Aeuro Chat

Aeuro Chat is a private AI assistant that runs entirely on your device — no cloud, no API keys, no server, and no internet connection required after the initial setup.

HOW IT WORKS

Download a compact, open-weight language model once over Wi-Fi, and Aeuro Chat runs it locally using on-device inference. The model is memory-mapped straight from disk, so it loads quickly without duplicating gigabytes of data in RAM. Once a model is downloaded, the app works permanently in airplane mode — every response is generated on your CPU or GPU, and nothing you type is ever sent anywhere.

BUILT FOR ACCURACY, NOT JUST SPEED

Small on-device models can be inconsistent on math, logic, and code unless they're guided carefully. Aeuro Chat solves this with a structured reasoning pipeline that runs before every answer: the model first decomposes your question into its core requirements, works through the necessary steps one at a time, and then double-checks its own intermediate work for mistakes before presenting a final answer. This step-by-step thought process is shown in a collapsible panel, so you can inspect the model's reasoning or just read the clean final answer.

CHOOSE THE RIGHT MODEL FOR THE JOB

Aeuro Chat ships with a curated catalog of GGUF-format models sized for your device, including options tuned for fast everyday chat, for math and logic, and for coding — from lightweight models that run comfortably on phones to larger ones for desktop. Downloads are resumable and checksum-verified, so a lost connection or app restart never leaves you with a corrupted model file. Storage use is shown clearly, and models that need more RAM than your device has are marked so you don't download something that won't run well.

KEY FEATURES

• 100% offline inference — every response is generated on-device; your conversations never leave your phone or PC

• Step-by-step reasoning shown in a collapsible "thought" panel, with a clean final answer always visible

• A curated model catalog covering fast chat, math/logic, and coding use cases

• Resumable, checksum-verified downloads with clear storage and RAM guidance

• Persistent chat history with full-text search, rename, pin, and delete

• Personas — switch instantly between Problem Solver, Code Reviewer, Math Tutor, Essay Writer, and more, each with its own tuned system prompt

• Document chat — attach a PDF, TXT, or Markdown file and ask questions grounded only in its content

• Markdown rendering and syntax-highlighted code blocks with one-tap copy

• Adjustable generation settings — temperature, response length, and context window — with plain-language presets (Precise, Balanced, Creative) for anyone who doesn't want to tune raw parameters

• A persistent "runs locally" privacy indicator so you always know your data isn't leaving the device

• Smooth, responsive interface that never freezes while a response is generating, with light and dark themes

TOTAL PRIVACY, ZERO ONGOING COST

There are no accounts to create, no analytics or telemetry, and no data collection of any kind. All computation happens on your own CPU, GPU, or NPU — nothing is uploaded, logged, or shared with us or anyone else. Once you've downloaded a model, Aeuro Chat costs nothing to run and needs no connection at all, forever. You could use it on a plane, in a basement with no signal, or anywhere else with zero connectivity and it works exactly the same.

WHO IT'S FOR

Aeuro Chat is for anyone who wants a genuinely useful AI assistant without handing their conversations to a cloud provider: students working through math and coding problems, developers who want a quick code reviewer without pasting proprietary code into a browser, writers who want a private drafting partner, and anyone working somewhere with limited, unreliable, or no internet access at all. If you care about keeping your questions and your data on your own device, Aeuro Chat is built for exactly that.
