It's painful to do the copy/paste + google workflow to find related content on a mobile device. (Do you even think it's a real pain?)

And our solution:

(As a quick background, we have a technology that extracts concepts, people, locations and organizations from text. Our solution is currently based on that tech, but we are open to everything. Feel free to check out the demo: http://www.factyle.com/speedread)

So, the solution :)

1) Tapping on the text would automatically select the person (Barack Obama), location (New York city), phrase (atomic reactor). -- A small menu would appear with options: "Related articles", "Google search", "Images", "Wikipedia

2) An optional meaning bar at the bottom of the screen with people (matched with their twitter+linkedin account) and the most important concepts. Tapping on a person or concept would yield the same options as above: "Related articles", "Google search", "Images", "Wikipedia. (the bar could also be used as a navigation tool)

(Another note: given textual context, we are able to match people to their twitter accounts with a very high confidence rate. This is not magic :) We also hope to extend the algorithm to linkedin & facebook, but it's harder)

Thank you so much for your feedback. We are struggling right now to find our customers and validate our assumptions. Any help is greatly appreciated

Thanks, Marc & Temo
