How to improve claim fact-check lists
Cut noise from claim fact-check lists by removing extra adjectives while preserving SOURCE facts in Brave Leo.
Raise quality by insisting on a single success check before debating style.
Make review easier by labeling fields that must never change.
Speed iteration by cloning the last good run and altering only one control.
Stabilize outputs by pinning settings after the pilot is approved.
Reduce rework by rejecting drafts that invent claims.
Improve handoffs by recording which control produced the best result.
Harden the workflow by testing an incomplete input before trusting defaults.
Prompting and usage guidance
Name the claim fact-check lists job, audience, and success check before opening Brave Leo.
Paste only verified facts under SOURCE so Brave Leo cannot invent details.
Specify the deliverable shape up front.
Call out fixed details versus flexible style choices.
Ask Brave Leo to flag unsupported claims before you accept the draft.
Limitations to respect
Check Brave Leo plan gates for claim fact-check lists on brave.com/leo before you promise timelines.
Keep drafts unpublished until a human confirms SOURCE facts.
Brave Leo can be wrong. Treat claim fact-check lists as provisional until review.
If documentation is silent on a claim, leave it out rather than guessing.
Practical tips for this workflow
Pilot once before batching claim fact-check lists in Brave Leo.
Keep a reusable template with variables for claim fact-check lists.
Separate creative instructions from SOURCE facts.
Log settings from the best run.
Common mistakes
- Skipping the pilot run before scaling volume
- Inventing pricing, quotas, or features not on official pages
- Mixing unrelated workflows in one session
- Publishing without a human review gate
Treat claim fact-check lists in Brave Leo as a production workflow: brief, pilot, refine, then ship with review. Related reading: /blog/how-to-use-brave-leo-for-writing-help-on-page-context, /blog/how-to-use-brave-leo-for-privacy-aware-q-and-a, /blog/how-to-use-brave-leo-for-model-choice-for-tasks.
