Check your Spanish grammar instantly with AI-powered feedback. WriteIn Spanish helps you identify and correct errors in verb conjugation, ser vs estar, por vs para, and more—essential for mastering Spanish writing.
Start Checking Your GrammarSpanish grammar presents unique challenges for learners, from the complexities of verb conjugation to the subtle distinctions between ser and estar, or por and para. Even advanced speakers struggle with the subjunctive mood, pronoun placement, and the nuances of different past tenses.
Whether you're a student preparing for exams like the DELE, AP Spanish, or SIELE, a professional writing business correspondence, or a language enthusiast improving your skills, accurate Spanish grammar is essential for clear communication and academic success.
WriteIn Spanish provides AI-powered grammar checking that helps you identify and understand your mistakes. Rather than just marking errors, our tool helps you learn why something is incorrect and how to fix it, accelerating your path to Spanish fluency.
WriteIn Spanish is designed to identify the grammar mistakes that Spanish learners make most frequently:
Both verbs mean "to be," but they're used in different contexts. Ser is for permanent characteristics, while estar is for temporary states and locations. Our tool catches misuse of both verbs.
These prepositions both translate to "for," but have distinct uses. Por indicates cause or duration, while para indicates purpose or destination. We identify when you've used the wrong one.
Spanish verbs change form based on tense, mood, and subject. Our tool catches mistakes in present, preterite, imperfect, future, conditional, and subjunctive conjugations.
Every Spanish noun has a gender (masculine or feminine), and adjectives must agree. We identify agreement errors between nouns, adjectives, and articles.
Both are past tenses with different uses. Preterite is for completed actions, imperfect for ongoing or habitual past actions. Our checker helps you use the right tense.
The subjunctive expresses doubt, wishes, emotions, and uncertainty. We catch errors in when to use subjunctive and how to conjugate it correctly.
Here are real examples of the types of errors WriteIn Spanish helps you identify and correct:
❌ Incorrect: La fiesta es en mi casa.
✅ Correct: La fiesta está en mi casa.
Explanation: Use "estar" for location, not "ser". Ser is for permanent characteristics, estar is for location and temporary states.
❌ Incorrect: Estudio por ser médico.
✅ Correct: Estudio para ser médico.
Explanation: Use "para" to express purpose or goal. "Por" indicates cause, duration, or exchange.
❌ Incorrect: Cuando era joven, fui a Madrid una vez.
✅ Correct: Cuando era joven, fui a Madrid una vez.
Note: This is actually correct! "Era" (imperfect) describes an ongoing state ("when I was young"), while "fui" (preterite) describes a one-time completed action.
❌ Incorrect: La problema difícil.
✅ Correct: El problema difícil.
Explanation: "Problema" is masculine despite ending in -a, so it requires "el" not "la".
❌ Incorrect: Espero que tú tienes un buen día.
✅ Correct: Espero que tú tengas un buen día.
Explanation: After "espero que" (expressing a wish), you must use the subjunctive mood "tengas," not the indicative "tienes."
❌ Incorrect: Yo voy a decir te la verdad.
✅ Correct: Yo voy a decirte la verdad.
Explanation: Object pronouns attach to infinitives as one word, not separated.

The subjunctive is one of the most difficult Spanish grammar topics for learners. Our tool helps you identify when the subjunctive is required (after expressions of doubt, wish, emotion, or uncertainty) and catches conjugation errors in subjunctive forms.
Knowing when to use preterite (completed actions) versus imperfect (ongoing/habitual actions) is crucial for correct Spanish writing. Our AI helps you choose the right past tense for your context.
The conditional and future tenses have different uses and conjugation patterns. We catch errors in formation and usage of both tenses, including irregular future stems.
Spanish has separate direct (me, te, lo, la, nos, los, las) and indirect (me, te, le, nos, les) object pronouns with specific placement rules. We identify incorrect pronoun usage and placement.
Reflexive verbs require reflexive pronouns (me, te, se, nos, se) that agree with the subject. Our tool catches missing or incorrect reflexive pronouns.
Spanish commands have different forms for tú, usted, nosotros, and vosotros, with different rules for affirmative and negative commands. We help you use the correct command form.
