Sider
Sider puts a multi-model AI sidebar in Chrome and Edge for chat, page summaries, translation, and browser automation.
Buy Sider for Hand and Code, not the long tail. Running multi-step tasks across public sites inside your own logged-in sessions is awkward to replicate with a chat-only assistant, and persistent page restyling is a real trick. The bundled PDF, slides, and image utilities are convenient but each has a sharper dedicated rival.

Skip Sider if your work is project-level software development or long-form professional writing, where a real IDE or a dedicated writing app will beat a browser sidebar every time.
Running Sider across desktop browsers plus iOS and Android under one account is the point of the product, so seat sprawl is easy to miss when a whole team adopts it tab by tab.
Sider sells as a freemium browser extension with a stated education plan, so it sits at the low-cost end against full-suite AI subscriptions and against per-tool stacks. Compare it to paying separately for a chat assistant, a PDF reader, a slide generator, and an image editor — the bundle math is the argument. Compare it to a dedicated writing or coding tool and the value proposition flips: those cost more but do one job materially better.

What is Sider?
Sider — Sider puts a multi-model AI sidebar in Chrome and Edge for chat, page summaries, translation, and browser automation. Best for Shoppers and researchers comparing prices or specs across Amazon, Best Buy, and eBay in one Hand run, Students and academics who summarize, translate, and cite sources without leaving the browser, Multi-model users who want GPT, Claude, and Gemini in a single sidebar. Pricing not published.
Sider embeds a multi-model AI assistant in a browser sidebar for Chrome and Edge, so help is available on the page you're already reading. You pick GPT, Claude, or Gemini per task, and the assistant uses on-screen content from web pages, PDFs, YouTube videos, or images for summarizing, explaining, translating, or extracting. July 2026 user reviews keep citing two reasons people stay: quick access to several AI bots in one place and pulling text out of images. The browser work splits into three roles. Hand runs a plain-language instruction across sites you're logged into, such as a price comparison pulling from Amazon, Best Buy, and eBay. Code restyles or rewrites a page from a description and remembers the change for later visits. Chat covers everyday reading, translation, and drafting. The toolbox around that core is wide: Wisebase, a personal knowledge base with Deep Research and Scholar Research modes; an Apps shelf with ChatPDF, AI Slides, AI Essay Writer, Web Creator, and Math Solver; translators for text, images, and PDFs; an image stack covering Nano Banana Pro, Background Remover, Inpaint, Photo Eraser, and Image Upscaler; and Rec Note plus Audio To Text for recording and transcription. One account spans Chrome, Edge, macOS, Windows, iOS, and Android. Sider aims at students, researchers, writers, and knowledge workers who live in a browser and want one assistant across many small jobs. Versus single-model sidebar extensions, it swaps depth in any one discipline for breadth across several.

