Ask StudyClock's AI Tutor Anything, Any Time of Night
StudyClock's AI tutor is two tools behind one sign-in. AI Chat is a conversation that rereads your last 20 messages each time you write. The Concept Explainer takes one topic, returns a fixed five-part explanation, and stops. A free account pays 6 credits per chat message and 8 per explanation. A Pro account pays 2 and 4.
This page covers how a chat works, the five teaching styles, and what Exam Simulator grades. It also explains how pinned documents and flashcards are priced, and what happens to your chats after you send them. You need a StudyClock account to use the tutor, and without one you reach a sign-in prompt. The numbers below were checked against the tool in October 2026. The pricing page covers billing. To start, open the AI tutor.
Two things are worth knowing before you start. A tutor reply can be wrong, so check facts and formulas against your textbook. And your chats stay on StudyClock's servers until you delete them, which the privacy section below explains.
AI Chat and Concept Explainer side by side
The two tabs share one screen, but nothing passes between them. Chat never sees an explanation you generated, and the explainer never sees a chat. The navigation menu lists the tool as "AI Tutor", and its own header reads "AI Chat & Concepts".
| AI Chat | Concept Explainer | |
|---|---|---|
| You send | A message of up to 2,000 characters | One topic or a pasted paragraph, 3 to 2,000 characters |
| Memory | The last 20 messages of that chat | None, each request stands alone |
| Reply | Free-form, in the style you pick | A fixed five-part explanation at a level you pick |
| Follow-up | Keep typing | No reply box, so open Chat to go further |
| Credits, Free / Pro | 6 / 2 per message | 8 / 4 per request |
| Kept afterward | The whole chat, in your history | Nothing, unless you press Save |
Choose Chat when you want to talk a problem through. Choose the explainer when you want one clean explanation of a term before a lecture or a test.
How a chat works
A chat starts when you send your first message, not when you open the tab. The first 80 characters of that message become the chat's title. Press Enter to send and Shift and Enter for a new line. A small counter appears as you type, and the credit figure beside the Send button changes with your plan and with pinned documents.
Each time you send, the tutor reads the 20 most recent messages stored in that chat. That is 10 exchanges, because your message and its reply count as two. Older messages stay on your screen, but the tutor no longer sees them. In a long chat, repeat any fact the answer depends on. Pinned documents, covered below, are sent every time on top of those 20.
Under each reply is a Copy reply button. A switch beside the box turns on Code mode, which gives code blocks a language label and a copy button. The Ideas button fills the box with openers such as "Quiz me on" and "What are the common mistakes with".
Your chat list shows your 30 most recently active chats, grouped as Today, Yesterday, This week, and Earlier. On a narrow screen the list opens from a Chats button. Deleting a chat asks first, then removes it and all its messages for good.
If a send fails, the credits come back, but your message disappears from the screen and the box is already empty. Copy a long message before you send it.
The Scan Notes tool has a "Chat with it" button. It drops your scanned text into the box, with "Here are my notes:" before it and "Please help me understand this." after it. The box holds 2,000 characters in all. A scan longer than about 1,950 characters must be trimmed before it will send.
The five teaching styles
You pick a style from the Style menu above the chat, and Study Buddy is the default. A style is a set of written instructions the AI receives before it reads your message. It steers the reply strongly, but it cannot promise a behavior every time.
| Style | What it is told to do | Pick it when |
|---|---|---|
| Study Buddy | Guide you with questions, keep replies under about 250 words unless you need more, and help you approach homework instead of doing it | You are learning a new topic |
| Strict Professor | Expect precise answers, give a hint only after a real attempt and a request for one, and correct errors directly | You want your reasoning challenged |
| Socratic Questioner | End every reply with a question and state no facts outright | You can find the answer with nudges |
| Exam Simulator | Quiz you only when you ask, then grade each answer | You want practice |
| ELI5 | Use the simplest words, sentences of 15 words or fewer, and everyday objects as comparisons | A topic feels too dense |
Strict Professor aims its criticism at your work, not at you, and it drops the strict tone if you push back. Socratic Questioner answers a plea for the straight answer with one more guiding question.
