TONGUE-ING
All the world’s tongues in your mouth.
A system, not another app

Every
tongue.
One system.

Most apps hand you pieces. Cards here, a podcast there, a chatbot sulking in a third tab, and none of them talk to each other. Tongue-ing is one engine built on how acquisition actually works: input you almost understand, shadowing, real production, and reviews that arrive right before your brain hits delete. Pragmatic, effective, and honest about what fluency costs.

And the goal is not to keep you in an app forever. No streaks to babysit, no gems to hoard, nothing engineered for addiction, and nobody guilt-trips you at midnight. Tonguey sleeps. The goal is proficiency, then fluency.

Hi, I’m Tonguey. Starting something is the beautiful part. I once said hello to a stranger in Naples and by Friday we co-owned a restaurant. Leave your name. Let’s start something.

It’s about being able to connect to the world and tongue all of its people.

  1. Absorb Read and listen to real material you mostly understand. That edge where you almost follow? That is where acquisition happens. Every word quietly tracks how well you know it, and grammar tags along as a plain-words explanation of what the language is doing, so you are never just matching tiles and praying.
  2. Mirror Repeat native audio out loud, sentence by sentence, the way interpreters train. Yes, out loud. Your mouth has to learn the language too, not just your eyeballs.
  3. Produce Say it, write it, roleplay it. Rehearse real scenarios with the AI conversation simulator, pitched at your level and rigged with the words you just met.
  4. Return Everything above feeds one review queue, scheduled against your forgetting curve. A few minutes a day, and the words stop leaving.

Never assemble your own curriculum again

Every serious learner knows the second job: hunting podcasts, scraping articles, building decks, duct-taping five tools into a routine. That job is over. Fresh reading and listening arrive on their own, in your language, at your level, about the things you actually find interesting. The news you would read anyway, now doing double duty. A clear path to function you never have to cobble together, because the system already did. And when you want something specific, import it yourself in under a minute: Netflix, YouTube, a news article, a PDF, an ebook, the weird forum thread you are inexplicably invested in.

Absorb through reading, listening, watching and observing

The opening line of Don Quixote, the way a learner sees it.

En un lugar de la Mancha, de cuyo nombre no quiero acordarme, no ha mucho tiempo que vivía un hidalgo de los de lanza en astillero, adarga antigua, rocín flaco y galgo corredor.

Strong gold is new. It fades as you learn a word, and disappears once you know it. Names you ignore stay grey. Tap any word for its meaning, its audio, and a one-touch flashcard.

And anything can become a lesson like this one, with no effort. Drop in a YouTube link and the video arrives synced to its text. Watch Netflix with the transcript following along. Bring a PDF, an ebook, a news article, or paste anything at all. Under a minute, every time.

Rehearse life before it happens

Real conversation practice, on demand, with a frontier AI conversation partner. This is not a chatbot reading from a script: tell it the exact scene you are walking into, set your level, and play it out. It speaks, it listens, it pushes back, it adapts mid-conversation, and it remembers the words you met on Tuesday. Rehearse the moment before life springs it on you. That is all we are saying for now.

“I want to ask the cute barista out.” “Ordering at a Tbilisi market, no English allowed.” “My in-laws are coming to dinner. Help.” “The landlord says the boiler is my fault.”

Grammar without the dread

Nobody ever fell in love with a language through a conjugation drill. Here, grammar arrives in plain words, one small piece at a time, always pinned to sentences you already know. No jargon walls, no tables to memorise before you are allowed to speak. A rule shows up exactly when it explains something you have already noticed, which is the only moment grammar is interesting.

The tongues you have accelerate the one you want

If you already speak a cousin of the language you are learning, you should not be starting from zero, and here you do not. The system knows every tongue you carry and maps the new one against them: shared roots, regular sound shifts, the grammar that transfers and the false friends that do not. Comparative lessons teach the difference, not the language from scratch. Learn one pattern and hundreds of words fall over like dominoes.

