Smart Hub LLC is a small software company. Our products hold real spoken conversations, with aircraft mechanics and with hiring teams.
See the productsHow are current, voltage and resistance related in an electrical circuit?
Voltage is what pushes the current, and resistance works against it. That's Ohm's law, I think.
The voltage across a resistor is doubled while its resistance stays constant. What happens to the current?
From DMEReady's public sample session. The candidate is voiced by AI.
Tell me about a time a deadline slipped on one of Sarah's projects.
She owned it, told the client herself, and it didn't happen again on my watch.
You said it didn't happen again. What did she change in how she worked?
Illustrative, based on VoiceRef's sample call. The people are fictional.

To earn an FAA mechanic certificate, candidates pass an oral exam with a designated examiner. DMEReady lets them rehearse it out loud in a browser, then shows what each answer covered, what it missed, and which FAA handbook page to study.
VoiceRef's sample report, made with fictional people.
Reference checks by phone, without the phone tag. Each reference agrees by text first. Then an AI interviewer calls, asks eight questions about the candidate's work, and follows up when an answer is vague.
Both products follow the same loop. The part most tools skip is the third one.
Every question is written and checked before any call, from sources we can point to.
Speech is transcribed live, and the system waits for the person to finish rather than cutting in.
When an answer is thin or vague, the follow-up asks for the missing part, like a real examiner or interviewer would.
Afterwards, a report quotes the answers and shows what was covered and what was missing.
DMEReady only asks and grades from FAA material we have checked, and every point in a report links to the page it came from.
Our reports help someone prepare or make a call. They don't make the call for them.
DMEReady doesn't store voice recordings. Each product's privacy policy says what is kept and for how long.
We design, write and operate both products ourselves, and we answer support email ourselves too.
Smart Hub LLC is owned and run full-time by its founder, Serdar Selçuk, who works from Türkiye. The company is self-funded.
It was formed in New Mexico in 2024, started with small web projects, began building its own software products in 2025, and now concentrates on voice software.
