Privacy-first memory for AI agents

Memory that knows
what to keep.

Echo Veil is a living memory layer for AI systems—designed to keep active context sharp, let stale knowledge rest, preserve contradictions, and make uncertainty impossible to hide.

01 / THE SYSTEM

A memory garden,
not a memory dump.

Most agent memory gets bigger forever. Echo Veil uses current intent to decide what stays active, what rests, and what moves into durable retrieval—without erasing the history of how knowledge changed.

LEVEL 1Active WorkspaceFast · Focused · RAM

Memory Vines orbit current intent. Low-proximity context moves into Twilight instead of cluttering every turn.

LEVEL 2Metadata IndexSearchable · Sparse · Durable

Compact vector metadata and lifecycle clues make cold memories findable without loading the whole archive.

LEVEL 3Latent ArchiveCold · Historical · Recoverable

Evicted context becomes recoverable history. Fossilized Echoes preserve contradiction instead of rewriting the past.

02 / USE CASES

Built for agents
with a long story.

If your AI needs continuity across days, projects, customers, or investigations—but cannot afford infinite context—Echo Veil gives it a disciplined way to remember.

01

Customer & field copilots

Keep estimates, decisions, and customer context close without dragging every old conversation into every prompt.

02

Long-running research

Preserve competing hypotheses, surface contradictions, and let useful context rest until the inquiry returns.

03

Regulated workflows

Add explicit confidence gates, encrypted vector paths, and a fail-closed production boundary around sensitive retrieval.

04

Personal knowledge agents

Build continuity that follows current intent instead of turning a lifetime of notes into permanent prompt baggage.

05

Multi-agent operations

Give specialist agents a shared memory policy while the host application keeps authorization and payload ownership.

06

Case & project memory

Carry forward the decisions that matter, checkpoint active work, and archive context with its lifecycle metadata intact.

03 / WHY ECHO VEIL

Smaller context.
Stronger continuity.

Add Echo Veil when a vector database alone is not enough. It adds policy, metabolism, confidence, and privacy around retrieval—while leaving your models and payload store in your control.

L1active focus

Less context drag

Intent proximity and decay keep the active workspace focused, reducing the temptation to send an ever-growing transcript to the model.

3memory tiers

Better memory hygiene

Twilight, reinforcement, locks, and resurrection give memory an understandable lifecycle instead of a binary keep-or-delete switch.

5confidence bands

Honest uncertainty

Confidence bands make weak reconstruction visible. Inferential answers require consent; data obscurity stops generation.

4security modes

A real privacy boundary

Use plaintext locally, AES-GCM in staging, local CKKS, or an attested enclave path—with capabilities reported instead of implied.

04 / WHERE IT FITS

The policy layer between
your agent and its memory.

Echo Veil does not replace your model, embedding provider, or authorized content store. It coordinates what memory is active, what is retrievable, and when confidence is too low to generate.

Production requires the configured attested enclave shield.

05 / PRIVACY BY MODE

Start simple.
Harden without pretending.

Every environment says exactly what it can protect. Echo Veil refuses production startup when CKKS, verified hardware isolation, fresh attestation, or the proof gate is missing.
