Marc.
Turn your ideas into reality
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Every idea sounds good in your own head. Marc is where you find out whether it holds up.
The book you've wanted to write for years. A year in Lisbon. The podcast with your best friend. The little café. Marc is a thinking board for ideas of every kind – built for iPad, iPhone and Apple Pencil. You say one sentence, Marc asks two questions and builds your first board from it: clusters for the big themes, thoughts hanging off them, open questions as sticky notes beside them.
Then comes the part no blank page gives you: pushback.
AN AI THAT DOESN'T APPLAUD
Marc is an otter with opinions. He listens, digs deeper and looks at every thought from four angles:
• Thinking further – opens directions you wouldn't have reached alone.
• The investor's view – what carries, what costs, what scales.
• The customer's view – honest objections from the person who's meant to use it.
• The sceptic – finds the unchecked assumptions. Kind, but incorruptible.
Plus your own thinking styles: the CFO, operations, your toughest friend – as many as you like.
Suggestions appear as dashed cards at the edge of a thought. Accept or dismiss is always your call – nothing lands on your board unasked.
ASK YOUR BOARD
A conversation about everything on it. Marc answers from what's actually on your board – and says so when something is missing.
FROM SCATTERED THOUGHTS TO A PLAN
• Coverage check – where your board is still thin.
• Decision log – what you accepted, explored or dropped, and when.
• Plan draft – the whole board distilled into a text you can show someone. Honest gaps included.
YOUR BOARD, YOUR RULES
• Categories that fit the board – rename, recolour, add your own.
• Checklists, sticky notes, photos and shapes right on the canvas.
• Apple Pencil sketches where words don't reach.
• A calm paper-and-ink design that stays out of your way.
THINK TOGETHER
Share a board by invitation or link. Editors work live on the same sheet – cursors, movements, even pencil strokes in real time. Reactions and comments live on the thought, not in a chat beside it.
MARC STAYS WITH IT
If you like, Marc reminds you – never with a slogan, always with something from your board. And if you don't come back, he goes quiet.

New: open, connect and draft ideas.
• New board – start with Marc or with a blank sheet. Marc asks a few questions about your idea and builds a first board from it.
• Categories that fit your idea – when drafting, Marc sets up categories right away: "Characters" for your novel, "Location" for your café.
• Everything is an idea – every card is an idea, connections show how they relate. Add new connected ideas directly.
• The new idea card – tap an idea and it opens in the center: title, notes, status and every action at a glance.
• See more as you get closer – zoomed out, cards show just the title; up close, notes, tags and status.
Also:
• New boards start with gravity off – ideas stay where you put them.
• Reactions and comments now scale with the board.
• The coverage check has been removed.
• New illustrations of Marc and lots of small improvements.
