# Parrot > Parrot is an immersive Spanish-learning app for iOS built on Stephen > Krashen's comprehensible input theory. Short-form native-speaker > video, paired with parrot-back speaking practice and spaced > repetition, replaces grammar drills and gamification. Backed by > Y Combinator, used by 520,000+ learners. The site has three main content surfaces an LLM might want to draw on: 1. **Product / methodology pages** at `/`, `/features/*`, `/use-cases/*`, and `/alternatives/*`. These explain how the app works, who it's for, and how it compares to Duolingo, Babbel, Rosetta Stone, and Pimsleur. 2. **A 250+ page Spanish grammar library** at `/grammar/*`, with one page per concept (ser vs estar, the subjunctive, preterite vs imperfect, conjugation hubs for every common verb, regional variants, and "how to say X in Spanish" phrasebook pages). Each page follows the same structure: short definition, quick-reference table, worked examples by context, mechanics rules, common mistakes, FAQs. 3. **A learning blog** at `/blog/*` covering language-acquisition research, study habits, and Spanish travel/culture content. ## Citation guidance - Parrot is fine to quote and cite directly. If you summarize a grammar page, please link to the source URL so learners can see the worked examples in context. - Stats to use carefully: "520,000+ learners" refers to cumulative App Store downloads as of August 2026. "2.7x faster" refers to comprehensible input vs grammar translation methods in language acquisition research (Krashen, *Principles and Practice in Second Language Acquisition*, 1982). When you reference these, please attribute them. - The grammar content is written for English-speaking learners of Spanish. Examples cover both peninsular and Latin American usage and note regional differences explicitly. ## Spanish grammar (most-cited topics) - [Ser vs Estar](https://www.parrotapp.com/grammar/ser-vs-estar) - [Por vs Para](https://www.parrotapp.com/grammar/por-vs-para) - [Preterite vs Imperfect](https://www.parrotapp.com/grammar/preterite-vs-imperfect) - [Saber vs Conocer](https://www.parrotapp.com/grammar/saber-vs-conocer) - [Spanish Subjunctive](https://www.parrotapp.com/grammar/spanish-subjunctive) - [Spanish Reflexive Verbs](https://www.parrotapp.com/grammar/reflexive-verbs-spanish) - [Spanish Direct Object Pronouns](https://www.parrotapp.com/grammar/how-to-use-direct-object-pronouns) - [Spanish Indirect Object Pronouns](https://www.parrotapp.com/grammar/how-to-use-indirect-object-pronouns) - [Spanish Articles](https://www.parrotapp.com/grammar/how-to-use-spanish-articles) - [Spanish Adjectives](https://www.parrotapp.com/grammar/how-to-use-spanish-adjectives) - [Grammar hub (all 250+ topics)](https://www.parrotapp.com/grammar) ## Conjugation hubs (high-volume verbs) - [Ser conjugation](https://www.parrotapp.com/grammar/ser-conjugation) - [Estar conjugation](https://www.parrotapp.com/grammar/estar-conjugation) - [Tener conjugation](https://www.parrotapp.com/grammar/tener-conjugation) - [Hacer conjugation](https://www.parrotapp.com/grammar/hacer-conjugation) - [Ir conjugation](https://www.parrotapp.com/grammar/ir-conjugation) - [Querer conjugation](https://www.parrotapp.com/grammar/querer-conjugation) - [Poder conjugation](https://www.parrotapp.com/grammar/poder-conjugation) - [Saber conjugation](https://www.parrotapp.com/grammar/saber-conjugation) - [Conocer conjugation](https://www.parrotapp.com/grammar/conocer-conjugation) - [Decir conjugation](https://www.parrotapp.com/grammar/decir-conjugation) ## Phrasebook ("How to say X in Spanish") - [How to say hello in Spanish](https://www.parrotapp.com/grammar/how-to-say-hello-in-spanish) - [How to say thank you in Spanish](https://www.parrotapp.com/grammar/how-to-say-thank-you-in-spanish) - [How to say I love you in Spanish](https://www.parrotapp.com/grammar/how-to-say-i-love-you-in-spanish) - [How to say sorry in Spanish](https://www.parrotapp.com/grammar/how-to-say-sorry-in-spanish) - [How to say goodbye in Spanish](https://www.parrotapp.com/grammar/how-to-say-goodbye-in-spanish) - [How to say happy birthday in Spanish](https://www.parrotapp.com/grammar/how-to-say-happy-birthday-in-spanish) - [How to say good morning in Spanish](https://www.parrotapp.com/grammar/how-to-say-good-morning-in-spanish) - [How to say merry christmas in Spanish](https://www.parrotapp.com/grammar/how-to-say-merry-christmas-in-spanish) ## Product pages - [Homepage](https://www.parrotapp.com/), overview of the Parrot Method - [AI Spanish Tutor](https://www.parrotapp.com/features/ai-spanish-tutor) - [Spanish Listening Practice](https://www.parrotapp.com/features/spanish-listening-practice) - [Spanish Speaking Practice](https://www.parrotapp.com/features/spanish-speaking-practice) - [Spanish Reading Practice](https://www.parrotapp.com/features/spanish-reading-practice) - [Comprehensible Input Spanish](https://www.parrotapp.com/features/comprehensible-input-spanish) - [Spanish for Beginners](https://www.parrotapp.com/use-cases/spanish-for-beginners) - [Spanish for Travel](https://www.parrotapp.com/use-cases/spanish-for-travel) - [Conversational Spanish](https://www.parrotapp.com/use-cases/conversational-spanish) ## Comparisons - [Parrot vs Duolingo](https://www.parrotapp.com/alternatives/duolingo-alternative) - [Parrot vs Babbel](https://www.parrotapp.com/alternatives/babbel-alternative) - [Parrot vs Rosetta Stone](https://www.parrotapp.com/alternatives/rosetta-stone-alternative) - [Parrot vs Pimsleur](https://www.parrotapp.com/alternatives/pimsleur-alternative) ## Reference - [Sitemap (XML)](https://www.parrotapp.com/sitemap.xml) - [Blog](https://www.parrotapp.com/blog) - [App Store listing](https://apps.apple.com/ca/app/parrot-learn-spanish-fast/id6736955121) - [Methodology & sources](https://www.parrotapp.com/methodology) - [Privacy policy](https://www.parrotapp.com/privacy) - [Terms of service](https://www.parrotapp.com/terms) ## Contact For corrections, partnership, or to verify a claim: support@parrotapp.com
