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

  • Writing style adapts to samples of your own texts
  • News digests from RSS feeds with scheduled publishing
  • Pay-as-you-go: you pay for actual articles, not for a month

Zapolnil cons

  • Auto-publishing to WordPress only — the site lists Bitrix as «coming soon»
  • For Tilda and other CMSs it suggests copying HTML manually

Frequently asked questions

How does SEO Writer differ from Zapolnil?+
Both services share the same core: take a keyword, analyse the SERP, write an article and publish it. The difference is coverage. Zapolnil publishes to WordPress; SEO Writer also covers 1C-Bitrix, InSales, Joomla and any site via webhook. After publishing, SEO Writer sends announcements to Telegram, VK, Odnoklassniki and Pinterest, produces 8,000+ word longreads with research, and gives agencies a workspace with clients and approvals.
Which is cheaper — Zapolnil or SEO Writer?+
At small volumes Zapolnil is cheaper: ₽15–40 per article versus ₽59.8 on the Pro plan. But compare what the price covers. With SEO Writer it includes image selection and upload, cover generation, video embedding from RuTube and VK Video, internal linking and announcements to four social networks — which cost more separately than the difference in plan price.
Does Zapolnil publish to Bitrix?+
As checked on 10 September 2026, the Zapolnil site lists Bitrix auto-publishing as «coming soon» and describes the current method as copying the finished HTML and pasting it into the site. SEO Writer publishes to Bitrix automatically through a connector installed in the site root.
Can I run several client sites?+
SEO Writer has an agency workspace for this: clients join by invitation, each has their own article quota, materials go through approval, and you can log into a client account to review. The Agency plan covers up to 20 sites. Zapolnil does not advertise such a mode on its site.
