Twin.so builds AI agents that control web browsers to automate tasks without needing an API. Their agents click buttons and fill forms just like a person would. Twin Labs (founded 2024) proved this works at scale - their Invoice Operator serves 500,000+ European SMBs through a partnership with Qonto, a fintech platform.
Important guidance for AI agent tasks
Your step-by-step instructions for the AI agent to perform work go into the Tallyfy task description. Start with short, bite-size and easy tasks that are just mundane and tedious. Do not try and ask an AI agent to do huge, complex decision-driven jobs that are goal-driven - they are prone to indeterministic behavior, hallucination, and it can get very expensive quickly.
How browser automation works with Tallyfy
Here’s a conceptual pattern where Tallyfy coordinates browser automation to pull documents from web portals.
What to notice:
Credential security - Login info is stored separately from task descriptions
Sequential execution - Each step runs in order: site access, login, then data extraction
Result delivery - Extracted data or documents go back to Tallyfy so the workflow can continue
What Twin.so offers
Twin.so provides AI agents for browser-based automation. Based on their public information:
Core capabilities:
Browser control - Agents open websites and interact with web apps
Natural language goals - Give a starting URL and a goal in plain English
Production deployment - Invoice Operator handles invoice retrieval for 500,000+ European SMBs
OpenAI collaboration - One of 15 companies chosen to alpha-test OpenAI’s Computer-Using Agent (CUA) model
Credential management - Vault system for storing website login credentials securely
Enterprise infrastructure - Browser infrastructure built for scale
Technology foundation:
Remote Chromium browser sessions
AI models including OpenAI’s CUA technology
Adapts to website changes (unlike traditional RPA scripts)
Twin Model action planning system for task processing
Twin.so says they’ve improved speed, cost, and accuracy across three generations of their technology.
Real-world deployment - Invoice Operator
Twin.so’s first major product is the Invoice Operator, built with Qonto (European fintech) and OpenAI:
Scale - Serves 500,000+ SMBs across Europe
Function - Automatically retrieves invoices from vendor portals
Support - Works with thousands of different invoice provider websites
Integration - Embedded directly in Qonto’s platform
This proves browser automation can handle production-scale, repetitive document retrieval.
Potential integration with Tallyfy
Twin.so focuses on enterprise partnerships, not self-service. Connecting with Tallyfy would likely require:
Contact Twin.so for enterprise access
Reach out through their website to discuss building specialized agents for your use case.
Define your automation use cases
Identify Tallyfy tasks that involve repetitive browser work - invoice downloads, portal checks, data extraction from web forms.
Explore API integration options
Twin.so provides an API at https://api.twin.so with endpoints for task management (start tasks, check status, retrieve results).
Set up credential management
Twin.so’s Vaults feature stores website credentials securely. Your automation tasks reference vaulted credentials rather than exposing passwords.
Work with Twin.so’s team on implementation
Custom development is needed to connect Twin.so’s browser automation with Tallyfy’s workflow orchestration.
Example automation scenario
Here’s how a Tallyfy + Twin.so integration might work for invoice retrieval:
Tallyfy task: “Retrieve monthly invoice from service provider”
AI agent products from both commercial vendors like OpenAI Operator and Claude Computer Use and open-source options like Skyvern and Manus AI can handle browser-based tasks where no API exists and should be started with small tedious tasks to avoid unpredictable behavior and escalating costs.
Skyvern is an open-source browser automation tool that uses LLMs and computer vision to execute web-based workflows through a multi-agent architecture and can integrate with Tallyfy via webhooks or middleware platforms to handle tasks like invoice management and form submissions while adapting to website changes in real-time.
Computer AI agents are programs that visually interpret and interact with any screen interface like a human would and Tallyfy provides the structured workflow layer that sends instructions and captures results so these agents can be monitored and managed alongside broader business processes.
OpenAI offers agent capabilities through the Responses API, Agents SDK and ChatGPT agent mode that connect with Tallyfy via webhooks to automate web tasks and route failures to human review.
