Conventional commits have become the standard for writing meaningful Git commit messages. The format (feat:, fix:, docs:, chore:, etc.) provides structure that tools can parse to automatically generate changelogs, version bumps, and release notes. However, manually crafting these commit messages and then aggregating them into a readable changelog remains time-consuming. This is where AI coding tools step in to automate the entire workflow.
The Conventional Commit Workflow
Before looking at AI tools, let’s establish the conventional commit foundation. The specification uses this format:
<type>(<scope>): <subject>
<body>
<footer>
Common types include:
feat: New featuresfix: Bug fixesdocs: Documentation changesstyle: Code style changesrefactor: Code refactoringtest: Adding or updating testschore: Maintenance tasks
Tools like commitlint validate commit messages, while standard-version or release-please use these messages to generate changelogs. The problem is that developers still need to write descriptive, conventional commit messages manually.
AI-Powered Solutions for Commit Message Generation
1. GitHub Copilot
GitHub Copilot now includes intelligent commit message generation. When you stage changes and run git commit, Copilot analyzes your diff and suggests commit messages that follow conventional commit standards.
Setup:
# Enable Copilot's commit suggestions
gh copilot config --enabled commit-suggestions true
Workflow:
git add .
git commit # Copilot suggests conventional commit messages
Copilot examines your staged changes, understands the context, and generates messages like feat(auth): add OAuth2 login support or fix(api): resolve null pointer exception in user service.
2. Ollama with Commit Analysis
Ollama runs local LLMs that can analyze Git diffs and generate commit messages. This approach keeps your code private while using AI.
Setup:
# Install Ollama
brew install ollama
# Pull a code-savvy model
ollama pull codellama
# Create a commit helper script
Script: git-ai-commit
#!/bin/bash
DIFF=$(git diff --cached)
RESPONSE=$(curl -s http://localhost:11434/api/generate -d "{
model: 'codellama',
prompt: 'Analyze this git diff and write a conventional commit message. Types: feat, fix, docs, style, refactor, test, chore. Include scope if relevant. Diff:\n$DIFF',
stream: false
}")
MESSAGE=$(echo $RESPONSE | jq -r '.response')
echo "$MESSAGE"
Run it with staged changes:
git add .
git-ai-commit # Outputs AI-generated commit message
git commit -m "$(git-ai-commit)"
3. Aider: AI-Powered Git Integration
Aider is a command-line AI coding assistant that integrates directly with Git. It tracks your edits and can automatically generate conventional commits.
Setup:
pip install aider
Configuration:
# Configure Aider with conventional commit rules
aider --commit-policy conventional
Usage:
# Edit your code, then let Aider create the commit
aider your_file.py
# After edits, run:
/commit
Aider analyzes your changes and generates appropriately typed commits. You can also use /git diff to review before committing.
Automating Changelog Generation
Once you have conventional commits, AI tools can aggregate them into polished changelogs.
1. Release-please with AI Enhancement
Release-please by Google automates version management and changelog creation. Combined with AI, it becomes more powerful.
Setup:
npm install -g release-please
Workflow:
release-please --release-type node --bootstrap-version 1.0.0
This creates a release-please-config.json and generates PRs with automated changelogs based on your conventional commits.
