## Poly

Poly is a cloud file browser built around the idea that you should be able to ask for a file the way you would ask a colleague. Instead of memorizing folder structures, you describe what you need in natural language and Poly searches across images, video, audio, PDFs and documents — even finding a specific scene inside a clip or a paragraph inside a report. It can also chat about your files, transcribe interviews, and generate new images from folders of references.

Beyond search, Poly behaves like a full file platform. It offers multiple view modes from feed and grid to tree and gallery, automatic tagging, complete version history, public sharing, shared drives with separate permissions, and a native-feeling interface with keyboard shortcuts and drag-and-drop. A desktop app syncs Poly files with your local file system, and both web and desktop support offline work that syncs back when you reconnect.

Privacy is handled with encryption at every stage and a Hide from AI control so you can keep sensitive material out of the assistant's reach. Poly is currently presented as a beta with a waitlist, and pricing is not published publicly, so interested teams should join the waitlist or contact the company directly.

**Pricing & Plans:** Contact for pricing. Poly is currently offered through a beta with a join-waitlist flow, and we did not find a published self-serve pricing page during review. Reach out to the Poly team or join the waitlist for access and cost details.

- **Natural-Language AI Search:** Find files by image, concept, phrase, color, face or content similarity, and search inside documents and media for the exact page, paragraph or clip.
- **Chat and Summarize Files:** Ask questions about your files and get answers, summaries and transcriptions, with long-context reading across thousands of files in one conversation.
- **Intelligent File Management:** Store, browse and organize files with Feed, Grid, Icon, Tree, Column and Gallery views, automatic tagging and full version history.
- **Desktop Sync and Offline:** Access and sync Poly files through your local file system, with both web and desktop apps working offline until changes sync.
- **Privacy and Sharing Controls:** Encryption on device, in transit and in the cloud, plus a Hide from AI toggle and granular sharing and permissions for shared drives.

**Strengths:** Finds files by concept, color, face and content similarity, not just filename; Can search inside files for a precise scene, page or clip; Chats about and summarizes your documents, media and recordings; Desktop sync, offline support and rich view modes make it feel like a real file manager

**Limitations:** Currently in beta with a join-waitlist flow, so general availability may be gated; Some advertised capabilities such as collaborative conversations are marked 'coming soon'; No published self-serve pricing, so costs require contacting the team; AI indexing of large libraries means users should deliberately use the Hide from AI controls for sensitive files

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
