Easy PGP vs Kaia

Easy PGP brings PGP encryption to your phone without the usual complexity. Protect sensitive messages, verify that a message really came from who it claims, and keep your keys under your own control. YOUR KEYS STAY ON YOUR DEVICE Key generation, encryption, decryption, signing and verification all run locally. Your keys and your messages are never uploaded anywhere. There is no account and no sign-in. BUILT FOR PEOPLE, NOT JUST EXPERTS A clear interface that does not assume you already know what a keyring is. Available in 20 languages. WHAT YOU CAN DO - Generate PGP key pairs Create a new key pair with the encryption settings you want. - Import and export keys Bring in keys you already have, or export yours for backup and for use on another device. - Encrypt and decrypt messages Protect a message with a recipient's public key, and open messages sent to you with your private key. - Sign and verify Sign a message to prove it came from you. Check the signature on messages you receive. - Protected key storage Lock your key list behind a PIN or your device's biometrics. WITH THE ONE-TIME UPGRADE The upgrade removes ads and unlocks four more tools: - File encryption Encrypt, decrypt, sign and verify any file, not just text. - Password-based encryption Encrypt with a shared passphrase when you do not have the other person's key. - Encrypt and sign in one step - Decrypt and verify in one step WHO IT IS FOR Journalists protecting sources. Lawyers and doctors handling confidential material. Developers verifying releases. Anyone who would rather not hand their private messages to a third party. PRIVACY No account. No message or key ever leaves the device. Crash reporting is off by default and you can turn it on or off in settings. The app collects anonymous usage statistics to see which features are used. A NOTE ON OFFLINE USE All PGP work happens on your device and needs no connection. The free version shows a banner ad, which does need one. The upgrade removes ads, and after that the app has no reason to reach the network at all. PRICING Everything above under "what you can do" is free, with ads. The one-time upgrade removes the ads and unlocks the four extra tools listed above. No subscription, no recurring charge.

Kaia is an AI assistant that runs entirely on your iPhone. No cloud, no account, no trail. Your phone is the server. WHAT KAIA DOES Chat anywhere Ask Kaia for help with writing, ideas, summaries, drafts, explanations. The model lives on your device. The internet is optional. Bring your own search key For questions that need today's web — weather, news, recent events — connect a Tavily or Brave Search key. Their free tiers cover roughly 1,000 to 2,000 searches a month, and your key stays on your device. Off by default. Calendar that understands Ask "what's on my schedule tomorrow?" and Kaia reads from your local calendar — but only when you grant access in Settings, and only on-device. Events never sync to a server. See what you're looking at Attach a photo and ask Kaia about it. Vision runs through Gemma 4, on-device, on the GPU. Distance and directions "How far is downtown?" works without a network. Location + on-device geocoding, no map service round-trip. VOICE AND PERSONAS (Pro) Hands-free Talk to Kaia, get spoken replies. Speech recognition runs on-device. Custom prompts per chat Set a different system prompt for each conversation. Coding coach in one chat, language tutor in another, focused brainstorming partner in a third. Export your conversations Save chats as Markdown or PDF for archiving, sharing, or searching later. ZERO TRACKING. ZERO ANALYTICS. Kaia ships with zero third-party analytics or telemetry SDKs. We have no servers to see your prompts because the prompts don't leave your phone. No account, no signup, no email collection. POWERED BY GOOGLE LITERT-LM Inference runs entirely on-device through Google's LiteRT-LM runtime, accelerated on the GPU. Available models are Google Gemma 4 E2B and E4B (Gemma Terms of Use) — the E2B model also reads images for on-device vision. WHAT KAIA ISN'T Not a chatbot wrapper around a cloud API. Not collecting your data. Not asking for your email. Not subscription-priced. Built for people who want AI on their terms. REQUIREMENTS iPhone with Apple silicon. iPhone 15 Pro and later have the memory headroom for the larger models. iPhone-only — not available on iPad. Subject to Google's Gemma Prohibited Use Policy, surfaced inside the app where you actually see it.
