What is Lumi?
Kapi Bookkeeping (Lumi) is an AI bookkeeping app launched by SenseTime. The official keeps the input cost of bookkeeping itself very low: take a photo of a receipt or say a sentence, and the AI fills in the amount, merchant and consumption type, with users only needing to confirm. Compared with traditional bookkeeping tools that require selecting categories item by item, it is more suitable for ordinary users who start and give up repeatedly, as the time for single-bookkeeping is compressed to a few seconds.
Who is it for?
- People who want to start keeping accounts but always give up by the third week: Using photo-taking and voice input reduces the time for single-entry bookkeeping to a few seconds, making it easier to stick to than manually selecting categories.
- People who need to manage joint household expenses: Use separate ledgers to distinguish daily expenses from special expenditures, so you don't have to scroll through chat records when reconciling accounts at the end of the month.
- Business travelers who are often on the road: Take a quick photo of travel expense receipts and save them to the ledger, then sort out the reimbursement documents and amounts in a unified manner after returning from the trip.
- Young people who want to review their consumption structure: See the items with the highest category proportions first, and then decide which category to start cutting back on.
- Students: Only track three categories of expenses—food, transportation, and study—and set a clear monthly spending limit.
Key features
6Receipt Photo Bookkeeping
Take a photo of a receipt, bill screenshot or payment page, and the AI will automatically identify the amount and merchant and generate a record. The official stated purpose is to eliminate the need for users to manually enter numbers.
Voice Accounting
Say the expense details and amount in one sentence, and the system automatically breaks them down into structured accounts, eliminating the most easily abandoned steps of selecting categories, accounts, and dates.
Automatic Categorization
The AI judges the consumption type based on the merchant name and text description. The official description states that you can form a statistical expenditure structure without manually adding tags.
Bills and Budgeting
Summarize expenses by week and month, view the proportion and trend changes of each category, help users find overspending items and adjust the monthly budget in a timely manner.
Multi-book Management
Supports creating different ledgers and accounts to record daily expenses, travel costs, or joint family expenses separately, preventing all transaction records from being mixed together.
Chart Review
Presents the composition and changes of consumption in the form of charts, which, according to the official, allows users to more intuitively see their spending habits and structures.
How to use Lumi
- 1Narrow down the scope first: Only record expenses exceeding a certain amount or just one category, and stick to this for two weeks before expanding to all income and expenses.
- 2After taking a photo for recognition, check the amount and merchant. AI may easily misclassify blurry receipts or combined payments, and one mistake can contaminate subsequent statistical results.
- 3Create separate tags for fixed expenses, such as rent, insurance, and subscription services, to make it easy to check later whether a certain subscription is still charging continuously.
- 4Your bookkeeping data involves consumption privacy. Prioritize products with local storage or clear data usage disclosures, and do not casually export it to public channels.
- 5Treat AI bookkeeping as a digital summarization tool rather than financial advice; you should still make your own judgments on budgeting and investment decisions.
