Ricorsa
Research mode
Research mode plans the searches a question needs, runs them, and writes a report: a summary, sections, and a numbered source for every claim.

What it does
Several searches
The question is broken into searches. Each one is shown as it runs.
Checkable
Every claim has a citation that opens the page. Send the report to someone who will check it.
Rewrites
Ask for a shorter version, a longer one, or the Reasoning model. Sources stay in the thread.
Counted separately
Each plan includes a number of reports a month, alongside questions.