Exam Simulator is the only style with a grading step. Say "quiz me" or "test me" and it asks a question. After you answer, it replies Correct, Partially Correct, or Incorrect with one sentence of explanation, then offers another. Ask it an ordinary question, such as the difference between mitosis and meiosis, and it answers directly instead of starting a quiz. The grade is the AI's own judgment in the chat text. No answer key sits behind it, no score is kept, and no list of missed questions is built. For a scored paper from your own notes, use the practice exam generator.
You can switch style in the middle of a chat. The messages stay, and the next reply follows the new style. The name above older replies changes too, so it labels the whole chat and not who wrote each reply.
Whatever the style, the tutor also gets a few always-on rules. It shows the steps of a calculation and sanity-checks the size of the answer. If you name a book it does not have, such as an NCERT Class 12 Chemistry chapter, it is told to say so. It then offers general coverage of the topic. After three hostile or dismissive messages in a row, it states one calm boundary and stops offering new material until your tone changes.
Concept Explainer levels and the five parts
Type a term or paste a paragraph from your textbook, then pick a level. Simple is written for a 14-year-old with no background. Standard, the default, is pitched at a first-year university student. Advanced assumes a graduate student who wants technical depth.
Every result has the same five parts, in this order on screen:
A one-line summary of under 30 words, shown first under the label "In one line".
A plain explanation of 3 to 5 sentences.
One analogy built from something familiar, such as food or sport.
Three named, concrete examples.
One to three common misconceptions, each paired with a correction.
Copy all puts the result on your clipboard, with the one-liner labeled "Feynman Summary" at the end. Save stores it as a concept note in your AI Notes Library and uses one saved-item slot. Clear, or a new request, replaces what is on screen. Nothing is stored unless you press Save.
Checking your own explanation
The Concept Explainer only produces explanations. It has no box for yours. To test your own, first write the explanation from memory with your notes closed. Then paste it into a Chat message and ask which parts are wrong or missing.
The answer is an ordinary chat reply, not a score, and it is only as sharp as your request. Strict Professor is told to correct errors directly, so it suits this job. Socratic Questioner will answer with questions instead. The Feynman Technique guide lays out the method and where it came from.
Pinned documents in a chat
A pinned document is a block of your own text that rides along with every message in one chat. Open the Context button, choose Attach a document, give it a name of up to 80 characters, and paste up to 4,000 characters of text. You can pin three.
The text is sent with each message, so you never paste it again. A long chat does not push it out of the 20-message window. Pinning adds a flat 2 credits per message, whether you pin one document or three. Remove them all and the normal rate returns. Documents belong to the chat they were pinned in. A new chat starts with none, and reopening an old chat brings its documents back. There is no file upload, only pasted text.
Flashcards from a chat
The Flashcards button turns on once the chat holds four messages: two from you and two replies. Each run costs 5 credits, the same on Free and Pro. The tool reads the whole chat, not only the last 20 messages. It asks the AI for 5 to 10 cards, each with a back under 80 words, as question-and-answer, definition, or fill-in-the-blank cards.
You can type a deck title, or the deck takes its name from the chat. The cards go straight into your AI Notes Library with no preview, so read them there. For a deck built from pasted notes instead, see the AI flashcard generator.
Library space matters here. A free account holds 20 saved items across all AI tools. This step checks for a free slot only after the cards are made and the 5 credits are taken. Nothing returns the credits if the library is full. At 20 items you would see a general error message and no deck, so free a slot before you press the button.
Credit costs on Free and Pro
| Action | Free | Pro ($4.99 a month) |
|---|---|---|
| One chat message | 6 | 2 |
| One chat message with a pinned document | 8 | 4 |
| One Concept Explainer request, any level | 8 | 4 |
| Flashcards from a chat | 5 | 5 |
| Saving a chat or a concept note | 0 | 0 |
Signup puts 50 credits in a new account. On the 1st of each month, 10 credits are added to a free balance and 400 to a Pro balance. The top-up stops at 60 for Free and 600 for Pro. Credit packs cost $1.99 for 150 credits, $3.99 for 400, and $7.99 for 900. Your monthly credits are spent first, and a pack covers what is left. If the AI fails to answer, the credits for that request are returned automatically.
The chat cost beside the Send button is correct for your plan. The Concept Explainer is different. Its label and the Explain concept button show 8 credits for every account, Pro included. A Pro request is charged 4, but the button stays off until your balance reaches 8, so a Pro account holding 4 to 7 credits cannot run it.
