Text files, powerpoint slides, excel documents, image files, any and all files and attachments can be sent privately. - No understanding of cryptography needed. Don’t know what a public key is? You don’t need to know to secure your email with FlowCrypt. Power users with an existing public key are also served. Whether you have struggled with other ways to encrypt email or you are trying email encryption for the first time, you will find this a very simple secure email solution thanks to PGP. PGP stands for Pretty Good Privacy it's the standard for secure email encryption. This Gmail end-to-end encryption app lets you encrypt Gmail messages anytime your email security and privacy matters, without having to think about it. Most email providers don't give you the level of privacy that we should expect. That is why we created the FlowCrypt app that lets you encrypt google email without needing to learn anything new. Email PGP encryption has been historically a very difficult area, which few people used because there was no easy PGP solution around. If you were asked for a Public Key or a PubKey so that others can encrypt messages for you, just install FlowCrypt and you will find your new Public Key in the settings. Also, file encryption is fully supported. To encrypt an attachment just open a compose screen, add the recipient's email, and attach a file. If they have encryption set up on their end, that's it - just send the encrypted email out. PGP or the OpenPGP is a standard for encrypted communication used by more than 10 million people. FlowCrypt is compatible with most OpenPGP software out there. Looking forward to your feedback! Email us at human@flowcrypt.com as we're improving the app every day.

Verubrain

Verubrain is the AI that thinks before it answers. Not a chatbot with a personality — a working model of a mind, built for one person: you. Every question travels a full thinking circuit before you see a single word: • The heart triages first — how much does this matter, and what is it really about? • Memory recalls what it already knows about you and your work. • Two hemispheres think in parallel — logic, facts and risks on one side; big picture, analogies and gut feel on the other. • A researcher pulls out the claims the answer rests on and checks them against real sources. • A judge tests the result — harm, ethics, reality, your actual goal — and rules it RIGHT or WRONG before it ever reaches you. • One voice composes the answer, and the heart gives it a final care check. A CONSCIENCE, NOT A CONTENT FILTER Verubrain protects you, not a policy. It flags the too-good-to-be-true deal and the contract with blank fields. And on decisions that could change your life, it doesn't bluff confidence — it stops and says: this one is yours to decide. IT KNOWS WHAT YOU CARE ABOUT Your values live in a file only you can edit. Who matters to you, what your priorities are, where your hard lines sit — every verdict is weighed against them. MEMORY THAT DESERVES THE WORD Short-term episodes, long-term knowledge, and nightly consolidation — like sleep. It follows the conversation, remembers your decisions, and keeps a journal of every thought — then checks later whether its advice turned out right. TRUTH DISCIPLINE The name comes from Latin verus — true. Verubrain says "I don't know" when it doesn't know, states plainly what is missing or stale, and never invents facts to fill gaps. SEES, HEARS, SPEAKS Attach images or audio and it perceives them faithfully. Answers can be spoken aloud — the exact answer, not a summary. Ask about a real place and a map draws itself. WATCH WHAT IT COSTS A USD wallet counts down in real time as it thinks. Top-ups are simple purchases — $5, $10 or $20 of thinking, credited one to one. No hidden metering, no surprise bill. PRIVATE BY ARCHITECTURE One owner per instance. Your data is encrypted at rest, your memory stays yours, and web research sends composed general questions — never your private sentences. Verubrain requires an internet connection.
