Contra Free — Devil’s Advocate for Writers

Contra — Devil's Advocate writing review extension

Publish nothing your harshest reader hasn't already attacked. Every writer has the same blind spot: their own argument. Contra Free is a devil's advocate that lives in your browser's side panel. Select any text — a blog draft, a tweet, a product announcement, an opinion piece — and adversarial AI editors review it in real time, streaming structured findings into color-coded cards. ⚔ HOSTILE REVIEWER — where your argument breaks. A red-team critic hunts your 3 most lethal logical breakpoints: logical gaps, unsupported claims, weak evidence, and the exact sentence a hostile reader would quote against you — each severity-rated so you know what to fix first. 🔍 BLIND-SPOT HUNTER — what you never considered. A second engine runs in parallel, looking for what's absent: missing stakeholders, unexamined assumptions, and the counter-example you didn't see coming. 🛡 STEEL-MAN REWRITER — come back stronger. Findings become fixes: weak passages rewritten to withstand the strongest counter-argument. BUILT FOR THE WAY YOU WRITE • 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 • Compare revisions: re-review after edits and see what got fixed • Custom focus: tell the editors what to scrutinize • Editor severity slider: gentle, standard, or savage • Multimodal: analyze embedded charts & figures (vision-capable models) • Export reviews as .txt reports or shareable red-pen image cards • Local history of your past 20 reviews • 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 — seven 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. FREE, COMPLETELY Contra Free ships fully unlocked: all three editor cores, all seven providers, no daily cap, no account, no card, no trial clock — and zero payment UI inside the extension. A single "full version" link points to the project page for news about the upcoming paid edition. Stop shipping arguments that fold at the first hostile comment. Run them through Contra first.Publish nothing your harshest reader hasn't already attacked. Every writer has the same blind spot: their own argument.
