## Title

> I built an adaptive AWS prep tool with Claude — would love AWS-cert vets to break it

## Body

I'm Charles, the founder of AccelaStudy AI. Launched the web app on Tuesday. Posting here because this subreddit is exactly the audience I built for, and I'd rather hear honest pushback now than reviews after a month of buyers.

Quick context: I'm a solo founder. The whole platform — engine, content corpus, native apps, the lot — was built in 81 days, working with Anthropic's Claude as my only collaborator. 74 repos, 1.27 million lines, 24,800+ tests, $0 raised. I mention this because it's relevant to the next paragraph.

What's actually different about it for AWS-cert candidates:

**Root-cause gap detection.** Most prep tools mark a question wrong and move on. AccelaStudy traces the failure back through a knowledge graph to the actual prerequisite gap. I keep using the example of VPC peering — when learners fail VPC peering questions, the engine almost always traces it to a gap in IP subnetting or routing-table fundamentals. So instead of "you're 60% on networking" you get a specific four-minute lesson on the underlying concept that's actually broken. This is the part I most want pushback on — does this match how you actually study, or am I solving a problem you don't have?

**Pass-probability prediction.** probabilistic simulation of 2,000 exam attempts with confidence bands, so you know when to actually book the exam. Built this because I personally hated burning $300 vouchers on coin flips.

**Cross-domain transfer.** Already passed CCP? When you start SAA-C03, the engine credits you for ~60% of overlapping foundations automatically. So you're not re-quizzed on what you already proved.

**Coverage:** All current AWS certs (CLF, SAA, DVA, SOA, SAP, DOP, ANS, SCS, MLS, MLA, AIF, AIP, DEA), 2196 hands-on console-simulator labs total (290 are AWS-specific, all strict-pass — meaning they actually drive the simulated AWS console DOM, not just video demos).

**Pricing:** $39/mo for everything across all 929 certs. Not per-cert.

What I'd love from this thread:

1. **Try the free demo** (accelastudy.ai, no signup). Tell me where the engine is wrong. If it diagnoses you with a "gap" you don't actually have, I want to know.
2. **What AWS-cert tools have you used that actually worked?** I want to be specific about how AccelaStudy is different from each of them, not just claim "it's better."
3. **What's a question type you've never seen handled well?** I built 20+ different activity formats and I'm sure there are gaps.

I'll be in this thread answering for 8+ hours today. Post anything. AMA.

## First comment (post yourself within 5 min)

> Mod note (just in case): not running ads, not asking for upvotes, won't link to a paid signup page in this thread. Just want feedback. If a mod wants to flag the post for self-promo, totally fair — I'll add a [SP] tag or whatever the sub wants.

## Second comment (after first technical reply, drops the link)

> For anyone who wants to try without an account: accelastudy.ai
>
> Pick AWS Solutions Architect Associate from the demo dropdown — that's the most-tested domain we have, so the engine is sharpest there.

## Engagement strategy

- **Be ready for the "is this just AI slop?" challenge.** Have a specific technical answer ready: the validation pipeline (entailment + adversarial-model, 90-96% pass rates per domain), the human review on every domain spec, etc.
- **Don't dismiss competitors by name.** If someone says "isn't this just Tutorials Dojo with extra steps?" — engage substantively, name one specific architectural difference, don't trash-talk.
- **Offer free month codes** to vets who passed AWS exams recently. Building credibility through the people who actually know.