Pro changes the AI behind the chat. Chat replies come from a Google Gemini model on both plans. On Pro, Strict Professor, Exam Simulator, and any message the system reads as a calculation go to a stronger Gemini model. A free account always gets the standard one. The Concept Explainer and the flashcard step use an OpenAI model on both plans. Everything else, including the five styles and pinned documents, is the same on both plans.
Worked example: one concept in 25 credits
It is the night before a Class 12 chemistry unit test, and Le Chatelier's principle will not stick. You have a free account with its 50 signup credits.
- In the Concept Explainer, you enter "Le Chatelier's principle" at Standard level. That costs 8 credits and leaves 42.
- Say the analogy does not explain why adding product shifts your reaction backward. You open Chat in Study Buddy style and write two messages, one describing the reaction and one asking why. That is 12 credits, 30 left, and the chat now holds four messages.
- You press Flashcards. The 5 credits leave 25, and a deck of 5 to 10 cards waits in your library.
A Pro account would pay 4, 4, and 5 for the same session, 13 in all. If you then switch to Exam Simulator and ask for a quiz, one graded question takes two messages, so 12 credits on a free account. For a whole set of questions the practice exam generator costs less, at 8 credits per 5 questions on a free plan.
Privacy, stored chats, and limits
Every message you send and every reply is saved with the chat, along with its pinned documents, until you delete the chat. A transcript you saved to your AI Notes Library is a separate copy and stays. Other users cannot see your chats. StudyClock administrators can open stored chats from an admin panel, where each chat is listed under its account.
To write a reply, your messages go to an AI provider. Chat uses Google, with OpenAI as the backup if Google is unavailable. The Concept Explainer and the flashcard step use OpenAI. The Privacy Policy lists the AI providers StudyClock uses. The Terms of Use apply to the tool.
Each message is also checked for three things: signs of real distress, a calculation, and a question about StudyClock itself. When a check matches, StudyClock stores that message's first 500 characters for review. A distress match does not change the reply. A question about StudyClock makes the tutor answer only from a StudyClock reference document, so use the pricing page for billing details. On Pro, a calculation match sends the message to the stronger model.
A few limits are plain. The tutor can be wrong, and the always-on rules lower that risk without removing it. It is a study tool, not a counselor or a doctor. If you are in real distress, talk to someone you trust or a local helpline. It also cannot know your school's rules on AI help, so follow them. Use the tutor to understand a topic, then do your own graded work.
Who the AI tutor suits
It suits students who study without a teacher on hand, such as late-night revision in a hostel or a PG room. It suits anyone who understands a topic only after hearing it in three different ways. It also suits students who learn by answering, because Exam Simulator gives recall practice before a test.
It fits less well if you need a scored paper, an answer key, or a long document read in one go. A message holds 2,000 characters and a chat holds three pinned documents of 4,000 each. Open-book or closed-book rules in a real exam are yours to follow.
A cheap first step is one Concept Explainer request on a topic from tonight's reading. On a free account that is 8 of your 50 signup credits, and you will see at once whether the five-part format suits you.
Frequently Asked Questions
Not as a built-in feature. The Concept Explainer has no box for your explanation. If you paste it into Chat and ask what is wrong or missing, you get an ordinary chat reply. Exam Simulator grades your answers to its own practice questions.
The 20 most recent in that chat, which is 10 exchanges. Older messages stay on your screen, but the tutor no longer reads them. Pinned documents are sent every time, apart from those 20.
Exam Simulator. It answers normally until you ask to be tested. After you say "quiz me", it asks a question and grades your answer as Correct, Partially Correct, or Incorrect.
The pinned text is sent to the AI along with each message, not once. The extra charge is a flat 2 per message, whether one document is pinned or three.
Yes, once the chat holds four messages. The charge is 5 credits for Free and Pro alike. A free account needs an open slot among its 20 saved items first, and the deck lands in your AI Notes Library.
Signup gives 50, once. After that a free account receives 10 on the 1st of each month until its balance reaches 60. Pro costs $4.99 a month and receives 400 on the 1st, until the balance reaches 600.
Other users cannot. StudyClock administrators can open stored chats in an admin panel. Deleting a chat from your list removes its messages.
The label is the same for every account. A Pro request is charged 4, but the button stays off until your balance is at least 8.
