Parafact AI
Paste human or AI-written text and get each claim labeled Accurate, Inaccurate, or Subjective with a citation in seconds.
Parafact AI is worth paying for when verification speed is the bottleneck in a publishing or moderation pipeline. The combination of a paste-and-check web flow with per-claim citations and a documented REST endpoint (POST api.parafactai.com/v1/factcheck returning claim, label, source, justification) covers both manual editors and engineers, which most single-purpose checkers do not. For a working journalist or content marketer checking drafts daily, a paid tier is a reasonable step up from the free entry point. The catch is scope: the vendor documents English-only support, names no underlying models, publishes no accuracy benchmark, and the scrape shows no batch document upload, so treat

Skip Parafact AI if your writing is not in English, if you need to fact-check a folder of documents in one batch rather than paste text or call the API, or if you need a published accuracy benchmark before you trust automated labels.
The Free tier's 100 checks per month is a hard ceiling, and an active writer checking full drafts can burn through it quickly — then you are looking at the paid tiers.
The free entry point of 100 checks per month suits an occasional writer validating a few drafts; Pro at $19/mo fits a working journalist, researcher, or marketer running daily checks; Enterprise is custom-priced with unlimited checking, a dedicated account manager, custom integrations, and an SLA for high-volume moderation. Against cheaper single-model prompt wrappers Parafact is pricier, but it bundles citations and a structured API that most cheap checkers do not offer.
In short

Best for Editorial teams and journalists publishing on deadline, Researchers and graduate students checking written work, Legal professionals verifying dense documents.

What is Parafact AI?
Parafact AI — Paste human or AI-written text and get each claim labeled Accurate, Inaccurate, or Subjective with a citation in seconds. Best for Editorial teams and journalists publishing on deadline, Researchers and graduate students checking written work, Legal professionals verifying dense documents. Free to start; paid plans from $19/mo.
Parafact AI is a paste-and-check fact-checking tool for human-written and AI-written text. You drop a draft into the browser app and it breaks the text into individual claims, then returns three things per claim: a label (Accurate, Inaccurate, or Subjective), a source link, and a plain-language justification. It is aimed at people whose credibility is on the line — editorial directors verifying publications, researchers and graduate students checking theses and reports, lawyers and paralegals cross-referencing dense documents, marketers checking AI-drafted copy, and engineers wiring fact-checking into a product. The developer side is a documented REST endpoint at api.parafactai.com/v1/factcheck: POST with a bearer token and a JSON body containing your text, and you get back a structured array of claim, label, source, and justification objects. That structured output is why teams use it for automated content moderation at scale rather than only for one-off checks. Parafact states it is trusted by 12,500+ professionals. The vendor describes its checking as fully automated with no manual review step, and says it uses state-of-the-art AI models without naming which models. Support is English-only.

- Bearer-token API authentication

- Use for automated content moderation at scale
- Coverage for journalism, research, legal, marketing, corporate comms, and social media text

Our long-form take written Jul 15, 2026 is more than 90 days old, so it is being re-reviewed against current data and is not shown.
Limitations
- The vendor states it uses state-of-the-art AI models but names none of them, and no accuracy benchmark is published, so treat each verdict as a fast first pass rather than a final ruling.
- Support is English-only, which rules out multilingual editorial and international compliance work.
- The scraped evidence documents the paste-and-check web workflow and the API endpoint, but no batch processing capability is described, so teams with large document sets should not assume they can drop a folder in and get results.
- The 'Subjective' label means some claims come back neither confirmed nor refuted — useful for honesty, but it means Parafact will not clear every line.
- The pricing/plans page did not yield usable content in this scrape, so cost limits and per-tier credit allowances cannot be verified from the evidence here.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Parafact AI actually fits — and what changes day-one when you adopt it.
You finish editing a feature and paste the full draft into the Parafact web app before the piece goes live.
Outcome: Each factual claim comes back labeled Accurate, Inaccurate, or Subjective with a source link and a justification, so you fix or cut the flagged lines in minutes instead of assigning a research pass.
You generate campaign copy with an AI writer, then run it through Parafact before sending the draft to the client for approval.
Outcome: Claims the AI invented get flagged as Inaccurate with a citation, letting you correct the copy before the client ever sees it and protecting the credibility of the campaign.
You POST user-submitted text to api.parafactai.com/v1/factcheck with a bearer token and parse the JSON response in your review pipeline.
Outcome: You get back an array of claim, label, source, and justification objects you can surface in your moderation queue, replacing manual reviewer reads of every submission.

Setup time & first value

For a writer or editor, first value is essentially immediate: open the browser app, paste text, and you have labeled claims with citations in seconds — no install and no configuration. For a developer, budget time for the API access request and token provisioning described on the site, then a short integration pass to consume the JSON response and map claim, label, source, and justification into
Switching to or from Parafact AI
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual editorial research passes: paste the draft into Parafact first to generate a cited claim list, then let editors check only the flagged lines.
- →From a chat-assistant prompt such as 'fact-check this': move to Parafact's structured claim, label, source, justification output instead of an unstructured chat reply.
- →From in-house scripting against a general LLM API: replace the freeform prompt with the POST api.parafactai.com/v1/factcheck endpoint to get citations attached to every label.
- ↗To a multilingual fact-checking or research platform: re-run your corpus there if your operation expands beyond English-language material.
- ↗To a document-level verification suite: switch to a tool that ingests batches or folders if you need bulk processing rather than paste-and-check or per-call API requests.
- ↗To an in-house LLM pipeline with your own retrieval sources: relevant if you need a published accuracy benchmark or full control over which models evaluate your claims.
