Persalto

Paid Self-hosted

What Persalto is

Persalto is a self-hosted search system for video, audio, images, and documents held on infrastructure a customer controls. It searches mixed archives with natural-language queries and returns synthesized answers with citations that point to source video frames or document paragraphs. For video, it creates scene breakdowns, keyframes, summaries for each scene, detected entities, and transcripts that identify speakers and timestamp each word. Users can search transcript text and visual detections together, with matching moments returned as timestamps they can seek to.

The library reads files in place from SMB, NFS, S3, and Isilon. Watched folders can automatically ingest new media, and content hashes are used to deduplicate assets. An activity console tracks ingest, transcription, scene detection, vision, and document parsing, including engine status, retries, and dead-letter queue support. It also provides structured JSON logs, Prometheus metrics, and correlation IDs.

Persalto uses containerized, declarative deployment on customer- or partner-owned NVIDIA GPU servers at a chosen facility or data center. Air-gapped operation is available for teams such as government, defense, and critical infrastructure. Licenses are sold in two-GPU increments; assets, queries, and reprocessing are not metered. Annual renewal includes the platform, model and app updates, and support.

Who it suits

Persalto suits broadcast and post-production, sports and live entertainment, legal and compliance, and government, defense, or critical infrastructure teams with media and document archives. It is designed for organizations that want search deployed on infrastructure they control, including air-gapped environments.

Verdict

Choose Persalto if your team needs cross-format archive search on infrastructure it controls, especially when air-gapped operation matters. Its two-GPU license increments and on-request pricing may be a poor fit for teams that cannot use that deployment model or need a listed price before engaging.
