Corrige.it
Corrige.it is an Italian AI proofreading service that checks spelling in context, scores readability with the Gulpease index and builds lexical hypertexts. It runs online, inside Word 365 or through an API, and never rewrites your text.
What is Corrige.it?
Corrige.it is an Italian spelling and readability engine built by EuloTech srl, a software company based in Matera. Its distinguishing claim is contextual: rather than matching words against a dictionary, it weighs each word and expression against the sentence around it, so the same word can be reported in one passage and left alone in another. The site's own demonstration is the phrase Presidente del Coniglio, a perfectly spelled word in entirely the wrong place, which ordinary checkers wave straight through.
One submission produces three reports. Ortografia gathers the spelling findings, Leggibilita scores readability sentence by sentence using the Gulpease index and the Vocabolario di base, and Ipertesto rebuilds the text as a lexical hypertext with concordances and lists usable for indexing. All three are delivered through HyAcInTHa, short for Hypertext Acknowledgement In Typo Hazard, an interface that groups findings into a single synthetic table so an editor never has to scroll the whole document. Each entry carries the normalised word, its variants, general information, links to external references, and either a proposed correction or the reason for a suspicion.
Underneath sits a knowledge base the company describes in two halves: a probabilistic language model holding hundreds of millions of usage contexts, and a deterministic layer of several hundred thousand precisely known items with statistical and lexicographic notes. An Italian large language model is combined with rule-based routines for proper nouns, punctuation and units of measure. Machine learning is supervised by a staff of linguists and terminologists, and the base is updated every working day.
The tool deliberately stops short of writing. It reports and explains, leaving the decision, and the visto si stampi, to the person responsible. It answers within seconds even on book-length material and accepts a wide range of file formats. It is reachable three ways: through the website, through the CheckTO.it add-in for Word 365, and through the Corrige.WebService API in URL or XML mode. An isolated on-premise build exists for organisations with strict security requirements, and Italian public bodies can buy it through the MEPA marketplace.

When to use Corrige.it / When not to
A quick filter to help you decide if Corrige.it is the right fit.
When to use Corrige.it
- Publishing houses and imprints that need every proof checked, from manuscript to final PDF, without a word cap
- Professional proofreaders and copy editors working on long-form Italian texts
- Translators working into or out of Italian who need a clean source or a polished target
- Technical documentation teams that depend on consistent specialist terminology
- Italian teachers, Italian-as-a-foreign-language tutors and the students they set written work for
When not to use Corrige.it
- Anyone writing in a language other than Italian, since no other language is actually checked
- Writers who want the text corrected for them: Corrige.it flags and explains, it never rewrites
- Occasional users, because the trial stops at 500 words and the cheapest paid entry is EUR 100 excluding VAT
- Mobile-first users, as there is no iOS or Android app and the only add-in targets Word 365
- Procurement teams that require a signed data processing agreement and a published subprocessor list before onboarding a vendor
How to use Corrige.it
A typical end-to-end flow, from setup to results.
- Start with the free trial: submit one document of up to 500 words and an email address to receive the reports
- For regular use, write to the editorial desk to activate a subscription and open a word account
- Choose Controlla un testo on the site and point the system at the file you want checked
- Let the system count the words free of charge, read its time estimate and confirm; cancelling costs nothing
- Wait a few seconds, or a few minutes for book-length texts and for annotated PDFs
- Open the reports from the unique link emailed to you, or from the Resoconti tab of the add-in
- Work through the HyAcInTHa summary rather than the whole document, using the context shown either side of each occurrence
- Press Corretta or Errore to teach the engine your own terminology; the choice applies to every later check
- Download the reports within the ten days they stay online if you need to keep them
- To work inside Word 365, install the CheckTO.it add-in from the Office Store and sign in with the same credentials
Pros & Cons
Pros
- Catches errors ordinary checkers miss because the judgement is contextual, separating perla from per la and fragranza from flagranza
- Explains every finding and links to lexicographic and encyclopedic sources, so the tool teaches while it corrects
- Knowledge base refreshed every working day under human supervision rather than left to drift
- Your own terminology enters the engine with a single click and applies to all later checks
- Handles book-length and encyclopedia-length material in seconds, with a summary that spares a full read-through
- No fixed fees, no renewal obligation, and a full refund within fourteen days under Italian consumer law
- Broad file-format support with nothing to install online, plus an isolated on-premise build for high-security environments
Cons
- Italian only: no other language is actually checked, however many foreign words the knowledge base recognises
- No permanent free tier, with the trial capped at 500 words and the cheapest paid entry at EUR 100 excluding VAT
- Buying is not self-service; activating a subscription means emailing the editorial desk
- Unused words are wiped when the twelve months expire and are not refundable after the withdrawal window
- Re-checking the same text debits the word account a second time
- No mobile app, the only add-in is for Word 365, and the InDesign add-in remains announced rather than shipped
- No data processing agreement, no subprocessor list, and legal pages last revised in 2023 while the pricing page is dated March 2026
Pricing & Plans
There is no permanent free plan. A free trial provides a one-off credit of 500 words, and professional associations such as AIE, ADEI and Forum editoria can arrange an unlimited-word trial period for their members. The cheapest paid entry point is EUR 100.00 excluding VAT, that is EUR 122.00 including VAT, which credits a word account with 500,000 words usable for twelve months from the most recent purchase. Larger packs lower the effective price per word, and publisher subscriptions carry no word limit and are quoted individually against annual output.

