Beta on TestFlight, iPhone only

Your AI assistant runs on your iPhone.Turn on airplane mode and keep talking.

Elren plans your day, changes your calendar and remembers what you tell it. The model runs on your phone's chip, so you can use it with no signal and no token limit.

Join the beta See how it works

A chatbot answers questions.Elren also does the work in your apps.

Works with no signal

Use Elren on a plane, in the subway or abroad with roaming off. The model, your memory and your calendar all live on the phone.

Gets better the more you use it

Correct Elren once and the next reply uses the correction. Turn on cloud learning and it also trains a personal layer on your examples, from once a week up to once a day.

I run in the evenings now, not mornings.

Updated. I'll plan your runs after 18:00.

memory replaced: "runs in the morning"

Your tokens never run out

Cloud assistants bill by the token, so a limit can stop you mid-task. Elren uses your phone's chip, and you can send as many messages as your battery allows.

Tokens per monthno limit

Messages per dayno limit

Fee per message$0

Web search calls a paid service, so it has a cap of 100 searches a day.

Connected to the apps you use

Ask for an outcome and Elren uses the right app. It marks a task done only after that app confirms it, and it sends email only after you approve the exact message.

Sign-in and plansStores an Apple ID reference and your plan state.

Search proxyHides the search key and applies the daily cap.

Context

Elren collects the memories, events and todos that fit your request.

Decision

The model on your phone picks a tool or writes a reply. Text from mail and web pages reaches it marked as untrusted.

Checks

Code validates the call, compares dates with weekdays and blocks repeats. A cut-off call never runs.

Result

iOS or Gmail returns what happened, and that result becomes the card you see.

Your memory updates right away.Your personal model updates on a schedule.

Memory stores facts. The personal layer teaches the model how you like things done. You decide if it runs, and you can reset it at any time without losing your memories.

1. Opt inYou chooseCloud learning stays off until you turn it on. Your phone prepares examples from your chats and corrections, and you send them with a tap.

2. UploadEncrypted storageYour phone sends the examples over TLS. The server stores them with AES-256 and deletes them after 7 days.

3. TrainA pod just for youA temporary GPU pod trains a small adapter on your examples, and Elren destroys the pod after the job.

4. TestA test before releaseThe adapter must beat the base model on examples it never saw and pass a behavior test. Otherwise Elren discards it.

5. InstallBack on your phoneYour phone checks the file's hash and loads the adapter. You can roll back to the previous version.

If you turn learning off, Elren cancels any running job and deletes your uploaded examples.

Questions

Which iPhones can run Elren?

The Compact model needs about 6 GB of memory, which means iPhone 14, iPhone 13 Pro or newer. It also needs about 3.7 GB of free storage. The Large model needs about 8 GB of memory and 6.7 GB of free storage. The app checks your phone before it downloads anything.

What leaves my phone?

Web searches go through Elren's proxy. Gmail requests go to Google. Sign-in and plan checks go to Elren's server, and the app downloads its models once from Hugging Face. Your training examples leave only if you turn on cloud learning.

Does it match the largest cloud models?

No. Elren runs a model with 4 to 9 billion parameters, small enough for a phone. Use it for your schedule, tasks, mail and notes, and use a large cloud model for deep research.

Will it drain my battery?

Long sessions use more battery and warm the phone, because the model runs on the phone's GPU. Short requests cost little.

How do I delete my data?

Settings has one action that wipes the phone's local data and another that deletes your account and everything on the server. You can also view, correct or forget single memories in the Memory tab.
