Drill
Inline reading

Ask the sentence without leaving it.

Drill turns the phrase you are stuck on into a place you can question. Select it, read the answer below it, and keep the original passage in view.

  • 01Anchored to the exact sentence
  • 02No copy-paste loop
  • 03Recursive follow-ups

Understanding should leave a trace.

The same drill thread can become a flashcard or quiz, so the concept you just unpacked is easier to revisit later.

The old way. The Drill way.

Inline explanations make reading feel continuous again.

Without Drill

  • Copy the sentence into a chatbot and switch away from the article.
  • Open search results that answer a different version of your question.
  • Lose the exact paragraph that made the concept confusing.
  • Let follow-up questions scatter across tabs and chat history.

With Drill

  • Select the phrase that blocks you and read the answer below it.
  • Drill into any part of the explanation while parent context travels with you.
  • Zoom back to the full passage whenever you need orientation.
  • Turn a moment of confusion into a saved reading thread.

How it works

From confusion to clarity in three moves.

  1. 01

    Select the line

    Highlight the sentence, phrase, formula, or term that made the paragraph stop making sense.

  2. 02

    Read in place

    Drill opens the explanation under the exact selection, so your eyes do not leave the source text.

  3. 03

    Keep drilling

    Need another layer? Drill inside the answer and follow the idea down until it clicks.

01C.01 Anchor

The answer belongs to the sentence.

A detached chat window makes you translate the answer back into the passage. Drill keeps the answer attached to the selection that created the question.

  • 01Ideal for definitions, dense claims, equations, footnotes, and unfamiliar terminology.
  • 02The source paragraph stays visible while the explanation expands below it.
  • 03Close the drill and the page returns to a clean reading surface.
02C.02 Depth

Every explanation can become the next question.

Reading rarely fails in one layer. Drill lets you recursively ask about the explanation itself without starting a new prompt or losing the parent context.

  • 01Follow background concepts without abandoning the original passage.
  • 02Keep side branches attached to the topic they came from.
  • 03Stop at the level where the idea finally feels obvious.
03C.03 Recall

A reading thread becomes something you can revisit.

The point is not just to get an answer. It is to create a visible path from the text that confused you to the explanation that made it clear.

  • 01Useful threads become saved knowledge trees instead of disposable chats.
  • 02Review the original selection, the answer, and the follow-up branches together.
  • 03Return to the same learning path when the topic comes back later.

FAQ

Frequently asked

What does “highlight text and explain with AI” mean?+

It means you select the exact sentence or phrase that confused you, and Drill places an AI explanation directly under that selection instead of sending you to a separate chat window.

How is this different from pasting text into ChatGPT?+

ChatGPT is a separate conversation. Drill is a reading workspace: the explanation stays anchored to the original passage, and each follow-up keeps the parent context.

Can I drill into the explanation itself?+

Yes. Every answer can become a new layer, so you can ask about the unfamiliar term inside the explanation without restarting your reading session.

What content works best?+

Drill works best on dense articles, technical docs, research papers, notes, specs, and any text where a small confusing phrase blocks the larger idea.

Does the answer replace the original text?+

No. The original text stays in place. The answer opens inline under the selection and can be collapsed when you want the clean passage back.

Start reading inside the answer

Paste a paragraph, highlight the hard part, and drill until it clicks.

Drill is built for readers who want explanations without losing the page, the thread, or the reason they were reading in the first place.
