Find and use a tool
- Open Founder Tools.
- Search for the task, decision or tool name. Use a category such as Planning, Financial or Analysis to narrow the list.
- Read the tool's purpose and start with one real situation.
- Enter known facts. Label assumptions, estimates and the time period behind numbers.
- Review the result before using its Save, Download or Share controls.
Signed-in users can save catalogue favourites to find tools again. A favourite bookmarks the tool; it does not save the work inside it.
Check what Save means
Saving differs by tool. Business Plan Generator saves locally. Pitch Deck Generator saves an account draft. Customer Interview Toolkit keeps a local draft and has a separate Save to Deliverables action. Follow the saving guide before changing devices.
What happens next
Leave with one output you can review or test. If it changes a decision, carry the relevant excerpt into your venture evidence. AI suggestions can help draft an answer; check them against your actual situation.
Check financial currency labels
The Financial Calculator accepts a currency code beyond its common suggestions and preserves unfamiliar labels when loading saved templates. A missing label is shown as Currency not set, rather than guessed as USD. Confirm the intended currency before relying on a scenario. Changing a label never converts the amounts. Built-in calculator templates are fictional USD practice examples; they are not current market forecasts.
