These Terms of Service (“Terms”) govern your use of Blost (blost.ai), a service operated by Corpus Communications Kft., registered at 1025 Budapest, Csalán út 26., Hungary (“Company”, “we”, “us”). By creating an account or using Blost, you agree to these Terms.
Blost generates SEO-oriented blog articles using AI and, if you connect your WordPress or UNAS site, can publish them there on your behalf on a schedule you configure. You may also connect Google Search Console to view performance statistics for published articles inside Blost.
Blost offers a 3-day free trial; no payment is collected during the trial period. After the trial ends, continued use requires a paid subscription plan -- see blost.ai/#pricing for current plans and pricing. Billing is processed via Stripe on a recurring basis until you cancel, and you can cancel anytime from your account settings. We'll notify you before your trial ends so you can choose a plan or cancel.
Blost is offered primarily to businesses (sole traders and companies) for business use. If you are an individual consumer under applicable law -- acting outside your trade, business, craft, or profession -- the additional consumer rights described in Section 4 below apply to you. When creating an account, you accept these Terms via a checkbox, and, if you are subscribing as a private individual (consumer), you also confirm that you request immediate performance of the service as described in Section 4.
If you are using Blost as a consumer under Section 3 above, EU and Hungarian consumer-protection law (Directive 2011/83/EU and Hungarian Government Decree 45/2014 (II. 26.)) gives you the right to withdraw from the contract within 14 days of concluding it, without giving any reason.
Because Blost is a digital service made available immediately from the start of the trial, when creating your account you expressly consent -- via a dedicated checkbox -- to the Company beginning performance of the service immediately, before the 14-day withdrawal period expires, and you acknowledge that by giving this consent you lose your right of withdrawal once performance of the service has begun.
If you do not consent to immediate performance, please do not create an account and instead contact us using the details in Section 14 below to exercise your consumer withdrawal right.
You are responsible for keeping your login credentials secure and for all activity under your account. You must provide accurate information when connecting third-party services (e.g. WordPress, UNAS, Google Search Console).
When you connect WordPress or UNAS, you authorize Blost to create and update posts on that site using the credentials (application password or API key) you provide. When you connect Google Search Console, you authorize Blost to read (but not modify) your Search Console performance data, as described in our Privacy Policy. You can disconnect any of these services at any time in Settings.
You own the articles and content generated through your Blost account. You are responsible for reviewing AI-generated content before publishing it, including for factual accuracy and compliance with applicable law.
Article 50 of the EU Artificial Intelligence Act (AI Act) -- in force since August 2, 2026 -- requires that text generated by an AI system, when published to inform the public on matters of public interest, be disclosed as AI-generated, unless it has undergone substantive human editorial review with an identifiable person or organization taking editorial responsibility for it. This obligation legally falls on the publisher of the content -- that is, you, as a Blost customer -- not on Blost as the tool that generated the text.
To help you comply, Blost offers an optional, built-in labeling feature: enabled by default, it appends a short, visible note to the end of published articles stating that they were created with the help of AI. You can turn this feature on or off at any time in Settings → Content. If you carry out substantive editorial review of an article before publishing it and take editorial responsibility for it yourself (or through your organization), you may turn the feature off -- in that case, compliance with the disclosure obligation is solely your responsibility.
You agree not to use Blost to generate or publish unlawful, infringing, or abusive content, or to attempt to interfere with the security or normal operation of the service.
Blost is provided “as is”, without warranties of any kind. AI-generated content may contain errors; you are responsible for reviewing it before publication. To the maximum extent permitted by law, the Company is not liable for indirect, incidental, or consequential damages arising from use of the service.
You may stop using Blost and request account deletion at any time. We may suspend or terminate accounts that violate these Terms.
We may update these Terms from time to time. Continued use of Blost after a change constitutes acceptance of the updated Terms.
These Terms are governed by the laws of Hungary.
