What If Someone Had Read
Every Word You've Ever Written?

You've built something intricate, layered, alive. Hundreds of characters, locations, and threads woven across chapters. It's a lot to maintain.
But what if you had someone there with you every time you sit down to write. Someone who's taken in every page, remembers every detail, and is always there when you need to talk through your world.

Introducing WordSpark

A tireless writing companion — from first draft to final page.

Total Recall

Every character, location, and event — remembered and traced back to your words.

Always Available

Ask anything about your world. Get answers grounded in what you've actually written.

A Careful Eye

Spot contradictions and loose threads before they become problems.

Grows With You

From first chapter to final draft — every detail tracked as you write, nothing lost along the way.

Story Bible

Your Story Bible Builds Itself

Mark a chapter as canon and WordSpark reads it the way a careful editor would — pulling out characters, locations, events, and relationships, tracing each one back to your text. No spreadsheets. No wiki. Just your story, understood. All of it processed locally on your Mac.

AI Reader

Context Is Built-In

Ask anything about your world. Answers draw from your prose, notes, and outlines — no context-pasting required. Brainstorm, fact-check, or explore your story’s deeper patterns, always grounded in what you’ve actually written. The AI runs on your Mac, so your prose isn’t sent to a cloud model to answer.

Consistency

Catch Contradictions, Plot Holes, and Inconsistencies.

Because WordSpark builds your story bible as your writing progresses, it is perfectly situated to spot mistakes that might otherwise have been missed.

Memory

No More Starting Over.

WordSpark remembers without requiring you to paste in chapters’ worth of context on every conversation. Once it is canon, it is known.

Why this is possible

Wondering how AI can be included for $50 a year?

WordSpark runs the AI on your Mac. Not in a data center.

Your words aren't training data.

Local AI means that your prose doesn't get sent to any of the big cloud models for processing or training. WordSpark does not train its AI on your prose.

Works offline.

Plane, cabin, train tunnel — the AI travels with you.

No usage caps.

Brainstorm all day. No token meter. No “you’ve hit your limit.”

Yours to keep.

You don't need an active subscription to keep writing. Because the AI runs on your Mac, the copy of WordSpark you've installed stays yours — renew for new features, not to keep your access.

Requires an Apple Silicon Mac (M1 or newer). Intel Mac support is on our roadmap.

Built by Writers Who Couldn’t Find the Right Tool

We spent years writing fiction with cobbled-together tools — spreadsheets for characters, wikis for worlds, and our own memory for everything else. We built WordSpark because it didn’t exist.

Your story is waiting.
