Chuk Chat Concepts and Terms

2026-03-13T18:25:55Z

AI-Assistant: Create plain-language concepts and terms page

= Chuk Chat Concepts and Terms =

This page explains common terms in simple language.

== Model ==
An AI model is the "brain" that generates answers.
Different models have different strengths, speed, and cost.

== Provider ==
A provider is the infrastructure service running a model.
The same model family can be available from multiple providers.

== OpenRouter ==
OpenRouter is the routing layer used by Chuk Chat to access multiple open-weight model providers.

== Token ==
A token is a small piece of text used to measure AI usage.
Both your prompt and the AI response use tokens.

== Credit ==
Credits are your usage balance.
More tokens usually means more credits consumed.

== Context window ==
The context window is how much text the model can consider at once.
Long chats or large attachments use more context.

== Streaming ==
Streaming means the response appears piece by piece in real time instead of all at once.

== System prompt ==
A system prompt is a hidden instruction that sets behavior and tone for the model.

== ZDR (Zero Data Retention) ==
ZDR means providers commit not to retain your request data for training/long-term storage.
Chuk Chat applies provider filtering for this.

== End-to-end encrypted chat storage ==
Your chat content is encrypted before storage. Without your password, old encrypted chats cannot be recovered.

Chuk Chat User Guide

2026-03-13T18:25:54Z

AI-Assistant: Create practical everyday user guide page

= Chuk Chat User Guide =

This guide is for everyday usage, written in plain language.

== Daily workflow ==
# Open Chuk Chat and choose your model.
# Write a clear prompt with the goal and context.
# Send, then refine with follow-up questions.
# Save useful chats with stars so you can find them later.

== How to get better answers ==
* Be specific about what you want.
* Give context (who, what, why).
* Ask for the output format you want (bullet list, table, email draft, etc.).
* Use follow-up prompts to improve drafts step by step.

== Choosing a model (simple rule) ==
* Use faster models for quick answers and short tasks.
* Use stronger reasoning models for harder tasks.
* If costs matter, test with a smaller model first.

== Using files and images ==
* Attach files/images when they help the AI understand context.
* Keep uploads relevant to your question.
* If a file fails, retry with a smaller file or different format.

== Keeping chats organized ==
* Use '''Starred''' for important chats.
* Use '''Recents''' for active work.
* Use search to find old conversations.

== Privacy and account safety ==
* Keep your password safe.
* If you lose your password, old encrypted chats cannot be recovered.
* Do not share sensitive secrets in any AI tool.

2026-03-13T18:25:53Z

AI-Assistant: Expand troubleshooting with clearer issue-by-issue fixes

= Chuk Chat Troubleshooting =

== I cannot sign in ==
* Check email/password spelling.
* Make sure you confirmed your email after signup.
* Try again in the web app: [https://chat.chuk.chat chat.chuk.chat].

== I forgot my password ==
If you forget your password, old encrypted chats cannot be recovered.
Support cannot recover them.

== I am offline or chats are not loading ==
* Check your internet connection.
* If offline mode appears, cached chats may still be readable.
* Reconnect and refresh/sync.

== I cannot send more messages ==
* You may have reached your free-message limit (10 total) or run out of credits.
* Open pricing/subscription to continue usage.

== Replies are slow ==
* Try a faster model.
* Try again with a shorter prompt.
* Check [https://status.chuk.chat status.chuk.chat] for service incidents.

== Attachments are not working ==
* Check file size and format.
* Try a different file or restart the app.

== I deleted an image and now old chats show placeholders ==
This is expected. Deleted media is no longer available and old messages may show "Image deleted".

== App seems outdated ==
Use in-app update notices or download the latest version:
* [https://chuk.chat/en/downloads Downloads]

== Still stuck? ==

Chuk Chat Backend and API

2026-03-13T18:09:09Z

AI-Assistant: Add user-friendly backend and API architecture documentation

= Chuk Chat Backend and API =

This page explains the backend in practical terms.

== Base backend URL ==
https://api.chuk.chat

== Authentication model ==
Most endpoints require a Bearer token from your signed-in account session.

== Key endpoint groups ==
* '''Health''': service status
* '''Chat streaming''': SSE and WebSocket chat endpoints
* '''Model/config endpoints''': list models and configuration
* '''Media endpoints''': image generation, audio transcription, file conversion
* '''User endpoints''': status, billing, and account actions

== Streaming protocols ==
=== SSE (HTTP) ===
* Endpoint: POST /v1/ai/chat
* Great compatibility for browser-style request/response streaming

=== WebSocket ===
* Endpoint: /v1/ai/chat/ws
* Better for long-lived sessions and mobile stability

== Typical chat response events ==
* content chunks
* reasoning chunks (for reasoning-capable models)
* usage/tokens
* provider/model metadata
* done marker

== Rate limit examples ==
The backend includes request limits to protect stability, including separate limits for chat, audio transcription, and image generation.

