No accounts. No tracking. No cloud. Every 864zeros extension runs entirely on your device — and most are free, forever.

Save the page you're on to a local read-later list with notes & tags. Read later or export to Markdown.

Park a window of tabs as one labeled set — annotate each, then reopen or export to Markdown.

How we work

Radical transparency, by design. We tell you exactly how the tools work and how the company runs.

Your data never leaves your device. We run no server for your content — there's nothing for us to lose, leak, or sell.
Honest pricing. Most tools are free forever; paid unlocks are a one-time few dollars, never a subscription. Premium polish, impulse price.
Open where it counts. We publish reusable feature "bricks" as free open source — the components behind our products.
AI-augmented, and open about it. 864zeros builds with substantial AI assistance under human direction and review. The polish is real; we're just efficient.
