Apodex asks you to sign in before you can ask a question, so you cannot try it first. Credit costs are dynamic rather than fixed per request, which makes it hard to budget per report. There is no public price list on the pricing page, with plans visible only after sign-in, and Premium resets credits each month.
Perplexity is an answer engine that searches the web and replies with cited sources; the listed plan is Education Pro at $10 per month for verified students and faculty, and a free plan exists. ChatGPT Plus is $20 per month, with a free plan, for general research and writing. Claude Pro is $20 per month, or $17 per month on an annual subscription, with a free plan. Gemini Notebook answers from your own sources, free to use, with no price in our pack. Perplexity is the closest to cited research.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.
Taken from the documented limitations in our Apodex profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Apodex (this page) | $50/mo (Premium) | Yes | Web, API | Die Credit-Kosten pro Frage sind dynamisch, daher lassen sich die Ausgaben pro Bericht anhand der Preisseite nicht vorhersagen. |
| Perplexity | $10/mo (Education Pro (consumer, verified students/faculty)) | Yes | Web, API | The consumer pricing page is blocked to automated checks, so the Pro price could not be confirmed here, and free-tier Pro Search and Research access are described only as 'very limited' / 'limited'. |
| ChatGPT | $20/mo (Plus (consumer)) | Yes | Web, Desktop, Mobile, API | Fast jedes Tool (Uploads, Bilder, Sprache, Deep Research, Codex) hat tarifabhängige Nutzungsgrenzen, die sich laut OpenAI im Laufe der Zeit ändern können, und die API wird getrennt von jedem ChatGPT-Abo abgerechnet. |
| Claude | $20/mo (Pro) | Yes | Web, Desktop, Mobile, API | Alle Tarife haben Nutzungslimits, die sich nach einem Zeitplan zurücksetzen; das bezahlte Chat-Abonnement enthält keinen API-Zugang, der separat pro Token abgerechnet wird. |
| Gemini Notebook (formerly NotebookLM) | Not published | Yes | Web, Mobile | Free tier has standard usage limits and 50 sources per notebook; higher limits need a Google AI Plus, Pro or Ultra plan, which Google says are only available in specific regions. |
