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 · Brains

Context your AI can use.

Keep facts, decisions and notes in a Brain. Add the right ones to the message you're writing in an AI chat, and save a page selection with a right-click.

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.

One account. Three surfaces.

Fibonax ships as a Chrome extension, a web dashboard and a mobile website. Sign in once. Your tools 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 and review analytics. 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.

Questions, answered.

The short version of what people ask before they start.

What is Fibonax?

One place for your Snippets, Prompts and Brains. Snippets are reusable text you insert by typing a short trigger. Prompts are your best AI instructions, saved and ready to reuse. Brains hold what an AI should know about your work. You use all three from the Chrome extension, the dashboard and your phone, and they always show the same library.

Do I need to be technical to use it?

No. You write a snippet once, give it a short trigger and type that trigger wherever you need the text. Fields, dates and calculations are added from menus, not code. If you can fill in a form, you can use Fibonax.

Where does it work?

In Google Chrome on a computer, in any text field on any website: email, chat, documents and AI tools, with no setup per site. Browsers that install extensions from the Chrome Web Store work too. On the few pages Chrome keeps extensions out of, the right-click menu or a copy from the popup gets the same text in. On your phone, open app.fibonax.com/mobile in the browser, fill in a snippet and paste it into any app.

Which AI tools does it work with?

Any assistant you type into. Prompts and Brains go into ChatGPT, Claude, Gemini and the others, and the same context follows you when you switch. Fibonax is not tied to one AI.

Can I bring my snippets from another tool?

Yes. On the Snippets page, Import reads a Text Blaze export, a Fibonax export or a plain list of snippets. Text Blaze fields and conditions keep working as they are. You can export everything to a file at any time, so nothing is locked in.

Can my team use it?

Yes. Share a folder with your whole team or with chosen teammates, and everything inside it appears in their extension and dashboard straight away. You decide who can use, edit or manage each folder.

How much does it cost?

Anyone who signs up by December 31, 2026 keeps Fibonax free for life. From January 1, 2027, new accounts start with a free usage allowance and then pay only for what they use. There is no monthly or yearly subscription. See the pricing page.

Where is my data stored, and who can see it?

Your account and everything in it are stored in the European Union, in Ireland, encrypted at rest and in transit. Fibonax does not read the pages you browse and never sells your data. A Brain reaches an AI only when you choose to add it to a chat. The privacy policy has the details.
