Superday AI vs IB Vine (2026)

Our honest IB Vine review and head-to-head comparison: one of the biggest banks of reported interview questions against an all-in-one AI practice platform, and what the full stack really costs on each.

Last updated · Competitor facts checked against their public pages

The Short Version

IB Vine's edge is inventory: 2,140+ technical questions, most reported from real interviews and organized by bank, with a real free tier. Superday AI's edge is the feedback loop: AI grading on every answer, unlimited mock interviews, resume review, and networking tools in one $12 a month plan. On IB Vine, AI mock interviews are a separate pay-per-minute product and behavioral prep requires the $50 a month tier. If you mainly want questions to read, IB Vine is solid. If you want to be tested and coached, Superday AI does that out of the box.

Their full stack runs $50 a month plus metered mocks. Everything here is $12, and the first 5 days are free.

IB Vine has earned its reputation the slow way. It started in late 2019 as a student side project, relaunched in early 2025 as IB Vine 2.0, and grew into one of the larger banks of real reported interview questions in IB prep, with per-bank counts published right on the site.

Superday AI plays a different game. The question bank matters, but the product is the loop around it: answer, get graded, see the gap, fix it, repeat. Mock interviews, coaching, resume review, and networking tools are all part of the same subscription instead of separate purchases.

The two overlap more than either does with a forum or a modeling course, so the details matter. This review covers how the tiers, the AI, and the pricing actually compare as of July 2026.

What Is IB Vine?

IB Vine (ibvine.io) is a question-bank-first prep platform started in late 2019 as a college side project and rebuilt from scratch by the same founder in early 2025 as IB Vine 2.0. It is a technical founder's product, built and run solo by an engineer rather than by former bankers, which shows in both the clean execution and the narrow scope. Its core asset is scale of real questions: 2,140+ technical questions, including 1,720+ reported from interviews across 55+ banks, plus 380+ behavioral questions, 40 learning modules, 20+ hours of podcasts, and a library of 90+ pre-recorded mock interview recordings.

Pricing runs from a free technicals tier to Pro at $30 a month (all technical collections) to Diamond at $50 a month (adds behavioral questions, modules, and the mock library), with cheaper 6-month and annual billing. AI voice mock interviews live in a separate companion product called IB Mock, sold as pay-per-minute credit packs, with discounts and some free minutes for paid IB Vine members.

Where It Shines

  • One of the largest reported-question inventories in IB prep, with per-bank counts published
  • A real free tier: 283 fundamentals questions at no cost
  • Multi-format study: learning modules, flashcards, podcasts, and audio playback
  • Real traction: the site reports 200K+ students and publishes an outcomes wall of offers by school and firm
  • Voice AI mock interviews available through its IB Mock companion product

Where It Falls Short

  • AI is not part of the subscription: IB Mock interviews are billed per minute on top of Pro or Diamond
  • Behavioral questions, learning modules, and the mock library all require the $50 a month Diamond tier
  • The mock interview library is pre-recorded audio to listen to, not interactive practice
  • No resume review, networking tools, coaching chat, or mobile app
  • Built by a technical founder, not former bankers: there is no banker-written rubric or grading layer behind the questions
  • No refunds, stated plainly in their FAQ (there is a 3-day trial)

What Is Superday AI?

Superday AI is an AI prep platform built specifically for investment banking recruiting, built by ex-bankers and PE investors. The core idea: you get good at interviews by doing them, not by reading about them. So everything centers on practice with feedback: 1,500+ drill questions graded instantly against banker-written rubrics, unlimited mock interviews that adapt to your level and target firms, and an AI coach that knows your resume, your progress, and where you are weak.

It also covers the rest of the recruiting process. You get an AI resume review scored against real IB hiring criteria, a networking CRM with a Chrome extension that saves LinkedIn contacts in one click, target firm tracking, audio guides, an AI whiteboard for technical walkthroughs, and SIE exam prep. Plans start at $12 a month with a 5-day free trial, and there is an $85 lifetime option.

The Detailed Breakdown

Question banks and where they come from

IB Vine

IB Vine's inventory is its moat: 2,140+ technical and 380+ behavioral questions tagged by bank, including 1,720+ reported from real interviews across 55+ banks, with counts you can check per firm. For volume of raw questions to work through, especially harder off-guide technicals, it is one of the strongest options anywhere. The caveat: it is an engineer's solo project, so while the questions come from real interviews, the material around them is not written or graded by career bankers.

Superday AI

Superday AI's bank is smaller by raw count but built for grading: 1,500+ drills, each with a banker-written rubric so the AI can score your answer instead of just showing you a model one. A verified question bank adds questions submitted from recent real interviews, and free interview guides cover 45+ banks.

