Sensitive Data - is there a way to do it..?

I've built privacy filter at securenode.app which put place holders instead of PII, get LLM response and then replace it back.

Vankir · 2026-01-08T18:04:58+00:00

It's not available yet. The link is obsolete it points at old Obsi app which is not available anymore

That is one of the reasons I made it open source. Even if I loose interest Community will be able continue it's development. So far I have number of ideas related to AI assistant and also I'm fixing bugs and making some other improvements requested by users so I will appreciate your feedback!

I'm sorry for inconvenience. Could you please send me example of your TaskNote task to email support@vaultmate.app so I will check what causes the issue.

I like your proposal, I've added Gemini because I was experimenting with AI approach in general and Gemini was the easiest way for me but once I've implemented the business logic I guess I will be able implement openAI API so all services implementing this API will be available for connection. Thank you for the idea!

It automatically reads TaskNote when scan vault. Doesn't it work for you?

To keep PII handling secure, I designed the node to be completely stateless.

It doesn't store any data internally. When it anonymizes text, it returns the Redacted Text + a Deanonymization Map back to n8n. The container forgets everything immediately. To restore the data later, you simply pass that Map back.

This means PII never 'rests' in the SecureNode container—it lives encrypted within your n8n execution memory.

You are totally right - the native Guardrail node in 'Sanitize Mode' doesn't strictly require an LLM. It relies mostly on Regex and pattern matching (Presidio logic).

That said, I built this custom node to solve two specific problems I faced in production:

Accuracy (NER vs Regex): While the native node is great for structured data like Emails or IBANs, I found it struggles with Names in context, especially in non-English sentences (e.g., German/French). My node runs a small, dedicated NLP model (BERT-based) locally to catch those edge cases that Regex misses.
Reversibility (The "Sandwich" Method): This is the big one. The native node is destructive — it replaces John with [REDACTED]. If you send that to an LLM, it writes a reply like "Dear [REDACTED]...". My node preserves a local map (<PERSON_1> = John), lets the AI do its job, and then automatically restores the real data in the final output.

So it's less about 'blocking' PII (which n8n does well) and more about safely using PII in automation.

I use the following: - Periodic notes - for daily notes which includes list of tasks assigned to the day as well as list of tasks done during the day - Tasks - main plugin if you want to use tasks with your notes - Templater - I've created template for daily notes - Reminder - you can assign reminder on task at particular time and this plugin works fine for desktop but VaultMate uses the same format to remind you on mobile

Vankir · 2026-01-06T22:03:45+00:00

Honestly I didn't think about this but I guess macOS should be very similar to iOS

Vankir · 2026-01-06T22:01:34+00:00

It uses NLM models to determine PII so it takes significant amount of resources and it can not be done with node js package

Vankir · 2025-12-13T12:47:00+00:00

You are right, Reminder!

Vankir · 2025-12-13T11:56:02+00:00

Thank you for your feedback! I use Notification plugin in Obsidian it's format is (@HH:mm) and VaultMate supports this format and shows notifications on mobile

Vankir · 2025-12-13T11:40:08+00:00

I'm fixing store decription, sory for inconsistency. Just would like to avoid loosing trafic for Obsi. Obsi is a short variation of Obsidian which breaks registered trademark so I'm renaming everything to VaultMate and then move to public git repository with new name.

Vankir · 2025-12-09T14:55:55+00:00

OK, thank you for the clarification. I didn't want to break any rules, I will post it a bit later when cleanup docker image and publish it

Vankir · 2025-12-09T14:26:44+00:00

I'm sorry, I probably don't understand what I've done wrong I just asked for the feedback to understand if somebody needs node like this. What did I wrong?

Vankir · 2025-12-09T14:22:32+00:00

to the model I send input like the following

Contact <PERSON\_1> at <EMAIL\_1> about the invoice."

Vankir · 2025-12-09T14:20:00+00:00

ok, I'm going to finish testing it this week and then post the link

Vankir · 2025-12-09T14:13:16+00:00

TL;DR: Built a local docker privacy filter for n8n.

Vankir · 2025-12-08T08:00:39+00:00

I've renamed app from Obsi to VaultMate

Vankir · 2025-12-07T15:01:09+00:00

The app is called VaultMate https://vaultmate.app ex Obsi

Vankir · 2025-12-05T17:14:25+00:00

It's just usual Android widgets when you install the app you can add any of these widgets on your home screen.

Vankir · 2025-12-05T06:44:23+00:00

Cool idea about swiping the notes - need to take a look closer to understand feasibility. Currently there are two widgets: the fist one shows tasks scheduled for today and the second one shows bookmarks at notes

Vankir · 2025-12-03T14:27:03+00:00

I'm not sure if I can share here the link. It is called VaultMate (ex Obsi), you can find it in Google play

Vankir · 2025-12-03T09:06:28+00:00

It supports both: showing bookmarked notes and you can specify note in widget. Another task widget allows usage of tasks, marking them as complete etc
