Checking facts while I type saves me hours of Google searches.
Incredible writing assistant with live verification.
Free trial period needs to be longer.
Game changer for content writers.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Factful verifies factual statements against live web sources, filtering the material it finds for credibility rather than simply matching wording.
Proofreading runs alongside fact-checking so you fix surface errors and substantive inaccuracies in one workflow instead of switching tools.
Monitor corrections, track how your accuracy evolves over time and spot the errors that recur across subjects.
A command system the product brands the 'Everything Key' lets you trigger writing and formatting actions without leaving the line you are editing.
Factful is positioned to check writing across a large number of languages, making it usable for multilingual drafting.
Most editors stop at grammar. Factful's premise is that correctness and accuracy belong in the same pass: it checks spelling and grammar while also verifying factual statements against live web sources. The product describes scraping the web in real time and then scanning and filtering that material to surface only the most credible sources, which is what makes a factual claim verifiable rather than merely plausible.
When it flags something, Factful does not just underline it — the analytics view lets you monitor corrections, see how your accuracy evolves across subjects, and identify which errors you make most often. That feedback loop suits writers who care about improving over time, not just shipping a clean draft. An in-line slash command system, which the product calls the 'New Everything Key', puts formatting and writing actions a few keystrokes away so you stay in the flow of composition.
Factful is delivered as a writing environment with a Chrome extension presence, and the site lists support for a very wide range of languages. At the time of review the product was advertising full access at no cost under a 'free for a limited time' banner, with a regular price of about $9.99 per month; features listed across the two tiers include advanced fact-checking, analytics, slash commands, advanced proofreading, model fine-tuning and faster processing. Because limited-time offers change, treat any specific price as subject to change and confirm on the site.
Check factual claims against live sources before publishing so posts do not carry unverified figures or easily disproved assertions.
Combine proofreading and fact-checking in one pass to catch both typos and claims that do not hold up against credible sources.
Improve spelling and grammar across a long draft while also verifying that the facts you state remain correct after edits.
Use real-time analytics to see which error types recur, then target those in briefs and templates to cut down on rework.
