Kal means yesterday and tomorrow. I built home bakers a WhatsApp order sheet that never guesses which.

Description and use

Pakka automatically extracts orders from exported WhatsApp chats, validates details, and produces a bake sheet, keeping all data on the baker’s phone.

Problem

Home bakers take orders on WhatsApp and manually compile a bake sheet, risking mistakes such as wrong dates, weights, or eggless status.

Outcome

Pakka reduces manual notebook work, prevents mis‑orders, and keeps all data on the baker’s phone without uploading to a server.

Workflow

• Export each order chat from WhatsApp (⋮ → More → Export chat → Without media).
• Add the resulting .txt or .zip files to Pakka.
• Gemma 4 E2B runs in the browser, copies exact words for each detail.
• Code parses the output, validates against the chat, and flags uncertainties.
• Baker reviews amber notes, corrects if needed, and sends confirmation messages via the Copy confirmation button.

Evidence

Gemma 4 E2B reads each chat in your browser and Pakka builds a bake sheet grouped by day: time, customer, cake, weight, eggless or not, the message for the top, price, advance, and what's still due.

Source

Nothing is uploaded. No account, no server, no API key. Customer names, phone chats and home addresses stay on the baker's phone.

The first run downloads the model once, about 2 GB.
