Every business mile, logged the day it happened.
Tell Grain AI about a trip, "45 miles to the Henderson kitchen and back", and the mileage gets logged with the right job, the right date, and the right purpose. The mobile auto-tracker lands with the native apps in Q3 2026.
How mileage logging works today
Open Grain AI chat (typed or voice). Describe the trip in plain language: from-where, to-where, miles, and which job it was for. The AI logs the trip with the standard IRS-mileage fields and links it to the right job's P&L.
Trips are editable after the fact, fix the date, attach a different job, adjust the miles. Every trip carries a per-mile rate so the deduction value rolls up cleanly at year-end.
- Log a trip by talking or typing in Grain AI chat, same flow as receipt logging.
- Auto-extracted: from/to, miles, date, purpose.
- Linked to a job, feeds per-job P&L.
- IRS-standard fields for tax-deduction reporting.
- Editable after the fact for typo fixes or job re-attribution.
The mobile auto-tracker (Q3 2026)
When the native iOS and Android apps ship in Q3 2026, the mobile mileage tracker turns on. It runs in the background, detects when the truck starts moving, captures the route, and asks one question at the end: "Which job was that for?"
The auto-tracker is the difference between "I think I drove ~40 miles to that job" and "I drove 38.7 miles to that job, here's the route." Until then, chat-based logging is the path; it covers the same data, it just asks you to type or talk it.
- Automatic background trip capture (lands with the iOS + Android apps Q3 2026).
- GPS-route capture for the audit trail.
- Single end-of-trip question: "Which job was that for?"
- Same data shape as today's chat-logged trips, no migration needed when the apps land.
Why log mileage at all
Vehicle mileage is one of the largest deductions a one-truck operation has. The IRS standard rate covers fuel, maintenance, depreciation, and insurance, at 67¢ per mile, an honest trade truck logs $5,000-$15,000 in deductible miles a year.
The hard part isn't claiming the deduction; it's having a record that holds up if the IRS asks. Logging trips at the time they happen, instead of guessing from memory in March, is the difference between a defensible deduction and a creative reconstruction.
Available on Pro, $29/mo.
