Your voice agent breaks in ways you have not imagined yet.
Ominous runs 1,000 scenarios against your agent in minutes and fixes what it finds.
Ominous discovers every weakness before your customers do. It fires hundreds of real-world scenarios at your agent, spots where it fails, and automatically patches those gaps. After every run, your Brain Health score updates to show exactly how much your agent improved.

Runs while you sleep
Schedule Ominous after every deploy. Failures surface in your dashboard before you have finished your morning coffee.
Adversarial by default
Every run includes hostile callers, prompt injection attempts, policy violations, and language edge cases. Not just happy paths.
Market-ready activation built in
Ominous 2.0 tracks Brain Health on every run and marks agents as market-ready once your target is reached. Activate to live only when you approve.

Train and audit your agent in any language
Select a training language before running Ominous and the entire scenario wave fires in that language. Run the same agent across languages to surface multilingual failure modes invisible in English-only testing.
Each language run produces an independent Brain Health score so you know exactly which locales need work.
Ominous runs, detects, fixes, and verifies — without you writing a single line.
Ominous 2.0 is fully autonomous from detection to fix. Once you start a run, it reads your agent, generates a complete adversarial scenario library, fires every scenario, and classifies every failure. When issues are found, Ominous automatically creates a targeted candidate fix — no manual triage, no scripting, no guesswork.
The fix is held as a candidate until you manually run the second verification wave. That wave proves whether your agent actually improved before anything touches your live prompt. You stay in control of the final call — Ominous handles everything else.
Zero-script scenario generation
Ominous reads your website, infers your industry, and builds a full non-repeating scenario graph automatically. No test scripts to write or maintain.
Candidate fix in seconds
After every run, Ominous clusters failures, removes duplicates, and generates a safe candidate prompt patch targeting the highest-severity issues first.
Manual activation gate
Fixes never go live automatically. You run the second verification wave yourself, review the improvement in Brain Health, then activate only when you approve.
How Ominous works
One button. Four phases. Your agent comes out tighter on the other side.
01
Analyze
Ominous scrapes your agent's website, reads the system prompt, detects business type, and builds an industry-specific scenario graph.
02
Run
1,000 non-repeating scenarios fire against your agent: happy paths, edge cases, hostile inputs, multilingual calls, latency races.
03
Detect + Fix
Every response is scored. Failures get classified, ranked by severity, and auto-patched with targeted prompt edits.
04
Verify + Score
You manually run a second verification wave against the candidate fix. Results feed directly into Brain Health so you can activate only when metrics improve.
Your agent's fitness score, live
After every Ominous run, a Brain Health percentage is calculated from pass rate, error rate, latency stability, and fix coverage. It starts wherever your agent is today and climbs as Ominous clears failures and confirms fixes held.
Most agents see Brain Health improve from the low 60s to the high 90s within 5 to 8 runs. The number never plateaus.
Token pricing
1 token = 1 scenario. 1 run = 1,000 scenarios = 1,000 tokens. Simple and linear.
Tokens never expire. 1,000 free tokens included with every VXERA account. No subscription required.
