As well as trees and chromosome mapping, the site hosts the tools below.
You can also view a list of other third-party DNA tools for genealogy hosted elsewhere.

Early prototype table version
A tool to use the shared cM from multiple matches to test out hypotheses
Convert your AncestryDNA 'Chromosome Painter' segments into chromosome, start and stop points that you can use in your chromosome map

A tool that can help group matches into maternal and paternal (or link them to a common ancestor) by filtering a list of segments using other lists of segments or matches from known relatives
Try the bucketing tool
A collection by Cody Ely of real example matches and shared segments from a wide variety of relationships, to be used for relationship prediction and reference.

Takes your cluster file and segments files and generates a chromosome map with the segments grouped by cluster.
Copy and paste the segments that you and a close relative share with a DNA match, and this tool will output just the segments that you do not share with the match.
Paste multiple sets of segments that siblings share with a match and this tool will estimate the total amount of DNA the parent is likely to have shared with this match.
Copy and paste two or more sets of segments that multiple family members share with a single match. This tool will identify the distinct segments and return cM values for each along with the total cM.
Copy and paste in two sets of segments. The tool will return just those that are common to all sets.
Enter the chromosome, start, and end positions and this tool will calculate an estimated number of centiMorgans (cM) to one decimal place.
Paste in segments, and the tool will return the segments and total filtered cM according to the criteria you set
A simple tool to extract a CSV of clusters and matches from your Genetic Affairs or MyHeritage autocluster output.
