Agents

Every answer traces back to the source

Ask a question and the agent answers from your own documents, with a citation to the exact file, page, and passage behind every line. Click any source to read the original. No black box, no invented facts.

Workflows

Run the same process the same way, every time

Build a multi-step task once from typed building blocks, then run it on demand or on a schedule. Review gates pause for human sign-off where judgement is needed. Every step is logged.

Agents handle the work that needs reasoning. Workflows handle the work that has to be identical run after run.

Integrations

Connected to your systems, bound by your permissions

Agents reach into SharePoint, iManage, Outlook, Power BI, Slack, and thousands more through the Model Context Protocol. They sign in as each user, so they only ever see what that person can already see. No privilege escalation, existing boundaries respected.

Schedule a daily briefing or delegate work intelligently to minimise admin overhead.

Frequently asked questions

What types of documents can it process? +
PDFs, Word documents, Excel spreadsheets, emails, and plain text. The platform extracts structured data, searches across documents using vector search, cross-references figures between sources, and generates new documents from the results.
How is this different from ChatGPT or Copilot? +
ChatGPT and Copilot are conversational wrappers. CompleteFlow combines AI agents with deterministic workflows and document processing. Choose managed cloud, private cloud, or on-premises deployment. Uses per-user credentials when accessing your systems, with full audit trails on every action.
Can we choose which AI model to use? +
Yes. CompleteFlow works with any state-of-the-art model: Anthropic Claude, OpenAI, Google Gemini, Azure OpenAI, and open-weight models. You can assign different models per workflow: a fast model for extraction, a powerful model for reasoning. Swap providers without changing any workflow logic.
How is this different from Harvey, Legora, or CoCounsel? +
Three structural differences. First, deployment: those platforms are multi-tenant SaaS where every customer shares infrastructure. CompleteFlow is single-tenant in your own cloud. Second, model: they pick one model and lock you to it. CompleteFlow runs any model you choose and lets you switch any time. Third, pricing: per-seat SaaS bundles token markups into the seat price. CompleteFlow charges for the platform; you pay your model provider directly at their published rates.
Do you mark up the LLM costs? +
No. You connect your own Anthropic, OpenAI, Azure OpenAI, or Google Cloud account, and the tokens are billed directly by the provider at their published rates. Our platform fee is separate and predictable. We have no incentive to throttle how much your team uses the AI.
Where does our data go? +
You choose: our managed cloud, your own cloud tenancy (Azure, AWS, GCP), or on-premises. In all cases, LLM calls go through private endpoints, your data is never used for model training, and you control the encryption keys.
How quickly can we get started? +
Six weeks from kickoff to first production workflows. This includes platform deployment, integration with your systems, workflow configuration, and team training.
Do we need AI expertise in-house? +
No. We handle the platform setup and initial workflow configuration. Your team uses the visual builder and conversational agent day-to-day. No ML engineering required.
Can your team build custom solutions for us? +
Yes. Our professional services team builds custom document automation solutions, develops new platform features, and tailors CompleteFlow to your organisation's specific workflows, systems, and integrations. From bespoke connectors to entirely new agent behaviours, we scope it as part of the engagement.