Speak Mandarin → learning Cantonese
Mandarin -ao usually lands as Cantonese -ou
高 gāo gou1 好 hǎo hou2 道 dào dou6

Same characters, systematic sound shifts. Your reading carries over almost whole; the lessons focus on retuning your ear and your tones.

Speak Spanish → learning Portuguese
Spanish -ción swaps to Portuguese -ção
nación nação canción canção tradición tradição

Thousands of words arrive on day one. The lessons spend your time on what actually differs: the nasal vowels, the false friends, the rhythm.

You’ve chosen Georgian! Since you know Turkish, you’re already at home: no gender, postpositions, and verbs built from little pieces.

A language comes with a people

The pre-built content is not filler prose about airports. It carries the history, the myths, the legends, the toasts, the songs and the jokes that native speakers actually grew up on, the pieces closest to their hearts. By the time you can hold a conversation, you will also know what the words are carrying, and why an idiom lands the way it does. Fluency that arrives without the culture is just vocabulary.

Tonguey is with you the whole way

Every learner gets Tonguey: an eccentric, lovable AI assistant who is there at every step. He queues your reviews at the right moment, explains what just went wrong in plain words, celebrates what went right, and heckles you gently when you stall. And as a tongue himself, he knows an awful lot about acquiring them.

You stopped two words short of ordering breakfast. Which reminds me of the time I shared a tortilla with Ana de Armas on a sleepy morning in Málaga. She also quit before the churros. Back at it.

I want every tongue in the world in my mouth

Most apps go quiet the moment you step past the big five, and quieter still when you ask for the accent people actually speak. Every language here gets the full system: the reading, the audio, the dictionary, the grammar, the conversations. Spanish in its real accents. Arabic dialect by dialect. Chinese as a family, not a checkbox. And where the resources are scarce, we build them ourselves.

A system built on learning science

None of this is vibes. A century of memory research and language research keeps pointing the same way, and the system is shaped around what the studies actually found. The numbers are from the papers, and everything links to its source.

The forgetting curve, and the schedule that beats it

100% 50% 0 day 1 day 3 day 7 day 16 day 30 Reviewed just in time Without review

Each gold dot is a short review, and the gaps between them grow. Ebbinghaus measured the pink curve in 1885: by his savings measure, only about a third of what he memorised survived the first day. It was replicated with modern methods in 2015. The spacing schedule is from a meta-analysis of 317 experiments: spaced review reliably beats cramming, and the best gap grows with how long you need to remember. Murre & Dros, PLOS ONE, 2015 · Cepeda et al., Psychological Bulletin, 2006

Retrieval beats re-reading

80% 36% Testing yourself Re-reading

Recall of 40 Swahili words, one week later. Every review in this system is retrieval, never re-reading. Karpicke & Roediger, Science, 2008

2 of 10 techniques hold up

Practice testing Spaced review

Of ten popular study techniques reviewed for the Association for Psychological Science, exactly two earned the top utility rating, and this system is built on both. Among the lowest rated: re-reading and highlighting, the two everyone defaults to. Dunlosky et al., PSPI, 2013

34 studies

A meta-analysis of extensive reading, 34 studies and nearly 4,000 learners, found large gains in vocabulary, comprehension and reading speed from reading a lot of material you mostly understand. That is why reading real content is the front door here, with every word tracked. Nakanishi, TESOL Quarterly, 2015

Shadowing works

Interpreter-style shadowing measurably sharpens phoneme perception, with the largest listening gains for lower-proficiency learners, which is exactly when you need it. It is the Mirror step of the method, not a party trick. Hamada, Language Teaching Research, 2016

Proficiency measures, not gems

Progress here maps to the CEFR, the shared scale that schools, employers and real certifications use to describe what you can actually do in a language. B1 here means B1 anywhere. No streak guilt, no jewellery.
