Banks and landlords often ask for a payslip but you don't have to share everything. Blackline AI removes tax IDs, social security numbers, bank details – or the salary itself – in a few clicks.
Tick a category — the AI finds every match in the document and blacks it out. Names, amounts, IBANs, addresses and more, in seconds.
