What T661 software actually does
T661 software is specifically designed for CRA's project narrative requirements. It guides you through each section of Form T661 Part 2 — the project description — and produces structured narratives that align with how CRA reviewers evaluate claims.
The T661 form asks for: what technological uncertainties were addressed, what work was performed to overcome them, what advancements were achieved, and what knowledge was gained. Good T661 software turns your project description into answers that map directly to these criteria.
From raw description to T661-aligned narrative
Most founders start with a rough description of what they built. T661 software structures that into CRA's preferred format: specific technical uncertainty, systematic investigation approach, measurable advancement, and retained knowledge.
Raw: 'We built a real-time dashboard for our IoT devices.' T661-aligned: 'We faced uncertainty about whether our edge-compute nodes could process and aggregate sensor streams at sub-second latency without dropping events. We investigated three approaches — batch aggregation, streaming with windowing, and event-driven micro-batching — and found that a hybrid approach achieved our latency target while maintaining data completeness. This knowledge informed our platform architecture for subsequent device integrations.'
