The shift
AI assistants are replacing search.
Most brands have no idea how they look in them.
Your customers stopped Googling and started asking. They ask ChatGPT for the best CRM. They ask Perplexity for the best running shoes. The answer they get is the answer they trust, and you don’t know if your brand is in it.
Weekly active users on ChatGPT alone, many making purchase decisions before they ever search Google.
Domain overlap between ChatGPT and Perplexity citations. Tracking only one platform misses 89% of the picture.

Of LLM responses don’t fully support the sources they cite. Position and source matter enormously.

Everything you need
Full AI visibility stack, in one product
Twelve focused capabilities, no fluff and no dashboard graveyard. Each one feeds the others so you spend less time interpreting and more time acting.
Five-Engine Coverage
ChatGPT, Gemini, Perplexity, Claude and DeepSeek, tracked together so you see the full AI search picture, not one platform’s slice.
- All 5 major AI engines
- Mention rate & position
- Competitor share-of-voice
- 30-day trend lines
Daily Automated Runs
Your prompts run every single day across every platform. Drift is caught the next morning, not the next quarter.
- Automatic 02:00 UTC daily run
- Manual “run now” on demand
- Audit trail per run
- No CSV uploads, ever
Composite GEO Score
A single 0–100 number that combines mention rate, position, sentiment and citations. Watch one number, understand everything.
- Score 0–100 per brand
- Per-platform breakdown
- Per-prompt drill-down
- Sentiment-weighted
Confidence Intervals on Every Metric
Wilson 95% CIs on visibility, mention rate and position. We tell you when a number is reliable, and when it isn’t.
- Wilson 95% intervals
- High / medium / low confidence tiers
- No vanity point estimates
- Statistically defensible
Statistical Sample Bootstrap
Every prompt runs 5 samples a day until it hits 70 observations (the threshold for real statistical validity), then maintains.
- Bootstrap-then-maintain
- 70 samples per (prompt, model)
- Auto throttle when stable
- Re-bootstrap on drift
Verified Improvements Only
When you ship content, we don’t claim it worked unless a two-proportion Z-test says the lift is real. No vanity wins.
- Two-proportion Z-test
- Per-prompt noise floor
- Before/after lift in pp
- No false-positive victories
Weekly Gap Reports
Every week, a Claude-generated report on which prompts you’re losing, which competitors win them, and what content closes the gap.
- Per-prompt content briefs
- Competitor URL analysis
- Content calendar suggestions
- Email + dashboard delivery
Prioritised Improvement Plans
Specific actions, ranked by impact and effort. Not “improve your content”. Actual pages, topics and structural fixes.
- Impact × effort scoring
- Page-level recommendations
- Status tracking per action
- Progress vs. last week
Citation Intelligence
See which sources AI engines actually cite for your queries, and why those sources won. Use it to decide where to publish next.
- Source URL extraction
- Citation context summaries
- Domain win-rate analysis
- PR target identification
Auto-Discovered Competitors
We find your real AI-search competitors by scanning who shows up alongside you in actual responses, not who you think they are.
- 3–10 competitors per brand
- Detected from live AI responses
- Updated daily
- Manual override supported
Deep Compare
Head-to-head GEO comparison vs. any competitor, broken down by platform. Know exactly where you win and where you lose.
- Head-to-head GEO scores
- Per-platform breakdown
- Win / lose indicators
- 30-day rolling window
AI Readiness Score
An audit of how AI-friendly your site itself is: structured data, content depth, citability. Fix the foundations, not just the symptoms.
- Site-level structural audit
- Content depth scoring
- Schema & metadata checks
- Re-scored automatically
Why it’s different
Most AI tracking tools show you a number.
We show you whether to trust it.
The category is full of tools that run a prompt once a week and call the result your “AI visibility.” That’s a coin flip dressed up as analytics. ViziBull treats AI visibility as a real measurement problem.
- Real sample sizes. Bootstrap-then-maintain sampling hits 60–100 observations per (prompt, model) within two weeks. That’s the threshold the academic literature actually requires.
- Wilson 95% confidence intervals on every proportion metric. You see the range your visibility could actually be in, not just a point estimate that lies to you.
- Verified improvements. Two-proportion Z-test gates every “your action worked” claim against a real noise floor. No false victories.
- Separated metrics. Visibility, mention rate and citation rate are different things. We don’t squash them into one fake composite that hides the truth.
Sample dashboard view
The honest comparison
Most AI trackers show you noise. ViziBull shows you signal.
AI engines are non-deterministic. Ask ChatGPT the same question twice and you’ll get different answers, different brands, different rankings. A tracking tool that runs one weekly query is showing you a coin flip dressed up as a dashboard. The number on screen is real. What it means is unknowable.
The same prompt. Five runs. Five different snapshots of you.
Real example pattern: a single ChatGPT query, asked five times in one hour. Your brand’s position swings every run.
What a single-sample tool tells you
Whichever one of those five rows it happened to catch. Your “visibility = 0%” or “visibility = 100%”, both equally likely, both equally meaningless.
What ViziBull tells you
Across enough runs to know: visibility 60% (95% CI 52–68%). The dashboard reports the actual rate plus the range it could really be in. You act on signal, not vibes.
Samples per metric, in your first 14 days
Higher is more reliable. 60+ = statistical validity.
Typical AI trackers
one weekly run
ViziBull
5 samples × 14 days
ViziBull crosses the validity threshold inside the free trial. Typical trackers don’t cross it for months, if ever.
Why this is the right way to do it
AI search is non-deterministic. The only honest way to track it is: enough samples to drown out the variance, confidence intervals on every number, and a statistical test before claiming a “win.” That is exactly what ViziBull does on every plan, starting at $69/month.

FAQ
Common questions
How is this different from a regular SEO tool?
Traditional SEO tools track Google rankings. ViziBull tracks how AI assistants (ChatGPT, Gemini, Perplexity, Claude, DeepSeek) talk about your brand. A different question with a different answer. The two are complementary; you’ll want both.
Why do I need confidence intervals if I just want a number?
Because the number alone is meaningless. If we tell you “your visibility is 40%” with no context, that could mean 38–42% (reliable) or 5–75% (basically a guess). You’d act on those very differently. We make the difference visible so you don’t ship content based on noise.
Do I need a credit card to start the trial?
No. Sign up with email, run a 14-day trial at Starter limits, and only enter payment details when you’re ready to convert.
Can I trial Pro or Agency for free?
All trials run at Starter limits, which is what lets us offer the trial without a credit card. When you convert, pick any plan. The full feature set on the higher tiers (more brands, more prompts, more competitors in Deep Compare) unlocks the moment you subscribe.
What happens to my data if my trial expires?
Your dashboard becomes read-only. Your data is preserved for 30 more days so you can convert at any time without losing anything. After that, it’s permanently deleted.
Which AI engines do you track?
All five major ones: OpenAI ChatGPT (GPT-4o), Google Gemini, Anthropic Claude (Sonnet 4.5), Perplexity (sonar-pro), and DeepSeek. Every prompt runs against every engine, every day.
Can I cancel anytime?
Yes. Cancel from the account settings, no questions asked. You’re billed monthly, so cancelling stops the next charge.
Is there an API?
An API is on the roadmap for Agency and Enterprise plans. Contact us if you have a specific integration in mind. We’ll move it up the queue if there’s demand.
