Cavya
An AI localization platform bundling four tools for translation teams: terminology extraction, style guide creation, document analysis and rule-based plus AI quality assurance. Runs on credits, no subscription, with ten credits granted at sign-up.
What is Cavya?
Cavya is an AI localization platform published by Milestone Localization Private Limited, a Bangalore company with a UK subsidiary. It does not translate: it takes on the preparation and verification work that surrounds a translation project, through four tools sharing a single account and a single credit balance.
CavyaQA is the quality assurance module. It runs the structural checks a traditional QA tool performs, tags, numbers, formatting and consistency, then layers context-aware AI analysis on top: grammar, agreement, register, awkward phrasing, glossary and style guide deviations, inconsistent renderings, gender instructions ignored, wording unsuitable for the audience. Nine such error families are illustrated on the product page, each with a proposed correction rather than a bare flag. It accepts XLIFF, SDLXLIFF, MQXLIFF, MXLIFF and bilingual CSV.
The Glossary Generator pulls acronyms, product and brand names, technical jargon and regulatory references out of a document, returns each term with its usage context in a type / term / context layout, and translates the list into more than 120 languages.
The Style Guide Creator reads your file and produces a guide covering audience and accepted language variants, terminology, punctuation, dates, times, currencies, measurement units, acronyms, brand names, tone, inclusivity and the treatment of figures and layouts. It is delivered as an editable Word document with examples.
The Smart Document Analyzer identifies language, dialect, content type, structure and audience, rates complexity, flags regulatory cues and risks such as terminology gaps or text embedded in images, scores translation difficulty and recommends a linguist profile and a workflow.
Everything runs in the browser at app.cavya.ai, with no installation. Fifteen-plus file formats are accepted for the glossary, style guide and analysis modules, including patents, IFUs, technical manuals, Office files, PDF, TBX, XLIFF and PO. Source documents do not have to be in English. Files are encrypted and hashed, readable by their owner alone, and the publisher states they never train any model. Around 700 translation teams are claimed as users.
What it does
- Run rule-based and AI quality checks on translated bilingual files and get suggested corrections
- Extract key terms from a document with their context and translate them into 120+ languages
- Generate a structured, editable translation style guide as a Word file
- Analyse a source document for complexity, required expertise, risks and regulatory content
- Check translations against a custom style guide and glossary and flag every deviation
- Work on source files in languages nobody on the team reads
- Batch several project files at once instead of handling them one by one
When to use Cavya / When not to
A quick filter to help you decide if Cavya is the right fit.
When to use Cavya
- Freelance translators who prepare glossaries and terminology lists before every project
- Localization managers standardising style, tone and terminology across markets
- Translation project managers scoping file complexity and picking the right linguist
- Reviewers and LQA specialists running quality checks on bilingual XLIFF or CSV files
- Content teams handling regulated or NDA-bound documents such as patents, IFUs and technical manuals
When not to use Cavya
- Anyone looking for a machine translation engine: Cavya prepares and checks work, it does not translate documents
- Teams that need the tool wired into a CAT tool or TMS, since no API and no named integration are published
- Reviewers whose QA files are plain DOCX or PDF, as CavyaQA only accepts XLIFF, SDLXLIFF, MQXLIFF, MXLIFF or bilingual CSV
- Organisations that require a signed data processing agreement, an EU representative or a named DPO before onboarding a vendor
- Buyers who want an unlimited free tier or a refund policy, since the ten starter credits are one-off and purchases are final

Pros & Cons
Pros
- Four complementary tools cover the whole project preparation and verification cycle from one account
- Substantial time savings claimed by the publisher: glossaries from two to six hours down to minutes, style guides from six to eight hours down to minutes
- QA proposes fixes rather than only flagging problems, which shortens review cycles
- Clear confidentiality stance: encryption, hashing, owner-only access and no model training, with the processor list published in full
- Credits never expire, no subscription is imposed, and ten credits let you test without a card
- Multilingual source files can be processed by teams that do not read the source language
- Entirely cloud-based, so there is nothing to install or maintain
Cons
- No public API and no named integration, so nothing plugs into an existing CAT or TMS pipeline
- CavyaQA only ingests bilingual formats: XLIFF, SDLXLIFF, MQXLIFF, MXLIFF or CSV
- No permanent free plan; the ten opening credits are a one-off trial and purchases are non-refundable
- No published DPA, no named DPO and no Article 27 representative, which will slow down European procurement
- The homepage claims no file storage after processing while the privacy policy describes hashed storage, a contradiction left unresolved
- The list of the 120+ supported languages is never published, and no security certification such as SOC 2 or ISO 27001 is claimed
- Indian governing law and exclusive jurisdiction in Bangalore, with no mobile app and a product the publisher itself calls newer than established QA software

