Jack is the AI mechanic, and he doesn't work from a blank page. He pulls your vehicle's VIN-decoded specs, its full service history, and your shop notes before he answers — so the answer is about your vehicle, not a hypothetical one. And when he doesn't have a verified figure for your exact configuration, he says so instead of inventing one.
Jack lite is a floating widget you can pull up mid-task from anywhere in the app — quick question, quick answer. Ask Jack PRO is the dedicated screen for the deep dive: full risk scoring, step-by-step plans, parts lists, and the detail folded underneath.
| VERDICT | The short answer first — what it probably is and whether to drive it. |
| RISK PANEL | Priority score 1–10 plus Safety, Driveability, and Long-Term bars. One risk language everywhere in the app — the same scoring shows up in DTC diagnosis and Jack's 2¢. |
| SUGGESTED STEPS | Numbered, in the order Jack would actually check them — cheapest and most likely first. |
| PARTS & DETAIL | Folded away until you want it. No wall of text unless you ask for the wall. |
| SHOP NOTE | Save any diagnosis straight into the vehicle's file for next time. |
Push-to-talk voice: one tap per question, the mic never arms itself. Long-press for a full back-and-forth session. Camera input: photograph the part, the leak, the connector you can't name, and ask about what he sees — he remembers the photo for follow-ups.
Works with cheap Bluetooth ELM327-style adapters. Live gauges, fault codes with plain-English explanations, and clearing — plus spoken alerts so your eyes stay on the road.
| DIGITAL | Big numeric readout with unit tag. The workhorse. |
| ANALOG | Needle sweep with red warn arc — tach-style. |
| BAR | 16-segment ascending equalizer; segments past the warn threshold go red. |
| HISTORY | Rolling sparkline — watch a value trend, not just its current number. |
| COMPASS | Rose face for GPS heading. |
| CLOCK | Because sometimes you just want the time on the dash. |
Drag gauges anywhere on a grid, size them small to large, spread them across multiple pages. GPS-sourced signals (speed, compass) ride alongside ECU data.
Safety-critical sensors are polled whether or not their gauge is on the current page. You can be staring at gauge page 2 and still get the coolant warning from page 1 — the gauge layout is a display preference, not the acquisition list.
Not one flat recording mode. Each quick test is engineered for what it's hunting — sample rate, duration, and trigger conditions set per diagnosis. Or build a custom log with the sensors you pick.
| WARMUP CHECK | Runs long, because warmup takes minutes — watch the whole cold-to-operating curve. |
| FUEL TRIM / AFR | Tracks the mixture — the lean-idle-clean-cruise patterns that point at real causes. |
| MISFIRE HUNT | Polls flat-out, because misfires last milliseconds. |
| COOLING SYSTEM | Watches temperature behavior for thermostat and efficiency problems. |
| HIGHWAY CRUISE | Waits until you're actually at speed before it records — no driveway noise in the data. |
Recorded runs chart in-app and can be handed to Jack for a read.
Pick your vehicle, name the part you need. Jack returns the donor list — which other vehicles, which years, carry a part that fits yours — with fitment notes on the ones that need a second look. So you know which rows to walk before you walk them.
Under the results: a follow-up chat that already knows your vehicle, your part, and the compat list — plus one-tap search links for wiring diagrams, connector pinouts, and OEM part numbers.
Every vehicle gets a file with five tabs:
| SPECS | Fluids & capacities — oil weight/capacity/type, coolant, trans, diffs, brake fluid — plus service intervals. Values are fetched, source-tagged, and editable; you always know where a number came from. |
| STATUS | Maintenance systems grouped by state, pulling last-service from your own log history. |
| LOG | Type it like a human — "changed oil, replaced radiator, new hoses, thermostat, coolant flush" — and Jack structures it into dated, mileage-stamped records. |
| JACK'S 2¢ | Unprompted: what's likely to need attention next on your platform, weighed against your miles and your history. |
| HISTORY | The full service record — date, mileage, system, type, details. |
The whole record exports — a data file for handoff, or a printable report when you sell.
The burger wrapper is retired. It served honorably.
Scan a VIN, type one, or enter year/make/model by hand. Scout pulls official NHTSA recall and complaint records for that vehicle, then adds the AI layer: known trouble spots for the platform, a pre-purchase checklist, and an honest read on value — before the cash leaves your pocket.
| THEMES | Six full color schemes — amber CRT (correct), phosphor green, daylight, blue, red, white. |
| JACK'S PERSONALITY | Slider for how Jack talks to you — and how much detail he leads with. |
| UNITS | Imperial/metric, °F/°C — respected everywhere, including gauge sub-labels. |
| VOICE ALERTS | Spoken out-of-range warnings on or off. |
