Contra Pro — Platform Dress Rehearsal

Publish nothing the platform hasn't already rehearsed. You know the feeling: the piece is polished, the argument is tight — and then the platform eats it alive. Downvoted as spam. Ignored in the feed. A paid-wall conversion rate of zero. Contra Pro is a dress rehearsal for your writing: pick your target from the five biggest publishing venues — newsletter platforms, long-form magazines, micro-feeds, short-video apps, and forum communities — and before you publish, it shows you how that audience will receive your piece, and how to fix it. 🎯 PLATFORM DRESS REHEARSAL — see your post's fate before you post it. Two engines run against your draft: • A platform-fit review: a 0–100 score with a one-line verdict ("will earn, but reads like an ad"), plus a concrete checklist of how this venue will trip you and how to fix each issue — paywall placement and conversion hooks for newsletters, curation fit for long-form magazines, thread pacing for micro-feeds, the first-three-seconds hook for short video, self-promo red lines for forum communities. • A community simulation: 5–8 replies written the way that venue actually talks — upvoted long-takes and disaster warnings, subscriber comments and unsubscribe reasons, quote-post chains, rapid-fire comment streams. Not generic praise: the exact objections your real audience will raise. • Multi-venue & multi-round: rehearse several venues at once, up to 3 independent rounds each, with results streaming in progressively, plus an optional mechanical consensus report (score spread, shared issues, comment stability) — computed locally, no extra model calls. ⚔ GENERAL MODE — the full adversarial newsroom, free forever. • Hostile Reviewer: hunts your most lethal logical breakpoints — gaps, unsupported claims, the exact sentence a hostile reader would quote against you. • Blind-Spot Hunter: what's absent — missing stakeholders, unexamined assumptions, the counter-example you didn't see coming. • Steel-Man Rewriter: weak passages rewritten to withstand the strongest counter-argument. BUILT FOR THE WAY YOU PUBLISH • Read the full article with one click, or select text and right-click • Stage-by-stage progress with per-core timers — no dead-screen waiting • Follow-up chat with the editors: ask them to expand any finding • Export reviews as .txt reports or shareable red-pen image cards • Local history of your past reviews, per mode • English & 中文 UI; dark theme included PRIVATE BY ARCHITECTURE, NOT BY PROMISE • BYOK (bring your own key): the extension connects directly to the AI provider of your choice — ten major providers supported, domestic and international. There is no Contra server: your text goes straight from your browser to the provider you selected, under your own account. • Keys are AES-GCM encrypted on your device, with an optional passphrase vault. • Zero telemetry. No analytics, no tracking, no accounts. • One-click revoke wipes all local secrets.