Data, GDPR & hosting
A consolidated view of how Corrige.it handles your data.
GDPR overview
Implementation is concrete and documented. EuloTech srl publishes an Article 13 notice under Regulation (EU) 2016/679 and the Italian Privacy Code, covering both www.corrige.it and pro.corrige.it. The controller is identified in full: registered office at Terza Traversa G.B. Pirelli, 75100 Matera, Matera company register number 01292030770, REA number MT-87573. A Data Protection Officer is named, Eugenio Mastidoro, reachable at the certified address eulotech@legalmail.it. The notice lists the Chapter III rights, namely access, rectification, erasure, restriction, objection, portability, withdrawal of consent and complaint to the supervisory authority, exercised in writing at the registered office. Users under 16 need parental authorisation under Article 8(1). Profiling cookies are declared absent and Google Analytics is the only third party listed. The page carries a last revision date of 20 July 2023.
Who owns the data?
The published copyright notice draws a clear line. Everything Corrige.it produces belongs to EuloTech srl, the company behind the tool: report layouts, style sheets, trademarks, editorial notes and the XML structure returned by the web service. The portions of the user's own text reproduced inside a report or an annotated PDF are explicitly excluded from that ownership, so authors keep their manuscripts. Users may copy and circulate the reports and annotated PDFs freely, provided they do so in full and in the original layout, without altering, removing or hiding any Corrige.it element. Output delivered through the web service may be used within the contract agreed at subscription.
Reuse rights
Users may reuse what Corrige.it gives back without asking permission, within limits the site sets out plainly. Reports and annotated PDFs can be copied and circulated freely on condition that they remain complete and keep their original layout: nothing may be altered, removed or concealed. Content returned through Corrige.WebService may be used inside the contractual relationship agreed when the web-service subscription is taken out. Anything beyond that is restricted. Copying, reproducing, transferring, archiving, publishing or distributing the site's own content, in whole or in part, requires EuloTech's prior written consent, although downloading and printing single extracts is allowed for strictly personal use or for scientific research and publication.
Data retention & training
Hosting summary
EuloTech states that the site and the reports are served from the cloud infrastructure of leading operators located in Italy or in Europe. The GDPR notice adds that processing connected to the web services takes place at the company's premises, handled by designated technical staff, while the servers themselves may be cloud-managed and sited away from those premises at an internet service provider. No provider is named and no specific data centre is identified. The Area Resoconti, where reports and annotated PDFs are held, sits inside what the company calls the Corrige.it security perimeter. A network check carried out on 31 August 2026 resolved the site to 95.110.149.139, an address operated by Aruba S.p.A. in Arezzo, Italy, with no anycast in evidence, which is consistent with the declaration. Organisations with stricter requirements can install an isolated, self-contained instance on their own premises, with knowledge-base updates handled by agreed procedures that can exclude any internet connection altogether.
Things to keep in mind
Risks and trade-offs to weigh before adopting Corrige.it.
- The homepage promise that Corrige.it does not reuse your texts sits uneasily beside the confidentiality page, which documents sequences of up to ten words being stored automatically in the knowledge base
- Choices made with the Corretta and Errore buttons are kept indefinitely, and the knowledge base they feed is described as serving other projects and services beyond Corrige.it
- No opt-out from that storage is documented anywhere on the site; the only way to keep material entirely inside your own perimeter is the separate on-premise build
- Third-party automated functions may be used to extract text from PDFs, and those third parties are never named
- Leaning on an automated checker can dull the habit of close reading, and the vendor itself warns that no tool can find every error in a text
- Word credits are zeroed at the twelve-month expiry and unused words are not refundable, so buying a large pack ahead of real demand can waste money
- Legal pages carry 2023 revision dates while commercial pages were refreshed in 2026, and the server advertised PHP 5.3.3 when the site was surveyed
Setup & Integrations
Technical difficulty
Low for the online service: there is nothing to install, you simply point the system at a file, and the reports are ordinary web pages that open on any device with JavaScript enabled. The Word 365 add-in takes a few clicks from the Office Store and reuses the same credentials. Only the API needs a developer, since documents must carry a dedicated opening marker and evaluation access is granted on request by email. The real friction is commercial rather than technical, as activating a subscription goes through the editorial desk rather than a checkout.

Should you pick Corrige.it?
Corrige.it is a narrow tool that goes deep. It serves one language and one broad audience, people who publish in Italian, and inside that perimeter it offers something most general-purpose assistants do not: a judgement about whether a correctly spelled word belongs where it sits. The Gulpease readability index, the Vocabolario di base levels and a knowledge base curated daily by linguists give the output an editorial grounding rather than a purely statistical one.
The trade-offs are just as clear. There is no free tier worth the name, buying is a conversation rather than a checkout, and an entry ticket of EUR 100 excluding VAT will deter anyone who writes only occasionally. The delivery surface is narrow too: a website, a Word 365 add-in and an API, with no mobile app and an InDesign add-in that has been announced for some time.
Governance is a mixed picture. The company identifies itself completely, names a Data Protection Officer and publishes a proper Article 13 notice, and hosting is declared in Italy or Europe. But there is no data processing agreement, no subprocessor list, and the legal pages were last revised in 2023 while the pricing page was refreshed in March 2026. The privacy wording repays a careful read: the homepage promises that your texts are not reused, while the confidentiality page documents short word sequences and user choices being stored in the knowledge base, the latter indefinitely.
For a publishing house, a proofreading desk or a technical documentation team working in Italian, the value is easy to see, and the on-premise option answers the strictest procurement questions. For anyone else, the language limit alone will settle the matter.
