Predict Virality
Before You Post
Test thousands of audience reactions in seconds. Run your content through the Forum — a simulated audience of 10,000 digital twins — before you ship. See what resonates, what falls flat, and ship only what wins.
How It Works
Three steps from draft to Forum-cleared winner.
Upload
Drop your video, image, or hook into the Forum. Cortex Forum scores it on 5 factors: hook, pacing, emotion, clarity, CTA.
# Upload a draft to the Forum
from liquidcortex_forum import Forum
forum = Forum(api_key="lc_forum_...")
draft = forum.upload("hook_v1.mp4")Simulate
10,000 digital twins react to your content based on Big Five personality and engagement traits. The Forum returns a virality score and per-factor suggestions.
# Pulse 10K simulated reactions verdict = await forum.simulate( draft_id=draft.id, platform="tiktok" ) # verdict.score → 0..100 # verdict.factors → hook/pacing/...
Ship the winner
A/B test up to 5 variants, see which one wins the Forum verdict, and ship only what cleared the bar.
# Compare up to 5 variants results = await forum.ab_test( variants=[v1, v2, v3, v4, v5] ) winner = results.top() # Only ship what cleared the bar
The 5-Factor Rubric
Every draft gets scored on the five things that actually drive engagement. Hook, pacing, emotion, clarity, CTA — plus a full A/B test layer on top.
Hook Score
Measure the first 3 seconds against Forum-validated patterns. Know whether your opener earns the scroll-stop before you ever publish.
Pacing Analysis
Frame-by-frame attention curve from the simulated audience. See exactly where the 10,000 twins drop off — and why.
Emotion Resonance
Measure which emotion the Forum experiences — joy, surprise, curiosity, awe — and whether it matches your creative intent.
Clarity Check
Does the Forum understand what you are saying or selling? Surface comprehension gaps before the real audience does.
CTA Strength
Measured intent-to-act from the simulated audience. Pulse every call-to-action for downstream conversion signal, not just likes.
5-Variant A/B Test
Run up to 5 hooks side-by-side. Ship only the variant that cleared the Forum bar. Shelf the rest without burning a post slot.
Three workflows I built Forum to run
Forum isn’t “AI virality scoring.” It’s a 10,000-twin simulated audience you can interrogate. These are the three jobs I built it to handle first. If yours isn’t on this list, email me at [email protected] — that’s how I figure out card four.
Cut your $4,800/mo creator agency
Drop in 247 candidate hooks for your TikTok account. Forum runs them past 10,000 simulated viewers matched to your follower demographics. The winning hook beat your last post’s engagement by 31%. Whole test took 6 minutes.
Reverse-engineer 50 LinkedIn posts
Paste your competitor’s last 50 LinkedIn posts. Forum scores each against the 2026 algorithm — carousel weight 1.9x, video reach down 200%, dwell-time-king, long-form 800-1000 word sweet spot. Surface the 3 patterns they’re winning with that you’re not.
Change the price mid-simulation
Run a launch post sim. Mid-flight, swap the price from $99 to $69 — watch the engagement curve shift live. Then change the audience from solo founders to RevOps directors. Same content, different reaction. Ask “why did Twin #4,237 share this?” and Forum exposes the decision trail.
I priced Starter at $39/mo because the engine makes zero LLM calls — heuristics + Monte Carlo, AST-test-enforced in src/methodologies/market_research/social_layer.py. The math holds at 95%+ gross margin. You don’t pay for someone else’s GPU bill.

Frequently Asked Questions
The Forum is a simulated audience of 10,000 digital twins — each one carrying a distinct Big Five personality and engagement profile. When you upload a draft, every twin reacts as an individual viewer would, giving you a distribution of responses rather than a single algorithmic guess. Think of it as a pre-flight test audience for every piece of content you ship.
Cortex Forum currently supports TikTok, Instagram Reels, and YouTube Shorts. Each platform has its own pacing and hook expectations, so the Forum calibrates its scoring accordingly. More platforms will be added based on launch demand.
Cortex Forum is a research-preview product. Accuracy is currently being calibrated against real engagement data; we do not publish a single accuracy number until that calibration completes. We would rather ship honest framing than a fabricated benchmark.
API access is available on Forum Pro. SDKs for Python and Node.js are coming soon. If you have a specific integration need for launch, let us know on the waitlist form and we will prioritize accordingly.
Most virality tools score content against past viral patterns — effectively predicting yesterday. Cortex Forum simulates a future audience: 10,000 digital twins with distinct personalities react to your content before you publish, so you see a distribution of reactions instead of a lookback score.
