A short, honest description of who each tier is built for — and who probably doesn't need to upgrade yet.
For curious beginners, casual learners, and anyone wanting to test the waters before paying for ESL software. Explorer is genuinely complete for A1-A2 work — the daily 5-crossword cap is more than enough for a 10-15 minute review session. If you're at the beginning of your English journey, Explorer can carry you for months.
For Explorer users who hit the 5-crosswords-a-day cap or who find ads breaking their flow. Plus is the cheapest "I'm taking this seriously" tier — unlimited crosswords, ad-free across the site, and a vocabulary tracking dashboard that shows which words you've seen, mastered, or still struggle with.
The recommended tier and the one most adult learners settle on. Pro unlocks B1, B2, C1, and C2 vocabulary plus spaced-repetition review (the single highest-ROI feature for long-term retention). If you have a TOEFL, IELTS, Cambridge, or university-admission goal — or you simply want to move beyond A2 — Pro is the level. Skip-level placement included.
For learners who already use other Grande Web Network sites — A2Z Word Finder for word-search help across 11 languages, A2Z Words for grammar and Wordle strategy, Letters Into Words for multilingual anagram puzzles, and 60+ other GWN properties. One login, ad-free across the empire, and the same premium experience whether you're on Llexi or a sister site.
For learners who want a 1-on-1 AI ESL tutor: personalized lesson plans tuned to your weak vocabulary clusters, weekly progress summaries that flag what to focus on next, AI conversation practice with feedback on grammar and word choice, and (where supported) pronunciation feedback. It's not a thin OpenAI wrapper — it's fine-tuned on ESL pedagogy and CEFR descriptors.
Five tiers, twelve features, one honest comparison. No marketing spin, no asterisks — what you get is what's shown.
Free Explorer and Plus tiers include A1 + A2 vocabulary only (roughly 1,500 word families). Pro, All-Access, and All-Access+AI unlock B1, B2, C1, and C2 — a full vocabulary range covering 8,000+ word families with the full CEFR descriptor set. The B1 level alone roughly doubles the vocabulary count over A2, so this is the most meaningful jump in the ladder.
Explorer caps at five crosswords per day. Plus and above are unlimited. Every Llexi crossword is filtered to its CEFR vocabulary range — an A2 crossword uses only A1-A2 vocabulary; a B2 crossword stays within B2-and-below. Clues are written as definitional prompts (not cryptic) so the crossword teaches context, not just orthography.
Pro and above include the Llexi spaced-repetition review system — vocabulary you've encountered gets scheduled for retrieval practice at expanding intervals (1 day, 3 days, 1 week, 2 weeks, 1 month, 2 months). This is the single highest-ROI premium feature for long-term retention. Plus tier sees re-encounters organically through unlimited crosswords but without the formal spaced schedule.
Explorer sees sample theme packs (food basics, greetings, numbers). Plus adds tracking but the same content scope. Pro unlocks the full theme library — academic English, business English, medical English, travel and tourism, technology and digital life, news and media, plus deep CEFR-tagged variants of each. All-Access mirrors the Pro library; All-Access+AI adds AI-generated custom themes on demand.
All-Access and All-Access+AI use the same login to access premium features on 60+ Grande Web Network sites: a2zwordfinder.com (word-finder and crossword helper across 11 languages), a2zwords.com (Word Education Hub with grammar guides, etymology, and Wordle strategy), lettersintowords.com (multilingual word maker), and the rest of the GWN linguistic-tools family. One subscription, one login, one ad-free experience across the empire.
The top tier adds an AI tutor built specifically for ESL pedagogy. It generates personalized study plans focused on your weak vocabulary clusters (drawn from real analytics data on your progress), writes weekly progress summaries that flag what to focus on next, runs AI conversation practice with feedback on grammar and word choice, and provides pronunciation feedback where browser audio supports it. Built on models fine-tuned for CEFR descriptors — not a thin OpenAI wrapper.
The questions that come up before signing up. Schema.org marked so search engines surface these as rich-result answers.
Yes. Cancel anytime from your account settings — no retention calls, no penalty, no "are you sure" maze. You keep premium access until the end of your current billing period, then you revert to the free Explorer tier with all your progress and vocabulary tracking still intact.
Yes — 14-day money-back guarantee on new subscriptions, no questions asked. If Llexi isn't the right fit, email [email protected] within 14 days of your first paid charge and we'll refund in full. After the 14-day window, you can still cancel anytime but past payments are non-refundable.
Not yet — a family plan covering up to 5 learners is on the 2026 roadmap. In the meantime, multiple Explorer (free) accounts work perfectly for households learning together; everyone gets their own progress tracking. If you need 3+ Pro accounts for a household or classroom, email [email protected] and we'll set up a manual discount.
Genuinely free, forever. Explorer is ad-supported and gives full access to A1 and A2 vocabulary lessons plus five crosswords per day. It's not a 7-day or 30-day trial — it's a permanent tier. Some learners stay on Explorer indefinitely and that's fine; we'd rather have you using Llexi than not.
Yes — annual billing saves roughly 16-17% versus paying month-to-month. For Pro: $29.99/year versus $35.88/year if you paid month-to-month. The savings increase at higher tiers; All-Access+AI annual at $49.99 saves $9.89 versus monthly billing.
CEFR is the Common European Framework of Reference for Languages — six levels from A1 (beginner) through C2 (mastery). Explorer (free) and Plus include A1 + A2 only. Pro, All-Access, and All-Access+AI unlock all six levels (A1, A2, B1, B2, C1, C2). The Pro tier is where most adult learners with intermediate-or-above ambitions land.
Real feature. All-Access+AI includes an AI tutor that generates personalized study plans (focused on your specific weak vocabulary clusters from analytics data), weekly progress summaries (what improved, what plateau-ed, recommended focus for next week), AI conversation practice (free-form dialog with grammar and word-choice feedback), and pronunciation feedback (where browser audio support allows). It's built on fine-tuned models with ESL pedagogy and CEFR descriptors baked in — not a thin OpenAI wrapper. The $4.99/mo tier is unlimited; no per-message charges.
No credit card to start. A1 vocabulary plus five crosswords a day, forever. Pick a paid tier when (and if) your goals demand it.
