Update: This no longer works because of the removal of Heroku free tier and changes to the Twitter API
Created for the EUvsVirus hackathon.
Tweet @checkiftrue with the text "claim: <claim>" where <claim> is the claim you'd like checked. @checkiftrue should reply within a few minutes with information pulled from the Google Fact Check Tools API about whether the claim is likely to be true or false.
See the bot's replies for examples.
