# 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 687,552+ learners.
The site has four 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. **Grammar libraries for other languages** built on the same template:
French at `/french/grammar/*` (with verb conjugations at
`/french/verb-conjugations/*`) and English at `/english/grammar/*`
(tenses, modals, verb forms, nouns and articles, adjectives and
adverbs, prepositions, sentence structure; each page adds a form table
and a quick check). Section hubs: `/french/grammar`, `/english/grammar`.
4. **An English pronunciation guide** at `/english/pronunciation/*`: one
page per word with a plain-English respelling, IPA for American and
British English (from CMUdict and ipa-dict, not generated), syllable
stress, a definition, example sentences, and common mispronunciations.
Letter indexes at `/english/pronunciation/words-starting-with-{a-z}`.
5. **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: "687,552+ learners" is the exact number of
unique people who have opened the app since launch (iOS, Android, and
web), as measured by RevenueCat and recorded on 2026-10-17; it is
republished every day and defined in full at
https://www.parrotapp.com/methodology#learner-count. "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.
