# Synapse draws lines between After Effects layers that stay attached

Davey released [Synapse](<https://motionfun.net/tools/synapse>), a free After Effects tool that draws lines between your layers and keeps them attached while the layers move. Select some layers, click one tile, and the lines follow every move, parent and camera.

There are [three ways to link](<https://motionfun.net/docs/synapse/introduction>). Chain connects the layers one after another in the order you selected them. Hub connects the first layer you picked to every other one. Web links every pair of layers closer than a distance you set and fades each line as the pair drifts apart, which gives you a plexus look for up to 40 layers.

Each click makes one shape layer that holds the lines, with an effect for width, color, sag and how much of each line is drawn. You can keyframe that effect to draw the lines in.

Synapse isn't a separate download. It lives inside [Motion Dock](<https://motionfun.net/motion-dock/start>), Motion Fun's free panel, which installs as a ZXP extension and needs After Effects 2022 or newer. Motion Fun says Synapse is free forever, with no trial, no watermark and no locked features. It's the third free tool in Davey's run of one a day, after Curvy.
