Deep Research

Deep Research turns a question into a structured, cited report. It's a dedicated workspace mode – switch to it with the telescope icon in the left rail.

Start a run

The Research home is a single centred input. You choose:

• Source – Research my files, Research the web, or Files + web.
• Template – Exploration brief, Formal report, Free-form, or Literature review.
• Depth – standard or deep.

For a files or hybrid run, Fosnie may show a short plan gate first: up to three tappable clarifying questions, a one-line scope summary, and a rough time estimate, so you can narrow scope before it spends time. Its scope is everything you can already access – the Projects and knowledge bases your permissions allow, resolved conservatively.

What happens

The run executes in the background and shows its phases – plan → collect → notes → outline → write → check → deliver.

• Files runs a census: it reads every in-scope document once, caches per-document notes, and reuses them across runs. Above the census cap (500 documents by default) it samples, and it always includes a coverage appendix stating honestly what was reviewed. Citations look like [D1], and this path performs zero egress – it works air-gapped.
• Web runs an agentic search loop per sub-question. Citations look like [W1].
• Hybrid does the corpus first, then targeted web rounds, keeping the two visibly separate – a [D#] reference section for your documents and a [W#] section for the web, plus a consensus / contradictions / gaps summary.

The report

The report posts as a normal message – title, sections, dual reference lists, and a coverage note – with inline citations. Fosnie always saves it as a Markdown artefact; the message carries Save as DOCX and Save as PDF buttons, and a Create page button that turns it into a self-contained HTML page.

You can Stop a run mid-flight, or Refine it – reopen the home prefilled with the same parameters for a fresh pass.
