Le Chat deep research: sources, findings, and follow-up

For Le Chat deep research, start with a defined question and a checked source collection, then verify the important claims before using the findings. Le Chat is now Vibe↗ (opens in a new tab); the current guides document Libraries and Projects, but do not establish a dedicated Deep Research control. The workflow below uses those documented source tools. Save the verified outcome in fenbs so another AI can pick up the next step.

How do you start a focused research task?

Write the question before collecting documents. “Research sustainable packaging” is too broad to check efficiently. A better example is: “Which of these three packaging materials meets the requirements in our approved specification, and what evidence is missing?” The question tells you which sources belong and what a useful answer should contain.

1. Name the decision or deliverable the research will support.
2. Write one question and the boundaries of the search.
3. Gather the original documents and source URLs you are allowed to use.
4. Choose the output: a short findings table, a comparison, or a list of open questions.
5. Decide which claims need a person to check before the result can be used.

Set a stopping point. You might stop when each requirement has a supporting passage or an explicit evidence gap. Without that boundary, it is easy to keep asking for broader summaries while the original question remains unanswered. More paragraphs do not necessarily move the decision forward.

Where do you put the source material?

Mistral’s Libraries guide↗ (opens in a new tab) documents persistent collections of documents and indexed webpages. Open Libraries → New Library, then drag in documents or click Upload. For webpages, choose Webpage, enter the URLs, and click Index. Attach the collection in a chat through + → Libraries.

Keep the collection tied to the question. A public supplier specification may support a material claim; a presentation about the supplier’s ambitions may not. Include versions in your own filenames and keep a short source list so you can distinguish an updated specification from a superseded draft.

Webpage indexing includes text, not child pages, images, or charts. If an answer depends on a chart or a linked report, do not assume indexing the parent page supplied that evidence. The separate Le Chat Libraries guide covers organizing the collection and access controls.

What should you ask the assistant to produce?

Ask for a structure you can audit. A polished essay can hide uncertainty; a small claim-and-evidence table makes the checking work visible. State that missing evidence should remain missing, and ask for opposing findings as well as support for your preferred answer.

• The question: restate the exact problem being answered.
• The claim: one factual statement at a time.
• The evidence: the source name and the passage that supports the statement.
• The limit: exceptions, dates, or conditions that narrow the claim.
• The next check: what is still needed before a person can act.

For example, ask: “Use only the attached sources. For each material, identify the supported requirements and quote only the short passage needed to check them. Separate direct evidence, your interpretation, and unanswered questions. Do not choose a winner where a required measurement is missing.”

For help making instructions explicit, see Mistral system prompts. The aim here is not a special phrase that guarantees accuracy. It is an output that makes a wrong or unsupported conclusion easier for you to detect.

How do you verify the important findings?

1. Choose the claims that would change the decision if they were wrong.
2. Open the original source and locate the supporting passage yourself.
3. Read nearby qualifications, tables, and definitions.
4. Check whether the document applies to the exact product, place, and version in your question.
5. Mark the claim as checked, contradicted, or still unresolved. Revise the conclusion when the evidence changes.

Look for a specific failure: a source may mention a general material family while your question concerns a particular grade. An answer that drops that distinction can sound reasonable and still be unusable. Ask the assistant to show which part of the statement is directly supported and which part is an inference.

Keep a short record of the checks in fenbs’s shared work record. “Checked against specification revision C; measurement still missing” tells the next assistant more than “research complete.” It also prevents an open question from becoming a fact merely because it appeared in a fluent summary.

What should you do when the evidence conflicts?

Do not settle a contradiction by asking the model to sound more certain. Put the competing claims next to each other and compare their scope, dates, and source owners. Two documents can both be accurate while describing different circumstances.

Write down who can resolve the gap. A missing product measurement may need a supplier response; an unclear internal requirement may need a person on your team. Give that question an owner and a next action. Research should make the uncertainty easier to act on, even when it cannot remove it.

If you expect several related chats, Mistral Projects↗ (opens in a new tab) group conversations, instructions, and shared files. Use that organization to keep the source task clear. For the separate question of choosing an assistant, see Claude versus Mistral.

What should you keep after the research?

Keep the answer to the original question, the sources that support it, the remaining limits, and the next action. Preserve the difference between a verified finding and a person’s decision based on that finding. A useful handoff should make sense without reading the whole conversation.

Add a reason to revisit the finding when appropriate: a new source version, a missing test result, or a changed requirement. If you later need a broader account copy, use the separate Le Chat export guide. An archive and a checked research conclusion serve different purposes.

How to keep research findings with fenbs

Keep your checked findings so you can carry on from exactly where you left off, on any device and in any other connected AI. Save the useful result while the evidence is still fresh.

1. Create a free account.
2. Write the question, the checked answer, and the source that supports it. Keep unresolved claims clearly marked.
3. Connect Le Chat to fenbs using the current Vibe Work connector controls. See Integrations for guidance; a custom connector must be added by an administrator.
4. Save what still needs checking and where to start next. Ask the next connected assistant to read that before doing more research.

fenbs does not verify sources for you or provide a dedicated research engine. If the task ends with a single checked answer, a short local record may be enough. It helps when the findings need to guide later work across people or AI apps. Find more workflows in AI at work.
