How it works

Three taps from open to fluent.

01

Swipe the feed.

Vertical, TikTok-style. Each card is a short bilingual lesson — English line, your native language below, with AI narration and ambient music carrying it.

02

Read along.

Lines fade in to the narration. Atmospheric AI artwork sets the mood — calm, hopeful, reflective, or melancholic — auto-matched to the lesson.

03

Speak when ready.

Tap the mic, read the script. Whisper transcribes; Gemini scores accuracy, fluency, pronunciation, and pace — and tells you what to fix, in your own language.

Languages we speak

English paired with 12 languages — your own, on every line.

Pick your first language to read alongside English. Spikdi translates, narrates, and scores you in your own words.

More language pairs rolling out for Super members.

AI lesson generation

One line of thought → a finished bilingual lesson.

Type any theme — heartbreak, Monday energy, the smell of rain. Spikdi writes the bilingual script, paints a portrait background, picks the music, and narrates it. About 90 seconds end to end.

Choosing mood & music
01

Write the script

Gemini 2.5 Flash drafts a short bilingual passage at the reading level you choose (L1–L5, CEFR-mapped).

02

Paint the art

Imagen 4 generates a portrait-orientation background that matches the lesson’s mood. Re-roll up to 4 takes.

03

Score the music

A curated Freesound library picks ambient music to match — and a TTS narrator reads the lesson line by line.

Voice practice & scoring

Read out loud. Get four numbers back.

A full-screen teleprompter walks you line by line. A live waveform shows your voice. When you finish, Whisper transcribes and Gemini grades you across four metrics — then writes one coaching tip in your native language.

01 · Read out loud

A teleprompter that focuses where you are.

The current line is sharp. Past lines blur out. A live gold waveform shows your voice. Tap any line to rescan. 3-second pre-roll before recording.

  • 3s countdown pre-roll
  • Live mic waveform
  • Tap-to-rescan lines
  • Pause & resume
02 · Read your scorecard

Four numbers, four colors, one coaching tip.

Whisper transcribes; Gemini grades. Every sentence gets a color-coded score and the transcript of what we actually heard. Improvement deltas next to every metric.

Accuracy

Did you read the words correctly?

Fluency

Did it flow, or did you stall?

Pronunciation

How close to a native speaker?

Pace

Steady, rushed, or dragging?

One coaching tip, written in your first language, after every attempt.

Up here, the words come slower.

I think that is fine.

I have time. The mountain has time.

For creators

A studio in your pocket.

Spikdi is a creator platform, not a textbook. Anyone can publish — students, writers, teachers, native speakers learning your language. Your lessons reach the For You feed.

Two creation paths

Generate from a prompt with AI, or write a bilingual script yourself. Both publish to the same global feed.

Music & mood controls

Swap the ambient track, trim its start and end, re-roll the AI art, retune the mood — all before publishing.

Real engagement metrics

Followers, total views, total likes, top voice attempts on your lessons, current and longest streak.

Drafts that wait for you

Generation auto-saves as a draft. Come back, edit the music, swap the image, hit Publish when it’s right.

Voices

What real learners say.

It doesn't make me feel dumb. That's a first for an English app.

Nó không khiến tôi cảm thấy ngu. Đó là điều lần đầu tôi gặp ở một app tiếng Anh.

I open it instead of Reels before bed. The reading sticks more than I expected.

Calm. I needed an English thing that was calm. This is the first.

Calmo. Eu precisava de algo de inglês que fosse calmo. Este é o primeiro.

Having my own language next to English means I can finally read at the end of a long day.

내 모국어가 영어 옆에 있다는 건 긴 하루 끝에 드디어 읽을 수 있다는 뜻이에요.
