Step 1: Create Your Account and Get Your Starter Deck
Two minutes. Any device.
When you sign up, LinguaFit asks about your current Spanish level and your goals. Answer honestly since this sets your starting vocabulary and the baseline everything builds from.
Your starter Word Deck appears in your LinguaVault immediately. These are high-frequency Spanish words calibrated to your level, serving as the foundation your vocabulary will build from.
Not sure what level to select? Pick the one that feels slightly too easy. Your first Proficiency Assessment after your first session will tell you exactly where you are.
Step 2: Install the LinguaFit Sidekick
Desktop only. Takes 60 seconds.
Download the Sidekick, add it to Chrome, and pin it to your toolbar. That's the entire setup. The Sidekick activates on any webpage you choose: you don't configure anything in advance.
The Sidekick is built specifically for laptop and desktop environments. The LinguaVault works everywhere, including mobile, so you can review anywhere.
Step 3 — Your First LinguaVault Session
15–20 minutes. Any device. Start here.
Open your LinguaVault and work through your starter deck. This is where LinguaFit differs from every app you've used before: there are no multiple-choice questions. You produce every answer from scratch, with no options and no hints. Some items are phrases, not just single words, and you can answer by typing or by speaking into your mic.
It will feel harder than other apps. That difficulty is not a bug; it is the science working. The act of struggling to retrieve a word is what makes it stick.
When you practice phrases out loud, the Vault grades your pronunciation syllable by syllable, so you can see exactly which parts land and which need work. Phrase recall is also timed: a gentle nudge to stop overthinking and pull the answer up the way you'd need to in a real conversation.
After your review session, hit Quiz Me. LinguaFit generates a short story using the specific words you just reviewed, at your proficiency level, then asks you comprehension questions about it. Read the story. Answer the questions. This is active retrieval in real context, making it the most effective practice session you can have.
Step 4: Your First Sidekick Session
20–30 minutes. Desktop. Read something you actually want to read.
Open Chrome and navigate to any English article, blog post, or news piece you'd genuinely read anyway. Your favorite sports site, a tech blog you follow, or a news source you trust. The topic doesn't matter: what matters is that you care about the content.
Click the LinguaFit Sidekick icon in your toolbar. The Sidekick immediately transforms the page, converting the English text into Spanish calibrated precisely to your current proficiency level. The engine automatically weaves words from your Vault directly into the text, turning your everyday reading into a targeted practice session. Each paragraph is labeled by difficulty, allowing you to see at a glance which passages are comfortable and which are stretching you.
Read the Spanish, and use the English side whenever you need it. It’s there so you can keep moving instead of stalling or getting frustrated.
To save a word, click it and choose Add to deck. It goes straight to your LinguaVault, with no copying or app-switching. (Look up meaning is there too, if you just want a quick definition.)
At the end of each paragraph, the Sidekick deploys a comprehension quiz about what you just read. Answer it: this is the moment passive reading becomes active learning.
Step 5 — Check Your Proficiency Assessment
After your first session, this is the part most people don't expect.
After each session, LinguaFit generates a Proficiency Assessment.
You'll see your current CEFR level: the international standard for language proficiency, running from A1 (complete beginner) to C2 (near-native). You'll see your GSL score, along with a detailed analysis of your specific performance: what you know solidly, what's still fragile, and what's actively being acquired.
Most people are surprised by this. It isn't because it's discouraging; it's because it is specific in a way no language app has ever been before. This isn't "you completed 3 lessons." This is "here is exactly where your Spanish stands, and here is why."
Come back to it every few sessions. Watching your CEFR level and stability trend move is the clearest signal that you're progressing.
Your Retrievability score shows how much of your active vocabulary is currently accessible. Your Average Stability trend shows how your vocabulary is compounding over time. Both live in your LinguaVault dashboard.
