Chain AI blocks into flows that run
Link models, prompts, web search, your files and social accounts block by block. Run a chain from the app, on a schedule or over the API, and pay only for what runs.
Start chainingHow a chain runs
Every block does one thing. Chains pass the result of one block to the next.
- 1
Pick your blocks
Models from the whole OpenRouter catalogue, prompts, web search, files, Instagram, inputs and outputs. Or start from a ready-made project.
- 2
Link them
Drag blocks onto the canvas and draw the links between their ports. Test any block on its own, then the whole chain.
- 3
Run it anywhere
In the playground, on a schedule, or with one HTTP call. Each model call costs credits at the model's price plus our fee, shown before you buy.
What you can chain today
Every block runs on a Tadata service: flows on flowz, models on zai, social on sozial, billing on the wallet.
Visual chains
A canvas to build flows from blocks: models, prompts, agents, tools, inputs and outputs.
Chat & playground
Talk to any model, try prompts and compare answers before you put them in a chain.
Model catalogue
Filter and sort the models by provider, context size, modality and price per token.
Scheduled runs
Run a chain every hour, day or week and find each run's result in the history.
Files
Upload documents and images and use them as inputs in your chains.
Web search
Search the web with Exa and feed fresh results to your models.
Connect an Instagram account, publish generated posts and follow their numbers.
API
Run any of your chains with one HTTP call: POST /api/run/{flow_id}.
One canvas for models, tools and data. Each line below is a chain you can build today.

How credits work
A call costs the model's own price plus OpenRouter's fee and our platform fee, VAT included, rounded up to the next credit. The minimum is 1 credit per call. Building and editing chains is free.
