Anyone understands this
The SIGNA AI assistant

Ask it anything. It cites everything.

Every case file comes with a built-in assistant that goes deeper than the summary, without ever leaving official sources behind.

Explains any filing in plain English
Ask “what does this mean?” on any case file and get a direct answer: no jargon, no guessing.
Compares against a company's own history
Ask how a transaction stacks up against a company's past filings, and the assistant pulls the real history and compares it for you.
Teaches you an unfamiliar term
Don’t know what a Form 4 or an SDN designation is? Ask, and get a clear definition in context.
Always cites its source
Every answer links back to the exact official filing it came from. Nothing is stated without a source.
Illustrative example
Is this a big trade for this insider?
Relative to their existing holdings, this purchase represents about 0.2% growth in their direct position: a modest, not unusual, addition. This is also their fourth open-market purchase in the past two years, all disclosed the same way.
