OneOff is the no-subscription tier. Try the home-page demo for free with no signup, or sign up and pay per review — $9 for a quick review, $19 for a deep review (all 4 AI models). No monthly fee. Upgrade to Pro for unlimited reviews if you run more than 5 deep reviews per month.

No subscription. Pay $9 for a quick review or $19 for a deep review, only when you run one. Each upload prompts you to choose quick or deep, then charges that one-time amount via Stripe before the review starts. If you run 6+ deep reviews per month (6 × $19 = $114 > $99), Pro at $99/mo with unlimited usage is cheaper.

Power users get more value (and lower latency) by routing reviews through their own LLM provider accounts. You bring keys for Claude, GPT-4o, Gemini, and Grok; we encrypt them with Google Cloud KMS, never store them in plaintext, and route every review through your keys. We don't see your usage on your accounts; you keep full control of provider billing.

Fact Check fans your document out to GPT-4o, Gemini, and Grok in parallel. A claim is only flagged when at least 2 models agree AND at least one of them produces a source URL — without those gates the false-positive rate is too high to trust. Available on every paid plan.

All four — Claude (Anthropic), GPT-4o (OpenAI), Gemini (Google), Grok (xAI). On OneOff, every review uses our keys (we cover provider costs). On Pro and Organization, every review uses your own keys (BYOK).

Each time you upload a document and get feedback from your selected personas, that's one review. Selecting more personas doesn't use additional reviews — you get the full panel every time. Fact Check runs count the same as a review.

Yes. Documents are encrypted in transit and at rest. We never use your uploads to train AI models. Documents are automatically deleted after 30 days unless you choose to keep them.

Pro and Organization subscriptions are month-to-month with no contracts. Cancel anytime from your account settings and you'll keep access through the end of your billing period. OneOff is per-review — there's nothing to cancel.

PDF, Word (.docx), PowerPoint (.pptx), plain text, Markdown, and HTML. We extract the text content and pass it to your selected reviewers for analysis.

Pro lets you create 1 custom reviewer persona tailored to your domain — for example, one that knows your brand guidelines, your codebase architecture, or your regulatory requirements. Organization lets you create unlimited custom personas with custom knowledge bases.
