Teams step away from reOS for a few concrete reasons. There is no free plan, so the entry price is $59 per month. Interview units are capped (12, 60 or 300 a month) and sessions over 90 minutes consume extra ones. SSO needs Scale at $999 per month, and Enterprise pricing is custom, so large costs are unknown up front.
The four alternatives in our catalog are general AI assistants rather than research platforms, so none of them runs recruiting or panels. Gemini Notebook (formerly NotebookLM) answers questions and builds summaries, audio and slides grounded in your own sources; it has a free tier, price not stated. ChatGPT has a free tier and Plus is $20 per month per user, with usage limits. Claude has a free tier and Pro is $20 per month, or $17 per month on annual billing. Perplexity searches the web with cited sources; it has a free tier and its Education Pro is $10 per month for verified students and faculty.
"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 reOS profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| reOS (this page) | $59/mo (Researcher) | No | Web | There is no free plan, and each plan caps research units per month (12 on Researcher, 60 on Team, 300 on Scale). |
| 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. |
| 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. |
| 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'. |

Yes. Gemini Notebook, ChatGPT, Claude and Perplexity all have a free tier in our catalog, whereas reOS shows no free plan.
Documented reasons are the missing free plan, monthly unit caps, extra units for long sessions, and SSO being limited to Scale and above.
Gemini Notebook is described as answering questions and creating summaries grounded in your own sources. Its starting price is not stated.
ChatGPT Plus costs $20 a month for each user. Claude Pro is $20 per month, or $17 per month with an annual subscription of $200 billed up front.
