METHOD

Preparation. Extraction. Review.

Several models review form and substance independently — identical schema, low temperature, one consensus from it. The substantive processing runs in EU regions, spelling additionally locally and deterministically.

  1. 01

    Preparation

    The PDF is prepared into clean, structured text via OCR — layout, tables and footnotes are recognised.

  2. 02

    Extraction

    Content is pulled out deliberately: the line of argument, evidence, citations and the reference apparatus — the basis for a well-founded review.

  3. 03

    Review

    Seven review layers analyse form and substance independently. A consensus brings the findings together, deduplicates, separates finding from suggestion and calibrates severity.

  4. 04

    Delivery

    An annotated PDF with inline findings, severity in three levels and a rationale per passage — the content stays untouched.

LEVEL CALIBRATION

Bachelor's, Master's and dissertations are not treated the same: the review standard and the wording of the feedback scale with the level — from solid fundamentals and easy-to-apply suggestions to whole-work review (coherence across many chapters, consistency across a large reference apparatus, a publication-ready register).

SUITABLE FOR
  • Bachelor's and master's theses
  • Dissertation chapters, cumulative work
  • Journal articles pre-submission
  • Seminar and term papers
NOT SUITABLE
  • Plagiarism checks
  • AI detection or humanising
  • Ghostwriting, content additions
  • Translation, fact-checking
§ 04
PRIVACY

Privacy, transparent.

Maximum model power, processed in EU regions — every provider under a data-processing agreement (DPA). Transparent about where data sits and where the residual risk is.

Lektoria processes with European or EU-region providers. There is a data-processing agreement under Art. 28 GDPR with each one; for Google Cloud as a US-based group, EU Standard Contractual Clauses and certification under the EU-US Data Privacy Framework apply in addition. The AI processing runs exclusively in an EU region of Vertex AI; inputs are not used to train the models, and only metadata is logged (no document content). Spelling is checked by a deterministic engine locally on our server in Falkenstein.

Processing in EU regions does not in every case fully exclude access by an authority from a third country (e.g. under the US CLOUD Act). We disclose this residual risk and secure transfers via EU Standard Contractual Clauses and the EU-US Data Privacy Framework — details in the privacy policy.

FAQ

Common questions.

More questions: info@lektoria.eu

01What does proofreading cost?
Flat price per file, no subscription: three packages — Basic €50, Plus €75, Premium €150. The package sets scope and price; the level (Bachelor's, Master's, dissertation) calibrates review depth and costs nothing extra. Paid once via Stripe, delivered once.
02What is the difference between proofreading and editing?
Proofreading covers spelling, grammar and punctuation only. Editing goes further and also checks form, wording, style, the line of argument and citation. Lektoria delivers both: deterministic spell-checking plus an AI consensus edit for form, language and structure — without rewriting your content.
03Is AI-assisted editing allowed for my thesis?
Editing of form, language and structure is common and permitted at universities: Lektoria phrases suggestions but writes no content, adds nothing and does no ghostwriting — authorship remains entirely with the submitting person. Neither facts nor originality are assessed. The rules of your university or examination regulations on the use of aids apply in addition.
04How does the review differ for Bachelor's, Master's and dissertations?
The review itself is equally thorough for everyone: every layer looks for the same weaknesses in every thesis — a flaw is a flaw, whether it's a Bachelor's thesis or a dissertation. The level then sets the grading standard: the same finding that counts as optional fine-tuning for a Bachelor's thesis is classed as recommended for a Master's and as required for a dissertation. Some expectations don't apply at lower levels at all — an original research contribution is only expected of a dissertation. Every thesis gets the same rigour, judged against a standard that is fair for its degree.
05Does my data leave the EU?
The actual processing runs in EU regions; spelling is checked by a deterministic engine locally on our server in Falkenstein. Some processors belong to US groups — access by US authorities (CLOUD Act) cannot be excluded 100 % despite EU processing. We secure this via EU Standard Contractual Clauses, the EU-US Data Privacy Framework and data-processing agreements, and we disclose the residual risk together with the full processor list in the privacy policy.
06Is my text used for training?
Contractually not: inputs and outputs are not used to train the models. Storage is governed per processor — from no persistent storage (Zero Data Retention) to a short window for abuse monitoring within the EU. Provider-level details and references are in the privacy policy.
07What happens to the file after the review?
You download your report yourself for 90 days from the password-protected export area (login with email + self-chosen password); after that it is deleted automatically, as is your uploaded file. Earlier deletion is possible at any time. The invoice is kept for 8 years as legally required — separately from the content.
08Why don't I receive the report by email?
Because email is not an encrypted channel. To keep your document protected, we deliberately do NOT send the report as an attachment — the email contains only a login link. You download the report itself from the password-protected export area, which only you can reach with your email and password. Security matters more to us than convenience.
09How long does a run take?
Usually within 90 minutes regardless of length — often considerably faster. Your thesis goes through several independent reviews (spelling, formal criteria, language and structure) whose results are then cross-checked and merged into one report. That quality standard takes time. As soon as the report is ready, we notify you by email with a login link — you then download it from the password-protected export area.
10Which file formats do you accept?
PDF only, with a real, selectable text layer. We deliberately no longer accept Word/DOCX or ODT — converting them costs layout and formatting fidelity that matters for editing. Scanned or photographed PDFs without a text layer are rejected.
11What if the review fails?
You get your money back — automatically. If processing fails or takes too long, the full amount is refunded via Stripe without you having to do anything, and you receive an e-mail notification. No forms, no chasing anyone.
