A spreadsheet remembers numbers. It does not remember why you changed the price in March, or what three buyers said about trust, or that you were in Communicate while the offer was still vague. Idea Bank is the Pro workspace where that history lives for one business idea at a time: which step you are on, what you tested, what you learned, and what blocks the next sale.
Idea Bank is not on Free. Free is unlimited reads on your draft. When someone says "open Idea Bank" on I2S OS, they mean upgrade to Pro and work the path there, not a free tab beside the report.

Names gaps. Holds proof.
What you do there
For each idea you commit to, you get one workspace:
- Which step you are on and what blocks the next step
- Completed worksheets (the forty-nine named tools: buyer profile, offer shape, call log, and the rest)
- Notes, decisions, and sales attempts with dates
- Guided worksheet help when one worksheet is hard, not when you want open-ended strategy chat
- Exports from saved work when you need a brief or outline for a buyer
A co-founder can open it and see what was tested without trusting your memory or scrolling Slack.
How it connects to clarity on drafts
The usual path:
- Clarity on drafts: which step, gaps, one action
- Do the action in the real world
- Pro: open Idea Bank for the idea you are executing
- Work worksheets for the current step; use guided help on the stuck field
- Get clarity again after progress and check whether the stage moved
the report is the mirror. Idea Bank is the bench where you keep what the mirror pointed at.
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.
See what to save at each step for how proof compounds into repeatable sales.
Multiple ideas
Pro supports more than one idea in Idea Bank. You should still give one idea Convert focus this month. Park the others with why they lost and when to revisit.
On Free, get clarity on each draft until you commit to Pro for the idea you will execute.
What a good week looks like
Monday you open the idea in Idea Bank and see you are still in Clarify. The buyer field is empty. You schedule four calls. Tuesday and Wednesday you paste buyer quotes into the worksheet, not into a random doc. Thursday you draft the offer in Create using their words. Friday you read your updated draft again and check whether the report moved to Configure or still flags the buyer.
That week is boring on purpose. Boring means the proof is visible. When a co-founder asks "where are we," you send a link, not a speech.
Questions
Can I use Idea Bank without guided help?
Yes. Many fields are fill-in-the-blank once you have buyer contact. Guided help is for the field you are avoiding.
Does Idea Bank replace Notion?
Not for everything. Use Notion for internal ops if you like. Use Idea Bank for proof on the path to sales. See Idea Bank vs. spreadsheets.
