Most language platforms describe their content in adjectives: comprehensive, in-depth, expert-designed. Those words are hard to check. This is the version with numbers attached: exactly how many topics exist at each level, in each of Dioma's three languages, how those topics are split between grammar and natural fluency, and how the system decides when you're ready to move.

Who the curriculum is built for

Dioma is designed for learners who've outgrown beginner apps: roughly A2 through C1, past basic survival phrases but not yet at full professional mastery. That's the range the platform is built toward. Since Dioma is still a relatively new platform, we don't have full coverage across this range yet. We plan to continue expanding coverage across and adding languages.

Why sub-levels, not one flat label

A single "B2" hides a lot. Two learners at that label can have genuinely different gaps: one might have the subjunctive locked down but still trip on expressing irony, while the other is the reverse. Dioma splits each CEFR band into a minus and plus sub-level so the system can place you more precisely within B2, not just confirm that you're somewhere inside it, and so recalibration can move you within a level before it ever needs to move you between levels.

The actual numbers

Here's what's behind those sub-levels: 690 individually written topics across the three launch languages, broken down below.

260 total Spanish topics across 6 sub-levels (B1 minus/plus, B2 minus/plus)

196 total French topics across 4 sub-levels (B1 minus/plus, B2 minus/plus)

308 total Hebrew topics across 6 sub-levels (A2 minus/plus, B1 minus/plus, B2 minus/plus)

690 total topics across all three languages combined

Each topic isn't a single flashcard-style entry. It's a multi-page unit: a clear explanation, realistic examples and errors, and both writing and speaking exercises built specifically for that grammar point or fluency pattern.

Two kinds of topics, and why the mix shifts as you go

Every topic in the curriculum falls into one of two types. Grammar topics cover structural rules, things like the Spanish subjunctive, French passé composé auxiliary selection, or Hebrew construct-state agreement. Natural Fluency topics cover the layer above grammar: discourse markers, idiomatic phrasing, register, and the small choices that make a sentence sound native rather than merely correct.

The balance between the two shifts as levels rise. At Spanish B1 minus, grammar topics outnumber natural fluency topics by more than three to one. By B2, natural fluency topics make up more than a third of the total, and in French B2 plus, natural fluency topics actually outnumber grammar topics outright. That shift is intentional: the earlier stretch is about building structural correctness, and the later stretch is about sounding like a fluent speaker rather than a grammatically correct one.

A grammar topic (Spanish, B1 minus): "Ser vs. estar," teaching the structural rule for choosing between the two forms of "to be."

A natural fluency topic (Spanish, B1 minus): "Common discourse markers for organizing speech," teaching the connective phrases that make spoken Spanish sound organized rather than choppy.

How placement and recalibration decide what you see

Your starting point comes from a self-assessment during onboarding, mapped to Dioma's internal sub-levels and placed at a deliberately cautious point within your stated band. From there, your level isn't fixed. The system reviews your recent exercises every 3 sessions, watching for where errors cluster: an isolated slip reads differently than a pattern that keeps recurring across attempts, and consistent accuracy on a skill signals it's time to raise the difficulty specifically there. That mechanism, and the reasoning behind starting conservatively, is covered in full in our guide on how serious learners get placed at the right level. This piece is about the content structure that recalibration moves you through. That one is about the mechanism itself.

What this doesn't cover

We don't currently have reading, listening or live conversation practice built in. For reading and listening there's a broad set of tools and especially at the higher and intermediate levels, native content is super helpful in getting reading and listening practice. Specifically, that is why we didn't focus there for our initial launch. And Dioma's practice method is not meant to replace but rather supplement live conversations.

Over the long term we have a desire to expand across the skill sets and even explore bringing live conversation into the platform in some capacity. At launch our goal was to help learners get more speaking and writing practice, which is the part of intermediate and advanced learning that's really hard.

The curriculum itself was built by language educators, not generated by AI, and the delivery system, personalization, error tracking, and feedback, is a separate layer on top of that human-designed structure. That story, and how corrections are built to explain the rule rather than just flag the mistake, is covered in our guides on how the curriculum was designed and what corrections should actually look like.

Frequently asked questions

What CEFR levels does Dioma currently cover?

Spanish runs from B1 thru C1, French currently run from B1 through B2 and Hebrew runs from A2 through B2. The platform's target audience is A2 through C1 overall, and curriculum coverage continues to expand toward that full range.

How many topics are in Dioma's curriculum?

690 across Spanish, French, and Hebrew combined: 246 in Spanish, 196 in French, and 308 in Hebrew, each topic a multi-page unit with explanations, prompts, and writing and speaking exercises.

What's the difference between a grammar topic and a natural fluency topic?

Grammar topics teach structural rules, like verb conjugation or clause structure. Natural fluency topics teach the layer above grammar: discourse markers, idioms, and register choices that make language sound natural rather than merely correct. The proportion of natural fluency topics increases at higher levels.

Why does Hebrew start at A2 while Spanish and French start at B1?

Hebrew's script and root-pattern morphology add real time to the early stages of learning, so the curriculum starts at A2 to build that foundation properly before reaching B1, where Spanish and French coverage begins.
