• Alkane — only single bonds (C–C), “saturated”.
• Alkene — at least one double bond (C=C), “unsaturated”.
If two carbons share a double bond instead of a single one, do you think the molecule ends up with more or fewer hydrogens attached?
A real exchange from the actual product — not a mockup.
How it works
Type any subject
No dropdown, no fixed list — "organic chemistry," "Python recursion," whatever you're studying.
Chat & learn
Ask questions, attach a photo of a problem, get step-by-step help — real math and code rendered properly.
Pick up anytime
Every session is saved. Come back, continue where you left off, or download it as study notes.
Learns through dialogue
Instead of dumping a final answer, the tutor asks short guiding questions first — the same way a real tutor draws you toward understanding instead of just telling you.
Upload a photo of the problem
Snap a photo of a textbook problem or handwritten equation — the tutor reads what's actually in the image and walks through that exact problem, step by step.
Real equations, real syntax highlighting
Equations render as proper typeset math, not raw $x^2$ text. Code examples show up in a real, readable code block — not a wall of asterisks.
Adapts as you go
Pick Beginner, Intermediate, or Advanced when you start — or let the tutor figure it out. Either way, it keeps reading how you respond and adjusts pace and complexity through the conversation.

Step-by-Step Solutions
Complex problems get broken down into clear, ordered steps — not a single wall of text.
Adaptive Difficulty
Set a starting level, and the tutor keeps adjusting explanation depth as the conversation goes.
Cross-Subject Help
Ask a follow-up in a different subject mid-session — the tutor follows you there instead of resisting.
Export Conversations
Download any session as a plain-text transcript to keep as study notes.
Voice Input
Speak your question instead of typing, on any browser that supports it.
Multilingual Tutoring
Search and pick from over 100 languages at the start — Hindi, Spanish, Arabic, Mandarin, and more — the tutor replies in that language throughout.
Frequently asked questions
-
Is the AI Tutor really free?
Yes — no subscription or payment required. You just need a free DigitalStudy.org account, since sessions are saved to your account so you can pick them up later.
-
Is there a limit on how many questions I can ask?
There's a generous daily message limit per account, purely to keep the service running smoothly for everyone — high enough that a normal study session won't come close to it.
-
What subjects does it cover?
Any subject you type — there's no fixed list to choose from. Math, science, programming, languages, history, whatever you're studying.
-
Can I switch subjects in the middle of a session?
Yes. If your question drifts into a different or related subject, the tutor follows along instead of redirecting you back.
-
Does it work on my phone?
Yes, the interface is responsive and works on phones, tablets, and desktops.
