Riducta: Choose what the AI sees. Get your data back after.

Hi Product Hunt! I'm Jihane, co-founder of X20 Digital Trust Services — the team behind Riducta. We kept running into the same problem: paste a document into ChatGPT or Claude, and you're also pasting a client's name, IBAN, or case number you really shouldn't be sending. Riducta helps you catch that before it reaches the AI — upload one file or several, it detects tax codes, IBANs and more in supported formats, you confirm or add the names to mask, check the result, then paste the reply back into Riducta to get your real data back. With Claude it uses roughly half the tokens of uploading the same PDF directly (median on 20 public documents, official Anthropic count). Everything runs in your browser — your files never reach our servers. Free to start, no signup. Would love feedback, especially from anyone handling sensitive documents (legal, HR, consulting) — that's who we built this for. ChatGPT and Claude are trademarks of OpenAI and Anthropic; Riducta isn't affiliated with them.
