An activity grid
for your words.

Writers need a dopamine hit, too. Inkdiff runs in your Mac's menu bar, tracks your Google Docs output, and turns your daily word counts into a viscerally satisfying 3D cityscape.

One job, done beautifully.

Engineers have green contribution grids that prove they showed up. Writers just have a growing pile of Google Docs. Inkdiff ports the mechanic of the contribution graph to long-form writing, giving you a passive feedback loop that respects your flow. No project management, no AI, no goal-setting paywalls. Just your accumulated work, made visible.

The 2D Grid

The classic 52-week by 7-day contribution graph, reimagined for writers. Color intensity scales with your word count. Hover any square to see exactly how much you wrote that day.

The 3D Cityscape

A single keystroke toggles the grid into an isometric Monument Valley-style cityscape. Each day becomes a tower, rising based on your output. Watch your months form a skyline.

Isometric Cube

Radical Privacy

Inkdiff reads your documents the way a spell-checker does — locally, transiently, to compute a single number. Your writing never leaves your Mac, is never stored by Inkdiff, and is never seen by anyone. The only thing Inkdiff saves to disk is how many words you wrote each day.

Menu Bar & Widgets

Inkdiff lives quietly in your menu bar, showing today's count (e.g., ✍ 847). A quick click reveals your graph. Prefer the desktop? Drop a beautiful macOS widget onto your screen.

Word-Powered Flora

A gentle, Tamagotchi-style nudge. Set a daily word count goal to nourish a digital plant living in your menu bar or widget. Hit your goal, and it blooms. Miss it, and it slowly wilts.

Spotify Wrapped, for Words

At the end of the year, Inkdiff generates a beautiful, shareable cinematic render of your entire year of writing. Your tallest towers become a testament to your most prolific days.

Frequently Asked Questions

Does Inkdiff read my actual writing?

Yes, but strictly transiently. Google's API requires read access, so Inkdiff fetches your document temporarily to extract the word count. The content is immediately discarded — like a calculator that shows you a result without keeping your inputs. It's never written to disk, never logged, and never sent to a server.

Is this a subscription?

No. The core Inkdiff app (with Google Docs support) is 100% free, forever. Inkdiff Pro, which unlocks third-party apps like Notion and Obsidian, is a single $4.99 lifetime purchase. No recurring fees.

What platforms does it support?

The free version supports Google Docs. Inkdiff Pro adds support for Notion workspaces, local Obsidian vaults, Bear, and Apple Notes. We are constantly adding new integrations.

Does it work offline?

Yes! For local apps like Obsidian and Bear, it works seamlessly offline. For cloud apps like Google Docs or Notion, Inkdiff will queue your word counts and sync the metadata graph the next time you connect.
