AI Chat

What is AI Chat?

AI Chat is a free, in-browser AI assistant that holds natural, multi-turn conversations and helps you get real work done — answering questions, writing and editing, coding, researching, analyzing data and planning. It combines a clean, modern chat interface with rich Markdown rendering, code highlighting, tables, math and diagrams, plus file and image uploads, voice input and a memory system.

Unlike a single-purpose tool, AI Chat is a platform. Eleven specialized modes tune it for general chat, research, coding, writing, business, marketing, education, data analysis, creative work, productivity and customer support — and a multi-model architecture lets it route each request to the most capable model.

How AI Chat works

You pick a mode and a model (or leave it on Auto), then type, speak, or upload a file. Your message — along with the conversation history and any remembered context — is sent to the assistant, which streams its response back token by token so you see the answer as it is written.

Responses are rendered as rich Markdown: headings, lists, tables, syntax-highlighted code blocks with one-click copy, LaTeX math and Mermaid diagrams. Everything is saved locally with search, folders and pinning, and you can regenerate, react to, bookmark or export any message. When no AI provider is connected, a built-in offline assistant gives structured, mode-aware guidance so the tool is always useful.

Supported AI models

AI Chat is built on a multi-model architecture so you are never locked into one provider. The Auto router analyzes each request and picks the best model — sending code and math to reasoning models, current-events questions to real-time models, and long documents to large-context models.

The architecture supports the GPT, Claude, Gemini, DeepSeek, Grok, Llama and Mistral families, including open-weight, self-hostable options for privacy-sensitive workloads. As new models ship, they slot into the same routing layer without changing your workflow.

AI Chat use cases

Students use it to learn concepts, build study plans, generate flashcards and check their understanding. Developers use it to generate, explain, debug and review code across a dozen languages. Writers and marketers draft, rewrite, expand and repurpose content, ad copy and social posts.

Businesses use it for plans, SWOT analyses, market research and strategy; analysts use it to interpret data and pick the right charts; and support teams use it to draft on-brand, empathetic replies. Because it remembers context and organizes conversations, it scales from a quick question to an ongoing project.

AI research assistant guide

In Research mode, the assistant breaks a question into sub-topics, presents a balanced view with arguments for and against, distinguishes facts from opinion, and flags what remains uncertain. When connected to a model with live web access, it cites sources inline and helps you judge their credibility.

Use it to summarize a field, compare options, verify claims and assemble a literature-style overview — then export the result. Always confirm critical facts against primary sources before relying on them.

AI coding assistant guide

In Coding mode, the assistant writes complete, runnable, commented code, explains how it works, debugs errors by finding the root cause, refactors for clarity and performance, reviews code by severity, and generates tests and documentation. It supports JavaScript, TypeScript, Python, Java, PHP, C#, Go, Rust, Swift, Kotlin, SQL, HTML and CSS.

For the best results, state the language, framework and versions, paste the relevant code or error, and describe the expected behavior. Code blocks render with syntax highlighting and a one-click copy button.

AI writing assistant guide

In Writing mode, the assistant drafts articles, blogs, emails, reports, proposals, social posts, product descriptions and documentation, then rewrites, expands, shortens, summarizes, humanizes or translates on request. It adapts tone and structure to your audience and purpose.

Give it your goal, audience and desired length, paste any source notes, and iterate — the conversation keeps full context, so each revision builds on the last.

Business & productivity benefits

AI Chat compresses hours of work into minutes: it turns messy notes into action items and agendas, drafts and polishes communications, produces first-draft analyses and plans, and unblocks coding and research tasks. Memory and conversation organization mean less time re-explaining context.

For teams, the architecture is ready for shared workspaces, shared prompts and a team knowledge base, plus an API for embedding the assistant into your own products and workflows.

Security & privacy overview

Privacy is the default. Conversations, memory and preferences live only in your browser, and you control them — view, edit, delete or disable memory, and delete any conversation at any time. The offline assistant never sends your data anywhere.

When a model is connected, only the necessary request is sent to the provider, processed transiently and not stored by us. Inputs are validated and rate-limited, with prompt-injection detection, XSS-safe rendering of all responses, and structured fallback handling for model outages and rate limits.

Chat API for developers

Embed the assistant in your own product. The chat API streams responses token by token, applies the right system prompt per mode, and routes to the best model. Requests are validated and rate-limited, with structured fallback handling if a model is unavailable — and the local engine needs no API key to start.
