For donors
Values Compass
Answer thirteen quick questions about what you care about and see which causes fit you, why they fit, and what the moral lenses you use least would show you.
Portfolio Builder
Split a giving budget across causes when you aren’t sure which moral framework is right, compare two ways of doing it, and see how much they agree.
Charity Lookup
Search the Charitology Charity Index by name, see where on the chain from symptom to source a charity’s work is thought to act, and open the public registries in one click.
Browser Extension
Puts the Giver’s Checklist on donation pages and one click away everywhere else, with a lookup in the open charity registries. Collects nothing.
Impact Calculator
See what a gift could achieve, as a range, for interventions with a published cost per outcome, and see which interventions have no reliable per-dollar estimate at all.
Compare Tool
Put two or three interventions side by side on depth, evidence, durability, feedback, who steers and cost, and see exactly where they differ. There is no overall score, because the trade-offs are yours to weigh.
Giving Dashboard
Keep a private log of your gifts and see where your giving goes, by cause and by depth, from relief for today to work on sources.
Charitology Wrapped
Turn a year of logged gifts into a card you can share, showing where your giving acted and the kind of giver it makes you, with or without the dollar amounts.
One-Click Split
Split one giving decision across several charities, with whole-dollar amounts that add up exactly and a step-by-step list of where to give.
Legacy Planner
A private worksheet for leaving gifts to charity in your will, with a printable summary and sample wording to take to your estate attorney.
Disaster Response Guide
What responders and researchers advise about giving after a disaster, a planner that splits one gift across relief, recovery and preparedness, and a calendar reminder to give again when the news has moved on.
Gift Giving
Make a card for a donation given in someone’s name, with what the gift does, a personal message and the reasons you chose it. No amount required.
For nonprofits and funders
