Maruhide Postkeeper – AI Auto-Post & Recovery

Maruhide Postkeeper generates Japanese blog articles with AI and takes care of what happens after generation: drafts for human review, retrying when the AI API call fails, and publishing scheduled posts that missed their publish time. Use your own Anthropic (Claude) or OpenAI key (BYOK), or — on WordPress 7.0 and later — the AI provider you connected in Settings → Connectors.

Every feature is free to use. There is no license key, no locked feature, and no usage limit inside the plugin.

Articles are written in Japanese. The built-in prompt produces Japanese articles (about 2,000+ characters, H2/H3 structure). Other languages are not supported yet.

Key features

• AI article generation — Anthropic (Claude) or OpenAI with your own key, or the WordPress AI Client (WordPress 7.0+).
• Drafts for review by default — articles are saved as drafts and labelled as AI-generated, so a person checks them before they go live.
• Daily generation — one article at your chosen time, via WP-Cron.
• Automatic retry — a temporary API error is retried up to 3 times (after 60 and 120 seconds). Errors that a retry cannot fix (wrong key, unknown model name) are logged instead.
• No cut-off articles — if the AI stops at its output limit, the incomplete article is not saved and the reason is logged.
• Missed-publish recovery — every hour, scheduled posts still marked “Scheduled” after their publish time are published. You can limit this to posts created by this plugin.
• Eyecatch (featured image) — a title card is generated with GD. A Japanese font (BIZ UDGothic) is bundled, so Japanese titles render as-is.
• Measurement — success rate, retries and recovered posts are recorded and can be exported as CSV.

日本語

AIで日本語の記事を生成し、生成した後の運用――下書きでのレビュー、API失敗時の自動リトライ、予約投稿の公開漏れの自動公開――までを面倒みるプラグインです。すべての機能を無料で、制限なくご利用いただけます。

• 既定は下書き保存：AI生成の開示ラベルを付けて下書きに保存し、人が確認してから公開します。
• BYOK（Bring Your Own Key）：ご自身の Anthropic (Claude) / OpenAI のAPIキーを使用。WordPress 7.0 以降なら「設定 > コネクタ」のAIプロバイダも使えます。キーはご自身のサイト内にのみ保存され、開発元は受け取りません。
• 自動リトライ：一時的なAPIエラーは最大3回まで再試行。キー違い・モデル名違いなど再試行で直らない失敗はログに理由を残します。
• 途中で切れた記事を保存しない：AIが出力上限で止まった場合は保存せず、理由をログに残します。
• 公開漏れの自動公開：1時間ごとに、予約時刻を過ぎても「予約済み」のまま残った投稿を公開します（対象を本プラグイン作成分に限定することもできます）。
• アイキャッチ自動生成：日本語フォント（BIZ UDゴシック）同梱。
