Read the Terms of Service

Bring the AI service you already use, whether that's an API key for an OpenAI-compatible, Gemini or Claude service, or a ChatGPT subscription through Codex sign-in. Miffan doesn't bundle a model. Your chats and settings stay on your phone.

Chat like a messenger

Each AI partner is one ongoing chat. There's nothing to start, no model to pick and nothing to tune.

One partner, one conversation. Your history with a partner reads as one timeline across days. Behind the scenes Miffan keeps topics apart, so long chats stay quick and on point.
Ask several things at once. Unrelated questions run in parallel, and each reply quotes the message it answers.
Change a partner by telling it. "Keep your answers shorter" adjusts its preferences. Every change to a partner's settings or memory is linked to the message behind it, kept in a history and can be undone.
See what AI knows about you. Each memory shows where it came from, and you can delete it at any time.

Let your partner use your computer · new in 4.0

Connect a Mac or Linux desktop over SSH, including over Tailscale, and your partner can open apps, type and click on it while you watch from your phone.

One shared screen. View and control the desktop from your phone. Touch the screen and you take over right away.
You stay in charge. By default the partner asks before every action. Each approval is recorded in a permission history that stays even if you delete the chat.
Guided setup. Easy chat walks you through connecting a computer, checking that it's ready and handing it to a partner.

Supported desktops: macOS, Linux with wlroots-based Wayland (such as niri, Sway or Hyprland), and X11. GNOME and KDE aren't supported yet.

Professional mode when you want every option

Switch to the professional interface at any time. It uses the same data as easy chat.

Combine official APIs, compatible gateways, self-hosted endpoints and a Codex subscription.
Give each assistant its own prompts, model parameters, memory, MCP servers, Skills and web search.
Run a local Linux workspace on the phone, or let assistants work on remote servers over SSH with files and a terminal.
Use voice input and output, translate selected text in any app, and chat from a browser on your network.

The feature matrix lists every supported provider, search service, speech engine and tool.

Characters with feelings

Choose a Miffan rice bowl or the blue whale girl. Their expressions follow the conversation: they eat while you wait, get dizzy while the AI reasons, smile when a reply arrives and doze off at night.

Get started

Download the latest APK from GitHub Releases. Official builds are for arm64-v8a devices on Android 8.0 or later.
On first launch, connect an AI service with an API key or sign in with a supported account.
Start chatting.

You can back up to WebDAV or S3-compatible storage, and import data from RikkaHub, Chatbox and Cherry Studio. Prompts, attachments and tool data go only to the services you configure; see PRIVACY.md and SECURITY.md.

Project history

Miffan started as a fork of RikkaHub, an open-source Android LLM client, and has since grown into an independent app.

When	Release	What changed
Aug 2026	2.4.10-miffan.1	Forked from RikkaHub 2.4.10 and renamed Miffan, with its own app ID so it installs alongside RikkaHub. Added ChatGPT subscription sign-in through Codex.
Aug 2026	2.4.10-miffan.5	The animated Miffan bowl characters arrived.
Aug 2026	3.0.0	Moved to Miffan's own version numbers, independent of RikkaHub releases.
Sep 2026	3.1 – 3.3	First-run setup, encrypted credentials, persistent reply branches and the blue whale girl.
Sep 2026	3.4	Remote SSH workspaces.
Oct 2026	4.0	Easy chat and letting your partner use your computer.

Miffan still takes in selected RikkaHub improvements. Each one is reviewed and listed separately in the release notes (see the upstream sync policy). Upstream copyright and attribution are kept as the license requires. Miffan is not an official RikkaHub release.
