Brilliant vs Opencast
A side-by-side editorial comparison of Brilliant and Opencast — release velocity, themes, recent moves, and the top alternatives to consider.
Brilliant vs Opencast: 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 Opencast?
Opencast maintains three release lines in parallel, and its feed shows only version numbers.
Opencast, the university lecture-capture platform, ships regular point releases on three supported lines: 20.x (current), 19.x and 18.x. Every feed entry is a version tag that links to external release notes, so the specific changes are not visible here. The steady pattern of 20.x and 19.x releases landing within a day of each other points to coordinated backporting.

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.
Opencast
2.5EDTECH
Opencast maintains three release lines in parallel, and its feed shows only version numbers.
◆ Current state
Opencast, the university lecture-capture platform, ships regular point releases on three supported lines: 20.x (current), 19.x and 18.x. Every feed entry is a version tag that links to external release notes, so the specific changes are not visible here. The steady pattern of 20.x and 19.x releases landing within a day of each other points to coordinated backporting.
◆ Where it's heading
The cadence is roughly monthly per line, with 18.x releases getting rarer, which fits a project that supports older majors for a set window and then retires them. Because the feed has no changelog content, it doesn't show which features are moving.
◆ Prediction
Expect 20.5 and 19.10 around late October and 18.x to wind down; what they will contain can't be read from this feed.
