Three steps. Any workflow.
Drag cards onto the canvas
Pick from generation, data, chat, agent, and analysis cards. Each card is a building block.
Connect them into a workflow
Draw connections between cards to define data flow. Branch, merge, loop — build logic visually.
Run — or save as a reusable app
Hit run and watch your workflow execute in real time. Save it as a reusable app for different inputs.
Everything you need, in five card types
Every card is a node on the canvas. Connect them in any combination to build workflows for any task.
Generation
Create text, images, video, and audio with any model. Mix and match to get exactly the output you need.
Text · Image · Video · Audio · Music
Data Storage
Load, save, transform, and organize your data. The backbone of any workflow.
Files · JSON · CSV · PDF · Database · Variables
Chat
Conversations with thinking, reasoning, and memory. Chain-of-thought for complex problem-solving.
Conversation · System prompts · Thinking · Memory
Agent
Autonomous tools that search, browse, and act. Multi-step tasks completed independently.
Web search · Crawl · Code execution · Tool use
Analysis
Extract, classify, and understand content. Turn raw data into usable information.
OCR · Speech recognition · Classification · Extraction
Every format your workflow needs
See it in action
The canvas is where it all comes together. Drag cards, draw connections, see your data flow in real time.
Built different
"AI tools charge $50+ a month."
Pexper is free. Bring your own API keys and pay providers directly — no markup. Or use local models for $0.
"I'm locked into one provider."
Pexper works with every provider. Switch from OpenAI to Claude to a local model in one click. No migration, no lock-in.
"I don't trust the cloud with my data."
Run models entirely on your hardware. Your prompts, your files, your outputs — nothing leaves your machine.
"I'm not a developer."
You don't need to be. Connect your existing ChatGPT or Claude subscription directly — no API keys, no terminal commands, no setup.
"I need text AND images AND video AND audio."
One canvas. Every format. Every model. Build workflows that mix text, images, audio, video, web search, and data analysis in a single flow.
