Inviting beta testers for our Product Brain that stops Context Drift in AI Coding Agents

I’ve been vibe‑coding with Cursor, Lovable, and Claude Code for a while. They crush one‑shot tasks, but at feature 5–10 everything starts to drift. The AI forgets past decisions, breaks old logic, and I end up cleaning up “slop” instead of shipping.

The real problem isn’t the code, it’s Product Definition. As you stack features, the soul of the product gets lost. Agents don’t have a single, authoritative spec to obey.

So we’re building ReviewMyProduct – an authoritative Product OS that sits above your AI coding tools and tells them exactly what to build and why.

What it does:

• Multimodal ingestion: Dump links, docs, audio, video. We parse it into an internal model of your product’s entities, flows, and constraints.
• Depth checks: Frame‑level video + cross‑checking so your spoken walkthrough can’t silently contradict your written docs.
• Fallacy detection: We stress‑test your product structure to find logical holes before you write code.
• Interrogation on new features: Every new feature is checked against that model to surface conflicts (e.g. “Guest checkout” vs “Loyalty points that require an account”) and force a decision before an agent blindly builds both.
• Execution: Once the logic is consistent, we feed strict, conflict‑free context to your coding agent (Cursor, Claude Code, etc.).

Why this matters:

• Less drift and rework: Every time an agent drifts, you pay in refactors and lost trust.
• Fewer wasted tokens: Long, vague prompts are expensive. A tight Product Index means shorter conversations and fewer retries.

Who this is for:

• PMs who want truly “engineer‑ready” PRDs without spending days polishing specs.
• Solopreneurs / small teams who want a single “context dump” so agents stop guessing and start following a clear product brain.

Right now we’re dogfooding this on our own stack (including our landing page) and starting a small beta. If you’re heavily using Cursor / Claude Code and feel the pain of context drift, signup for the beta testing group.
