LSAT

LSAT flashcards from your prep notes and drills

Upload a PowerScore or 7Sage chapter, paste your notes on logical reasoning question types, or drop in your list of flaw patterns and get back a deck of LSAT-style cards. Build the instant pattern recognition the test rewards instead of rereading the same chapter.

Add your LSAT material

Prep-book chapters, your LR notes, or a flaw-type list all work.

Generate pattern cards

Deckio turns question types, flaw patterns, and logical indicators into recall cards.

Drill daily before test day

Pattern recognition is built through repetition. Review with spaced repetition right up to your test date.

How to actually use it

01Build a deck of logical reasoning question types

Modern LSAT scoring leans heavily on Logical Reasoning — the section now appears twice, since Analytical Reasoning (Logic Games) was retired in 2024. Paste your notes on the LR question types (Strengthen, Weaken, Assumption, Flaw, Parallel Reasoning, Method of Reasoning, etc.) and Deckio generates cards that drill the goal and approach for each type until recognition is instant.

02Drill flaw patterns and logical indicators

A huge share of LR questions hinge on a small set of recurring flaws — correlation vs. causation, sampling errors, equivocation, circular reasoning. Paste a flaw list and Deckio makes one card per flaw: name on the front, definition and a one-line example on the back. Do the same for conditional logic indicators (if/then, only if, unless) so you read stimuli faster.

03Edit to match your weak question types

After a timed section, you will know which question types cost you points. Keep the cards for those types and prune the rest. A focused 40-60 card deck on your three weakest LR types beats a sprawling generic deck every time.

Why LSAT prep rewards pattern recall

The LSAT is not a content test — it is a reasoning test, and reasoning speed comes from recognizing patterns instantly. Knowing the eight common flaw types cold, or spotting a Strengthen question in two seconds, frees up the time you need to actually think. Flashcards are the fastest way to build that recognition.

Rereading a PowerScore chapter teaches you the patterns once; spaced repetition keeps them retrievable under timed pressure months later. The catch is that turning a prep book into a usable deck by hand is slow, and most generic LSAT decks do not match the framework your prep course taught.

Deckio closes that gap. Upload your chapter or paste your notes, get a draft deck of question-type and flaw cards in minutes, trim it to your weak spots, and review daily. You build pattern recognition without the busywork.

Who this is for

Foundations phase
Generate cards for every LR question type and flaw pattern. Review daily until you can name each on sight.
Weakness targeting
After a timed section, build a focused deck on the two or three question types that cost you the most points.
Final two weeks
Consolidate into a high-yield deck of the flaws and indicators you still misread, and review it every day before test day.

What it looks like

Input

Correlation-causation flaw: the argument concludes that one thing causes another based only on the fact that they occur together. Sampling flaw: the argument draws a general conclusion from an unrepresentative or too-small sample. Equivocation: the argument uses a key term in two different senses, making the conclusion appear to follow when it does not.

Generated cards

Correlation-causation flaw — what is it?

Concluding that A causes B based only on the fact that A and B occur together, ignoring alternate causes or reverse causation.

Sampling flaw — what is it?

Drawing a general conclusion from a sample that is too small or unrepresentative of the whole group.

Equivocation — what is it?

Using a key term in two different senses within one argument, making the conclusion seem to follow when it does not.

Generic LSAT flashcard sets cover the patterns but not in the framework your prep course taught, and building cards by hand eats into practice-test time. Deckio generates question-type and flaw cards from your own materials in minutes, so your deck matches the system you are already learning — then spaced repetition makes recognition automatic.

Questions

Does this still cover Logic Games?+

LSAC retired the Analytical Reasoning (Logic Games) section in 2024, so the test now emphasizes Logical Reasoning and Reading Comprehension. Deckio is most useful for LR question types, flaw patterns, and conditional-logic indicators — the parts where fast recall matters most.

Can flashcards really help on the LSAT?+

Yes, for the reasoning patterns. The LSAT rewards instant recognition of question types and flaws. Drilling those with spaced repetition makes you faster, which frees time to actually reason through each stimulus.

Can I generate cards from a prep book?+

Yes. Upload a PowerScore, 7Sage, or Manhattan chapter PDF, or paste your own notes, and Deckio generates question-type and flaw cards from the material.

Can I export to Anki?+

Yes. Any deck exports as an .apkg file for Anki. Export is available on Pro, Ultimate, and during the 7-day trial.

Is the free tier enough for LSAT prep?+

Free gives 100 AI credits per month — enough to trial it. Most test takers use Pro (1,500 credits/month) or the one-time Exam Cram pack (1,000 credits, $7) for full prep.

How should I phrase custom instructions for LSAT cards?+

Try 'one card per LR question type with its goal and approach' or 'one card per logical flaw with a one-line example.' Specific instructions produce sharper, more drillable cards.
