How it works

Every assistant, one calm workspace.

01

Organize

Sort every conversation into folders and tags that finally stick, across every site you use.

02

Search

One fast, local index finds any thread by word, tag, or platform. No scrolling separate histories.

03

Prompts

Keep a library of reusable prompts with variables, and drop them into any chat with a slash.

Private by architecture

Your chats never leave the browser.

Skeinos indexes everything locally. There is no account, no telemetry, and no analytics — not opt-in, not off-by-default, none at all. In normal use the extension makes no network requests whatsoever.

You don't have to take our word for it. Skeinos is open source, so the stays-on-device boundary is something you can read in the code rather than something you're asked to believe in a policy.

Coverage

Live today, growing steadily.

Works right now on the four assistants you use most, with more on the way.

Questions

Good to know.

Is Skeinos free?
Yes. The full organization, search, and prompt library is free, and no account is required.
Does my conversation data leave my device?
No. Conversations are stored and searched locally in your browser. There is no account and no telemetry of any kind, so nothing is uploaded. In normal use Skeinos makes no network requests at all — the one exception downloads a corrected selector file when a chat site changes its layout, and it sends nothing about you.
Is Skeinos open source?
Yes, under the GPL-3.0 licence. A privacy promise you can't inspect is just a promise, so the code is public: you can read exactly what it does, check every permission it asks for, and build it yourself.
Which browsers and AI sites does Skeinos support?
Skeinos runs on Chrome and Firefox and works on Claude, ChatGPT, Gemini, and Perplexity. It is built on Manifest V3, with more platforms on the way.
