Your personal research desk. Staffed by agents.

Give Cerno one mission. It researches text and video, applies your quality bar, and returns one finite briefing where every claim is inspectable.

THE PROBLEM

The internet does not have an information shortage.
It has a judgment problem.

01

Feeds

Optimize engagement—not the work in front of you.

02

Read-later

Collect more material—and leave the reading to you.

03

Summaries

Make everything shorter—without deciding if it matters.

THE MISSING FUNCTION Decide what deserves attention now—for this person.

THE PRODUCT

One mission in.
One finite briefing out.

A Focus Thread gives Cerno temporary mission context. It stays separate from durable taste, so today's project never silently rewrites who you are.

  1. 01
    Declare the mission

    Current work, desired decision, boundaries, and freshness.

  2. 02
    Research selectively

    Fetch promising text and resolve one video into timestamped moments.

  3. 03
    Judge personally

    Compare evidence with the Focus Thread, TasteDoc, and personal index.

  4. 04
    Publish finitely

    One bounded run can produce one canonical briefing. Never a feed.

AI AS AGENCY

A research desk,
staffed by agents.

The completed unit of work is not a chat response. It is a trustworthy, cited briefing that replaces the personal research-and-briefing function end to end.

THE EVIDENCE SPINE

Every decision
shows its work.

A search snippet can create a candidate. It can never become evidence. Every published claim points to a fetched passage or timestamped transcript moment, locator, and content hash.

  1. 01
    Claim

    Atomic, decision-relevant finding

  2. 02
    Exact source passage

    Contiguous primary-source substring

  3. 03
    Provenance

    Source locator + SHA-256 content hash

  4. 04
    Personal judgment

    Novelty against the index + TasteDoc rules used

  5. 05
    Reviewed correction

    Readable profile diff—never silent retraining

EXACT SOURCE PASSAGEEXACT MATCH

“The result is four recurring failure modes: unregulated growth, missing semantic revision, capacity-driven forgetting, and read-only retrieval.”

VERIFIED PRODUCTION RUNS · 12 JUL 2026

Two missions.
Every claim inspectable.

Verified in an authenticated production workspace using live LinkUp retrieval, timestamp-bounded VideoDB streams, and the bearer-protected Hermes runtime on Azure. Search-result snippets were never used as evidence.
