Changelog

New

• Voice AI interviews (beta). The interviewer speaks its questions, you answer out loud, follow-up probes are voiced too, and the verdict appears once the AI finishes speaking. Code tasks keep the built-in editor — you can attach code to a spoken answer. Available on Pro and Premium; the free tier gets a trial session and Basic gets a voice budget within its AI credits.
• Smarter question selection in AI modes. The session plan is built server-side: unseen questions come first, failed ones resurface sooner, and nothing repeats until you have been through the whole pool. Sessions survive a page reload, and the side rail shows the full topic map with your current position.
• The Abyss Token wallet. One AI-credit balance per tier, visible right in the builder: what is left, what it covers, and when the limit resets.
• Thousands of new questions. The bank has grown severalfold: DevOps, Security, ML, System Analysis, Data Analytics, Swift, C#, Kotlin, PHP, JavaScript, TypeScript, Java, QA and Python all received full question sets, and the specialty roadmaps gained new knowledge nodes.
• Question frequency. Every question now carries a rating of how often it actually comes up in interviews — so you know what to learn first.
• Optional sections in the builder. SQL, system design, management and other cross-cutting topics can be added to a session as separate opt-in sections.
• Card payments. International card checkout for subscriptions: purchase, tier switch (upgrades apply immediately with proration, downgrades at the next period), cancel and resume — all self-service, with live prices on the pricing page.
• Payments in rubles. The Tribute channel supports all three tiers and shows up-to-date ruble prices.
• Discord community. Sign in with Discord, a private server with tier-based roles, and /bug + /feature tickets right from chat.
• Mobile navigation. A bottom navigation bar with quick access to the Knowledge base — the site is now comfortable to use from a phone.

Improved

• The interview builder was reworked: an accurate pre-start summary (topics, Text/Voice, duration estimate), tier accent colors and real domain logos.
• The question graph loads with a real progress bar and got noticeably lighter.
• The roadmap opens centered, the topic index collapses, and more topics are localized.
• Questions now have public preview pages — the material is easier to find through search.
• All AI surfaces carry an accuracy notice.

Fixed

• Reloading the page mid-grading no longer loses your answer or spends a second AI evaluation — the finished grade shows up right after restore.
• Skipping a follow-up question no longer erases an already-credited correct answer.
• A trial voice session keeps voice mode after a reload.
• Card checkout completes right in the overlay, without jumping to the account page.
• The landing page no longer flashes black when the window is resized.
