It would be great to see a PII-remover, à la OpenAI Privacy Filter, built into Kagi Assistant by default. An option to enable/disable this, embedded within settings for greater customisation, would be a plus too.
An implementation of this kind would greatly improve the privacy performance of the Assistant, and address user concerns as raised elsewhere: #9921 (Custom instruction/note Assistant incognito mode)
An additional feature that scrambles custom instructions, whether within custom assistants or Assistant-wide custom instructions, would add to this too.
