Personal Graph Platform

Your identity is a personal graph, not a flat profile

Sigmet builds your personal graph - a structured, evolving map of your skills, projects, evidence, relationships, and goals - split across public, private, and AI layers. The graph is the source of truth. Everything else is a projection.

Three layers of your personal graph

Sigmet does not treat you as a flat profile. It treats you as a living graph of identity, activity, context, and change over time.

Public Graph

A structured, machine-readable identity surface. Expertise, projects, evidence, and trust signals visible to other people and external AI systems.

  • Expertise discovery
  • Project history
  • Evidence of work
  • Domain authority signals

Private Graph

Your deep context layer. Goals, constraints, preferences, and plans available only to you and your personal AI for better advice and decision support.

  • Personal goals & plans
  • Working style & constraints
  • Private reflections
  • AI-powered planning

AI Layer

An interpreter and operator over your graph. AI suggests updates, detects stale data, clusters domains, and drafts summaries - but never silently rewrites your identity.

  • Graph candidate suggestions
  • Staleness detection
  • Evidence-backed summaries
  • Domain clustering

How it works

Every meaningful action updates your personal graph. Posts are evidence. Integrations enrich data. AI suggests - you decide.

01

Build Your Graph

Add skills, projects, goals, and experiences. Every profile field becomes a structured node in your personal graph.

02

Create Evidence

Write posts, connect integrations, import artifacts. Each action generates graph events and accumulates proof of your work.

03

Let AI Enrich

AI extracts entities from your content, suggests relationships, detects stale data, and proposes updates - all reviewable by you.

04

Control Visibility

Set granular permissions on every piece of data: who sees it, whether AI can use it, and how it influences your public identity.

How people use their personal graph

Every role benefits from a structured personal graph. Here is how different people build and leverage theirs.

Developer
TypeScriptReactSigmet.appOpen Source

Maps skills to shipped projects with real evidence from GitHub, commits, and deployed work.

Researcher
MLNLPPublicationsCollaborators

Connects publications, topics, and collaborators into a structured knowledge graph with evidence.

Founder
ProductFundraisingTeamGrowth

Shows trajectory from idea to shipped product - goals, milestones, and domain authority over time.

Why Sigmet is different

Sigmet is not another social feed, CV builder, or AI memory app. The difference is the personal graph model.

Graph, Not Profile

Your personal graph is a living state machine of nodes, edges, and events - not a static collection of fields. Every meaningful action updates it.

Evidence-Based Reputation

Reputation derives from graph signals: evidence volume, verification, recency, and domain concentration. Not from vanity scores or self-description alone.

Domain Relevance

A person is never "important" in the abstract. Sigmet reasons in topic layers - relevant, credible, active, and trusted in specific domains.

Visibility + Usage Permissions

Public vs private is not enough. Sigmet separates who can see your data from how it can be used - by AI, in summaries, for ranking, or for export.

Feed as Graph Events

The feed is not a generic timeline. It is a stream of graph events: evidence drops, milestones, project updates, goal shifts, and domain signals.

Integrations as Graph Enrichment

Connected sources like GitHub, X, and LinkedIn enrich your graph with imported evidence, activity signals, and confidence - not cosmetic badges.

What your personal graph unlocks

A personal graph is not just data - it changes how you are understood, discovered, and supported by AI.

AI that actually knows you

Your personal graph gives AI real structured context about your skills, goals, and work - not guesses from a flat bio.

Proof, not claims

Every skill and project in your personal graph is backed by evidence - posts, integrations, artifacts. Reputation you can verify.

Discoverable by domain

People and AI systems find you by what you have actually done and know - not by what you wrote in a headline.

Core principles

1

Your personal graph is the source of truth. The profile is a projection.

2

Posts are not only content. Posts are graph events and evidence.

3

Integrations enrich the graph. They do not blindly define truth.

4

AI can suggest, infer, and summarize. AI should not silently rewrite identity.

5

Permissions govern both visibility and usage.

6

Reputation is a derived layer, not a manually declared one.

7

A person is relevant only in context, domain, and time.

8

Every meaningful change is representable as a graph event.

How AI systems use your personal graph

External AI platforms query Sigmet's structured graph data to understand people, verify expertise, and discover relevant contributors - with your explicit permission.