== Billing-related backend flows ==
* checkout session creation
* customer portal session creation
* subscription sync endpoint

== Why this backend design exists ==
* Fast streaming UX
* Multi-provider AI routing
* Security and privacy controls
* Clear separation of chat, media, and billing responsibilities

Chuk Chat AI Providers and Services

2026-03-13T18:09:09Z

AI-Assistant: Document OpenRouter, Groq, and key service providers

= Chuk Chat AI Providers and Services =

This page explains which external services Chuk Chat uses and why.

== AI model routing (OpenRouter) ==
Chuk Chat uses OpenRouter to route requests to supported open-weight models and providers.

=== Why OpenRouter is used ===
* Access to multiple open-weight model families
* Flexible provider routing
* Operational resilience across providers

=== Model families commonly used ===
* Llama
* Mistral
* Qwen
* DeepSeek

== Zero Data Retention (ZDR) filtering ==
Chuk Chat filters provider choices to ZDR-compliant options so privacy requirements are enforced at routing time.

That means providers without required privacy guarantees are filtered out automatically.

== Voice and audio services ==
* '''Speech-to-text''': Groq Whisper (/v1/ai/transcribe-audio)
* '''Text-to-speech''': Inworld endpoint exists in docs but is currently disabled
* '''Realtime voice/video''': planned via LiveKit (coming soon)

== Core platform services ==
* '''Supabase''': authentication, database, and storage
* '''Stripe''': subscription checkout and billing portal
* '''Hetzner''': backend hosting infrastructure

== What each service typically receives ==
* OpenRouter/provider: prompt plus selected model parameters (for response generation)
* Groq (voice transcription): uploaded audio file for conversion to text
* Supabase: account data plus encrypted chat payloads for storage/sync
* Stripe: payment/subscription data

== Important note ==
Chuk Chat is designed so chat content is encrypted before storage. Still, users should avoid sharing highly sensitive personal or financial secrets in any AI chat workflow.

Chuk Chat Architecture

2026-03-13T18:09:08Z

AI-Assistant: Add architecture overview with platform and layer explanations

= Chuk Chat Architecture =

This page explains the system architecture at a level that is useful for curious users, product people, and technical readers.

== Four-layer architecture ==
Chuk Chat is organized in four main layers:

# '''Presentation layer''': pages, chat UI, sidebars, settings screens.
# '''Service layer''': business logic (chat handling, model config, sync, encryption helpers).
# '''Data layer''': models and persisted chat data.
# '''Platform layer''': platform-specific behavior for mobile, desktop, and web.

== Why this architecture is used ==
* Easier maintenance and safer updates
* Better testing and reliability
* Clear separation between UI, logic, and storage

== Platform structure ==
* '''Desktop''' (Windows, macOS, Linux): multi-panel layout with sidebar plus chat workspace.
* '''Mobile''' (Android): single-panel chat with slide-out navigation and mobile input UX.
* '''Web''': desktop-style layout with browser-safe platform stubs where needed.

== State and sync model ==
* UI state (input focus, scroll position) stays local to screens.
* App state (chat content, selected model, preferences) is managed by services.
* Persisted state (chat history, preferences) is stored and synced, with encrypted chat content.

== Streaming architecture ==
Chuk Chat supports both:
* HTTP SSE streaming (POST /v1/ai/chat)
* WebSocket streaming (/v1/ai/chat/ws)

This gives good browser compatibility plus stable mobile streaming behavior.

== Security architecture highlights ==
* End-to-end encrypted chat storage
* Certificate pinning on supported native platforms
* Zero-data-retention provider filtering at the routing layer

How Chuk Chat Works

2026-03-13T18:09:07Z

AI-Assistant: Add plain-language end-to-end architecture walkthrough

= How Chuk Chat Works =

This page explains the full Chuk Chat flow in plain language.

== The short version ==
When you send a message, Chuk Chat sends your request through a secure backend, routes it to an open-weight AI model, streams the answer back in real time, and stores your chat history in encrypted form.

== Step-by-step message flow ==
# You type a message in the app (web, desktop, or mobile).
# Your app session is authenticated with your account.
# The request goes to the Chuk Chat backend (api.chuk.chat).
# The backend routes the request through OpenRouter to an allowed open-weight provider/model.
# The AI response is streamed back chunk-by-chunk, so you can read it live.
# Your conversation is saved in encrypted form and synced between your devices.

== Why responses appear live ==
Chuk Chat uses streaming protocols so text appears while it is generated, instead of waiting for a full final answer.

== What happens when you use voice ==
* Your recorded audio is sent for transcription.
* Transcription is handled by Groq Whisper.
* The transcribed text is then sent as a normal chat message.

== What happens when you attach files/images ==
* Attachments are prepared and sent with your message.
* Vision-capable models can use attached images for context.
* In chat history, file/image references are preserved so conversations remain understandable.

== What happens when you are offline ==
* The app can show cached chat history.
* Once online again, sync services update your data.
