CipherWrite is a privacy-first writing and journaling app with true end-to-end, zero-knowledge encryption, designed for novels, private journals, and long-form writing that only you can read. It runs as a free, cross-platform PWA on Web, Mac, Windows, Linux, iOS, and Android, with client-side keys, anonymous sync, and no trackers or AI training on your data. CipherWrite adds optional, boundaries-respecting AI for brainstorming and editing, plus tiers from a free local-only plan to pro and enterprise options with encrypted cloud vaults, AI credits, image uploads, and self-hosted deployments

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.
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 PaulโElder intellectual standards so the AI stays a mirror, never a crutch.
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 surprisingโI 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 itโa 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 diaryโthe only difference is that now I'm hoping it can help others the same way it helped me.
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.
Expensive, and the pricing model changed, but it just works. I hope more competitors release equally good quality to have a more fair pricing model in the longrun.
So Iโve been playing around with Claude for a bit, and hereโs the vibe:
Honestly, it feels way more chill than a lot of other AI tools. Itโs super polite, doesnโt jump into assumptions too fast, and gives responses that are easy to read like talking to a thoughtful friend rather than someone in a hurry. Itโs surprisingly good at breaking down complex stuff into simple terms without sounding condescending, which I really appreciate.
In terms of creativity, Claude does pretty well โ whether I ask for a poem, a short story, or help brainstorming ideas, it doesnโt just give cookie-cutter replies. Thereโs a bit of personality there, like it tries to make things interesting rather than just factual.
On the downside? Sometimes it plays it a bit too safe. If you push for a bold opinion or a more adventurous answer, itโll often stay in the middle-of-the-road lane. And for niche topics, itโs not always as sharp as some other models unless you give super clear instructions.
Also, itโs fast no long pauses or overcomplicated explanations which makes it nice for quick back-and-forth.
Claude Sonnet 3.5 is amazing for coding! I used to use the chat interface and copy-paste, but now I use aider.chat. Aider works in a git repo and forces Claude to only make the changes you requested. Changes are easy to revert.
A downside: Code is not always what I want. I try to make it do work in small chunks and this helps. Excels at writing boilerplate-y code that tends to be a little different on different websites.
Two helpful styles of prompts:
Using it for Python/Django/HTMX/AlpineJS. Django templates mixed with JS are no problem.

Drop an image into Claude or ChatGPT asking it to "recreate this." The result? The LLM guesses styles. Is that padding 16px or 24px? Is that blue #3b82f6 or #2563eb? Is the shadow 0 2px 8px or 0 4px 12px? Pure hallucination. - Source: dev.to / 8 months ago