Bottom line: If your prep style is grinding through maximum question volume, IB Vine's inventory is excellent. If you want every question to come with a grade and a fix, that is the Superday AI design.

What practice actually looks like

IB Vine

On IB Vine you read questions, flip flashcards, take module quizzes, and listen to recorded mock interviews. It is well organized self-study. The interactive part, voice AI mocks through IB Mock, is a separate product billed by the minute, with credit packs from an $18 intro hour up to $365 for twelve hours.

Superday AI

On Superday AI practice is the product: type or speak answers and get rubric-based grades instantly, run unlimited mock interviews that adapt to your level and follow up on weak answers, and work paper LBOs on the AI whiteboard. Nothing is metered; there is no per-minute anything.

Bottom line: Metered AI changes how you practice: every mock has a cost attached. Unlimited practice removes that hesitation, and hesitation is the enemy of reps.

Coverage beyond questions

IB Vine

IB Vine stays close to its lane: questions, modules, podcasts, and an outcomes board. There is no resume tool, no networking tracker, no coaching chat, and no job-search workflow. What it does, it does with focus.

Superday AI

Superday AI covers the whole process: AI resume review scored on IB hiring criteria, a networking CRM with a Chrome extension and AI email drafter, target firm tracking with application statuses, SIE exam prep, audio guides, and an iOS app.

Bottom line: If you only need question practice, the extra coverage may not matter to you. If you are running a full recruiting process, having it in one place is the point.

Pricing

IB Vine

IB Vine's free tier is real, and Pro at $30 a month (or $210 a year) is fair for technicals-only volume. The full experience costs more: Diamond is $50 a month or $350 a year, and live AI mocks are extra through IB Mock credit packs. There are no refunds, though the 3-day trial helps.

Superday AI

Superday AI has one feature set at every price: $12 a month, $30 a quarter, or $85 once for lifetime access, after a 5-day free trial. Drills, unlimited mocks, coaching, resume review, and networking tools are all in the base price.

Bottom line: Getting the equivalent of Superday AI's bundle on IB Vine means Diamond plus mock credits, which runs multiples of $12 a month. Compare the tiers you would actually buy.

Frequently Asked Questions

Is IB Vine good for investment banking interview prep?

Yes, for what it is: one of the biggest banks of real reported interview questions, organized by firm, with solid study formats like flashcards and podcasts. Where it is thin is feedback: grading is self-assessed, live AI mocks cost extra through its IB Mock companion product, and there are no resume or networking tools.

Is IB Vine free?

Partly. The Basic tier is genuinely free: 283 fundamentals questions, access to 1 of 93 mock library sessions, and 7 of 40 learning modules. The full technical collections require Pro at $30 a month, and behavioral questions plus the full mock library require Diamond at $50 a month, with a 3-day Diamond trial available. Superday AI prices differently: one $12 a month plan with everything included, after a 5-day free trial.

Is IB Vine worth it?

For raw technical volume, yes: 2,140+ technicals with per-bank counts is one of the largest reported-question inventories available, and the free tier lets you judge the format before paying anything. Price the full experience honestly, though: technicals-only Pro is $30 a month, behavioral prep needs the $50 a month Diamond tier, and live AI mock interviews are billed separately per minute through IB Mock. If your bottleneck is feedback rather than volume, a platform that grades every answer and includes unlimited mocks may serve you better per dollar.

What is the difference between Superday AI and IB Vine?

IB Vine is a question bank with study content around it. Superday AI is a practice platform: every drill is graded by AI against a banker-written rubric, mock interviews are unlimited and interactive, and the subscription includes coaching, resume review, and networking tools. IB Vine sells its AI mocks separately by the minute.

How much does IB Vine cost compared to Superday AI?

IB Vine is free for 283 fundamentals questions, $30 a month for Pro (technicals only), and $50 a month for Diamond (behavioral, modules, mock library), with cheaper annual billing and no refunds. AI mocks through IB Mock cost extra, from an $18 intro pack to $365 for twelve hours. Superday AI is $12 a month or $85 lifetime with everything included and a 5-day free trial.

Does IB Vine have AI mock interviews?

Not inside the subscription. IB Vine's mock interview library is pre-recorded audio sessions. Its companion product IB Mock offers voice AI interviews billed through per-minute credit packs, with discounts for paid IB Vine members. Superday AI includes unlimited interactive mock interviews in every plan.

Who runs IB Vine?

IB Vine started in late 2019 as a college side project and was rebuilt from scratch by the same founder in 2025. It is run as effectively a one-person operation by a technical founder, which is genuinely impressive execution, but it is a different foundation than a team of former bankers writing and grading interview content. Superday AI is built by ex-bankers and PE investors.
