It helps you send, receive and store files without worry your content is getting leaked or is being used to train other people's AI models. Very important for lawyers, health care industry workers, financial firms, etc. So we don't know if it'll change your life personally or not, and let's be real we don't know if it'll change aaaanyone's life completely (it's b2b sass at the end of the day☺️) but there are people out there who have this concern relating to encryption around file transfer/storage!

@raihankhan_rk @coldvisit_ai Interesting! We'll have to check this out

Do you regularly send files to people and care about privacy? Or maybe you just want to make sure you client receives their files easily.

Either way, test out Sandra and let us know your thoughts!

Anthropic engineer:

"You're not supposed to prompt Claude. You're supposed to build a system that prompts itself."

In 45 minutes she breaks down how Anthropic builds agents that remember, learn from their mistakes, and get smarter with every run.

Worth more than any paid course you'll find on building agents.

Sandra is better than “trust me, it’s in the cloud.”

End-to-end encrypted file delivery:
encrypted before upload,
decrypted by the recipient,
not used for ads, profiling, or AI training.

Feels like privacy tools are evolving beyond just “store files safely” 👀
Now it’s becoming about who can access data, where it lives, and how much control you actually have.

1️⃣ @SandraFiles_
Interesting take on file sharing + storage.
Instead of trusting a platform with your files, encryption happens directly in the browser before upload.
So whether you’re sending large files or storing them, the bigger idea is privacy-first transfer without the usual tracking or scanning.

2️⃣ @vaultaire_app
This feels like privacy for personal data at a deeper level.
Photos, videos, and files stay local-first, with extra layers like hidden vaults and emergency access controls.
A reminder that security isn’t always just passwords.
Sometimes it’s designing for worst-case scenarios.

3️⃣ Suprbox
Probably the most interesting shift here.
As AI agents get access to enterprise data, the bigger question becomes:
how do you protect the data itself, not just the app?
Instead of giving broad access, this focuses on scoped permissions, rules, approvals, and audit trails.
Feels like privacy is moving in 2 directions right now:

For people → protect your files
For companies → protect what AI can touch

👉 What matters more to you today: convenience, privacy, or control?

Hello builders! It's Monday!
Looking to connect with more solo founders!
What are you building this week?

[Sandra @SandraFiles_]

@neerajjj6785 Hard question on X

[Sandra @SandraFiles_]

@BeeReach_io Files are encrypted before upload and remain encrypted in storage. We'd rather protect user data than monetize it.

[Sandra @SandraFiles_]

Solo founder. Paris. Building Sandra in public.

The cloud became a slot machine for our files.
I’m building the quieter alternative.
Private by design.
No noise. Just your files.
