The quiet connector
Not a fourth app. The hub that makes the other three a family.
kaampi Codex has no editor, no canvas, nothing to type into. It's a small service that runs quietly on your own computer, so Write, Explore, and Comic can share a world — the same characters, the same locked facts, the same whole series — without any one of them losing control of their own.
Most app families make you pick a bad trade-off
Codex is the attempt to not make you pick either one.
One shared database
The usual way to connect a family of apps: force everything into one schema everyone must agree on. Fast to build, brittle to own — any app's bug or bad write becomes everyone's problem.
Or: totally siloed apps
The other usual way: each app keeps entirely to itself. Safe, but your characters, world, and whole series live in four unrelated copies that quietly drift apart.
Codex: shared, but never owned by force
Every workspace keeps one owner. Other apps only ever see what that owner explicitly shares, and can only ever propose — never silently overwrite — a change to it.
How one world reaches four apps
Each app keeps talking to Codex, never to each other directly. Codex only ever enforces one rule: nothing moves between apps without the owning app's say-so.
Owns its manuscripts
Owns its sketches
Owns its panels
Private by default
A new manuscript or sketch is visible only to the app that created it, until that app's author explicitly turns sharing on.
You grant access, app by app
Share a story with kaampi Comic for illustration, or with kaampi Explore for brainstorming — independently, and only as far as you choose.
Proposals, never silent overwrites
If another app suggests a change to something you own, it arrives as a proposal. Nothing becomes fact in your world until you accept it yourself.
Backups, and a door only you can open
Codex keeps encrypted local backups and a small admin page for approving new app connections — guarded by a key the first time, and a password of your own choosing after that.
A whole series, not just one book
When a kaampi Write series spans a shared Story Bible across every book and language version, that's exactly what reaches Comic and Explore through Codex too — one series' canon, consistent everywhere it's shared, not re-taught app by app.
How sharing actually happens
No app can reach into another's world. Every connection runs through the same four steps.
A workspace starts private
Every new manuscript or sketch begins as a private snapshot, visible to nobody but the app that made it.
You mark it shareable
The owning app's author turns a workspace into a shared manuscript — still only as a deliberate choice.
You grant access, app by app
Comic gets read access for illustration, Explore gets it for brainstorming — independently.
Changes arrive as proposals
A reader app can suggest an edit, but only the owning app can accept it into its own truth.
Where it actually lives
Codex isn't a cloud service with your name on an account somewhere. It's a small program on your own computer.
Runs on 127.0.0.1
Codex binds to your own machine's loopback address. It was never built to be reachable from the open internet.
Installs itself quietly
The first kaampi app you install sets Codex up in the background — there's no separate download to remember.
Backs itself up locally
Scheduled encrypted backups live next to your data, not in a third party's cloud.
Sharing a world shouldn't mean handing over the pen.
— the whole reason Codex existsFree forever. Supported by writers.
kaampi Codex is free, open source under GPL 3, and completely independent — no subscriptions, no venture capital, and no telemetry. It's the quiet infrastructure that makes the whole family possible; if that's worth something to you, you are warmly welcome to support continued development.
Questions people ask first
Do I ever open kaampi Codex myself?
Rarely. Day to day it works invisibly behind Write, Explore, and Comic. Its admin page exists mainly for approving a new app the first time, and for backups.
How is the admin page protected?
By a 64-character key the first time, and afterward by a password of your own choosing — hashed with a slow, deliberately expensive algorithm rather than stored or compared as plain text.
Can one app see everything another app has?
No. Each workspace starts private to the app that created it, and only becomes visible elsewhere through an explicit grant.
What happens if I only ever use one kaampi app?
Nothing changes for you. Codex still runs quietly underneath, but there's nothing to share and nothing to decide.
Is kaampi Codex open source?
Yes — GPL 3, the same license every kaampi app uses. Nothing about how your world is shared between apps is a black box.
How much does it cost?
Nothing. kaampi Codex is free, open-source software — no subscription, no upsell later. If you find it valuable, you are welcome to buy a coffee to help keep development going.
