Most people know about Wikipedia, the free online encyclopaedia that anyone can edit.
Two social entrepreneurs, Stephen Danelutti and Harry Timons, have taken Wikipedia as their model to start a site on corporate social responsibility.
Like Wikipedia, charityWiki will be open to all comers - companies, employees, social activists and governments - to post information and comment on the role firms play in charitable and socially responsible activities.
The whole enterprise has been completely financed by the two founders and they have no plans to sell advertising or sell space on the site because they want it to remain independent and neutral.
"CharityWiki will empower social activists, allow people a platform where they can have a voice and contribute their thoughts," said Mr Danelutti, who formerly worked on music downloads for Sony. "But we also want companies and governments to get involved as well."
Mr Danelutti believes that charityWiki has the potential to be more useful than social audits, commissioned by hundreds of companies annually to assess conditions in the workplace.
A report from the Clean Clothes Campaign, a collection of NGOs, earlier this month criticised many social audits for their superficiality and their failure to miss violations of workers' rights.
CharityWiki, Mr Danelutti says, would give employees who might be "discouraged" from bosses to air their grievances a forum where they can still get their views across. Workers who do not have computers can use their mobile phones to send messages or even pictures to the site.
As with Wikipedia, CharityWiki will rely heavily on self-policing and people's good intentions.
"CharityWiki will have the same philosophy of openness," said Mr Danelutti. "If people do do something wrong, then there will be the opportunity for others to correct them."
