HyperWrite
Tool · this deep dive is built from the official pages of the platform itself and of the tools that support it.
Overview
HyperWrite is an AI writing assistant. By the pricing page it includes hundreds of ready tools and templates for creating and editing text, a document editor, TypeAhead suggestions right as you type through a browser extension, customisable "personas" tuned to an author's style and real-time research with citations and links to sources.
Input languages are named nowhere: neither the pricing page nor the terms list them. The only close phrase in the FAQ — "HyperWrite can research and write about almost any topic" — is about topics, not languages. So on Russian, Arabic, Hindi and Chinese the tool has no answer: the documents have been read, the question is not examined in them.
Which platforms it works with
Publishing for you the tool does not undertake. Two entry points are declared: a Chrome extension and a web document editor at app.hyperwriteai.com — both named in the product menu and in the footer of the pricing page.
Direct export to social networks, to content management systems or to mail is not declared in what was read. The extension works on top of the browser — TypeAhead suggestions appear as you type — but that is work in someone else's window, not sending text to a platform.
Pricing
Two paid steps, both with a monthly and an annual price; the sums are from the pricing page, where both columns — Monthly and Annual — are present at once.
Premium — 19.99 USD a month monthly and 16 USD a month with annual payment, an invoice of 192 USD a year. Ultra — 44.99 USD a month monthly and 29 USD with annual payment, an invoice of 348 USD a year.
The lowest step of entry is 16 USD a month, but only when paying for a year at once. Monthly the cheapest is 19.99 USD.
What is free
Free access exists, but without numbers. A separate card for a free plan is not on the pricing page; the only mention is in the FAQ, verbatim: "With a Free account, you will have limited monthly credits on our basic AI".
From this three things are known: a free account exists, its credits are monthly and limited, the model is basic. How many credits exactly — the page does not report. The document has been read, the number is not in it.
Restrictions
The unit of counting on the paid plans is AI Messages, and it is monthly.
Premium — 250 AI Messages a month, 3 custom personas and unlimited TypeAhead suggestions. Ultra — unlimited AI Messages and 10 personas.
The free account is described differently and without figures: "limited monthly credits" on the basic model. The limits of Premium and Ultra are confirmed by the cards of the pricing page; the limit of the free one is confirmed by nothing except the word "limited".
Rights to the output
A direct answer the document does not give, and this has to be said honestly. The terms do not allocate rights to the generated text: a separate clause about Output is not in them.
What is in them is a licence to use the platform, granted verbatim "for your personal, non-commercial purposes". It relates to the service, not to the output, but commercial use is not permitted by this document on any step: by plan the terms do not divide rights, the reservation is one for all.
The upshot: whose the text is at the output the terms do not say; whether the tool may be applied in commercial work they do say, and the answer is negative.
Do they train on your data
They do, and the tool admits it directly. The terms allow data to be used "to improve the Software, including to train its machine learning algorithms applicable to its general user base and systems, and related products". The wording is repeated twice — for data from the device and for data about usage; separately named are the content of letters and the nature of interaction with the service.
An opt-out is described, and described with an address. Verbatim: "you shall have the right to opt-out of the general systems". After the opt-out the data are used only for models trained for the specific user, and the request is sent by mail to info@othersideai.com.
There too is a warning about the price of the opt-out: whoever opts out does not receive the benefit of models trained on the general systems. The opt-out works, but it also changes what the opting-out user gets.
How you earn with it
Commercial use is not opened by the read edition of the terms: the licence to the platform is granted "for your personal, non-commercial purposes", and by plan this reservation is not divided — it is the same for Premium, Ultra and the free account.
The reservation is worth reading literally: it is about the licence to the service itself. A separate clause that would pass rights to the created text to the user is not in the document. So the question rests on a restriction on using the service, not on rights to the text.
What it will not do
Publish text for you it will not: direct export to social networks and to content management systems is not declared in what was read.
Let through material infringing someone else's rights it should not. The terms forbid uploading material infringing third-party intellectual property rights, privacy and confidentiality obligations, and also content "vulgar, offensive, inappropriate, harassing, defamatory, abusive, lewd, pornographic, obscene or otherwise objectionable".
Write stretched comparative advertising it will not allow: false and misleading comparative statements are forbidden directly. Spam and mass mailings are forbidden by a separate clause.
Work from countries under US embargo it will not permit: such a ban is in the terms.
Mark what is written as machine-made it will not offer: neither watermarks, nor metadata, nor C2PA, nor a requirement to label the output is in what was read. The closest to the subject is a recommendation from the FAQ of the pricing page: "always check your work and make it your own before publishing". That is advice, not a rule.
Name the languages it works in it does not undertake either.

yes, verbatim: «you shall have the right to opt-out of the general systems»; after opting out the data is used only for models trained for that particular user; the request is sent by email to info@othersideai.com, and there is a warning in the same place that after opting out the user does not benefit from models trained on the general systems

the terms do not allocate rights in the generated text directly; the licence to use the platform is granted «for your personal, non-commercial purposes» — verbatim, so commercial use is not permitted by this document. There is no difference between plans in the text of the terms
the wording is from section 2, Ownership Rights and License; there is no separate clause about Output in the document, so the conclusion about commercial use rests on the licence to the service, not on a clause about the result