Data, GDPR & hosting
A consolidated view of how Cavya handles your data.
GDPR overview
Cavya states plainly that it complies with the GDPR and the CCPA. The privacy policy, in force since 22 May 2025, lists the rights it recognises: access, rectification, erasure, restriction or objection, portability and withdrawal of consent, exercised through account settings or by writing to support@cavya.ai. It names its processors, among them Anthropic, OpenAI, Stripe, Google, Supabase, Vercel, GenLeads and Twilio, and rules out any training on customer content. Weak points remain. No data processing agreement is published, no data protection officer is named, and no Article 27 representative is designated even though the publisher is established in India with a UK subsidiary. International transfers to India and the United Kingdom are announced without standard contractual clauses, and the policy warns that changes will not be notified.
Who owns the data?
Users keep full ownership of everything they upload or generate. The terms grant the publisher a non-exclusive, royalty-free, worldwide and perpetual licence to use, copy, modify and display that content, but strictly to deliver the service. Uploaded files are stored in hashed or anonymised form and, according to the privacy policy, are reachable only by the account that uploaded them, not by other users nor by the publisher's own system administrators. Content is passed to named AI providers for processing, under agreements that forbid them from keeping or reusing it afterwards. No file is used to train any model.
Reuse rights
Whatever you generate with Cavya, glossaries, style guides, analysis reports and QA findings, is yours to reuse commercially without asking permission: the terms confirm you retain all ownership rights over the content you submit or create, and the licence you grant back is limited to running the service. The style guide is deliberately shipped as an editable Word file meant to be reviewed, amended and shared with clients or linguists. Two limits apply on the other side of the account: the publisher processes personal data such as name, email and payment identifiers for support, analytics, product development and marketing, and it may transmit uploaded content to third-party AI providers for the sole purpose of fulfilling a request. Credits themselves are not transferable, are non-refundable and are forfeited if the account is closed.
Data retention & training
Hosting summary
The privacy policy states that information is stored and processed in India and the United Kingdom, and potentially in any other country where the publisher's service providers keep servers. That list is explicit and mostly American: Anthropic, OpenAI, Stripe, Google, Supabase, Vercel, GenLeads and Twilio. The site itself is served behind Google Cloud infrastructure on an anycast address. No hosting region can be chosen by the customer, no data residency is guaranteed, and the policy asks users to accept international transfers simply by submitting their information, without mentioning standard contractual clauses or any other transfer mechanism. Jurisdiction follows the publisher: Milestone Localization Private Limited is an Indian company, its terms are governed by Indian law, and its UK subsidiary does not create an establishment inside the European Union.
Things to keep in mind
Risks and trade-offs to weigh before adopting Cavya.
- Purchased credits are final: nothing is refunded, and any unused balance is forfeited when the account is closed
- The publisher states it may change the privacy policy and the terms without notifying users, so the deal you agreed to can quietly move
- The licence granted over your content is worldwide and perpetual, even though it is limited to delivering the service
- Disputes fall under Indian law and the exclusive jurisdiction of the courts in Bangalore, a real cost for a European or American client
- The site contradicts itself on retention, promising no file storage after processing while describing hashed storage in the privacy policy
- Relying on AI-suggested corrections without a human reviewer erodes the linguist's own judgement, and the publisher itself warns that AI-generated content may contain errors
- GenLeads and Twilio appear among the processors, so personal data also feeds marketing and outreach, not only the product
Setup & Integrations
Technical difficulty
Minimal. Cavya is a browser-based service with nothing to install, no API key and no connector to configure. You create an account at app.cavya.ai, receive ten credits without entering a card, then follow a three-step path: upload a document, pick source and target languages, run the scan and download the result. The publisher advertises a first analysis in under five minutes. The only real preparation is having files in an accepted format, which matters for CavyaQA since it requires bilingual XLIFF, SDLXLIFF, MQXLIFF, MXLIFF or CSV rather than ordinary office documents.

Should you pick Cavya?
Cavya answers a narrow but very real complaint from localization teams: the hours swallowed by project preparation before a single word is translated. Its four modules, glossary extraction, style guide generation, document analysis and combined rule-based plus AI quality assurance, all sit upstream and downstream of translation rather than replacing it, and the publisher is honest enough to say so. The credit model is unusually straightforward: ten credits to try without a card, then USD 10 for forty more, with no subscription and no expiry date. For a freelance translator or a small agency, the barrier to a genuine test is close to zero.
The confidentiality stance is the other strong point. Encryption, hashed storage, owner-only access, an explicit refusal to train models on customer content and a named list of processors amount to more transparency than many larger vendors offer. It matters here, since localization work routinely involves patents, medical instructions for use and pre-release material.
The reservations are structural rather than cosmetic. There is no API and no named integration, so Cavya sits beside your CAT tool instead of inside it, and CavyaQA only reads bilingual files. No data processing agreement is published, no data protection officer is named and no Article 27 representative is designated, which is a genuine obstacle for a European buyer despite the declared GDPR compliance. The homepage claim that nothing is stored after processing sits awkwardly beside a privacy policy describing hashed storage, and that deserves a direct question to the publisher. Credits are also final: nothing is refunded, and unused credits vanish if you close the account. Worth trying, worth reading the terms first.
