Frequently asked questions
FAQ
Frequently asked questions
What is a contract analyzer?
A contract analyzer examines an agreement for important terms, obligations, costs, deadlines, risks and missing information. Aletura uses a predefined structured methodology rather than relying on a single summary prompt.
How does Aletura scan a contract?
Aletura extracts native text and uses local OCR only for image-bearing PDF pages that need it. OCR text must pass a readability check, then detected personal identifiers are masked before any text is sent for AI analysis. Unreadable pages make the analysis incomplete rather than silently disappearing.
Can Aletura identify automatic renewal and cancellation deadlines?
Yes, those are explicit review topics. If the evidence is missing, contradictory or depends on another document, the report keeps that uncertainty visible instead of treating silence as safety.
Can Aletura compare two contracts?
Yes. You can compare two or three documents. Aletura checks whether they are likely versions, same-type offers, related documents or different contract types before deciding how detailed the comparison can be.
Which contract types can Aletura analyse?
Aletura has specialist frameworks for rental, leasing, purchase, services, membership, SaaS, NDA, employment and consulting, financing and insurance agreements. Unknown documents receive universal and general checks.
Which languages does Aletura support?
This website is available in English and German. Reports are available in English, German, French and Italian; French and Italian were newly added on 2026-11-03 and are pending benchmark validation. Other detected source languages use English reports where processing is possible. Source evidence stays in its original language. Detailed validation status is published with the methodology: Methodology & validation.
Does Aletura store my contract?
Not by default. Guest work is not saved, and signed-in work remains temporary until you choose Save. Save analysis retains the masked structured result without the source file. Save contract & analysis deliberately retains the original source under your account or workspace policy. Identifier mappings and temporary indexes are never retained.
Does Aletura replace a lawyer?
No. Aletura helps you understand contractual text and identify points that may deserve attention. It does not determine enforceability, predict a court outcome or provide legal strategy.
Can I ask questions after the analysis?
Yes. Ask Aletura uses a plan-controlled question allowance: Guest and Individual default to five, while own-key and Business policies can differ. It does not reread the original contract or override validated contractual facts.
Can Aletura review German, SaaS and rental agreements?
Yes, report output in English, German, French and Italian is configured, and SaaS and rental agreements each have specialist frameworks. Current language certification is not yet validated by a complete benchmark — see Methodology & validation.
PRIVACY + EVIDENCE
Designed to minimize data exposure.
Detected personal details are masked before AI processing. Automatic detection has limits: upload only the information needed for the review.
Aletura provides structured information, not legal advice.
Privacy in detail
Guest use requires no account and creates no saved contract or report. Account and quota metadata are separate from contract-content storage. Signed-in analyses remain temporary unless you explicitly choose Save. Save analysis retains the masked structured result; Save contract & analysis also retains the original source under account or workspace authorization. Unmasked extracted text, identifier mappings and temporary indexes are not retained.
Detected personal identifiers become request-scoped placeholders before Mistral processing. Optional restoration happens locally after the response.
Original uploads remain temporary unless you deliberately choose Save contract & analysis. Save analysis retains only the masked structured result.
Important findings retain source references, and quoted evidence remains in its original language.
The default endpoint is https://api.eu.mistral.ai, configured for Mistral EU regional inference; a regional endpoint alone does not establish complete end-to-end residency.
Review contracts in their original language.
This website is available in English and German. Reports are available in English, German, French and Italian; French and Italian reports were newly added on 2026-11-03 and are pending benchmark validation; other detected source languages use English reports where processing is possible. Evidence stays in its original wording. End-to-end language quality is not yet independently validated. Methodology and current validation status.
Detection has limits. Automated masking cannot guarantee that every sensitive value will be identified. Avoid uploading highly sensitive information that is not necessary for contract analysis.

Which documents can I compare?
Versions of the same agreement and contracts of the same type can be compared in detail. Related, different or uncertain document types receive a general overview. Differences between contract types are not presented as improvements or deterioration between versions.
Upload order stays visible
