Nobody's taking attendance.
Your board exam still is.
Twelfth is an AI study coach built for students doing Class 12 through open school. It plans your week, marks your written answers the way an examiner would, and explains the step you actually got wrong. English and Hindi.
Free for 3 days, then ₹499 a month. Cancel any time. Under 18? A parent approves first — it takes them two minutes.
It's 11pm and you're stuck on one question.
Open school means you set the pace. It also means there's no one down the corridor to ask. Three things go wrong, and they compound.
No one to ask
You reread the same paragraph four times. A video explains the topic but not the bit you're stuck on. So you skip it — and it's on the paper.
You can't tell if it would score
Your answer looks right to you. Whether an examiner gives it five marks or two is a different question, and you find out in March.
Tomorrow is a guess
Revise what you like, avoid what you don't. The weak topics stay weak because nothing forces them up the list.
Not a chatbot. A coach that has read your last sixty answers.
Saathi is the coach inside Twelfth. It knows your subjects, your exam date and every mistake you've made so far — so the help is about you, not about the topic in general.
Marks your answer
Write it out, photograph it or type it. You get a band, the marks you lost, and why — labelled as recall, concept, calculation, application, structure or language, so the pattern becomes visible.
Explains the step you missed
Not the whole chapter again. The specific move you didn't make, in the language you chose, with a fresh question straight after to check it landed.
Plans the week backwards from your exam date
Tell it your date and the hours you can give. The topics you keep losing marks on move to the front, whether you like them or not.
Saathi will not write your TMA, your exam answers or your personal statement for you to hand in. It will take your draft apart and tell you what an examiner would think of it. That line isn't negotiable, and it's the reason the marking is worth trusting.
Five now. Yours next, if enough people ask.
Every topic is mapped to the NIOS syllabus, in English and Hindi. Ask for a subject inside the app — when enough students want the same one, it gets built.
Studying tonight, in about five minutes.
Your subjects and your date
Pick what you're sitting, say when, and how many hours a day you can honestly give. First name only — we don't ask for your school, address or photo.
A parent says yes
If you're under 18, we send your parent a short note on WhatsApp explaining exactly what we collect. They tap agree. Two minutes, and nothing about you is stored until they do.
Three days free
Mark a real answer, get a real plan, see whether it's worth it. Cancel inside the trial and you're not charged.
You decide before anything is stored.
Your child cannot use Twelfth until you agree, and you can withdraw that at any moment by replying WITHDRAW on WhatsApp. Here is exactly what you're agreeing to.
Time, topics and what needs work. Never their conversations, their answers or their marks — those belong to them.
Less than one hour of tuition a month.
Both plans include everything — every subject, unlimited planning, answer marking every day. Three days free first, on either.
Works out at ₹433 a month. Covers a full run at the boards.

Is this from NIOS?
No. Twelfth is an independent app made by Fusionpact. We are not affiliated with, endorsed by or connected to the National Institute of Open Schooling. We follow their published syllabus — that's the whole relationship.
Will it do my TMA for me?
No, and we won't build that. It will mark your draft, show you where the marks are going and make you rewrite it. Work you hand in has to be yours.
Does it actually work in Hindi?
Yes — explanations, marking and the coach, all in Hindi, using the terms your NIOS book uses. Switch language whenever you like.
I'm over 18. Do I still need a parent?
No. The parent step only applies to students under 18. You sign up and start straight away.
There are fewer evenings left than you think.
Start tonight. Three days free, and you'll know by Wednesday whether it's for you.
