Built by a Founder Who Writes Everything by Hand.
InkThink is created by Sundaram Applied Technologies, Inc. in Silicon Beach, Venice, California — focused on helping people boost creativity and productivity through the timeless power of pen and ink.
From Frustration to InkThink™
InkThink didn't begin as an app. It began as a frustration — and a vision. For years, I used every digital planner, notes app, and PDF template I could find. They all shared the same flaw: they forced my thinking into someone else's boxes. Static pages. Rigid templates. Linear workflows. None of them captured the way I actually think — spatially, visually, fluidly, with a stylus in hand.
So I built InkThink. Not as another planner. Not as another notes app. But as a modular thinking environment designed for people who think with their hands, their eyes, and their intuition — introducing Atomic Ink™, Ink Thoughts, and Intelligent Ink™ that can be moved, grouped, transformed, and repurposed without losing the tactile joy of handwriting.
We believe technology makes it possible to improve creativity, productivity, and personal growth. Our vision is that InkThink will help blend the best of both worlds — the classic pen and planner with the power of technology.

Why InkThink Exists
Static tools couldn't capture how I actually think — spatially, visually, with a stylus in hand.
Your ink should be intelligent — not just marks on a PDF that don't update across views.
Modular thinking means your ideas should be blocks you can move, group and transform freely.
Stylus-first creativity deserves a first-class tool — not an afterthought bolted onto a general app.
Offline-first matters — your thoughts shouldn't depend on a wifi signal to be captured.
Tools should match how your mind works — not force your mind to match the tool.
