Changelog

What shipped recently

Public log of what's changed on PrepOS. Weekly cadence, no marketing fluff. Newest at the top.

First-time setup wizard · 2026-05

  • Click Start practicing on a fresh browser and you're now greeted by a 30-second setup wizard instead of a complex sidebar.
  • Quick-start presets — New grad APM, Senior PM at FAANG, AI PM at Anthropic, PM-T at Stripe — pre-fill your level, company style, and experience in one tap.
  • Pick your weakest concepts as chips so the practice queue surfaces those reps first.
  • Your settings save on this device. Next visit lands you straight in practice with everything restored.
  • A Recalibrate link in the practice sidebar lets you re-open the wizard anytime.

AI PM track is Pro Pack early-access · 2026-05

  • Pick AI PM as your target level and you'll see a focused pitch for the upcoming AI PM question bank — eval design, hallucination mitigation, cost / latency trade-offs, human-fallback design.
  • Drop your email to be first in line when the AI PM bundle ships.

Voice mock simulator: pick Claude or ChatGPT · 2026-05

  • The voice mock now supports both Anthropic Claude and OpenAI ChatGPT — pick whichever you have a key for.
  • Cleaner two-step setup: choose the model + optional add-ons (lifelike voice via ElevenLabs, or real-video Teams-style simulation), then enter just the keys you need.
  • Pro Pack option in the simulator lets you sign up for managed keys so you can skip the BYO step entirely when it ships.

Pro Pack early-access · 2026-05

  • Pro Pack — coming soon: AI PM interview questions, extra question banks, an expert-answer library, and premium interviewer personas.
  • Sign up via the email cards on the landing page, in the practice sidebar, or inside the voice-mock simulator.

Calibration polish · 2026-05

  • Experience snapshot now updates automatically when you change your target level — no more 'PM with 3-5 years' showing up for an APM candidate.
  • Custom text you've typed in any field survives level switches.
  • The Drill Room answer field is now clearly visible in dark mode (used to be black-on-black).

Mobile-friendly practice surface · 2026-05

  • /app reflows cleanly on phones — calibration sidebar, drill room, and adaptive queue all work without horizontal scrolling.
  • No more iOS auto-zoom when you tap a text input.

Privacy / Terms / About / Changelog pages · 2026-05

  • Plain-English Privacy and Terms pages document exactly what PrepOS sees and what it doesn't (almost everything stays in your browser).
  • About page tells the founder story honestly.
  • Changelog (this page) shows what's shipped recently.

Hero polish + landing redesign · 2026-05

  • Animated underline on the words 'next' and 'answer' in the headline.
  • Single primary call-to-action — Start practicing — instead of competing buttons.
  • Cleaner social-share preview when you paste pmprepos.com into LinkedIn / Slack / X.

Multi-select 'weakest areas' chips · 2026-05

  • The 'Current weakest area' free-text field is now a multi-select of all 18 PM interview concepts, grouped by round (product sense, execution, AI judgment, behavioral, strategy, technical).
  • The adaptive queue gives drills that test your chosen concepts a higher priority.
