How it works

Three steps.
That's the whole product.

01

🔍

Enter your vessel

Type an MMSI number or vessel name. AISsift will search only for that vessel as it reads the file — nothing else is ever loaded into memory.

02

📂

Drop in your AIS file

Drag and drop any AIS CSV — from NOAA, MarineTraffic, Spire, or your own data. The file stays on your computer. Nothing is uploaded anywhere.

03

🗺️

See the track

Your vessel's full path appears on an interactive map with clickable position points. Pro users can export clean CSV or KML for Google Earth.

Built for professionals

Everything you need.
Nothing you don't.

⚡

Filtered parsing

AISsift reads only your vessel from the file. A 500MB NOAA file with millions of records loads in seconds — because 99% of it is skipped immediately.

🔒

Completely private

All processing happens on your machine. Your files are never uploaded, stored, or transmitted. This matters for legal and insurance work.

📍

Interactive map

Full vessel track with start and end markers. Click any point for timestamp, speed, and heading. Zoom, pan, and explore the route in detail.

📁

Any AIS source

Works with NOAA, MarineTraffic, Spire, AISHub, or private receiver data. AISsift auto-detects the format — no configuration needed.

📅

Multi-day consolidation

Upload files from multiple days and AISsift stitches them into one unified track. Filter by date and time range to focus on what matters. Pro

💾

Clean exports
