Chain AI tools together. Automate multi-step processes with AI.
Chain AI Tools Into Automated Pipelines
Workflows let you connect multiple AI tools together. The output of one step becomes the input of the next. Automate multi-step processes that would take hours to do manually.

How to Build a Workflow
- Start with a tool — Pick any AI tool as your starting point (Chat, Image, TTS, etc.).
- Copy the output — Use the result as input for the next tool. For example, take AI-generated text and feed it into text-to-speech.
- Automate with the API — Chain API calls together in a script for fully automated pipelines. See our API docs.
- Use Zapier — Connect Free.ai to 5,000+ apps for no-code automation. See our Zapier integration.
API Workflow Example
Chain two API calls — generate text then convert to speech:
import requests
API_KEY = "YOUR_API_KEY"
HEADERS = {"Authorization": f"Bearer {API_KEY}", "Content-Type": "application/json"}
# Step 1: Generate text
resp = requests.post("https://api.free.ai/v1/chat/completions", headers=HEADERS,
json={"model": "qwen2.5-72b", "messages": [{"role": "user", "content": "Write a 2-sentence product description for wireless earbuds"}]})
text = resp.json()["choices"][0]["message"]["content"]
# Step 2: Convert to speech
resp = requests.post("https://api.free.ai/v1/tts", headers=HEADERS,
json={"text": text, "voice": "af_heart"})
with open("output.mp3", "wb") as f:
f.write(resp.content)Available Tools to Chain
- AI Chat (346+ models)
- AI Coder
- Image Generation
- Video Generation
- Text to Speech
- Speech to Text
- Translation (450+ langs)
- Music Generation
FAQ
Workflows let you chain multiple AI tools together so the output of one step becomes the input of the next. For example, generate text with AI Chat, create an image from that text, convert it to speech, and translate it -- all in an automated pipeline.
For simple workflows, you can manually copy output from one tool to the next using the web interface. For fully automated no-code workflows, use our Zapier integration to chain Free.ai tools with 5,000+ other apps.
A typical blog pipeline: AI Chat writes an article from a topic, Image Generation creates a featured image, Text-to-Speech generates an audio version, and Translation localizes the content to multiple languages.
Chain API calls in a script. Call one endpoint, extract the response, and pass it as input to the next endpoint. The Python example on this page shows generating text and then converting it to speech in two API calls.
Any combination of the 200+ tools: AI Chat, AI Coder, Image Generation, Video Generation, Text-to-Speech, Speech-to-Text, Translation, Music Generation, Image Upscaling, Background Removal, OCR, Summarization, and more.
Each step in a workflow uses tokens according to that tool's cost. If you chain four tools, you pay the token cost of each one. Self-hosted models are free within your daily limit, making them the most cost-effective for multi-step workflows.
Yes. Zapier lets you connect Free.ai API calls with triggers from 5,000+ apps. Set up multi-step Zaps that automatically run AI tasks when events occur in Gmail, Slack, Google Sheets, and more.
Transcribe a voicemail with Speech-to-Text, use AI Chat to classify the issue and draft a reply, Translate the reply to match the customer's language, then convert it to speech with Text-to-Speech for an automated voice response.
Yes. Use cron jobs (for API scripts), Zapier scheduled triggers, or any task scheduler to run workflows on a recurring basis. For example, generate a daily AI news summary every morning.
There is no limit on the number of steps. You can chain as many tools as needed. Each step is an independent API call, so workflows can be as simple or complex as your use case requires.
Save your API scripts or Zapier configurations as templates to reuse. We plan to add a workflow builder interface in the future that will let you visually create, save, and share workflow templates.
Any language that can make HTTP requests works -- Python, JavaScript, Go, Ruby, PHP, Bash, and more. Our API documentation includes examples in Python, JavaScript, and cURL to get you started.
