Evaluate, improve, and steer your multimodal agent.
SailFar builds a realistic simulator and a bespoke evaluator sharpened by your feedback, fixes failures through your coding agents, and steers your agent in production.

Foundation models struggle to grade the way you need.
Homegrown evaluators drift and need constant realignment.
Human testing and labeling doesn't scale with your product.
Quality issues surface in production, found by your users.
The feedback loop you've always wanted.
Simulate
Realistic simulation covers the full behavior space, from common paths to adversarial cases, coverage you'd never script.
Evaluate
A self-evolving evaluator grades voice, video, and image natively, learning from minimal feedback to stay aligned with your quality bar.
Improve
SailFar integrates into your coding agents via skills to analyze the failure, fix it, and re-run to verify.

Steer
A lightweight evaluator runs inline in production, remedying failures in real time at scale.
FAQ
How can I trust the simulation is comprehensive and realistic?+
Grounded, seeded, and guided. SailFar first explores your agent's environment, so every scenario reflects the tools, data, and constraints it actually operates under. Coverage then scales far beyond what you'd script by hand, and an optional seed of production traffic, even a handful of samples, makes it sharper still. And your team's domain expertise guides the whole set toward the cases that matter most in your world.
How much work does SailFar take from my team?+
Minimal feedback, by design. You correct the evaluator when it misses and guide the simulator toward the cases you care about, a few examples at a time. Every input becomes a rubric or a scenario the system keeps, and SailFar evolves both alongside your product, with no eval suites to write and no relabeling campaigns to run.
Is my data used to train models?+
No. Your calls, clips, and traces stay yours and never train models, ours or anyone else's.
Does SailFar work with my stack?+
Yes. SailFar is agnostic to your model provider, SDK, framework, and API provider, and starts with no code changes.
