The problem

Manual expense approval doesn't scale

🕐

Time drain

Finance teams spend 4+ hours/week manually reviewing receipts, invoices, and expense forms line by line.

🔍

Errors slip through

Wrong dates, inflated amounts, duplicate invoices — human reviewers miss 15-20% of anomalies under time pressure.

📋

No consistency

Different approvers apply different standards. No institutional memory of past decisions or categorization rules.

How it works

Three steps. Zero setup friction.

01

Employee submits in Lark

They submit expense reports as usual in Lark. No new tools, no behavior change. Kopi monitors via webhook.

02

AI checks everything

Kopi downloads attachments, reads invoices with AI vision, cross-validates dates and amounts, categorizes each item.

03

Approver gets results

A 3-color card appears in Lark: green (auto-pass), yellow (needs confirmation), red (flagged). One tap to approve.

Features

Five-dimension AI check. Not a simple category bot.

🧾

Invoice verification

Claude AI reads your PDF/image invoices, extracts seller, amount, date, and cross-validates against the expense form.

💰

Amount anomaly detection

Flags expenses that deviate from historical patterns. S$12,000 hotel? Kopi catches it before the approver sees it.

📅

Date cross-validation

Checks if form date matches invoice date, detects future dates, and flags suspicious timing gaps.

🏷️

Smart categorization

12 preset Singapore SMB categories. AI suggests the right one with confidence scores and explanations.

🧠

Rule learning

Every time an approver confirms a category, Kopi remembers. Same expense next time? Auto-approved.

💬

Native Lark integration

Interactive cards right in Lark. Select categories, request more info, acknowledge — all without leaving the chat.

Every expense, five checks

Each line item gets a detailed check report. Approvers see exactly what passed and what didn't.

FAQ

Common questions

What is Kopi?
Kopi is an AI expense approval copilot for Lark (Feishu). It automatically checks expense reports — verifying invoices with AI vision, flagging anomalies, and learning your approval rules — so approvers get a clear green/yellow/red result card without manual review.
How does Kopi check expense approvals in Lark?
When an employee submits an expense in Lark, Kopi receives the approval via webhook, downloads attached invoices, uses Claude AI vision to extract line items, runs a 5-dimension analysis (category, amount, date, invoice, rule match), and sends an interactive check card back to the approver — all within seconds.
Is Kopi free to use?
Yes — Kopi is completely free during private beta for Singapore SMBs. No credit card required. Early users lock in founding-member pricing when paid plans launch.
What Lark approval types does Kopi support?
Kopi currently supports expense report and invoice P&L approvals in Lark. It connects to any Lark approval flow definition and can be configured to monitor specific approval types.
How long does setup take?
About 10 minutes. Connect your Lark app credentials, select which approval flows to monitor, and Kopi is live. The first AI check card appears in Lark within an hour.
