API

Every shared wiki is an endpoint. Raw markdown and index.json for any AI.

How It Works

From blank page to a wiki you own in three steps.

Simple on the surface; underneath, a storage model you can verify with your own eyes — a markdown file sitting in your own Google Drive.

01
Sign in and type.
Name your wiki, sign in with Google, and start typing. WikiSys creates a folder in your Drive with the wiki inside as wiki.md. Every # heading becomes a new page. Keep as many wikis as you like — home, work, side projects.
02
Stored in your Drive.
Your wiki lives in a folder at the top of your Google Drive — storage you can check anytime. Switch machines? Paste the Drive link and everything's back. Each wiki is one .md file: email it, back it up, open it in any markdown app.
03
Share — with people or AIs.
Create encrypted share links that hide your Drive folder's location — plain or password-protected. Recipients read and write without seeing where the wiki lives. The same links serve raw markdown and an index API for any AI assistant.

Storage & Sharing

Your storage. Your links. Our servers hold nothing.

Your content lives in your browser and your own Google Drive. Even public wikis are read straight out of the owner's Drive folder.

Three ways to share

Every wiki is private until you share it. Each link type trades convenience against how much it reveals.

  • Encrypted link: one URL — recipients see the wiki, never where it lives. Your Drive folder address stays private.
  • Three levels: Open — link holders read & write; Write-protected — anyone reads, editing needs a passphrase; Locked — separate read and write passphrases. Drive's own permissions stay the final authority.
  • Or grab the file: it's plain markdown in your Drive — email it, back it up, open it anywhere.

Built for LLMs

Every shared wiki doubles as an API: fetch raw markdown in one request, or the index to pick just the pages an agent needs.

GET /api/v1/links/<link>/raw GET /api/v1/links/<link>/index.json { "pages": [ { "slug": "runbook", "title": "Runbook", "summary": "Deploy steps.", "bytes": 4812 } ] }

FAQ

Common questions.

Where your content lives, how the format works, and how sharing keeps you in control.

Do I really own my data?

Yes, verifiably: your wiki lives in a Google Drive folder you own and can open yourself — the folder link is shown right in the app. Nothing sits on WikiSys servers. Each wiki is a plain markdown file — no export needed, because it's already in a format everything can read.

What if WikiSys shuts down?

Nothing happens to your data. It's a markdown file in your Drive: open it in any markdown app, another wiki tool, or a similar service. That's the point of starting as one file — your wiki is easy to transport and never trapped.

How do share links work?

Every share link is an encrypted URL that hides your Drive folder's location. Three protection levels: Open, Write-protected, or Locked (separate read and write passphrases). Google Drive's own folder permissions remain the final authority.

How do AIs use my wiki?

Every shared wiki is also an API: raw markdown in one request, or an index of page titles, summaries, and sizes so an agent fetches only what it needs. Keep a portable skills.md wiki and any assistant can load your knowledge anywhere.
