Questions & Answers

As answered by people managing Obsidian and CipherWrite.

Why should a person choose your product over its competitors?

CipherWrite's answer:

Why writers choose CipherWrite

  • Your writing stays truly private. Everything is encrypted on your own device with AES-256 and Argon2id before it ever leaves. The keys live with you, not on our servers, so even we cannot read a word of it.

  • AI that helps without eating your book. Tools like Sudowrite and Grammarly only work by shipping your whole manuscript to the cloud. CipherWrite's AI only ever sees the snippet you hand it, so you get brainstorming, humanizing, and editing help while your full draft never leaves your control.

  • Writing Guides that teach the craft. Deep, research-backed guides on story structure, the psychology of unforgettable characters, world-building, narrative pacing, and subtext. Most apps hand you a blank page and walk away. We hand you a blank page and a writing education to go with it.

  • A Critical Thinking Gym for your brain. You write your own argument first, the AI challenges you with Socratic questions, then scores your reasoning and shows your blind spots. It sharpens your thinking instead of doing it for you.

  • Built for authors, not repurposed from a notes app. Real chapter structure, a proper book workflow, and Kindle-ready export, all built in from the start.

  • Works everywhere and free to start. Runs in any browser on any device, with a genuinely free tier. Privacy is not something we make you pay extra for.

In short: CipherWrite is the only writing app that combines real zero-knowledge encryption, AI that never sees your whole book, craft guides that teach you to write better, and a thinking gym that sharpens your mind, all in one free app that runs anywhere.

What makes your product unique?

CipherWrite's answer:

In an age where every keystroke is tracked, scanned, and graded by opaque algorithms, writing in a conventional cloud editor means your private drafts and journals are being mined for data. CipherWrite was built to be different a writing sanctuary where you can finally be alone with your own mind.

Your words are encrypted on your device with AES-256 before they ever touch the cloud, secured by Argon2id. The keys never exist on our servers, so even if CipherWrite were compromised, your data stays unreadable. It's true zero-knowledge privacy: not even our team can see what you write.

Beyond the blank page, CipherWrite helps you grow as a writer. Its Adaptive Creative AI respects your boundaries brainstorm ideas, humanize drafts, and check readability without your work being used for AI training. Deep, research-backed Writing Guides teach the craft itself, from story structure and character psychology to world-building and narrative pacing. And the Critical Thinking Gym turns reasoning into a daily workout: you think first, AI challenges you with Socratic questions, then scores you on the nine Paul–Elder intellectual standards so the AI stays a mirror, never a crutch.

What's the story behind your product?

CipherWrite's answer:

I was going through a difficult time. Every morning I would wake up feeling overwhelmed, carrying around thoughts and emotions that I didn't know how to process. Most of my friends were busy, and honestly, I didn't really have anyone I felt comfortable talking to about some personal things.

One day, I picked up an old diary and started writing everything down. It helped, but I constantly worried that someone might read it because many of my thoughts were deeply personal.

As a developer, I thought, "Why not build a secure digital space for myself?"

That idea eventually became CipherWrite.

My first goal was simple: privacy. I wanted a place where I could write freely without worrying about someone reading my thoughts. So I designed the platform around that idea and built a writing space where privacy came first.

As I continued writing every day, I noticed something surprising—I felt lighter. Writing had genuinely helped me process my thoughts and emotions. What started as a tool for myself slowly became something much bigger.

I've always wanted to build a SaaS product, and I've also dreamed of writing books one day. As I spent more time using the app, I realized it could become a safe space not only for private journaling but also for writers and authors who needed a distraction-free place to think, create, and write without fear of losing ownership of their work.

The first version was incredibly simple. It wasn't polished, and it had only the features I personally needed. But because I used it every single day, I kept discovering small things that could make the experience better. Every improvement came from solving a problem I had while writing.

Over time, CipherWrite evolved into much more than a private journal. I added tools for brainstorming, organizing ideas, critical thinking, creativity, and long-form writing. Some features were inspired by my own workflow, while others came from listening to people who enjoyed using the platform.

Building it has been one of the most rewarding experiences of my life. It started from a difficult chapter when I simply needed a place to empty my mind. Today, it has become the writing space I wish had existed when I first needed it—a place where people can think freely, write honestly, and create without worrying about privacy.

I still use CipherWrite every day. It's still the first place I go whenever I need to organize my thoughts, write down ideas, or simply clear my mind. In many ways, I'm still building the product for the same person who first opened that old diary—the only difference is that now I'm hoping it can help others the same way it helped me.

How would you describe the primary audience of your product?

CipherWrite's answer:

CipherWrite is for privacy-conscious writers. Mainly authors and novelists drafting unpublished books, plus private journalers and journalists, who want AI writing tools without ever letting anyone, including the app itself, read their work.
