Design Settings

Settings

Settings holds what changes rarely: where chat runs, the provider address, the default model, the key, and the save folder. Release builds block screenshots and screen recording on this screen, so a key never lands in a capture.

Top bar

Box	What it holds	Why
Back arrow	Returns to the main screen	Standard Android navigation. The phone's Back gesture does the same.
Title	"Settings"	Names the screen
Done	Returns to the main screen	A plain exit for users who look for a word rather than an arrow. Done does not save. Each card has its own Save.

Under the title, one line reminds the user that models and keys stay on this device.

Mode switch

Box	What it holds	Why
Chat, Image, Video	A segmented button	Each mode has its own provider, model, and key, so Settings edits one mode at a time

Chat runs card

This card appears only under Chat.

Box	What it holds	Why
On this phone, OpenRouter	A segmented button	Chooses where chat replies come from. The choice applies at once.
Model name and state	The chosen on-device model, and whether it is loaded	Shows what will answer the next message
Engine line	"the faster build for this processor" or "the standard build"	Explains the speed a phone gets. The app chooses the build itself.
Manage models	Opens the Model Manager	Downloads, chooses, and deletes on-device models
Context size	2048, 4096, 8192, or 16384 tokens, default 8192	A larger context remembers more of the conversation and needs more memory
Processor threads	Automatic, or 2, 4, 6, or 8	For speed testing on a particular phone. Automatic suits nearly every phone.
Show the model's thinking	A checkbox, off by default	Lets models such as Qwen3.5 and Gemma 4 think before they answer. Answers then take longer. The thinking appears apart from the answer, and the model does not see it again later.

The model name, Manage models, and the two dropdowns appear only while On this phone is selected. A note under the card says that the OpenRouter settings below stay saved, because Suggest setup in API CALL still uses them.

Create from chat card

This card appears only under Chat.

Box	What it holds	Why
Create images and videos from chat	A checkbox, on by default	Turns each chat reply into a plan. A plan for a picture, an edit, or a video shows as a job card. Off brings back plain chat.
Note	Says that thinking is not shown while this is on	A plan must be a structured reply, so the model cannot think out loud first

Web search card

This card appears only under Chat.

Box	What it holds	Why
Allow web search	A checkbox, on by default	Lets the chat look up current facts before it answers. Off keeps every message on the phone.
Note	Says that search words leave the phone and that replies list their searches	The user knows what is sent and where
Tavily API key	A password field, optional, with a status line	Without a key the chat searches Wikipedia. A free Tavily key searches the whole web. The key is encrypted and goes only to Tavily.
Save key, Remove key, Get a key	Buttons	Get a key opens Tavily's sign-up page in the browser

Memory and history card

This card also appears only under Chat.

Box	What it holds	Why
Summary	How many memory instructions are on, such as "2 of 3 memory instructions are on."	Shows at a glance what every chat starts with
Edit memory	Opens Memory	Standing instructions change rarely, so they live one screen deeper
Save chat history	A checkbox, on by default	Off keeps new chat messages only until the app closes. Images and videos are saved either way.
Clear chat history	A red button with a confirmation	Deletes every chat message on the phone. Images, videos, and memory stay.

Provider card

Box	What it holds	Why
Card title	"OpenRouter, Chat Completions" or "Replicate, Predictions"	Names the protocol this mode speaks
Protocol note	Explains that a new provider must speak the same protocol	Changing the address alone cannot add a provider with a different interface. The note prevents a confusing failure.
API base URL	The provider address	Allows an OpenRouter-compatible chat service. HTTPS is required.
Model ID	The exact model for this mode, with a default reminder for Chat	Sets the model the main screen uses
Saved models	A dropdown that copies a saved model into the Model ID field	Saves typing a long ID

API key card

Box	What it holds	Why
Use text LLM API key	A checkbox on Image and Video	Reuses the chat key when both modes use the same provider address
Use image API key	A checkbox on Video, checked by default	Video and images both run on Replicate, so one key covers both. Only one reuse box can be checked.
API key	A password field with a show or hide eye, plus a status line	The status line reads "Saved securely. Leave blank to keep." once a key exists. A blank field keeps the stored key, so saving other changes never erases it. The field grays out while a reuse box is checked.

The card refuses to reuse a key across different provider addresses, because each key works only at its own provider.

Save row

Box	What it holds	Why
Save settings	An orange button, such as "Save image settings"	Commits this mode's provider, model, and key together
Remove key	A red text button with a trash icon	Deletes the stored key after a confirmation dialog. The dialog notes that this does not revoke the key at the provider.
Status line	"Saved.", "Key removed.", or the reason a save failed	Confirms the result in place

SpicyAPI card

On the Image and Video pages. It holds the optional SpicyAPI key, which starts with sk-spicy-, with Save key and Remove key. The key has its own encrypted slot, so it never replaces the Replicate key, and it goes only to api.spicyapi.com. With a key saved, SpicyAPI's four text-only models in the model lists can generate: Adult picture from words (Spicy Image 1 and Spicy Image 1 Pro) and Adult video from words (Spicy Video 1 and Spicy Cinema 1). They take no photo.

OpenRouter card

On the Image and Video pages, below the SpicyAPI card. It names the OpenRouter models in that list and explains that they use the OpenRouter key saved for Chat, which goes only to openrouter.ai. An orange line says whether they are ready: "Ready: your OpenRouter key is saved.", a request to save the key under Chat, or a note that Chat uses another address. The card has no key field of its own, so one OpenRouter key serves chat, pictures, and video.

Image history and Video history cards

The Image and Video pages each show how many cards their list holds, with Clear image history or Clear video history. After a confirmation, every card of that kind and its file in private storage are deleted, including photos added from the phone. Copies saved with Save, the originals in the phone's gallery, chat, and memory all stay. A job that is still running must finish or be canceled first.

Save folder card

Box	What it holds	Why
Current folder	The folder name, or "Not chosen yet"	Shows where Save puts files
Choose folder	Opens Android's folder picker at the current folder	Changes the folder without starting from the top of storage. Android remembers the permission, so the folder works after a restart.

| Save automatically | A switch, on at first: "Save every finished picture and video here automatically" | Keeps every new result without a tap. It starts once a folder is chosen and covers results made from then on, not older ones. |

Save makes one copy of each result. Tapping Save again, or saving a result that was already saved automatically, makes no second copy; the message says "Already saved in" the folder, with Open folder, and the button reads Saved.

Open folder opens the save folder in the phone's file manager. Android lets the user pick which file manager when more than one is installed. The message after each Save offers Open folder and Change as well.
