[6] In January 2012 True Knowledge launched a major new product Evi (pronounced ee-vee), an artificial intelligence program which can be communicated with using natural language via an app on iPhone and Android.
One method involves a system of checks and balances in some ways similar to Wikipedia's, allowing users to modify or "agree"/"disagree" with information presented by True Knowledge.
[4] Then, on 17 September 2007, Octopus Ventures, a British venture capitalist firm, announced its investment of more than $1.2 million into True Knowledge, the first significant investment into the company, allowing it to further develop its website and achieve critical milestones towards bringing the True Knowledge Answer Engine to market.
[21] On 30 July 2008, True Knowledge announced it had raised another $4 million in a second round of funding from Octopus Ventures and other investors that would be used towards expanding its staff, developing new products, and moving towards a rollout within 12 months.
[25] Evi was launched to the public in January 2012 through the iTunes App Store and Android Marketplace (now rebranded as Google Play).
[27] Evi is a cloud-based Artificial Intelligence (AI) which builds upon the core semantic search technology developed by the company and adds conversation, external APIs, location sensitivity and other features.
This was announced as the first phase of phone control updates which are planned to add further functionality and deeper integration with device features.
