Overview
Thinkbeside is a Chrome browser extension that aggregates GPT, Claude and Gemini LLM interfaces into a single sidebar panel, eliminating the need to open separate browser tabs or websites for each service. Launched as a Show HN submission in October 2026, it functions as a lightweight multi-LLM router rather than a standalone model or agent. The extension sits dormant until activated, displaying a collapsible sidebar where users can prompt different models in parallel or sequentially without leaving their current browsing context. No pricing information or monetisation model has been published; the tool appears to operate as a free browser utility at present. Under the hood, Thinkbeside acts as a passthrough to existing APIs—it does not train or host its own LLM, but rather orchestrates calls to OpenAI, Anthropic and Google's published endpoints. This approach means users incur standard API costs (if authenticated) or rely on free-tier quota from each provider. The tool sits at an intersection between browser utility and multi-LLM management, similar in principle to unified chat interfaces like Perplexity or Poe, but native to the browser itself rather than a separate web application. As of October 2026, the project has received minimal mainstream visibility outside Hacker News and remains in early-stage testing. No formal documentation, feature roadmap, or user community is evident beyond the Chrome Web Store listing. The extension requires users to trust an unknown third party with API keys or OAuth credentials for each LLM, which raises security and data-handling questions that remain unaddressed in available materials.
Pros
- Unifies access to multiple LLM APIs (GPT, Claude, Gemini) in one sidebar without switching tabs
- Browser-native Chrome extension deployment requires no separate installation or account management overhead
- Appears lightweight and does not interrupt existing browser workflow
Cons
- Launched as Show HN with minimal adoption metrics or user reviews available for verification
- Feature set and pricing model remain unclear from available documentation
- No evidence of active development or community support beyond initial launch
Who it is for
- Best for: Users who routinely consult multiple LLM services and want faster context-switching within the browser..
- Avoid if: You need a polished, well-documented product with a proven track record and dedicated support..
Who this is for
Early adopters and power users who are comfortable experimenting with minimal-viable-product tools. Browser-heavy knowledge workers (researchers, writers, developers) who run multiple LLM queries daily and want a consolidated interface without leaving their browser tab.
Who should skip this
Teams requiring SLA guarantees, data privacy certifications, or audit trails. Users who prefer stability and comprehensive documentation. Organisations bound by data residency or compliance requirements, since the extension's server infrastructure is undocumented.
Verdict
Thinkbeside is an experimental browser convenience tool for users willing to tolerate missing documentation and undefined support in exchange for unified LLM access. It is far too new and undocumented to recommend for professional or sensitive work. Early adopters should test it in isolated, non-critical browsing contexts until the project matures and publishes transparent data-handling and security policies.
