AI release notes generator for GitHub: options compared

An AI release notes generator for GitHub reads your merged pull requests or commits and writes release notes in plain language, instead of listing PR titles. The main options are Engammo, a GitHub App that writes a note for every merged PR and publishes it to a changelog page, widget, RSS feed, and JSON; other hosted tools such as ReleasePad and release-notes.dev; and do-it-yourself setups that combine GitHub's auto-generated release notes, GitHub Copilot, or an AI step in GitHub Actions.

GitHub itself can list what changed, but it does not rewrite it. The value of AI is translation: turning "refactor webhook handler to async queue with retries" into something a customer or a support agent understands. This guide explains the approaches, what to check before you connect a tool to your repositories, and where each one fits.

Three ways to get AI release notes from GitHub

1. Start from GitHub and add AI by hand

GitHub's auto-generated release notes give you a list of the PRs merged since the last release, grouped by label if you add a .github/release.yml. GitHub Copilot can summarize the changes in a pull request, and you can ask an assistant to rewrite a list of changes for customers. This costs nothing extra if you already pay for Copilot, but it is a manual step for every release, and the quality depends on who does it and how much time they have.

2. Build an AI step into your CI

You can add a job to GitHub Actions that collects merged PRs since the last tag, sends them to a language model, and writes the result to a release or a file. GitHub has also introduced agentic workflows, where an AI coding agent runs inside Actions from instructions you write. This gives you full control over the prompt and the model. The tradeoff is that you own the prompt, the API key, the cost, the error handling, and the place the notes end up.

3. Use a dedicated AI release notes tool

Dedicated tools connect to GitHub, generate notes automatically, and host the result. ReleasePad describes itself as a release notes and changelog tool with a GitHub App that drafts notes from repository activity with AI. release-notes.dev describes itself as an AI-assisted tool that turns a repository's commits, pull requests, and tags into grouped release notes. Engammo is described in detail below.

How Engammo generates release notes

Engammo runs on every merge, not on every release, so the changelog is never behind:

1. GitHub sends Engammo a webhook when a pull request merges.
2. Engammo reads the PR title, description, labels, authors, and a trimmed summary of the changed files. If your PR template has sections such as "What was done," "Why," "User impact," or "Technical details," they are recognized and passed to the model separately.
3. The model writes a title of up to 80 characters, a one-sentence description, and 3 to 5 bullets for non-technical readers, plus a longer summary. The prompt tells it not to invent features or links and, when the PR description is thin, to rely on the diff summary instead of guessing.
4. The note is tagged from your labels (features, fixes, breaking changes, security, docs, infra, and more) and published to your changelog page, widget, RSS feed, and public JSON endpoints.

You can edit, regenerate, or hide any note, compile all the changes between two Git tags into one versioned note, and on Pro translate notes into Italian and Spanish. Engammo does not store your source code: it stores the generated note and PR metadata, and when AI summaries are on, a trimmed diff summary is sent to the AI provider for processing.

What to check before choosing an AI release notes generator

• What it reads: PR titles only, PR descriptions, commits, or code changes. More context usually means better notes, but also more data shared.
• Data handling: whether source code is stored, and what is sent to the AI provider.
• Guardrails: how the tool avoids inventing features, and whether you can edit or hide a note before customers see it.
• When it runs: per merge (always current) or per release (batched).
• Where notes go: GitHub Releases only, or a public changelog, in-app widget, RSS, and API.
• Where your code lives: Engammo supports repositories on GitHub.com, including GitHub Enterprise Cloud, but not GitHub Enterprise Server or other Git hosts.

Which one should you use?

• Occasional releases for developers: GitHub auto-generated notes, optionally polished with Copilot.
• You want total control and have time to maintain it: an AI step in GitHub Actions.
• You want plain-language notes after every merge, published for customers and teammates: Engammo.

Engammo's Free plan covers 1 repository, 15 release notes per month, and 10 AI summaries per month, with no credit card; Pro is $19/month for up to 5 repositories and unlimited notes and AI summaries.
