In short

Say one sentence; the expense and the item are both recorded.

Fibi is a mobile app that turns a single sentence like “bought headphones for 3700 lira” into both an expense and an inventory record. Clear sentences are understood by a rule-based parser on the device; only unclear ones go to AI, and the amount and date are always verified in code. It also tracks installments, subscriptions, planned payments for the months ahead and investments. No account needed: the data stays on the phone. The app is free; more AI usage and price tracking come with the optional Fibi Pro.

04Usage flow

How is the product used?

A simple path from first use to seeing the finished result.

  1. 01

    Say or type it

    One sentence is enough: say it, type it or share a product link from a shopping app.

  2. 02

    Review and confirm

    The amount, date and category are picked out; if something is missing, Fibi asks instead of guessing.

  3. 03

    Two records

    Buy something lasting and both the expense and the item are created; groceries and other consumables are just an expense.

  4. 04

    Plan ahead

    Installments show up in the month they are due; follow the months ahead and the things you own in one place.
