Hey Product Hunt 👋

I built Zagens because I kept hitting the same loop: the agent writes code confidently, I find a hallucinated function name three files deep, and suddenly I'm spending an hour auditing everything it touched. It didn't mean to break things — it just has no way to verify its own work.

The problem isn't model IQ. We dropped superhuman autocomplete into an engineering workflow with no code review, no CI, no "are we actually done?" — just tokens and on to the next turn.

So instead of waiting for a smarter model, I built the engineering layer around it — a Windows harness, not prettier chat bubbles:

Multi-agent pipeline — explore (read-only), implement, review; failed review loops back automatically

Verification gates — builds, tests, and grep weigh in before a step is marked done

Long-session discipline — checklist, auto-continue, turn-by-turn replay so work doesn't quietly drift

I also merged Office (Excel, Word, PowerPoint, PDF) into the same app — I was tired of switching between AI and document tools.

If you've wrestled with agents that sound confident but ship broken code — what verification patterns have you wired into your own workflow? Would love to hear it. 🙏
