From text to counterargument
Strength score
A single score from 0 to 100, built from strong points, weak points, and detected logical fallacies.
Logical fallacy detection
Precisely marks which passage contains the error and names the type: no vague judgement.
Check your own text
Analyse what you’re about to say before you send it: score, logical fallacies, and the counterarguments you can expect.
Improve your text with AI
Rewrite your own text while preserving your tone and message.
Response in your tone
Choose from seven tones (professional, assertive, de-escalating, clear, witty, informal, or legal) and receive a ready-to-use reply.
Any input, from any app
Share text or a link directly from any app to Rhetoriq, or select text somewhere and tap Rhetoriq in the menu. Pasting, voice input, or scanning a photo also works.
Quiz & Refute
Train with the Fallacy Quiz and Refute: spot logical fallacies against the clock or choose the strongest refutation for a weak argument.
14 languages
The app works in 14 languages and analyses virtually any language you input.
Three steps. A few seconds.
Input
Text, link, voice, or photo: whatever you encounter in a conversation or timeline.
Read the analysis
Strong points underlined, logical fallacies flagged, one score that weighs the whole.
Respond sharply
Choose a tone and send a response that holds up: well-reasoned, not impulsive.
Anyone who wants to respond with solid reasoning
Meetings & negotiations
Assess a proposal for weak points and enter the room with a well-reasoned counterargument.
Social media
Spot the logical fallacy immediately and respond wittily without getting dragged into a pointless back-and-forth.

Frequently asked questions
Which actions cost credits?
Every AI action costs 1 credit: an analysis, a generated response, a quiz or practice session, text recognition from a photo, text rephrasing, audio transcription, or improving your own text.
Do my credits expire?
No. Purchased credits never expire; you keep them as long as you use the app.
Is my data stored or used to train AI?
No, we don’t save anything on our server unless you enable history synchronisation yourself. Input text, audio, and images are only sent to AI services to process your request, never to train AI models. If you enable history synchronisation (Settings → Account), we do store your analyses, linked to your account, so you can view them on your other devices. You can disable this at any time. See our privacy policy for details.
In which languages does the app work?
The interface is available in 14 languages: Dutch, English (UK and US), Danish, German, Finnish, French, Spanish, Italian, Norwegian, Swedish, Polish, and Portuguese (European and Brazilian). The app analyses content in virtually any language you input, regardless of the interface language.
Do I pay a subscription?
No. You purchase credits once and use them at your own pace. There’s never any automatic billing.
Is there an iOS version?
Not yet: Rhetoriq is currently only available for Android.
How reliable is the AI analysis?
Rhetoriq doesn’t run on a generic chatbot prompt but on a specifically developed and tested system that recognises a fixed list of 16 logical fallacies and 6 manipulation techniques, with clear rules for citation and reasoning. We continue to refine this based on real analyses. However, no AI is infallible. Use your own judgement when assessing the results.
Does the app work offline?
No, an internet connection is required for analyses and responses, as they are processed by AI services on our server. You can view your saved history offline.
