The human thinks. Hyphælium carries.
Your best thinking now happens in conversation with AI — but when the session ends, it's lost in a multitude of other conversations. Hyphælium quietly catches every thread worth keeping, across every platform — and gives you one place to find any of them again.
Works across every major AI platform
The idea
Every day you have conversations with AI that hold genuine insight — a strategy refined, a problem solved, a connection made. Then the window closes, and the thread is gone.
Hyphælium is the network beneath. It captures a lightweight breadcrumb of each conversation worth keeping — the platform, the opening words, the way back — and holds it, ready to surface the moment you need it.
One click. No interruption. Your thinking, preserved and connected over time.
"For the people whose ideas are worth keeping."— The Hyphælium principle
The real difference
Your thinking isn't really lost — it's unfindable, scattered and buried across every AI you use. Hyphælium gives it one home, and one way back.
When a conversation is worth keeping, press the small green button. One click leaves a breadcrumb — the essence, not the noise. No new workflow to learn.
Claude, ChatGPT, Gemini, Copilot, Perplexity — every thread worth keeping lands in one place. Your thinking, no longer scattered across five walled gardens.
Half-remember a brilliant exchange but not which AI, or when? Search your whole vault at once and surface the exact thread — no matter where it happened or how long ago. This is the part no platform can do for you.
Not on Chrome, or can't install extensions? Hyphælium also works as a userscript via Tampermonkey — see the guide.
Your privacy is the architecture
Hyphælium saves a breadcrumb, not the whole conversation. When you save a thread, we record the platform, the link back, and the opening words of your first message — enough to find it again instantly. The rest of the conversation never leaves the platform that created it.
Your vault is yours alone. Your breadcrumbs are stored against your account and no one else's. We don't sell data, we don't show ads, and we have no reason to read your thinking — only to help you return to it.
"The conversation stays where it was born. Hyphælium simply remembers the way home."— How the vault works
In tribute
Lady Eve Balfour · 1899–1990
who taught us that the soil is a living network — that what flourishes above depends on the unseen threads beneath. Hyphælium carries that wisdom into the life of the mind.
Inspired by the mycelial networks that quietly bind a forest — and connect what would otherwise stand alone.
