Studying smarter with AI has almost nothing to do with getting answers faster. It is about closing the gap between "I read the explanation" and "I could do this on a test." The tool that gets you there is the one you can talk to for more than one message, and the main way you use Lensia is exactly that: a sidebar chat that opens next to your study page in Chrome and stays there while you work a topic out. You ask, it explains, you push back, it goes deeper. When a single line in a reading trips you up, a floating panel grabs it off the screen in a couple of seconds so you never lose your place. This post is a routine for using both to actually learn the material, not just move past it. Install Lensia free to follow along.
Lensia is a study aid. The routine below assumes you are using it on practice problems, your own notes, and review material, and checking your work after you have tried it yourself. Using any AI during a graded assessment where it is restricted is academic dishonesty, so this is about the hours before the test, not during it.
Why "ask once, move on" is the trap
The fastest way to feel like you studied without actually learning anything is to paste a question into a chat tab, skim the answer, nod, and move to the next one. You retained the shape of the answer, not the method, and the method is what the test asks for. Studying smarter means turning every explanation into something you can reproduce on your own.
That takes a back-and-forth, which is why the sidebar matters more than a one-shot answer. You are not collecting answers. You are building the ability to get them yourself.
Set up the sidebar as your study desk
Open the sidebar chat from the Lensia icon in your Chrome toolbar. It docks into Chrome's side panel next to your material, and it is on every plan. Three things make it a study desk rather than a search box:
- Conversation history stays between sessions, so a topic you worked through on Monday is still there Thursday night when it finally matters.
- Bookmarks hold the explanations you know you will reread before the exam, so they are not lost in the scrollback.
- A model picker lets you start easy questions on a fast model and switch to a stronger one, like Claude Sonnet 5, the moment a proof or a derivation needs slower reasoning.

A study loop that actually sticks
Here is the loop I would build a session around. It works whether you open the sidebar or grab a question with the panel.
- Try it cold first. Attempt the problem with no help. The struggle is where the learning happens, and it also shows you exactly what you do not know yet.
- Ask, do not copy. Open the sidebar and paste the problem, or capture it with the panel. Read the walkthrough once.
- Push back. Type "why does step two work?" or "what would change if the sign flipped?" This is the part most people skip, and it is the part that teaches.
- Reproduce it. Close the explanation and redo the problem from scratch. If you can get there without looking, you own it. If you cannot, you found the gap, so ask again.
Do that four-step loop on ten problems and you will learn more than you would skimming fifty answers.
Turn your notes into practice
The single best trick for studying smarter is to stop rereading and start testing yourself. Paste a chunk of your notes or a chapter summary into the sidebar and ask it to write practice questions from that material. Attempt them cold, then paste your answers back and ask where you went wrong. You have turned passive reading into active recall, which is the thing memory research actually rewards. For subject-specific angles on this, the complete AI homework helper guide breaks it down by class.
For multiple choice specifically, include every answer option when you ask, so the AI explains why one holds and the others fail. That comparison is the reasoning you want to internalize. There is a whole method for this in AI for multiple-choice practice.
Use the panel for speed, the sidebar for depth
The floating panel is for the moments a full conversation would be overkill. You are reading, one sentence stops you, and you want it explained without breaking stride. Press Ctrl+Shift+X, drag a box around it, and the explanation floats up on top of the page in about three seconds. Ctrl+Shift+F repeats your last capture area with one keypress, which is perfect for a page of similar problems. Flip on Ask Mode and the panel becomes a typing box where you can write your own question and attach up to three images, handy for comparing two figures.
The rule of thumb: if the question is "what does this mean," the panel is faster. If the question is "help me understand this well enough to redo it," open the sidebar.
Tune the AI to the work
A few settings make the explanations fit how you study:
- Reasoning mode is a single on/off toggle that tells the AI to slow down and check its work. Leave it off for recall and definitions; turn it on for multi-step math and logic.
- Custom Instructions save a nickname, a preferred explanation style, and a note about what you are studying, so answers come back in a voice that actually helps you.
- Web search and fetch URL let the sidebar pull a formula or source off the live web while it explains.
- Agent mode on Pro lets the sidebar chain steps: read your open lecture notes, take a fresh screenshot, look something up, then answer.
- Lensia Max is the auto-router: leave the model on it and Lensia picks a fitting model per question and takes 15 percent off the cost.
Basic gives about 10x the Free usage and covers a full semester of studying. Pro has the highest usage allowance and agent mode. You sign in with Google to activate.
Build the habit this week
Pick one class, install Lensia, and run the four-step loop on your next problem set. Open the sidebar for the concepts you want to actually understand, and keep the panel handy for the quick "what does this mean" moments while you read. Do it for a week and studying stops feeling like rereading and starts feeling like practice.
Install Lensia from the Chrome Web Store and study your next topic the way you will be tested on it.
