How it works
01
Know your vessel? Enter an MMSI or name first — safe for any file size. Just have a file? Drop it in and explore all vessels. Pro users can consolidate multiple days into one unified track.
02
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
The vessel's full path appears on an interactive map. Click any point for timestamp, speed, and heading — or use the timeline scrubber to move through the track position by position.
Built for professionals
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.
All processing happens on your machine. Your files are never uploaded, stored, or transmitted. This matters for legal and insurance work.
Full vessel track with start and end markers, color-coded per vessel, with visibility toggles. Click any point for timestamp, speed, and heading.
Click any vessel in the legend to activate a timeline. Drag the scrubber to move a position marker along the track — see exactly where the vessel was at any moment.
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
