Build with Nova
Your goals. Your structure. Nova’s help.
Think it through together, then turn it into a workspace. Nothing is created until you approve it.
Questions first
Nova asks what it needs before it drafts anything.
Every change is a version
Edit the draft yourself or tell Nova what to change.
Yours once approved
Approve, and your subjects, topics and dates appear.
AI-powered Second Brain
Your AI-powered second brain.
Subjects inside subjects, topics inside topics, and the notes and papers that connect them. Open any card to go deeper.
As deep as you think
Subjects inside subjects, topics inside topics. Open any card to explore inside it.
Connections you can see
Select a card and everything joined to it lights up.
Grows as you learn
Every subject, note, paper and task you add takes its place.
One connected workspace
Map it. Understand it. Plan it.
One topic, three views: where it sits in your second brain, your note with the Tutor beside it, and the day Nova helps you plan from both.
Notes and research
Learn from what you’ve already written.
Your notes and papers sit beside the Tutor. Choose a passage; it explains from your own words and keeps its additions apart from yours.
Bring a paper in with its link.
One note, filed where it belongs, with your own notes kept apart from the paper.

Nova for Chrome
A doubt mid-article? Ask it right there.
No copying into a chatbot tab and losing the answer in its history. Select the line, ask Nova, keep the passage under its topic, and write down what clicked in your own notes.
Ask where you read
Nova answers from the passage you selected, in a popup on the page. No new tab, no explaining the context again.
Kept where you’ll look
The passage and its page go under your subject and topic, and come up in the focus room when you study it.
Only when you click
It sees the address, the title and your selection, and only when you press a button. Nothing runs in the background.
Free on the Chrome Web Store. Connect it with a code from your Kivo account. On a phone, a bookmark saves any page too.
Proactive mentoring · on Telegram
A mentor that reaches out first.
Nova writes when it matters: today’s first block, a review that’s due, an exam close. Tap to start, or reply in your own words, in English or Hinglish.
One tap, real sessions
Start, pause and end from the chat. It’s the same session the web app shows.
Your tone, your language
Gentle to no-mercy coach. English, Hinglish or Hindi, following how you write.
Quiet when it should be
Not at night, not mid-session, at most twice a day. “Not today” pauses it to midnight.
Telegram is optional: everything works on the web, and connect it while you set up, or later in Settings.
Focus room
A room to think in.
A scene behind you, a sound you mixed, the clock in front, and everything you filed under the topic one click away.
Five living scenes
Aurora, Rain, Night sky, Embers and Forest, drawn as you watch. Nothing to download.
Sound you mix
Rain, café, fireplace, brown noise and more at their own volumes, or your own playlist.
Every session counts honestly
Timed or untimed. Sessions of ten minutes or more move your progress.
Your creature
A world that grows with you.
Every day you study, your creature’s world grows. Days in a row open new places in its village, and every five days of study is a new level.
Yours alone
Your terrain grows from a seed of your own, so no two worlds are the same.
Kind about time off
A missed week takes away some sparkle. It never brings fog.
Never a nag
Nova doesn’t bring it up in chat. It’s there when you want to visit.
Everything else
The rest of your workspace.
Small tools that keep the plan moving.

To do, In progress, Done. A task joins today only when you add it.

Common questions
A learning workspace with an AI mentor, Nova. You build a structure for what you're learning (subjects and topics, nested as deep as you need), keep notes and research papers inside it, see it all on a Knowledge Map, and plan each day from it. Progress is measured from the focus sessions you actually finish.
No. Nova asks questions, suggests and proposes. A plan for your day, a new workspace or a change to a note waits as a proposal until you apply it, and you can reorder, edit or discard it. What you approve is saved; nothing else is.
The previews on this page are samples that run in your browser: explore the map, step through Build with Nova, try the Tutor and Editor, and plan a sample day. They save nothing. To build your own, sign up; the Free plan needs no card.
Links from arXiv, a DOI, Semantic Scholar, OpenReview, PubMed and PubMed Central, or a direct PDF link. Kivo brings in the details and abstract, plus the full text where the source shares it openly (arXiv's HTML versions, Europe PMC's open-access set). It never fetches anything behind a sign-in or paywall; Nova can transcribe a PDF you point to or upload.
No. Kivo runs in your browser, on a computer, tablet or phone. If you use Telegram, connect it and Nova can start and log sessions there too; it's the same record either way.
There's a Free plan with everything in Kivo and a daily Nova allowance. Pro gives Nova a much larger daily allowance and starts with seven days free, no card needed. Your notes, knowledge and history stay yours on every plan.
