Chrome extension · ChatGPT

ChatGPT gives you conversations.
Lattice gives you continuity.

Lattice turns linear chats into a structured prompt tree. Track edits, drop checkpoints, and resume work without scrolling back to find the thread.

The problem

Linear chat is fine until your thinking branches.

Decisions get buried. Working drafts disappear. Three good ideas ago is now scroll-only. You re-derive context you already earned — every single session.

  • 01Lost where you were.
  • 02Lost which version worked.
  • 03Lost which branch mattered.
  • 04Lost the shape of the thinking process.

What Lattice does

Three primitives. One continuity layer.

Each does one thing well. Together they turn a chat tab into a command surface for thinking.

01 · atlas

Atlas

The full prompt and edit map of any conversation.

↳See the structure of your thinking, not just the transcript.
parentv3 ✓
02 · family

Family View

Focus a single prompt and every revision that came from it.

↳Compare versions side-by-side without losing the parent.
checkpoint↳ resume
03 · resume

Resume

Drop a checkpoint. Pick up exactly where you left off.

↳Working state survives between sessions and devices.
Interactive · Atlas

Click a node. Watch the tree think.

A working preview of the structure layer. Selection re-routes the active path. Edits and branches are first-class.

Use cases

For anyone who works through iterative thinking.

The interface follows your work, not the other way around.

01
Students
Revision and concept branches
Hold every angle of an essay or proof. Compare drafts. Resume the one that worked.
02
Researchers
Hypothesis exploration with traceability
Branch hypotheses. Keep the chain of reasoning visible. Cite the path that led to a finding.
03
Founders
Decisions, validation, strategy paths
Pricing, positioning, GTM — explored as parallel branches with checkpoints, not buried in chat.
04
Builders
Project continuity and branch recovery
Spec, debug, refactor on different branches. Pick up where you left off without re-priming.
Why it is different

Lattice is not a chat wrapper·a note app·a transcript dump·a generic memory clone·just summaries.

It is structure·continuity·checkpoints·branch intelligence·working-state recovery.

ChatGPT is the language model. Lattice is the layer that remembers what you decided, why you decided it, and what is still unresolved — so the conversation behaves like a project, not a thread.

Trust · privacy

Your thinking stays yours.

Lattice is built deterministic and inspectable. Every artefact is traceable to its source. Storage is local-first. Trust is a feature, not a footnote.

~/lattice/atlases · stored locally·verified
Local-first
Atlases live in your browser by default. Nothing leaves your machine unless you explicitly export.
User-controlled
You decide what is captured per conversation. Pause, redact, delete — at any time.
No telemetry
Zero analytics on prompt content. Aggregate health metrics only, opt-in.
Inspectable
Every node links back to its source turn. Open it, audit it, remove it.
