Free tools
Genuinely free, genuinely useful, and no account required. Use them, take the answer and go. If you want the finished document afterwards, Vizivo is there, but you are not obliged.
More are planned. If there is a calculation you keep doing by hand, tell us at support@vizivo.ai and it may well be next.

Vizivo generates the finished documents: invoices, quotes, proposals, business plans, terms and privacy policies, personalised from a profile you fill in once. The free plan includes 30 credits a month and needs no card.
