Janka

Know what to reorder before you run out.

Janka is AI inventory forecasting for manufacturers. It reads what a plant actually uses, works out when to reorder and how much, and drafts the purchase order for a person to approve. It began as a REKA client build and is now an AntaraX product.

“What should we reorder, and how much, before we run out?”

  • A part runs out mid-job, and the work stops while someone rushes an order.
  • Some items pile up for months while others keep running short. Stock that just sits there is cash you cannot use, and it costs money to hold.
  • Reorders come down to a quick count and what happened last time. When that person is away, or demand shifts, the guess goes wrong.

How Janka works

AI does the maths. A person approves the order.

  • It reads what you actually use

    Janka works from real consumption, item by item, not just what was ordered. It does not depend on extra manual stock counts to stay current.

  • It works out when, and how much

    It forecasts what each item will need next, including seasonal and trend shifts, sets reorder points and safety stock, and shows the reasoning behind each number.

  • It drafts the order. A person approves it.

    Items heading for a stockout are flagged early, with purchase orders drafted and grouped by supplier. Nothing goes to a supplier until a person approves it.

AI does the maths. A person approves the order. Janka reads what your plant actually uses and works out when to reorder, and how much. It sets reorder points and safety stock and flags stockouts early, then drafts purchase orders grouped by supplier. The drafts wait for a person, who reviews, approves or overrides; only then does the order go. The path where an order is sent automatically is crossed out: never sent automatically.

What Janka shows you

One view of the stock that finance and operations can both work from.

  • Days of stock left

    How long each item will last at the rate it is really being used, with the ones trending to a stockout flagged before they run out.

  • Capital tied up in stock

    How much money is sitting on the shelves, and which stock is earning its keep and which is just sitting there, marked for review.

  • Forecasts that keep up

    Janka needs a few weeks to a couple of months of history to find a real pattern. Items that move often are ready sooner, and the numbers adjust as the pattern changes.

Where Janka came from

A REKA build that proved repeatable.

Janka began as a client build at REKA: an inventory and capital intelligence platform for manufacturing operations. It proved repeatable, and it is now one of AntaraX’s main products, alongside Yara and PLExyz Grid. AntaraX’s own story traces the idea further back, to forecasting in REKA’s 2016 self-driving car: the car’s planner predicted seconds ahead, and Janka forecasts stock weeks ahead.

  • 2016Forecasting on the road. REKA’s self-driving car planned seconds ahead, the idea AntaraX’s story says became Janka.
  • Client buildBuilt for a manufacturing operation. An inventory and capital intelligence platform, engineered by REKA through Custom Build & R&D.
  • 2026An AntaraX product. AntaraX launches on 23 July 2026, with Yara, Janka and PLExyz Grid.

Janka, from AntaraX

Janka came from REKA’s work and is an AntaraX product. You get it from AntaraX, at antarax.ai.

REKA explores, researches and engineers; AntaraX productises, deploys and scales what proves repeatable. REKA does not sell Janka. If your stock problem needs something no product covers yet, talk to REKA.
