ES Archive for macOS

ES Archive

Your AI now keeps an archive.

Every session builds on the last: decisions, insights, and context, stored privately on your Mac and recalled when they matter.

Two sides of continuity

One archive.
Two perspectives.

The experience is almost invisible to you. For your AI, it changes the nature of every new session.

Continuity, finally

An assistant that doesn't meet you for the first time every day.

AI assistants are capable, but every new conversation begins without your projects, decisions, or ongoing work. You explain yourself again. The assistant catches up again.

ES Archive changes the premise. It gives your assistant a curated, searchable body of knowledge that grows across sessions—not a chat history, but context with provenance, structure, and a reason to remain.

Inside the archive

Disciplined continuity.

Your assistant does the filing, linking, and retrieval. You simply continue the conversation.

01

Your AI remembers selectively

Decisions and durable insights survive. Conversational debris does not. You never manage the archive by hand.

02

Memories can evolve

New evidence can revise an earlier memory without erasing its history—or why a different conclusion once made sense.

03

On-device intelligence

Multilingual EmbeddingGemma vectors are computed locally with Core ML. Your AI can retrieve across more than 100 languages.

04

Many voices, not one profile

Different AI personas can develop distinct, attributable perspectives on you without flattening them into a single canonical view.

Archive Scope

See ideas become a body of knowledge.

Archive Scope reveals the themes, hubs, and unexpected connections in your work. Its tag cloud turns a growing archive into a legible, evolving vocabulary.

Tags are intentional—not a spray of automatic keywords. You and your assistant build a useful vocabulary together.

One engine, two connections

Choose the doorway your assistant speaks.

Built native, on purpose

Objective-C in 2026?

Absolutely. ES Archive is written throughout in Objective-C—not from inertia, but because dynamic dispatch, Core Data, CloudKit, and a heterogeneous MCP tool surface fit together beautifully here.

Competence before compliance.
