DrillKit is an AI-powered tool that turns your online lesson chat from Zoom, Google Meet, Skype, or Microsoft Teams into professional, print-ready ESL worksheets in under 30 seconds. It automatically extracts vocabulary, generates exercises (gap-fill, error correction, vocab match, word formation, and more), and produces beautiful PDFs tailored to the student's CEFR level and native language.

Does DrillKit support Zoom chats?

Yes! Simply copy the chat text from your Zoom, Google Meet, Skype, or Microsoft Teams lesson and paste it directly into the input area. You can also paste vocabulary lists or handwritten notes. DrillKit's AI strips out timestamps, sender names, and other noise automatically.

Can I export worksheets to PDF?

Absolutely. Every worksheet is generated as a high-quality, print-ready PDF. Pro users can also export to Google Docs and customize branding with their school logo and accent colors.

Which languages are supported?

DrillKit supports translations in 11 languages: Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese, Arabic, Turkish, and Russian. The AI auto-detects the student's native language from the chat transcript.

What exercise types can DrillKit generate?

DrillKit generates 11 exercise types: Gap Fill, Vocab Match, Error Correction, Sentence Completion, Multiple Choice, Word Scramble, Sentence Reorder, Translation, Word Formation (Cambridge Part 3), Key Word Transformation (Cambridge Part 4), and Dialogue Builder.

How does the AI extract vocabulary from chat transcripts?

The AI scans your pasted chat transcript, strips out noise (timestamps, reactions, media placeholders), identifies teachable vocabulary, phrasal verbs, idioms, and student errors, then scores each item by relevance. You review and select the best items before generating exercises.

Is DrillKit free to use?

Yes! The free plan includes 10 worksheets per month with 4 exercise types and standard templates. The Pro plan ($4.99/month or $3.33/month billed yearly) unlocks unlimited worksheets, all 11 exercise types, custom branding, and priority AI processing.

Can I customize the worksheet with my school branding?

Pro users can add their school or institution name, choose custom accent colors, select from 5 worksheet styles (Standard, Classic, Modern, Playful, Academic), and add footer text to every generated worksheet.

The Problem with Most Gap-Fills

Gap-fill exercises are the bread and butter of ESL worksheets. But most of them are fundamentally broken.

Consider this common example:

"The restaurant was very _____." (crowded / busy / noisy / expensive)

All four options could be correct. The student isn't being tested on vocabulary — they're being tested on mind-reading. Which word did the teacher want?

Good gap-fill exercises have one rule above all: the blank must be unambiguous. Only one answer should be defensible from the context.

The 5 Rules of Effective Gap-Fills

Rule 1: One defensible answer only
Bad: "The restaurant was very _____." (could be anything)
Good: "The restaurant was so _____ that we couldn't find a single empty table." (only "crowded" works)

Rule 2: Position blanks mid-sentence
Starting a sentence with a blank gives zero context. Place the blank where surrounding words constrain the answer.

Rule 3: Match CEFR level precisely
A1 sentence: "I _____ coffee every morning." (like)
C1 sentence: "Had it not been for the _____ discussion, I might never have reconsidered." (enlightening)

Rule 4: Plausible distractors only
All four options should be the same part of speech, similar difficulty, and genuinely tempting. "Car / Banana / Democracy / Dog" isn't testing vocabulary — it's testing common sense.

Rule 5: Test different words in each item
Don't use the same target word three times. Each item should test a different vocabulary word from the lesson.

CEFR-Calibrated Examples

🟢

A1-A2

"She _____ to the store yesterday." → went (5-8 word sentences, present/past simple)

🟡

B1-B2

"If I had more time, I would _____ take up a hobby." → definitely (conditionals, phrasal verbs)

🔴

C1-C2

"The _____ of the proposal left everyone speechless." → audacity (sophisticated collocations)

lightbulb

Teacher Tip

"When creating gap-fills manually, try the "cover test": cover the answer and read the sentence. If you can think of 3+ words that fit, the sentence needs more context. If only one word naturally fits, you've got a winner."

How DrillKit Solves This Automatically

DrillKit's AI is specifically trained to follow the unambiguity rule. Every generated gap-fill sentence is designed so that only one answer is defensible from context.

The AI also calibrates difficulty to CEFR levels — A1 sentences use 5-8 words with present simple, while C1 sentences employ inversion, sophisticated collocations, and nuanced vocabulary. Distractors are always the same CEFR band as the correct answer.

This is what separates a purpose-built worksheet generator from a generic AI chat — pedagogical awareness baked into every exercise.

Frequently Asked Questions

How many options should a gap-fill have?

add

Four options is the gold standard. Three is too easy (33% chance of guessing), five is overwhelming. Four options with plausible distractors creates the right challenge level.

Should gap-fills always have multiple choice?

add

Not necessarily. Open gap-fills (no word bank) are harder and better for testing production. Multiple-choice gap-fills test recognition. Use open fills for B2+ students who need to produce language, and multiple choice for A1-B1 who are building recognition.

Can DrillKit generate gap-fills for phrasal verbs?

add

Yes! Phrasal verbs get a wider blank (__________ instead of _____) and the AI ensures the sentence context makes only one phrasal verb possible.
