stay there.
2. **Revix reviews against repo-mined rules.** Labeled comments land on the diff.
3. **Slack DMs the person who needs to act.** The message is short: counts, status, and a button to open the PR. Detail stays on the PR on purpose.

Revix matches each Slack user by email in the connected workspace and sends a direct message. It never broadcasts the full comment thread to a channel. Workspaces can turn some notification types off. If Slack delivery fails, the review pipeline still runs.

Git hosts today: GitHub.com, GitLab.com, and Bitbucket Cloud. For the category, see [what is AI code review](https://www.revix.ai/blog/what-is-ai-code-review). For how tools differ on noise and fit, see [Greptile alternatives](https://www.revix.ai/blog/greptile-alternatives).

### Slack DMs Revix sends

| Who      | When             | What you see                                              |
| -------- | ---------------- | --------------------------------------------------------- |
| Author   | Issues found     | Counts for issues, suggestions, nitpicks + link to the PR |
| Author   | Merge conflicts  | Review on hold until the conflicting diff is fixed        |
| Reviewer | Clean first pass | PR is ready for a human review                            |
| Reviewer | Digest           | PRs waiting on you (with new vs already seen)             |

## AI code review comments belong on the PR, not in Slack channels

Keep review comments out of Slack channels in most cases. Channel dumps recreate the backlog you wanted to escape. Everyone sees the noise, and nobody owns the next action. The durable thread still has to live on the PR for merge and audit.

Use each surface for its best job:

| Surface       | Best job                                             | Weak job                           |
| ------------- | ---------------------------------------------------- | ---------------------------------- |
| Pull request  | Diff review, discussion, merge decision              | Catching people who live in chat   |
| Slack DM      | “This PR needs you” to the right person              | Full comment thread or audit trail |
| Slack channel | Team awareness only if you explicitly want broadcast | Primary review inbox               |
| Email         | Async digest, compliance trails                      | Real-time engineering attention    |

Keep the PR first, a Slack DM for the tap, and email as backup. If Slack becomes a second comment inbox, mute returns.

## How to evaluate AI code review Slack integrations

Score vendors on what the product actually does, not on feature checkboxes.

| Criterion               | Good signal                                                | Weak signal                      |
| ----------------------- | ---------------------------------------------------------- | -------------------------------- |
| Comment source of truth | Diff comments stay on the PR                               | Full review thread only in Slack |
| Targeting               | Author/reviewer DMs (or clear ownership)                   | Unowned channel spam             |
| Message job             | Short status + deep link to PR                             | Walls of findings in chat        |
| Quality gate            | Labeled comments or useful-comment focus before notify     | Notify on every nit              |
| Controls                | Per-type notification toggles                              | All-or-nothing noise             |
| Plan honesty            | Clear which tier includes Slack                            | Buried or unclear gating         |
| Host coverage           | Matches your SCM (GitHub.com, GitLab.com, Bitbucket Cloud) | Hosts your team does not use     |

### When to connect Slack, and when to wait

Connect Slack after the comments are worth interrupting for.

**Connect when:**

- Findings regularly wait because nobody opened the host.
- Authors and reviewers already answer faster in Slack.
- Your team already mutes email and host notifications.

**Wait when:**

- Reviewers already open every PR quickly from the host.
- The useful-comment rate is still low, so Slack would only amplify noise.
- You are not on the Slack plan yet, and the trial has not proven review quality.

## Revix Slack is on the Pro plan

As of September 2026, public pricing lists Slack on Pro, next to Jira:

| Plan        | Price (annual)      | Slack                     |
| ----------- | ------------------- | ------------------------- |
| Open Source | Free (public repos) | Not listed                |
| Starter     | €20 per seat        | Not listed                |
| Pro         | €40 per seat        | Listed (with Jira)        |
| Enterprise  | Custom              | Includes Pro capabilities |

Pro also lists higher review volume, faster PR reviews, expert rule supervision, and priority support. Every plan includes a 14-day trial with no credit card. Confirm live numbers on the [pricing page](https://www.revix.ai/pricing).

On Pro, Jira adds ticket context during review. See [introducing Jira context](https://www.revix.ai/blog/introducing-jira-context).

## Setting up Revix Slack

This is the high-level flow. The exact OAuth clicks live in the product.

1. Start a trial on [revix.ai](https://www.revix.ai).
2. Connect GitHub.com, GitLab.com, or Bitbucket Cloud, and enable the repos you want reviewed.
3. Confirm review quality on the PR first.
4. On Pro, connect Slack so DMs reach matched users. Use the same email on Slack and your git host.

The public docs do not show channel mapping, mention filters, or setup screenshots, so this page does not describe them.

## Next step

If review findings already wait on attention, run the review loop on a real repo first. Then decide whether Slack belongs in the path. Start at [revix.ai](https://www.revix.ai). Pro and Slack are on the [pricing page](https://www.revix.ai/pricing).

## Frequently asked questions

### What is AI code review in Slack?

It is a nudge layer, not a second review surface. The pull request stays where comments and merge decisions live. Slack is where the author or reviewer gets a DM when something needs them, so findings do not wait on another browser tab.

### Does Revix have a Slack integration?

Yes. Slack is on the Pro plan, next to Jira. Open source is free for public repos. Starter is €20 per seat annually. Pro is €40 per seat annually. Every plan includes a 14-day trial with no credit card. Confirm on the pricing page.

### Does Revix post AI code review comments into Slack channels?

No. Review comments stay on the pull request. Slack delivery today is a direct message to the matched user (email lookup), with a button back to the PR. The DM says this PR needs you. It does not paste the full comment thread into a channel.

### What Slack messages does Revix send?

Authors can get a DM when Revix found issues, and when merge conflicts put the review on hold. Reviewers can get a DM when a PR is ready for a human pass, plus a digest of PRs waiting on them. Workspaces can turn some notification types off.

### How do I connect Revix to Slack?

Connect GitHub.com, GitLab.com, or Bitbucket Cloud, enable the repos you want reviewed, confirm review quality on the PR, then connect Slack from a Pro workspace. Use the same email on Slack and your git host so we can find you. Exact OAuth clicks live in the product UI.

### Do I need Slack if I already get email and PR notifications?

Only if those already lose to mute. If people open every PR promptly from the host, Slack is optional. If findings sit until someone remembers to check GitHub.com, GitLab.com, or Bitbucket Cloud, Slack is worth evaluating because that is where many engineers already reply.

### Is Slack enough without strong AI code review quality?

No. Faster delivery of flat, equal-weight nits just moves mute earlier. Useful review comes first: repo-mined rules, Conventional Comments labels, then Slack as the tap. Notifications cannot rescue a noisy reviewer.

### Which git hosts does Revix Slack work with?

Revix reviews GitHub.com, GitLab.com, and Bitbucket Cloud pull requests today. Slack is a Pro notification path for those reviews.

### How should I evaluate an AI code review Slack integration?

Check four things: comments stay on the PR, delivery targets the right person (not a noisy channel), notification types match author vs reviewer jobs, and you can turn noisy types off. Then confirm plan gating and email match for user lookup.
