Sincerely

Write sincerely. One scene at a time.

Sincerely does one thing: helps you write your novel, scene by scene, without getting in the way. No sprawling feature sets, no steep learning curve, no subscription. Just a quiet, focused space to put your scenes in order, fill them with words and finish your novel.

How it works
01
Scene-first

Every novel is a collection of scenes. Sincerely makes scenes the primary unit of your work — write them freely, organise them into chapters when you're ready.

02
Structured or blank

Start from scratch or choose a template — Save the Cat or Three Act — to give your story a backbone before you begin. More templates are on the way.

03
Nothing you don't need

Sincerely is deliberately small. Features are added carefully and only when they earn their place. The goal is a tool that gets out of the way.

04
Free while we build

Sincerely is free to use while it's in development. When paid features arrive, they'll be priced to reflect real value — not what the market will bear.

Getting started
1
Add a novel

Give your project a title, set an optional word count target, and you're in.

2
Choose a template

Start blank, or pick Save the Cat — 15 beats ready to fill — or Three Act for a simple four-part structure.

More templates on the way

3
Write your scenes

Each scene has its own writing space. Add status, POV, location, timeline and a word count target if you want them — none of it is required.

4
Drag to chapters

When you're ready, drag scenes into your chapters. Reorder freely. Scenes can be returned to the pool at any time.

Early days

Sincerely is in active development. The writing experience is real and usable today — scenes, chapters, templates, themes — with more on the way. Questions, thoughts, or suggestions are always welcome.

Terms & Privacy

Your writing stays yours

Sincerely is an independent product currently in alpha. Your writing is saved locally in your browser and is never transmitted to or stored on any server. No account is required. No data leaves your device.

Because your work lives in browser storage, it is tied to this specific browser on this specific device. Clearing your browser storage will permanently delete your work. Use the built-in TXT or JSON export regularly to keep backups of your writing.

Sincerely uses no tracking, no analytics, and no third-party scripts beyond the fonts and SortableJS library loaded at startup.

A future version of Sincerely will offer optional cloud sync. At that point, full terms covering data storage, privacy, and pricing will be published and agreed to separately. Cloud sync will always be opt-in — local storage will remain the default.

Sincerely is provided as-is during the alpha period. While every effort is made to ensure stability, no guarantees are made regarding data integrity or availability. Export your work often.
