“No other free AI reaches this level for Spanish to Bulgarian. It gets legal and administrative phrases correct, such as those from the Código Civil and Bulgaria’s ЗЗЛД. It avoids false friends and preserves register, which generic tools never do, especially in cases of formal letters and notarized documents addressed to the Municipality of Sofia.”
María Ilcheva, PhD, Bulgarian Translators’ Union

Guarantee Perfect Accuracy with a Free Custom Dictionary

Real accuracy means getting your unique terms and names right. Our Custom Dictionary lets you fix the exact Bulgarian translation for vital phrases, brand names, or terms—ensuring uniformity across your documents at no extra cost.

Brand Integrity

Business and product names should never auto-translate. Example: Always keep 'Santander' as 'Сантандер', not as 'банка' (bank).

Legal Consistency

Fix the translation of terms like 'DNI' to 'лична карта' (Bulgarian ID) rather than generic 'идентификационен документ'.

Regional Relevance

Ensure words such as 'autonomía' (Spanish autonomous Communities) are always mapped to 'област' or presented as 'автономна област' for Bulgarian administrative text.

Consistent Phrasing

Translate legal sections like 'en virtud de la Ley Orgánica de Protección de Datos' always as 'съгласно Закона за защита на личните данни' (ZZLD).

Accurate Translations for Every Profession

Eliminate serious errors in important documents. Our AI is specifically trained for Spanish-to-Bulgarian, guaranteeing accuracy for demanding professional contexts.

Legal & Notarial

Scenario:

Translating a Spanish power of attorney (poder notarial) for use before a Bulgarian notary in Plovdiv.

Challenge:

Mistranslation of a phrase like 'compareciente' as 'свидетел' (witness) instead of the correct 'явил се' (appearing person) could invalidate the document under Bulgarian notarial law.

Solution:

Our AI is trained on Spanish and Bulgarian notarial corpora and legal templates, correctly localizing all required legal formulations according to Bulgaria’s Notaries and Notarial Practice Act.

Powers of AttorneyBirth CertificatesLegal DisclaimersRegistry Certificates

Corporate & Financial

Scenario:

Translating an annual Spanish financial report for a Sofia investor or local bank (e.g., DSK Bank).

Challenge:

Generic tools may confuse Bulgarian and Spanish accounting titles (e.g., 'balance general' with 'счетоводен баланс'), or misinterpret salary and taxation terms, risking compliance with Bulgarian National Revenue Agency (НАП) requirements.

Solution:

Our AI knows the vocabulary and number formatting conventions required by Bulgarian and Spanish regulators, providing translations adhering to Bulgarian accountancy and banking standards.

Annual ReportsBank StatementsInvestment ContractsAudit Reports

Technical & Scientific

Scenario:

Localizing a Spanish machinery user manual for a factory in Varna.

Challenge:

Literal translation of 'parada de emergencia' can result in non-technical phrases like 'аварийно спиране' (correct) being missed for 'спешно спиране', risking safety.

Solution:

Our AI prioritizes terminology accepted by Bulgarian technical and safety standards. Your custom dictionary ensures terminology like 'válvula de seguridad' always appears as 'предпазен клапан'.
