Brilliant vs Preply
A side-by-side editorial comparison of Brilliant and Preply — release velocity, themes, recent moves, and the top alternatives to consider.
Brilliant vs Preply: at a glance
What is Brilliant?
Brilliant launches Koji, a graphical AI tutor — its first product move in 15 months.
Brilliant ships infrequent, essay-style blog posts that read as much like product manifestos as changelog. The most recent post announces Koji, framed as a graphical AI tutor — the first new headline product in this ten-entry window. The rest of the timeline is course-design philosophy around algebra, programming, and learning-game evals.
What is Preply?
Preply is running a templated long-tail SEO content engine, scaling niche-language guides far faster than features.
Preply's recent feed is content, not product releases — a high-cadence blog operation. The last 30 days split between consumer-facing niche-language guides (business vocabulary for Vietnamese, Kazakh, Urdu, Armenian, and Basque, plus an Uzbek alphabet primer) and an earlier B2B L&D cluster on hybrid programmes, microlearning, and retention economics. The same-day batch of five near-identical 'business vocabulary' posts points to a templated, programmatic content pipeline aimed at search demand.

Brilliant
3.8EDTECH
Brilliant launches Koji, a graphical AI tutor — its first product move in 15 months.
◆ Current state
Brilliant ships infrequent, essay-style blog posts that read as much like product manifestos as changelog. The most recent post announces Koji, framed as a graphical AI tutor — the first new headline product in this ten-entry window. The rest of the timeline is course-design philosophy around algebra, programming, and learning-game evals.
◆ Where it's heading
The throughline across these posts is the same: lean on visual, game-like interaction and use AI to scale the tutor-style feedback loop the team keeps writing about. Koji is the first concrete productization of that thesis after a long stretch of essays describing the approach. Cadence remains slow, which suggests Brilliant publishes only when something is meaningfully different.
◆ Prediction
Expect Koji to roll out across more subjects following the same algebra-then-CS pattern earlier posts described, and for future entries to attach Koji-specific course launches rather than announce new products from scratch.
Preply
5.0EDTECH
Preply is running a templated long-tail SEO content engine, scaling niche-language guides far faster than features.
◆ Current state
Preply's recent feed is content, not product releases — a high-cadence blog operation. The last 30 days split between consumer-facing niche-language guides (business vocabulary for Vietnamese, Kazakh, Urdu, Armenian, and Basque, plus an Uzbek alphabet primer) and an earlier B2B L&D cluster on hybrid programmes, microlearning, and retention economics. The same-day batch of five near-identical 'business vocabulary' posts points to a templated, programmatic content pipeline aimed at search demand.
◆ Where it's heading
The center of gravity is breadth of language coverage as an SEO moat — capturing professional-learner search in under-served languages where competitors have thin content. In parallel, the L&D pieces position Preply Business for corporate buyers, framing language training as a retention lever rather than a perk. These read as two distinct funnels: consumer long-tail acquisition and enterprise demand generation.
◆ Prediction
Expect the templated business-vocabulary series to keep rolling out across more niche languages, with the B2B thread deepening via additional L&D and ROI framing aimed at corporate buyers.
