The details nobody corrects

Daily practice for people who already speak Spanish and were never systematically corrected. One card at a time, with an explanation every time – why, not just whether.

Free. One email, then nothing.

B1Intermediate

COMPLETA LA FRASE

El año pasado ___ a España de vacaciones.

  • viajé
  • viajaba
  • viajo
  • viajaré

CORRECTO

'viajé' – preterite for a single completed past trip.

Every card tells you why

Right or wrong, the explanation is there. Fossilized errors survive because nothing draws attention to them any more – so Frasero draws attention, every time.

C1Advanced

COMPLETA LA FRASE

No iré a la fiesta a menos que ___ mi hermano también.

  • va
  • vaya
  • irá
  • iba

CASI

'vaya' – 'a menos que' (unless) is a fixed conjunction that always takes the subjunctive.

The ones you miss come back

Get something wrong and it returns on a spaced schedule, not at the end of a lesson. You stop when you stop; the missed card is already booked in.

B2Upper intermediate

COMPLETA LA FRASE

Si ___ más tiempo, viajaría por todo el mundo.

  • tuviera
  • tengo
  • tendré
  • tenía

CASI

'tuviera' – a hypothetical 'si' clause paired with a conditional takes the imperfect subjunctive.

Six ways of being asked

Fill the gap, pick between two forms that both look right, build the sentence, match the word. The same grammar from different angles, so you can't pattern-match your way through.

B2Upper intermediate

ELIGE LA FORMA CORRECTA

Busco un empleado que ___ tres idiomas con fluidez.

  • hable
  • habla

CORRECTO

'hable' – the antecedent is unknown or sought, so the relative clause takes the subjunctive.

Tell us when a card is wrong

You speak Spanish. If an exercise is off – the sentence, the options, the explanation – flag it from the card itself and it reaches a person who can fix it.

B1Intermediate

¿QUÉ PALABRA ES?

  • montaña
  • playa
  • ciudad
  • bosque

Report this card

Tell us what's wrong and we'll fix the card.

  • The sentence or question
  • The options or the answer
  • The explanation
  • The translation

More than 1,000 cards. Every one of them explains itself.

Written and cross-checked by machine, then read by a native Spanish speaker who teaches the language – in one language pair only, and reportable from inside the app the moment one of them is wrong.

COMPLETA LA FRASE

Estaba completamente agotado; ___, terminó el informe esa misma noche.

  • por lo tanto
  • por eso
  • así que
  • no obstante

CASI

'no obstante' – the clause contrasts exhaustion with finishing, so it needs a concessive connector; the others express consequence.

Where it sits
The level this card is pitched at. The ladder decides what you are shown.
The sentence
A real item, asked in Spanish, with its seed id intact.
What you picked
Shown against what was right. Both marked, neither hidden.
The reason
On every card, right or wrong. This is the part that does the work.

Scroll until the Spanish stops being easy
