Cuey
Freemium
You get a confident answer from Claude, act on it, and two days later find out GPT-4 would have flagged the exact flaw you missed — because you only asked one model. Cuey exists to close that gap without forcing you to manage five browser tabs.

Summary
Cuey sits inside your existing ChatGPT, Claude, or Gemini session and routes the same prompt across multiple models so you can compare outputs before you commit to an answer. The vendor positions it at judgment-heavy tasks — research, advice, anything where a hallucination costs you time or credibility. The free tier caps comparisons at five per day, which is enough for occasional spot-checks but not for teams running systematic benchmarking at volume. Memory and prompt workflows travel with you across AI services rather than staying locked to one provider. There is no API, no self-hosted option, and no autonomous agent layer — it is a comparison tool, and the ceiling becomes visible fast when you need more than that.
Bottom line: Pick Cuey when you want a quick cross-model sanity check inside a browser session — hit the daily comparison limit on a deadline, and you are back to switching tabs manually.

Pros
- Runs the same prompt across multiple LLMs in a single workflow, so you catch a hallucination or factual gap one model misses before you act on the answer rather than after.
- Operates inside your existing ChatGPT, Claude, or Gemini session, so you avoid the context-switching cost of managing multiple browser tabs and losing your place mid-task.
- Portable memory and prompt workflows across AI services, which means the context you have built does not stay locked to one provider when you need to cross-check with another.
- Free tier available with no upfront commitment, so you can validate whether side-by-side comparison fits your workflow before committing to a paid tier.
Cons
- The free tier caps comparisons at five per day — a team running systematic prompt benchmarking or A/B testing model quality across dozens of queries hits that ceiling before mid-morning and either upgrades or routes the overflow manually.
- No API access means you cannot automate comparison into a pipeline, so any workflow that needs programmatic access to multi-model outputs — CI checks, batch evaluation, downstream analytics — requires a different tool entirely.
- Teams that need audit trails, data residency guarantees, or on-premise deployment find no self-hosted option documented anywhere in the vendor materials; at that point they move to open-source evaluation frameworks they can run in their own infrastructure.
- Comparison is one-shot with no agent or iterative reasoning layer, which means tasks requiring multi-step verification — where the output of one check should feed the next query — fall outside what Cuey can do and require building that loop separately.

One model, one blind spot
You get a confident answer from Claude, act on it, and two days later find out GPT-4 would have flagged the exact flaw you missed — because you only asked one model. Cuey exists to close that gap without forcing you to manage five browser tabs.
How it works
Cuey runs as a Chrome extension inside existing ChatGPT, Claude, or Gemini sessions. It routes the same prompt across multiple models so outputs can be compared before committing to an answer. The vendor positions the tool at judgment-heavy tasks such as research or advice where a hallucination costs time or credibility. Memory and prompt workflows move with the user across services instead of staying locked to one provider. Supported integrations include DeepSeek and Grok.
Pricing and limits
A free tier allows five comparisons per day that resets daily. The Pro plan costs $18.99 per month on a subscription basis. There is no API and no self-hosted option.
Who it is for / who should skip it
Cuey suits power users who compare multiple LLMs daily, want portable memory across chats, and need side-by-side analysis to reduce hallucination risk. Teams running systematic benchmarking or A/B testing hit the free-tier cap quickly and must upgrade or handle overflow manually. Anyone needing API access for pipelines, batch evaluation, or audit trails should skip it entirely.
