Idea Bank is not on Free. Free is unlimited Analyze: the read on your draft. Idea Bank is the Pro workspace where you actually work an idea through the six steps to a sale.
If someone says "bank the idea" on I2S OS, they mean upgrade and open Idea Bank: not a free tab next to Analyze.

What you do there (Pro)
For each business idea you get one workspace:
- Which step you are on and what blocks the next step
- Completed worksheets (the forty-three named tools, buyer profile, offer shape, call log, etc.)
- Notes, decisions, and sales attempts with dates
- Brainstorm when one worksheet is hard
- Exports from saved work (briefs, outlines) on Pro
A co-founder can open it and see what was tested, without trusting your memory.
How it connects to Analyze
Typical path:
- Analyze on Free, which step, gaps, one action
- Pro: open Idea Bank for that idea
- Work worksheets for the current step; use Brainstorm on the stuck ones
- Analyze again after real progress
Analyze is the mirror. Idea Bank is the bench.
Proof vs notes
A reminder is not evidence. "Three buyers said they would pay without feature X" is evidence. If it cannot change price, scope, or message next week, it is still a sketch.
Multiple ideas
Pro supports more than one active idea in Idea Bank. Free does not include the workspace at all, run Analyze on each draft until you commit to Pro for the one you will execute.
