Your archive should remember why things matter.
CHRON.OS is a local-first archival intelligence system for preserving documents, media, provenance, temporal context, and user-weighted meaning — without making the cloud the source of truth.
Most folders become digital junk drawers over time. CHRON.OS helps turn that around.
Most folders become unnavigable over time — files pile up, context disappears, and finding something from three years ago means hoping you remember what you named it. CHRON.OS turns scattered files into a searchable, connected archive. It keeps track of documents, media, timelines, duplicates, relationships, and project history so important things don't disappear into chaos.
Archive
Preserve files, metadata, source paths, hashes, and provenance. Originals are never mutated.
Understand
Classify by domain, form, entities, emotional salience, and user-adjusted meaning weights.
Navigate
Move through files by chronology, ontology, relationships, duplicates, and trace paths.
Remember
Build continuity across projects, cases, research, creative worlds, and operational records.
Source → hash → metadata → meaning → trace.
CHRON.OS keeps more than the file itself. It preserves the trail around it — where it came from, when it changed, and how it connects to the rest of your archive.
Not every file matters equally. Archivist helps surface the ones that do.
Archivist helps surface the files that actually matter.
Some files are just files. Others are the ones tied to a decision, a breakthrough, a revision, an investigation, or a turning point in a project. Archivist helps CHRON.OS identify which is which — and lets you adjust that weighting as your understanding evolves.
See how the archive works in practice.
These are real screens from the live beta. Browse relationships between files, trace project history, inspect artifacts, and explore how CHRON.OS organizes information over time.
Clusters show where artifacts collide. Strings show inheritance, recurrence, semantic echo.
Field · Domain · Artifact · Lineage · Echo · Meaning. Each lens reframes the same field.
application/pdf · image/png · image/jpeg · text/plain · visual media · civil litigation · housing law.
Domains set orbital lanes. Meaning weight pulls important artifacts toward the User Knowledge Well.
205 domains across the live archive. Drag to pan, click a domain to isolate.
The gravitational center. Significance accumulates here over time.
Significance, score, role, horizon, emotional valence — all attached to the artifact.
Local user-weighted context wins over inferred meaning.
document · applied · legal-documents · research-paper. Editable, traceable.
Every related artifact, every shared domain, every chain of inheritance — kept and walkable.
Whitepapers, analyses, constitutions, landing pages — all on the same field.
If it entered the archive, the path back is preserved.
Ask Archivist to find files, explain structure, create folders, or review the ontology.
Pane and bubble share the same local history. Stays on this device unless context is required.

What just landed and what carries weight, surfaced together.
Inspect file weight; copy selected sources into CHRON.OS without changing the original.

Your files stay under your control — by default, not by request.
Encryption is your call
Passphrase encrypts settings, sidecars, uploads, and the local search index. Local presence factors register here.
Cloud, local, or entirely on-device

Your original files are never touched
Browse, preview, and bring files into CHRON.OS without moving or modifying the originals.
Your computer stays in control. Not a cloud account.
CHRON.OS is designed so your archive starts with you — not a cloud account. Your original files stay untouched on your machine unless you choose otherwise. Cloud tools and external services are optional add-ons, not requirements.
Everything starts on your device. No sign-up, no cloud account required to get started.
CHRON.OS works with copies. It never renames, moves, or modifies your original files.
Where a file came from, when it changed, and how it got there — all kept with the file.
The full experience works without an internet connection. Cloud tools are optional and always opt-in.
Cloud sync, OAuth, and third-party integrations are off by default. You enable them only if and when you need them.
Trust topology
Core features are live and improving quickly.
The core archive, file preview, duplicate detection, timeline navigation, dashboard, and relationship views are all working. The instrument works. The archive grows. Advanced media understanding, external cloud tools, and deeper Atlas performance are under active development.
Start building an archive you can actually navigate.
Point CHRON.OS at a folder and let it begin organizing your documents, media, research, and projects into a connected archive you can explore and search over time.
Recommended for most Windows users: one-click installer. Portable ZIP is for no-install testing or users who already have the required runtime pieces.
