Every AI capability, one workspace
Claude has Artifacts. ChatGPT has Voice. Perplexity has Research. Kova has all of it — plus every model, plus BYOK, plus MCP, plus Projects.
Artifacts & Canvas
Split-pane live editing for code, markdown, HTML, React components, SVG, and Mermaid diagrams. Watch the model build and edit in real time.
Agent mode with tools
Kova calls the web, fetches pages, runs Python/Node in a sandbox, generates images, and searches your docs — autonomously, mid-conversation.
Deep Research
Multi-step agentic research: plan, search (Exa/Tavily), read, synthesize. A full report with numbered citations in a couple of minutes.
Projects with RAG
Upload PDFs, DOCX, markdown. Chunked, embedded, and pgvector-searched. Each project has its own system prompt, docs, and context.
Realtime Voice Mode
OpenAI Realtime via WebRTC. Speak naturally, hear responses immediately, with a live transcript.
Reasoning visualization
See the model's thought process — Claude extended thinking, o1/o3-mini reasoning, Gemini thinking. Collapsible, live-streamed.
Image generation
Flux 1.1 Pro, DALL-E 3, Imagen 3 — the model generates images as a tool call, uploads them to your storage, attaches them to the chat.
MCP connections
Hook up Notion, GitHub, Linear, Slack, Zapier — any MCP server. Tools discovered automatically and offered to the agent.
Compared to the rest
The things you actually use AI for — in one place.

See what builders and researchers are saying about Kova.
"Compare Mode has completely changed how I evaluate model outputs. Instead of context-switching between tabs, I can see GPT-4o and Claude side-by-side instantly. Saves me hours every week."
"I was skeptical about sharing my API keys anywhere, but Kova's AES-256-GCM encryption and zero data-sharing policy convinced me. It's the only place I trust with my keys."
"Having access to GPT-5.1, Claude Opus, and Gemini from one workspace is a game-changer. No more juggling subscriptions or browser tabs. Kova just works."
