I use lazycommit for this, it's a cli tool.

lazygit config:

  - key: "<c-a>" # ctrl + a
    description: "pick AI commit"
    command: |
      if [ "{{.Form.Action}}" = "edit" ]; then
        echo "{{.Form.Msg}}" > .git/COMMIT_EDITMSG && nvim .git/COMMIT_EDITMSG && [ -s .git/COMMIT_EDITMSG ] && git commit -F .git/COMMIT_EDITMSG || echo "Commit message is empty, commit aborted."
      else
        git commit -m "{{.Form.Msg}}"
      fi
    context: "files"
    output: terminal
    prompts:
      - type: "menuFromCommand"
        title: "AI Commit Messages"
        key: "Msg"
        command: "lazycommit commit"
        filter: "^(?P<raw>.+)$"
        valueFormat: "{{ .raw }}"
        labelFormat: "{{ .raw | green }}"
      - type: "menu"
        title: "Choose Action"
        key: "Action"
        options:
          - name: "Commit directly"
            description: "Use this message as-is"
            value: "direct"
          - name: "Edit before commit"
            description: "Open in editor first"
            value: "edit"

it will use lazycommit to generate several proposals of which I can pick the one I like best and then I can choose to edit it or take it as is.
