    Our Story

    Why We Built Nest English

    Most free English tests fall into one of two camps: short quizzes too brief to mean much, or longer tests that gate real feedback behind a sign-up form or a payment. We wanted something different — a genuinely adaptive diagnostic across five skills, with a report you can actually keep, that never asks for your email.

    Our Approach

    A simple adaptive ladder adjusts difficulty per answer across grammar, vocabulary, reading, listening and speaking, then maps your composite score onto public CEFR/IELTS/TOEFL-style ranges — clearly labeled as an estimate, never as a certified score.

    What We Believe

    Practice should respect your time and your privacy. No inflated stats, no fake testimonials, no data leaving your browser — just a tool that tells you, honestly, where you stand and what to practice next.

    Meet Professor Hoot

    Professor Hoot is the wise little owl who guides the tour and keeps an eye on your streak. He never grades you, never judges a wrong answer, and — true to the species — is suspiciously alert if you happen to be studying between midnight and 4 AM.

    Nest English is an independent project, built and maintained as a single self-contained file that runs entirely in your browser.

    Short Guides

    A few honest, practical reads about English testing and learning.

    Local Performance Ledger

    Practice Hub

    Daily tools to build your level between diagnostics — every session earns XP.

    Interactive Studio

    NEW

    Four new ways to practice — stories, speaking, flip cards and role-play.

    Proficiency Check

    Complete the Missing Halves

    The first sentence is untouched. After that, the second half of every other word is removed. Type only the missing letters — or the whole word, either works. Two short texts, about four minutes.

    Pick a level

    Long Reading

    Read a Full-Length Text

    Real reading means holding an argument across paragraphs. Read at your natural pace, tap when you finish, then answer six questions. The text stays visible — this measures reading, not memory.

    Pick a level

    Vocabulary Flashcards 0 / 0

    Grammar Reference

    30 essential grammar points, explained simply with one example each. Tap any topic to expand it.

    Reading Passages

    Choose a Passage

    Writing Practice

    Respond to the Prompt

    Two layers: an instant local checklist (length, repetition, variety) and an optional AI CEFR estimate — indicative, not a certified score.

    Level:
    0 words
    Free Speaking Practice

    Pick a Prompt & Read Aloud

    Transcribed by your browser's own speech engine. We store nothing.

    AI Speaking

    Speak freely, get an AI estimate

    Practice the interactive question types on demand. This is practice only — it does not affect your test result.

    How Your Score Is Calculated

    No black box. Here is exactly how the engine turns your answers into a level estimate — so you can judge the result for yourself.

    1 A six-level adaptive ladder

    Every question is tagged with one of six CEFR levels — A1, A2, B1, B2, C1 and C2. Answer correctly and the next question steps up a level; miss it and it steps down. This pinpoints your real level in fewer questions.

    2 A statistical best-fit estimate

    Each question carries a difficulty score based on its CEFR level. Your result is the ability level that best explains your actual pattern of right and wrong answers — a Maximum Likelihood estimate — so a single lucky guess or slip barely moves it.

    3 Five skills, then one score

    Grammar, vocabulary, reading, listening and speaking are scored separately, then averaged into a single overall percentage. Skipping a module simply leaves it out of the average.

    4 Mapped onto public scales

    Your overall percentage is mapped onto publicly referenced CEFR bands and approximate IELTS/TOEFL ranges, shown in the table below.

    5 A confidence margin

    A ± margin is estimated from how many questions you answered and how consistent your skills were. More questions and more even skills produce a tighter, more reliable range.

    Score → level mapping

    Overall % CEFR IELTS TOEFL iBT
    0–19A12.0–3.00–30
    20–39A23.5–4.031–44
    40–54B14.5–5.045–58
    55–69B25.5–6.559–78
    70–84C17.0–7.579–95
    85–100C28.0–9.096–120

    These mappings are approximate public comparisons for self-guidance only. Nest English is independent and not affiliated with Cambridge, IELTS, ETS/TOEFL or any official provider, and its estimate is not a certified score.

    Privacy

    Your Privacy & Your Data

    Privacy isn't an afterthought here. The self-assessment test runs entirely on your device with no account — the only part of Nest English that stores anything on a server is the optional teacher/organization account system, explained below.

    Teacher & organization accounts are the exception

    If you create a teacher or organization account, that's a real account: we store your name, email, a securely hashed password, and the classes/assignments you create, so your workspace is available across your devices. Quick Classroom (no sign-up) stays fully local-first for students. Full detail is in our Privacy Policy.

    Everything stays on your device

    There is no backend. Your answers, score and report are generated locally and never leave your browser.

    No account for the test itself

    No email, no sign-up, no login needed for the self-assessment test. You can take it without identifying yourself. (Teacher/organization tools are opt-in and do use an account — see below.)

    No tracking, no ads

    No analytics, no third-party trackers, nothing sold to anyone. There are no ads in this tool.

    Your voice — the honest version

    We never record, store or upload your audio. But in Chrome and Edge the browser's own speech engine uploads your recording to Google to turn it into text. That is the browser doing it, not us — and we would rather tell you than hide it. You can skip the speaking module entirely.

    AI features (third-party)

    Off

    Turning this off means puter.js is never even downloaded. Turning it on lets Professor Hoot and the AI feedback work — and sends what you write to Puter.

    What is saved locally

    Your XP, streak, test history, flashcard progress and settings are kept in this browser's local storage so your progress survives between visits. Clearing your browser data — or using the button below — removes all of it permanently. Export a backup first if you want to keep it.

    Review

    Review Your Mistakes

    Every question you missed is saved here so you can learn from it. Stored only on this device.

    Interactive Stories

    Choose a Story

    Read, choose what to say, and watch the story change. Professor Hoot explains why some replies sound more natural.

    Shadowing Lab

    Listen, Then Say It

    Pick an idiom, listen to it, then read the sentence aloud. We compare your words to the target — all in your browser.
