Outgrow alternative: build calculator forms in ChatGPT instead

Outgrow is built around interactive content like quizzes and calculators. Its calculators start at $22 a month, or $14 a month billed yearly, and you build them in its editor, where its features page lists an option to upload math from Excel. CalcForms does one thing: it turns your existing Excel or Google Sheets pricing model into a live web calculator, built in minutes by chatting with ChatGPT. No new platform to learn, no template-picking, no re-entering formulas. Free, unlimited forms and submissions in ChatGPT.

Questions about switching from Outgrow

I use Outgrow for ROI calculators and lead scoring. Can CalcForms do that?
Yes. ROI calculators, lead scoring formulas, pricing quizzes. If the math lives in a spreadsheet, CalcForms builds it. Results update as your customer types in list view, and every lead arrives already scored, in ChatGPT or in the web portal on Pro.
Is CalcForms cheaper than Outgrow?
Yes for most users. CalcForms is free in ChatGPT with unlimited forms and submissions, and the Pro web portal is $12.99 a month. Outgrow calculators start at $22 a month, or $14 a month billed yearly, for 5 content pieces; unlimited content is $115 a month, or $95 a month billed yearly.
Do I need to know how to use ChatGPT to build a form?
No. You describe the form in plain English or paste the spreadsheet. ChatGPT handles the build and hands you a live URL. Most forms are done in under 20 minutes.
Can my marketing team edit the form later?
One account edits each form. A form belongs to the CalcForms account that built it, and the person signed in to that account updates it by asking ChatGPT in plain English. No developer needed.
