The BigSpy alternative that decodes why it wins — and makes the next one.
An ad library shows you what competitors are running. ViralMojo is an agent that goes and finds what's winning in your niche — organic and paid — decodes why it works, reads the audience, and turns it into your next video. The same spying. A completely different output.

In their own words.
Why an agent, not an ad library
“If you're spending hours scrolling the Ad Library by hand, exporting CSVs from Ads Manager every Monday, staring at a blank doc trying to write ad variation #14…”
Why signal beats guessing
“posting without knowing what's working in your niche is just noise. the agent gives you signal.”
Why live, not a static database
“i genuinely think organic content is becoming one of the biggest moats in business — especially for apps + ecommerce brands.”
Why your exact niche
“You don't guess what to post. You check what's working in your niche right now, then make content that matches.”
Why decode, then adapt
“your competitors have already spent millions testing. you don't have to start from scratch — study what's working in your niche and adapt it.”
Why start from organic
“Start with $0 organic content on TikTok / IG. Post daily and find your natural winners.”
Questions about switching.
Yes. If you use BigSpy to find what competitors are running and source creative inspiration, ViralMojo does that job and keeps going: it finds your niche's winners (organic + paid), decodes why each one works down to the audience's own words, and turns the insight into a finished video. If you mainly want a giant cross-platform ad database to browse and spy on, BigSpy is purpose-built for that — many teams run both.
BigSpy stops at showing you the ad and its metadata. ViralMojo decodes the creative (hook, hook type, CTA, story, structure, voice), reads the audience (comment sentiment, top questions, buying signals, best-fit ICP), runs three-layer research (product + customer + competitor) from just your URL, and renders the next video in six post-ready formats. Spying is one input; ViralMojo owns the loop from discovery to finished ad.
Both. BigSpy is paid-only across its 10 ad platforms. ViralMojo searches live organic (TikTok + IG Reels) and paid (Meta Ads) winners in your niche, so you start from what's actually breaking out, not only what someone is paying to run.
ViralMojo is $79/mo (Starter), $199/mo (Creator), and $399/mo (Pro). All three tiers have the same features — higher tiers only add monthly credits — and there's no free plan. BigSpy is cheaper to start: a functional free tier (5 daily queries, Facebook only) and Pro at $149/mo. You're paying ViralMojo for what it makes (decoded research + finished videos), not just for what it shows you.
On demand, plus automatic. You can ask the agent to search your niche any time in plain language, and ViralMojo also auto-refreshes your competitors' winners every week — so the workspace keeps surfacing new signal, not a static snapshot.
Yes. Give ViralMojo your product URL — no ad account, spend history, or saved-creative export needed — and the agent finds, decodes, and starts briefing from your niche's winners. Many teams keep BigSpy for broad cross-platform spying and add ViralMojo to turn what they find into finished ads.