Behind the verdict
Where Sider earns its place is the sidebar itself. Having GPT, Claude, and Gemini one click from whatever page you're on, with the assistant able to read that page, is the pitch July 2026 reviewers keep repeating, and it holds up for reading-heavy days. We'd reach for it when the job is summarize this, translate that, pull the text out of this screenshot. The two features worth paying attention to are Hand and Code. Hand takes a plain-language instruction and works across sites you're already logged into, which is the closest thing here to real browser automation. Code rewrites or restyles a page from a description and remembers it for next visit. Neither is a developer tool, but both are useful for shoppers, researchers, and anyone who wants a cluttered site to behave. Pass on Sider if you need depth. The Apps shelf (ChatPDF, AI Slides, AI Essay Writer, Web Creator, Math Solver) and the image stack (Background Remover, Inpaint, Photo Eraser, Image Upscaler) are competent, and a June 2026 reviewer praised image text extraction as a daily helper, but each has a dedicated tool that goes further. Heavy long-form writing or coding belongs in a dedicated app. The closest alternative is a single-model sidebar extension. You trade multi-model choice and the Hand/Code automation for a narrower, often cheaper tool. Teams wanting custom deployment or dedicated security controls should look elsewhere; Sider is a consumer-shaped product across Chrome, Edge, macOS, Windows, iOS, and Android. In practice, the account sprawl is the caveat. One login across six platforms is convenient until you're juggling Wisebase, translators, and the image tools in the same session. Treat Sider as a fast front door for small jobs rather than the place you finish them.
Models under the hood
as of 2026-09-01
Limitations
- Sider is a browser layer, not a platform.
- Code edits and restyles pages you visit — it does not give you a code editor, repo management, or project-level tooling.
- Its cross-site automation depends on your logged-in browser sessions, so sites with strong anti-bot defenses can interrupt Hand mid-task.
- The bundled toolbox (Wisebase, Deep Research, ChatPDF, AI Slides, AI Essay Writer, Web Creator, the image tools) is broad but each piece trails the best single-purpose option in its category.
- Heavy writing work is better served by a dedicated writing tool, and heavy development work needs a real IDE.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Sider actually fits — and what changes day-one when you adopt it.
Opens a dense PDF and a long YouTube lecture in two tabs, asks Sider Chat to summarize both, translates one Spanish-language source, then uses Scholar Research and ChatPDF to pull quotable passages with citations into Wisebase.
Outcome: Source reading that would take an afternoon collapses into a single sidebar session, with the notes stored in Wisebase for the draft.
Prompts Sider Hand: 'Help me build a gaming PC under $1,500. Compare GPU, CPU, and motherboard prices across Amazon, Best Buy, and eBay.' Hand navigates the three sites in the logged-in browser, extracts the RTX 4070 Super, Ryzen 7 7800X3D, and ASUS ROG Z790 Hero listings, and returns a priced build.
Outcome: A cross-site price comparison that would mean six tabs and a spreadsheet comes back as a single $1,499.92 build sheet.
Uses Sider Code to describe the change — hide the sidebar, enlarge the font, strip the banner — and Sider restyles the page in real time. The change is remembered on the next visit.
Outcome: A page they use daily gets customized once, in plain words, without a userscript or a browser extension of their own.
Use cases
- Summarize a long article, PDF, or YouTube video without leaving the tab
- Run multi-site research — compare GPU, CPU, and motherboard prices across Amazon, Best Buy, and eBay — from one prompt
- Draft essays, blog posts, and marketing copy with structure and citations
- Explain a code snippet or generate code from natural language
- Translate a webpage, image, or PDF on the fly
- Build a presentation with AI-generated slides
- Edit an image by removing the background, erasing text, or inpainting an area
- Build a simple site with Web Creator without coding
Setup time & first value
How long it actually takes to get something useful out of Sider — broken out by persona, not the marketing-page minute.
For a solo user: install the extension from the Chrome Web Store, sign in once, and Sider is live on every tab in under five minutes. Adding the iOS, Android, macOS, and Windows apps to share the same account takes another few minutes per device. Teams should expect a short rollout to walk users through the Chat / Hand / Code split, since Hand's behavior depends on each person's own logged-in
Switching to or from Sider
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From ChatGPT or Claude in a separate tab: install Sider, sign in, and keep using GPT, Claude, or Gemini inside the sidebar on whatever page you are already reading.
- →From a separate PDF chat tool: point Sider Chat at the same PDFs and use ChatPDF inside the bundle instead of a second subscription.
- →From a screenshot-and-translate workflow: replace it with AI Translator / Image Translator / PDF Translator on the source page directly.
- →From a standalone presentation builder: use AI Slides to generate the deck, then continue editing where you already do.
- ↗To a dedicated writing app: export drafts and long-form documents out of Sider once the sidebar's drafting tools hit their ceiling.
- ↗To a real IDE: move any project-level code work off Sider Code — it edits pages, not repositories.
- ↗To a full enterprise AI platform: if you need custom deployments, dedicated security controls, or admin governance, plan a move to a platform built for that.