2. GitHub Actions with AI Summarization
Create a GitHub Action that uses AI to summarize commits into readable changelog entries:
.github/workflows/changelog.yml
name: AI Changelog Generator
on:
push:
branches: [main]
pull_request:
types: [closed]
jobs:
generate-changelog:
if: github.event.pull_request.merged == true
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
with:
fetch-depth: 0
- name: Generate Changelog
run: |
COMMITS=$(git log --pretty=format:"%s" main..HEAD)
RESPONSE=$(curl -s -X POST http://localhost:11434/api/generate \
-d '{
"model": "codellama",
"prompt": "Summarize these conventional commits into a user-friendly changelog entry:\n'"$COMMITS"'",
"stream": false
}')
CHANGELOG=$(echo $RESPONSE | jq -r '.response')
echo "$CHANGELOG" >> CHANGELOG.md
3. Changesets with AI
Changesets is another popular tool for managing changelogs:
npx @changesets/cli init
npx changeset add # Creates a changeset file
While not AI-native, you can pipe its output through an LLM for human-readable summaries:
npx changeset version 2>&1 | \
curl -s -X POST http://localhost:11434/api/generate \
-d '{"model": "codellama", "prompt": "Format this as a clean changelog:", "stream": false}'
Tool Comparison: AI Commit and Changelog Tools
| Tool | Commit Message Gen | Changelog Output | Privacy | Cost |
|---|---|---|---|---|
| GitHub Copilot | Yes (IDE + CLI) | No (needs release-please) | Cloud | $10-19/mo |
| Aider | Yes (built-in) | No | Cloud/Local | Free + API costs |
| Ollama + codellama | Yes (custom scripts) | Via scripts | Local (private) | Free |
| release-please | No | Yes (GitHub Actions) | Cloud | Free |
| Changesets | No | Yes | Self-hosted | Free |
| git-cliff | No | Yes (rule-based) | Local | Free |
For teams with strict data privacy requirements, the Ollama approach offers commit message generation without sending diffs to external APIs. Codellama 13B handles conventional commit generation accurately for most common change types — new files, modified functions, dependency updates. Larger changes with multiple files benefit from the 34B parameter model if you have the hardware.
For teams comfortable with cloud AI, GitHub Copilot provides the smoothest developer experience because it integrates directly into VS Code and JetBrains IDEs without any scripting. The commit message appears in the commit input field as a suggestion, requiring only Tab to accept.
Integrating git-cliff for Rule-Based Changelog Generation
git-cliff is an underused tool that deserves mention alongside AI-powered options. It parses conventional commits using a configurable template engine and produces formatted changelogs without requiring AI at runtime. This makes it fast, deterministic, and free:
# Install git-cliff
cargo install git-cliff
# or via brew
brew install git-cliff
Configure it with a cliff.toml file:
[changelog]
header = "# Changelog\n"
body = """
{% for group, commits in commits | group_by(attribute="group") %}
## {{ group | upper_first }}\n
{% for commit in commits %}
- {{ commit.message | upper_first }} ([{{ commit.id | truncate(length=7, end="") }}]({{ commit.id }}))
{% endfor %}
{% endfor %}
"""
[git]
conventional_commits = true
filter_unconventional = true
commit_parsers = [
{ message = "^feat", group = "Features" },
{ message = "^fix", group = "Bug Fixes" },
{ message = "^docs", group = "Documentation" },
{ message = "^chore", group = "Maintenance" },
]
Run it against your tag range:
git-cliff v1.0.0..HEAD --output CHANGELOG.md
The practical workflow combines both approaches: use an AI tool (Copilot or Ollama) to write high-quality conventional commits at the point of development, then use git-cliff at release time to aggregate those commits into a formatted changelog. AI handles the creative work of describing what changed; git-cliff handles the mechanical work of organizing it.
Best Practices for AI-Assisted Changelog Workflow
Validate commit messages. Use commitlint to ensure AI-generated commits follow your conventions:
npx commitlint --from HEAD~1 --to HEAD --format conventional
Review before committing. AI makes mistakes. Always review suggested commit messages and adjust if needed.
Provide context. When using AI for commit messages, include issue numbers or PR context in your prompts for more accurate suggestions.
Use scopes consistently. The scope field in conventional commits (feat(auth): ...) dramatically improves changelog readability. Establish a list of valid scopes for your project and include them in your AI prompts.
Automate the release PR. release-please creates a release PR automatically when merged commits accumulate enough changelog-worthy changes. Pair this with AI-generated commit messages to create a fully automated release documentation pipeline that requires human approval but no manual writing.
Train your model. If using local models like Ollama, provide feedback on commit suggestions to improve accuracy over time.
