Weave FAQ.
Answers about on-device AI, privacy, memory, and pricing.
About the product
What is Weave?
Weave is a journaling app where the AI runs on your phone, not in a data center. You can speak or type; the app reflects on what you wrote and notices patterns across weeks and months. The point is a notebook that remembers - without needing a server to do it.
How is Weave different from Day One, Daylio, or Stoic?
Day One is a beautiful long-form journal without AI memory. Daylio is mood-tracking built around quick check-ins. Stoic combines prompts and mood but doesn't connect entries across time. Weave sits between those - a reflective companion with semantic memory that links entries written months apart, even when the wording is different. And a difference beneath the surface: the AI runs on your phone, not on a company's server.
Does Weave work offline?
Yes - the app is fully offline after the first-launch model download. Voice transcription, reflection generation, and semantic search all run on your phone, even in airplane mode.
What languages does voice journaling support?
English only at launch. Additional languages will come in later releases as on-device speech-to-text is tuned per language.
What AI models does Weave use?
The AI that transcribes your voice and reflects on your entries runs entirely on your phone - no cloud call, no model provider we pay per token. Specific models can evolve as on-device inference improves; the promise is that whatever ships on your device, that's what does the work.
Why on-device
Why on-device?
Weave started as a web app with cloud AI. That works, but every entry you write has to leave your phone to reach the model. Moving everything on-device means your phone is the server - the only architecture where "private journal" means what it sounds like. Read the longer essay at /essays/why-on-device for the full reasoning.
Memory and reflections
How does Weave remember what I wrote?
Every entry becomes a mathematical representation of its meaning, stored locally on your phone. When you write something new, Weave searches across every past entry by meaning, not just keywords - that's why "I'm overwhelmed at work" can connect to "the pressure is crushing me" written three months ago. All of the searching happens on the device.
Privacy and trust
Who can read my entries?
No one - because they're not on our servers. Entries live in a local database on your phone; no company employee has technical access to your writing.
Do you sell or share my data with advertisers or other companies?
There isn't any of your data on our end to sell. Your journal, your audio, your reflections all stay on the device - there's no cloud copy for us to monetize, share, or lose in a breach.
Is my data used to train AI?
This isn't a policy - it's architecture. Your entries never leave the phone, so there's nothing to feed into a training pipeline.
Is my journal safe with an early-stage app?
A cloud journal requires you to trust the company. Weave requires you to trust your phone. Your journal doesn't depend on our uptime - if we disappear tomorrow, the app you already installed keeps working, and your entries stay yours. You can export or delete your entries at any time.
Pricing and launch
How much does Weave cost?
Weave Pro is $3.99/month, with a 7-day free trial to start - no card required upfront. After the trial, continued use requires the subscription; there's no separate free tier. Billing is handled through your Apple ID and renews automatically until you cancel.
Where can I get Weave?
Weave for iOS is live on the App Store - install it from tryweave.app or search "Weave journal" on the App Store. Android is still in progress; drop your email on the /beta page and we'll send you the invite when it's ready.
