Investigation software · link analysis

Built for cases that need a clear network view

LinkChart is a browser-based platform for relationship mapping and network analysis — typed entity cards, labelled links, collaboration and print-ready exports. No install: sign in at linkchart.art and open your first map in minutes.

Visual link charts

People, vehicles, addresses, phones, companies and events on one infinite canvas — the same layout your team sees in briefings and handovers.

Structured case data

Each card has fields, notes and images. Relationship lines carry meaning — not anonymous arrows lost in a slide deck.

Live collaboration

Invite editors or viewers per map. Realtime sync keeps distributed analysts aligned on what is confirmed and what still needs checking.

What the map looks like

Same cards, toolbar, and connection labels as on the canvas — drag to pan, scroll to zoom, and hover to highlight links.

Search, discover, then map the network

Most investigations start with a single clue — an email, a handle or a phone number. LinkChart connects OSINT-style lookups with visual link analysis so results do not die in browser tabs.

  1. Run a lookup

    Use free tools for email, username or phone — structured results you can review and verify.

  2. Discover connections

    Open profile links, compare overlaps and note what is confirmed vs. still a lead.

  3. Build the link chart

    Add entities to an investigation board, draw labelled relationships and document sources.

  4. Collaborate & report

    Share the map with your team, print for briefings, and revisit as the case develops.

Open linkchart

Intelligence mapping software for link charts and network analysis

linkchart helps investigation teams turn scattered facts into a clear, defensible link chart — a digital network map where every person, vehicle, address, phone number, company, event and communication profile is a structured card, and every connection is a labelled line with meaning. The product runs in your browser at linkchart.art; no installation required.

What is a link chart?

A link chart (association diagram or entity-relationship map) shows how people and objects in a case are connected. Instead of redrawing PowerPoint slides after each development, investigators maintain one living canvas that grows with the inquiry — from the first witness to charging decisions and court briefings.

Who uses linkchart?

Law enforcement and detectives map suspects, victims, associates, safe houses and vehicles. Crime analysts merge registry data, open sources and operational reporting. Fraud and insurance investigators trace companies and intermediaries. OSINT researchers document usernames, platforms and shared infrastructure.

How does it work?

Sign in, create a map, and add cards from the toolbar. Draw lines between entities and label them — owns, seen at, uses, employed by or your unit’s own taxonomy. Click a card to open the side panel for fields, notes and images. Zoom across large networks, group related cards, and print when you need a physical briefing pack.

Entity types built for investigations

Investigation quality improves when each fact sits on the right card type. linkchart provides colour-coded entities so a room full of analysts reads the map at a glance: person cards for subjects and witnesses, vehicle cards with plate and colour fields, address cards for locations, phone cards with number and carrier, event cards for incidents in time, company cards for corporate structures, and dedicated types for social and messaging profiles where digital identity matters. Note cards capture hypotheses, intelligence gaps or supervisor tasking without forcing them into a person node.

Relationship lines are not anonymous arrows. Each link carries a label that explains the claimed connection — essential when a prosecutor, partner agency or shift handover must understand the chart without a long verbal briefing. Hover a card and its network highlights, the same behaviour you can try in the homepage demo.

Network analysis workflow on one canvas

A typical inquiry starts with a seed entity — a victim, primary suspect or company — and expands as material arrives. Early charts are messy; that is expected. The value is that every new fact has a proposed place in the network, and contradictions become visible. Teams use linkchart in briefings on a large screen, then one analyst cleans layout, merges duplicates and adds fields required for the next operational step. Maps save to your account with auto-save, so long-running cases survive between shifts and weeks apart.

Collaboration and access control

Investigations are rarely solo. linkchart lets you invite collaborators to a specific map with editor or viewer roles. Editors add cards and lines; viewers see the network without changing it — useful for supervisors and partner agencies under need-to-know rules. Sharing happens through accounts on linkchart.art rather than emailing unsecured diagram files that quickly go out of date.

Security and responsible use

Maps often contain personal data and sensitive operational detail. linkchart uses HTTPS (TLS) for encrypted transport and session-based authentication after sign-in. Access is controlled per map; only owners and invited users see your charts. Your organisation remains responsible for lawful processing, retention and classification under GDPR and local rules — linkchart is the analytical layer; your policies govern when a map may be created and who may view it. Use strong passwords, lock workstations, and treat printouts like any other sensitive exhibit.

Compared to whiteboards and spreadsheets

Whiteboards are fast for brainstorming but do not scale across months or remote teams. Spreadsheets store facts but hide network shape. Presentation software makes pretty pictures but lacks a data model behind each shape. linkchart is purpose-built for criminal intelligence link analysis: typed entities, labelled links, printing, collaboration and a low barrier to entry with free registration in the browser.

Common questions about linkchart

Is linkchart the same as case management software?

No. linkchart focuses on the visual network view. It complements formal case systems, evidence stores and disclosure workflows — it does not replace them.

Can I use linkchart on mobile?

Yes. The canvas adapts to phones and tablets for review and light edits; complex layout work is easiest on desktop.
