Flashcard apps that actually support math equations

Most flashcard apps cannot render real mathematical notation. Quizlet and Brainscape offer symbol pickers or screenshot workarounds, not typeset equations. The apps that genuinely render math are Anki and RemNote (manual LaTeX authoring), NotebookLM and Quizgecko (AI generation with LaTeX rendering), and ExamTeX (AI generation from your course materials with LaTeX end-to-end). Which one fits depends on whether you want to write cards by hand or generate them from your notes.

If you study calculus, statistics, economics, physics, or any subject where $\frac{\partial Q}{\partial P}$ means something, you have probably hit this wall: you type a formula into a flashcard app and get back a flat line of text — x^2 + 1/(n-1) — instead of $x^2 + \frac{1}{n-1}$. For one or two cards, that is an annoyance. For a 200-card semester deck, it is disqualifying: notation you cannot read cleanly is notation you cannot rehearse.

This guide goes through the major flashcard tools one by one, based on what their official documentation actually says they support. We build ExamTeX, so we have an obvious interest here — which is exactly why every claim below links to the source, including the cases where a competitor is genuinely excellent.

Why most flashcard apps fail at math

Mathematical notation is structural, not linear. A fraction has a numerator above a denominator; a definite integral $\int_0^1 x^2\,dx$ has bounds attached to the symbol; a matrix is a two-dimensional grid. Plain-text fields can only put one character after another, so apps built around plain text reach for workarounds:

• Symbol pickers — palettes for inserting characters like ∆, ², or √. Fine for $x^2$, useless for $\hat{\beta} = (X'X)^{-1}X'y$.
• Screenshots — write the equation elsewhere, screenshot it, paste the image. Works, but you cannot edit, search, or generate cards this way at any scale.
• LaTeX rendering — the actual solution. LaTeX is the notation system mathematics has used for decades; an app that renders it can display anything a textbook can.

The dividing line in the comparison below is simple: does the app render LaTeX, or not?

The comparison at a glance

App	Math rendering	How	AI generation with math
Anki	Yes	MathJax built in; native LaTeX with setup	No (manual authoring)
RemNote	Yes	KaTeX equation editor	Partial — manual authoring is the strength
NotebookLM	Yes (since late 2025)	Native LaTeX rendering	Yes, from uploaded sources
Quizgecko	Yes	LaTeX written and rendered by the AI	Yes
ExamTeX	Yes	LaTeX/KaTeX end-to-end	Yes, from uploaded course materials
Knowt	Partial	LaTeX in notes; flashcard editor offers a symbol picker	Yes, but math support in cards is limited
Quizlet	No	Math/chemistry symbol keyboards only	AI tools exist, but no rendering engine
Brainscape	No	Official advice: screenshot equations as images	No

Now the details, with sources.

Anki — the manual-authoring benchmark

Anki has supported MathJax out of the box since version 2.1 — no installation required. You wrap inline math in \(...\) and display math in \[...\], and it renders on desktop, AnkiMobile, and AnkiDroid. Chemistry students get mhchem notation included. There is also an older native-LaTeX path that produces images, but it requires a full TeX installation and is best treated as a power-user feature — we cover both routes in our Anki LaTeX setup guide.

The honest assessment: for self-authored math flashcards at zero cost, Anki is the benchmark. Its spaced repetition is best-in-class and its ecosystem is unmatched. The cost is your time — every card, and every equation on it, is typed by hand, and there is no built-in way to generate cards from your lecture notes.

RemNote — the most sophisticated math editor

RemNote deserves full credit here: it renders LaTeX through a KaTeX equation editor (type $$ and write), and it supports features no other tool matches — cloze deletions inside equations, so you can hide one term of a formula and test yourself on just that part. If you want to hand-craft a deeply structured math deck inside your notes, RemNote is arguably the strongest authoring environment available.

Its AI-generation pipeline is less mature on the math side — users are still requesting LaTeX support in AI flashcards from PDFs — so the manual path is where it shines.

NotebookLM — free and capable, with limits

Google's NotebookLM added flashcards and quizzes in 2025 and now renders LaTeX natively across chat, flashcards, and quizzes. Upload your lecture PDFs and it will generate cards with properly typeset equations, grounded in your sources, for free. That is a genuinely strong offer.

The limits sit around the edges: there is no true spaced-repetition scheduling (a mastery sort is not the same as an SM-2 review queue), cards live inside NotebookLM with no native export, and there is no printable output. As a study companion it is excellent; as a system for daily review over a semester, it is not built for that.

Quizgecko — solid LaTeX in a quiz-first tool

Quizgecko's help center confirms real LaTeX support: its AI writes math in LaTeX and renders it, and you can write LaTeX yourself. The product is oriented more toward quizzes and educator use than toward student flashcard review, but the math story is legitimate.

Knowt — good notes, limited cards

Knowt supports LaTeX in its notes editor, but for flashcards specifically the official guidance points to a math symbol picker, and direct LaTeX input in the card editor remains an open feature request on Knowt's own board. Knowt's free tier is remarkably generous — unlimited flashcards, learn mode, and spaced repetition at no cost — which makes it a fine choice for non-quantitative subjects. For a deck full of integrals, it is not there yet.

Quizlet — the biggest library, no rendering engine

Quizlet offers math and chemistry symbol keyboards in its editor — exponents, subscripts, special characters — but no LaTeX rendering. Students who need real notation paste raw LaTeX as plain text (it displays as code) or upload screenshots. Quizlet's strengths are real: the largest user-generated content library anywhere and polished study modes. But if your course lives in equations, the platform has no way to display them.

Brainscape — honest about not supporting math

Brainscape's help center says it plainly: basic expressions can be approximated with plain text and Unicode, and for anything complex you should create the equation in external software, screenshot it, and upload the image. Respect for the candor — but that workflow does not scale to a STEM course load.

ExamTeX — AI generation with LaTeX end-to-end

ExamTeX is our tool, so judge this section accordingly. The design goal: you should not have to author math cards by hand at all. You upload your course materials — lecture PDFs, slides, Word documents — and the AI generates a deck in which every formula is already typeset: $\epsilon_D = \frac{\%\Delta Q}{\%\Delta P}$ renders as notation, not as code. Cards feed an SM-2 spaced-repetition queue, and the same upload can produce a printable, LaTeX-compiled practice exam with an answer key — which, as far as we know, no other tool on this list offers.

What we will concede: if you prefer authoring every card yourself, Anki and RemNote give you more manual control. ExamTeX's generated decks are a first draft you review and edit, not a replacement for engaging with the material. And our free tier has monthly limits, where Anki is free forever.

How to choose

• You want full manual control and maximum free tooling → Anki. Budget real authoring time; see whether flashcards even fit your math course.
• You want the most powerful equation editor for hand-written cards → RemNote.
• You want free AI generation and don't need spaced repetition or export → NotebookLM.
• You want cards generated from your own course materials, with spaced repetition and a printable practice exam from the same upload → ExamTeX.
• Your subject has little notation → Knowt's free tier or Quizlet's library may serve you better than any of the math-first tools.

The bottom line

"Does it support math equations" has a checkable answer for every flashcard app, and the official documentation settles it: Anki, RemNote, NotebookLM, Quizgecko, and ExamTeX render real notation; Knowt partially; Quizlet and Brainscape do not. The second question — manual authoring or AI generation — is about your time. If you have a semester of lecture PDFs and an exam in three weeks, generating typeset cards from the materials you already have is the path that gets you reviewing today rather than typing all weekend.
