speakeasyprep.ai
A working AI interview prep tool shipped to real users on a real stack — after the no-code prototype proved there was a there there.
Generic interview prep tools give you a question bank and a timer and call it a day. But the job of interview prep isn't reading questions — it's rehearsing your answers against a specific job description, hearing yourself out loud, and knowing which stories land and which ones ramble. None of the existing tools did that end-to-end. Candidates were doing the work in Google Docs, Loom, and their heads.
Ship the minimum loop on no-code first — Lovable plus n8n — to prove the workflow was worth building. The moment it was validated, throw out the prototype and rebuild the whole thing on a stack that could handle real users, real payments, and real AI latency: Next.js 16 on Vercel, Supabase for auth and data, and a multi-model AI pipeline chosen per task instead of one model for everything. The rebuild wasn't scope creep — it was the plan.
- Upload a job description — Claude Sonnet 4.5 parses it into the actual skills and stories the hiring manager will dig into
- Generate a personalized story bank from your resume — not generic STAR templates, your real experiences shaped to the role
- Gap analysis — Gemini 2.5 Flash finds the holes between what the JD wants and what your stories cover, then generates the questions you're most likely to get asked
- Voice reps — record your answer, Whisper transcribes, Claude evaluates the actual audio for specificity, rambles, and confidence
- Stripe payments — $4.99 per use or $19/month for twenty packages — no free-trial roulette, no enterprise sales motion

The story of speakeasyprep is the story every AI-curious founder should know: no-code lets you earn the right to build, but it won't carry paying users. The judgment call is knowing which week to switch — and what to keep from the prototype when you do. That judgment is what you're hiring for when you hire Barael.
