thita.ai
One AI platform for the entire engineering interview
Stop stitching together LeetCode, YouTube, Notion, and Pramp. Thita.ai is one AI platform: 99 DSA patterns, voice AI mock interviews, an AI coach, system design prep, and resume tools. Built for engineers targeting top companies, from new grad to senior. 25000+ learners
We built thita.ai because we lived the problem. Preparing for engineering interviews meant LeetCode in one tab, YouTube in another, Notion for notes, ChatGPT for explanations, and Pramp for mocks. Five tools, zero coherence, and most of the time spent on logistics instead of actual reps.
Thita is one platform built around a single idea: interviews are won by structure. We mapped 99 DSA patterns that cover roughly 95% of coding rounds, then wrapped them with a voice AI interviewer, a 1:1 AI coach that teaches with diagrams, system design tracks, and resume tools. Concept to pattern to mock to offer, all in one place.
The feature I am most attached to is AI coach with feynman Style. You explain the core insight of a problem out loud, and an AI judge scores your articulation. It catches the gap between solving a problem and understanding it, which is exactly the gap interviewers probe.
We are the team behind Repowise. Thita has grown to 25,000 engineers across 50+ countries with zero paid acquisition, mostly off a DSA patterns sheet that reached over 1M+ people organically.
Today we are opening it to the Product Hunt community. Run a mock interview or just learn through patterns. We read every comment and ship fast.
Amazing product!!! Have used this myself to cover topics of system design and dsa. And honestly love the mock interview tool as well, helped me practice interviews so I could perform better in the real one!!!
What’s the one feature people stick around for the most, patterns, the coach, or the voice interviews?
Just started using the platform and honestly, I am amazed by how native the experience feels to me. I completely relate to the problem of managing stuff at multiple places during interview preparation and most of the times I end up keeping multiple tabs open which is definitely a clutter-filled way of doing things.
Good luck to the team building it and super excited to keep following this to see it going higher-further-faster :D
@swatiahuja Tried a quick look - the experience feels smoother than I expected. Curious to see where this goes
Maker here. Built this with Swati over the last year.
The voice interviewer took the longest to get right. Early versions felt like reading off a script. We rebuilt the turn-taking so it interrupts you, pushes on weak answers, and picks the next question based on what you just said. It finally feels like a real loop.
The feature I keep coming back to is the Feynman coach. You explain the core insight out loud before writing any code, and a judge scores your articulation. People who do this before mocks explain cleaner under pressure. That gap between solving a problem and explaining it is where most onsites get lost.
We ship daily. If the voice lags, a pattern is missing, or you want a track we don't have, drop it here. We read every comment and fix fast.
Best way to judge it: start a mock cold and see how far the interviewer pushes you.
