Prompts

Your best instructions, structured and ready to execute.

What's inside

Everything text expansion should be. Plus the two things it isn't.

A drop-in replacement for TextBlaze, TextExpander, and Magical, with live formulas and a reusable prompt library on top.

01 · Triggers

Type a short tag. Watch a full template appear.

::quote expands into a 200-word multilingual quote. Works in Gmail, Notion, Slack, your CRM. Anywhere you can type, or from the right-click menu when you'd rather pick than type.

02 · Formulas

Real math, inline.

Totals, discounts, fees, net prices: calculated the instant a template expands. Conditionals, date tokens, and greetings that agree with the guest's name. CSP-safe parser, no eval.

03 · Prompts

A library of reusable prompts.

One-shot and few-shot prompts for ChatGPT, Claude, and any model, stored next to your templates. Type """ to browse them, or give a prompt its own shortcut and expand it straight into the box.

04 · Cloud sync

One library. Every surface.

Backed by Supabase, encrypted at rest. Write once in the dashboard; the extension and your phone read the same library, refreshed in the background and again every time you open them.

05 · Notion sync

Edit where your team already works.

Mirror a Notion database as your library, one-way or two-way. Reviewers comment in Notion; expansions update in the extension within the minute.

06 · Mobile

Your library, on any phone.

Browse, search, and copy from iOS and Android in the browser. No laptop, no download. Pin what you use daily, fill a snippet's fields, copy the finished text, and add notes to your Brains on the go.

07 · Analytics

See what your team actually types.

Every expansion is counted. Top triggers, usage over time, and a contribution heatmap show which snippets earn their place, and which ones nobody has touched in weeks.

08 · Security

Your account, on your terms.

See every signed-in device, review recent login activity, and sign out everywhere in one click. Each surface holds its own session, so revoking one doesn't lock you out of the rest.

09 · Team workspace

Share a folder. Your team types from it.

Share a folder with the whole team or specific teammates, at View, Edit, or Owner access. Every snippet, formula, and prompt inside it shows up in their dashboard and extension the moment you share. Each one carries who wrote it and who touched it last, and the whole workspace wears your company logo and cover.

No app to download

One account. Three surfaces.

Fibonax ships as a Chrome extension, a web dashboard, and a mobile website. Sign in once. Your snippets and formulas are everywhere, instantly.

Chrome Extension

One-click install from the Chrome Web Store. The popup puts every snippet at your fingertips while you type, in Gmail, Slack, Notion, your CRM, anywhere.

Ready to install

Web Dashboard

Manage your full library from any browser. Create folders, write snippets with live formulas, share folders with your team, review analytics, and configure Notion sync. Nothing to install.

Lives in your browser

Mobile Website

Browse, search, and copy snippets, prompts and Brains on iOS or Android, straight from Safari or Chrome. No download, no app store. Just open a URL and you're in.

No download required

Built for scale and security

Fibonax scales with your team without loosening what protects your data. Access is enforced by the database itself, not just the interface, whether you're a "team" of one or an org of hundreds.

EU data residency

Your snippets, prompts, and formulas live in an EU-region Postgres cluster. They never leave it.

Row-level security

RLS is active on every table. A row you can't read is refused by Postgres, not merely hidden by the UI.

Per-user authentication

Dashboard, extension, and mobile each authenticate as you with your own token, never a shared key.

GDPR-aligned handling

Documented collection, retention, and deletion, with a published privacy policy, terms, and cookie policy.
