Our picks
AI Diesel Tech
Diagnose heavy-duty diesel faults
Best for: Diesel techs and owner-operators who want a guided second opinion on a fault before they turn a wrench
Strength: Enter SPN/FMI, OEM or OBD-II codes, a scanner screenshot or just the symptoms, and it walks you through tests and writes a PDF repair summary. Founded by an ASE-certified diesel tech.
Limitation: It's a web app, not a scan tool, so you still need a reader to pull codes. Every plan caps diagnoses per month, and there are no refunds.
Pricing (2026-10-19): First diagnosis free; On-Demand $12.95/mo (3 diagnoses); Quick Access $19.95/mo (10); Standard $99/mo or $79/mo billed yearly (60 diagnoses, 4 users); Pro $199/mo listed as coming soon.

OTR Diagnostics
Read codes and run regens on the truck
Best for: Owner-operators and mobile truck techs running 2008+ Cummins, Detroit, Paccar, Volvo/Mack or International engines
Strength: A Bluetooth adapter plus a phone app. Its built-in AI, OTR Assist, explains fault codes and walks you through troubleshooting, and the tool can force DPF and SCR regens and reset derates.
Limitation: Coverage is limited to those 2008+ heavy-duty engines, and the Pro membership auto-renews every year.
Pricing (2026-10-19): $399/year Pro membership (auto-renews) plus OTR Link 2 hardware, $99 with any plan; 60-day money-back guarantee.

MECH AI
Diagnose cars and light trucks
Best for: Auto techs, small shops and DIYers who want diagnosis, code lookups and wiring diagrams on a phone
Strength: Symptom diagnosis, an OBD-II decoder, repair guides, TSBs and recalls, AI wiring diagrams and photo diagnosis (MECH Vision), with plans for single techs and for shops.
Limitation: The free tier is 3 messages a day. AI answers and wiring diagrams are a starting point; confirm against OEM service info before you cut or replace anything.
Pricing (2026-10-19): Free (3 messages/day); DIY $7.99/mo; MECHANIC $19.99/mo ($14/mo yearly); AUTOSHOP $59.99/mo ($41.67/mo yearly); Shop Manager is a pilot priced per shop.

Jobber Receptionist
Answer calls and book jobs
Best for: HVAC, plumbing, electrical and other service shops on Jobber that miss calls while they are on a job
Strength: An AI receptionist that answers calls and texts and books jobs straight onto your Jobber calendar.
Limitation: It's an add-on for Jobber users, not a standalone app, and Jobber's own help pages disagree on how many conversations are included (30 vs. 100).
Pricing (2026-10-19): $29/mo add-on with 30 conversations, then $0.79 per extra conversation; unlimited on the Plus plan ($499/mo monthly or $280/mo billed annually, 5 users).

Hover
Measure roofs and exteriors from photos
Best for: Roofers, siding and exterior remodelers who want measurements and a quote from the driveway
Strength: Builds a 3D model and measurements of roofs, siding, gutters, windows and interiors from smartphone photos, plus design mockups, estimates and proposals.
Limitation: The Starter plan charges per scan, so a busy crew pays every project; the annual plans only make sense at volume.
Pricing (2026-10-19): Starter pay-per-project, first 3 projects free; full exterior scans $59 simple, $99 average, $139 complex; roof scans from $29; Pro $999/yr ($20 off every project); Business $2,999/yr; Enterprise custom.

Drawer AI
Electrical takeoff from plans
Best for: Electrical contractors bidding commercial work from PDF plans
Strength: Electrical-only AI takeoff: detects symbols and tags, groups devices by circuit using panel schedules, simulates conduit routes, sizes wire and calculates voltage drop.
Limitation: No public price. Both tiers are contact-sales, so it's built for estimating teams, not a one-truck shop.
Pricing (2026-10-19): Not published: Starter and Enterprise are both "Contact sales".

Why we start with mechanics
Other trade directories cover home services and construction. We didn't find one that ranks AI tools for mechanics, diesel and truck repair, so that's where we start, then electricians and the rest of the trades.
Drive for a living? Fuel, MPG, parking and charging for trucks are on our Transportation page.
Prices as each vendor published them on 2026-10-19. Several tools here are contact-sales; we say so instead of guessing.
