What is Zapolnil
Zapolnil is a Russian platform that analyses the top 10 search results for your keyword, writes an article from that data and publishes it to WordPress via the REST API. Notable features: style training on your own texts, cover image generation and a separate mode for news digests from RSS feeds. Pay-as-you-go, no subscription. One significant limit: WordPress only — the site says Bitrix auto-publishing is «coming soon», and for Tilda and other CMSs it suggests copying the finished HTML by hand.
Zapolnil pros
- Top-10 analysis: structure, length, n-grams, LSI, competitor titles and descriptions
- Writing style adapts to samples of your own texts

Zapolnil cons
- Auto-publishing to WordPress only — the site lists Bitrix as «coming soon»
- For Tilda and other CMSs it suggests copying HTML manually
- Social channels limited to Telegram and MAX — no VK or Odnoklassniki

- Longreads with research and source citation are not advertised
