Forensic Architecture believe many of the witnesses of the fire hold recordings on their smartphones or cameras that could help piece together how the blaze that killed 71 people began and spread.
The group of architects, scientists and researchers based at Goldsmiths, University of London, is asking for submissions of footage via its Grenfell Media Archive.
The organisation plans to use the footage to build a free public resource, synchronising the videos and placing them within a 3D model of the tower in west London.
"Each of these recordings might have captured only a small part of the event, but together they add up to an extensive and powerful picture of what happened that night," said a statement from the group.
"We routinely work in areas of conflict or violence around the world, but the Grenfell Tower fire has brought our focus back to the city in which we live and work," it continued.
"We want to combine the techniques we have developed with the thousands of pieces of evidence captured by cameras across London, to create a powerful way for members of the public to better understand how this unprecedented tragedy occurred."
The fire that broke out on 14 June 2017 is currently subject to both a criminal investigation, and a review of the UK's fire and safety regulation.
An interim report of the review released in December 2017 revealed that safety regulations for high-rise buildings are "not fit for purpose".
"The project is long-term and open-ended, and could ultimately be put to a number of uses," Bob Trafford, a researcher at Forensic Architecture, told Dezeen.
"We only hope that offering our platform as a public resource will support investigations and analysis across civil society, in line with Forensic Architecture's foundational belief that the interests of transparency and democratic accountability are well served by a strong non-state capacity for forensic analysis and investigation," he added.
"We have not to date been approached by the public inquiry, but we do have experience of working with parliamentary inquiries, UN commissions of inquiry and legal processes."
Forensic Architecture works to develop "counter forensic" techniques that can be used to reveal human rights violations. Previously it has worked with groups including Amnesty International and Sea Watch to present legal cases.
Previously the group created a digital reconstruction of the Saydnaya detention near Damascus, which was use to torture political prisoners. Forensic Architecture worked with Amnesty International to record and expose conditions in the prison.
An exhibition of the group's research has just opened at the Institute of Contemporary Art in London.
