A core component would be standardising clauses so they could be handled individually and automatically. If you’ve already answered the clause, and the parameters (time spans, quantities) were within the range you’d set, it would be ‘green’ and could be hidden. Clauses which you had answered but are outside your criteria would be ‘amber’, and unanswered clauses would be ‘red’. As you process more agreements, your can save answers to your profile so the process becomes more optimised over time.
One concern I'd have is that the level of access I'm willing to give websites isn't always universal, even within the same category. On the other hand, there's some things I really just don't care about and whatever website can help themselves. Just something to consider.
Another component would be the ability to rigorously diff agreements as they change, only those components that change or are in some way dependant are presented for attention.
