AI the right way.

Every AI has blind spots. 1K4 catches them.

Five named advisors review your code, plans, and decisions in parallel and surface where they disagree. That's Quorum, the 1K4 peer-review layer for Claude Code, Codex, Cursor, terminal, or 1K4 Agent Lab.

Setup is free. Cloud reviews run on prepaid credits with a per-run cap.

Two review tools, one layer: Quorum for open-ended questions. 1k4-review for plan-mode checks before file changes.

Paste it to your coding agent, or run it in your terminal.

Installs 1K4, or safely repairs an existing setup — fine to re-run.

This is what a Quorum review looks like.

Three example advisors from Quorum's five. Switch tabs to compare how each output shape differs on a real prompt.

You: Use the Code Auditor on backend/auth/middleware.py. Worried about session fixation.

Critical

Session ID not regenerated post-login. An attacker who plants a known session ID before login retains access after authentication. Evidence: middleware.py:47 (set_user_id updates payload but never calls session.regenerate_id()).

Important

No CSRF token check on state-changing routes. Logout and password-change handlers accept POST without verifying a CSRF token. Evidence: middleware.py:71-86.

Advisory

Open redirect via next query param. Post-login redirect honors any URL passed in ?next=. Evidence: middleware.py:102; add ALLOWED_HOSTS check.

How peer review works

Independent answers, then disagreement, then a decision you can act on.

Ask

Send a plan, a question, or a decision. One model would just answer.

Separate

Multiple models respond independently. No copying, no echo chamber.

Challenge

The models review each other. Disagreement is surfaced, not hidden.

Decide

You get consensus, dissent, and a recommended next step. Use it where you work.

Multi-model review is a pressure-test, not a guarantee. Models can share blind spots. We surface disagreement so you can judge.

Use it where the work happens

Three lanes, one workflow.

For Claude Code and Codex users

Review a plan before you implement it.

Hand Claude Code's plan to other models before any files change. Catch missing migrations, missed edge cases, security gaps. Promo lives on the Plan Reviewer page.

For architects and operators

Ask Quorum a hard question.

Five named specialists: Code Auditor, Research, Analysis, Counterpoint, Budget. Ask one. Or run a brainstorm and watch them argue.

When work grows

Continue the review in Lab.

Files, sessions, diffs, deploys, multi-turn agent work. Lab is the workspace when one review isn't the whole job.

Inside 1K4 Lab

The workspace where review turns into work.

Peer review gets you to a decision. Lab is where that decision turns into files, revisions, deploys, and follow-up work in the same project.

START WITH DIRECTION

Brainstorm and review in one place.

Turn a rough brief into a structured plan, then pressure-test it before work begins.

Brainstorm + Review

MOVE INTO ARTIFACTS

Build outputs you can inspect.

Create mockups, revise documents, and generate code in a workspace that keeps edits visible.

Build

SHIP FROM CONTEXT

Deploy from the same session.

Provision, build, and publish without losing the thread that produced the decision.

Deploy

KEEP WORK MOVING

Automate the handoffs.

Track queued tasks, watch progress, and step in only when the agent needs a decision.

Automate

CONNECT THE REST OF 1K4

Code, models, and apps stay attached.

Move from Lab into code review, model routing, and connected apps without changing projects.

Tour Lab

Public tour. The member workspace opens after setup.

Pricing

Free setup. Capped cloud reviews.

Connect local models for $0. Cloud reviewers run on prepaid credits, with a per-run cap before anything starts.

FREE

Your own models

Connect your local Ollama via the 1K4 Bridge. Full agent capability on your hardware. Performance depends on your model.

CLOUD

Cloud models

$1 = 1 credit

Buy credits. Use any model from any provider. Per token, per image, per second. No overage. No expiry. Set a per-run cap so a single Quorum or review cannot overspend. Typical Quorum runs cost $0.10 to $2.00.
