Dedicated writing module with CELPIP-style writing prompts, plus AI-assisted feedback.

Curated vocabulary

Know the exam

Every part of the CELPIP — and how to beat it

Pick a skill, then open any part: what it actually tests, the trap most candidates fall into, the guide, and somewhere to practise it.

Four passages that get progressively less literal. Time runs out in Part 4, so the budget you set in Part 1 decides your band.

Try it before you sign up

Start a real practice run of this section — no card, no account to begin.

1

Part 1 — Correspondence

≈11 min · 11 questions

Reading a personal letter, then completing a reply to it.

The trap

The second half is filled from the reply’s logic, not the letter’s wording. Candidates who keep re-scanning the letter lose the time they need for Part 4.

Read the guide
2

Part 2 — Diagram

≈9 min · 8 questions

Matching a message against a diagram, floor plan or schedule.

The trap

Two options usually fit the picture. Only one fits what the message actually asks for — read the request again before choosing.

Read the guide
3

Part 3 — Information

≈10 min · 9 questions

Scanning a factual passage split into labelled paragraphs and placing each statement.

The trap

"Not given" is a real answer and it is deliberately uncomfortable. If the passage does not say it, do not reason your way there.

Read the guide
4

Part 4 — Viewpoints

≈13 min · 10 questions

An opinion article plus a reader’s comment responding to it.

The trap

Half the questions are about the comment, not the article — and this is exactly where the clock runs out. Bank time in Parts 1–3.

Read the guide

Every part above is in the free practice bank.

No sign-up for Reading. Instant CLB estimate.

How it works

Three steps. The whole loop in under a minute.

Capture once. Review on autopilot. Use the words in real life. FlexiLingo is built around the content you already consume — not another textbook to slog through.

01

Capture

Click any word in a YouTube subtitle, in a podcast transcript, on a webpage, or in a photo from your phone. FlexiLingo grabs the translation, the sentence context, and the difficulty level (CEFR A1–C2).

YouTube · podcasts · webpages · photos
02

Review

Saved words land in your deck and surface again at the perfect interval. Pick the spaced-repetition algorithm that fits you — Leitner, SM-2, or FSRS — none of that one-size-fits-all stuff.

Leitner · SM-2 · FSRS
03

Apply

Practice typing, hear native pronunciation, and rehearse the words in context. Decks follow you on browser, phone, and desktop, so the next time you see the word in the wild, you know it.

Real platforms, real content

Click any platform to open a sample — these open in a new tab, and everything you save syncs to your decks on iOS and the web.

What sets FlexiLingo apart

Built around how people actually learn languages.

Not gamified beginner content. Tools for people who already consume foreign-language media and want to grow — with real interactive subtitles, CEFR tracking, and review modes that push active recall.

Interactive Subtitles

Click any word. Hear Lena. Save to your deck.

Our podcast player is interactive on every surface. Words are CEFR-tagged in real time, and Lena is a message away for grammar or translation help.
