Best Sider alternative in 2026

Four Sider alternatives profiled with pricing checked July 2026 — model access, platforms, tier names, one honest limitation each, and when Jarvis (getjarvis.eu) is the wrong pick.

How we put this list together: Jarvis is our product — this site is getjarvis.eu — so treat the #1 spot as an editorial opinion with an obvious interest, and check the sourced facts yourself. Every price and tier name on this page was checked in July 2026 against the vendors' own public pricing pages (sider.ai/pricing, monica.im/pricing, getmerlin.in/pricing, perplexity.ai/pro). Where a vendor does not publish something as static text — Sider's free-tier existence (no free plan card currently appears on its pricing page), Perplexity's exact non-annual monthly list price and full native-app platform list, Merlin's iOS-vs-Android split — we say so rather than quoting a number. Each named limitation is drawn from the same vendor pages, not from third-party reviews.

1. Jarvis — An on-demand, screen-aware desktop assistant. Press Cmd+/ on macOS or Ctrl+/ on Windows and a floating bar screenshots the active window, answers questions about it, and acts in your apps through 30+ OAuth connectors (Gmail, Slack, Notion, Linear, GitHub, Figma, Microsoft 365). Inference runs on cloud frontier models (Anthropic, OpenAI, Google) routed through Jarvis's GDPR-aligned backend, with persistent memory across sessions — there is no browser sidebar or extension, by design. Pricing: Free: $0 — 40 requests/week. Pro: $16/month ($144/year billed annually). Unlimited: $32/month. Checked July 2026. Platforms: macOS (Apple Silicon and Intel), Windows 10+, Linux. Known limitation: Cloud-only inference — Jarvis needs an internet connection and has no offline mode, and because it isn't a browser extension it doesn't do in-page tricks like a Chrome sidebar (on-page translation overlays, a pinned side panel next to the tab). Pick Jarvis if: you want one shortcut that makes AI aware of your whole desktop — native apps, PDFs, code, dashboards, not just browser tabs — with a real free tier and connectors that take action. 2. Sider — Browser-based AI sidebar/extension, with companion desktop and mobile apps, offering chat, page summarization, translation, an agentic browser tool ("Claw"), and image/video generation across multiple frontier models. Pricing: Individual plans, monthly billing, checked July 2026: Lite $25/month (15,000 credits/month), Pro $50/month (35,000 credits/month), Max $100/month (80,000 credits/month, selectable tier); yearly billing advertised at 17% off plus a free cloud-computer credit. No free-tier plan card appears on the current pricing page — entry price is $25/month. Platforms: Chrome/Edge extension, iOS, Android, macOS, Windows (per Sider's own Apps footer list). Known limitation: No free-tier plan is offered on the current pricing page — the cheapest paid tier is $25/month, materially higher than the entry price of every other tool on this list. Pick Sider if: you mainly work inside Chrome/Edge and want one sidebar for chat, page summarization, translation, and a browser-automation agent, and don't need a native macOS/Windows floating assistant with app connectors. 3. Monica — All-in-one browser-first AI assistant (with macOS/Windows/iOS/Android apps) combining chat, writing tools, image/video generation, and a growing set of agent features (Deep Research, Browser Operator, Create Slides). Pricing: Checked July 2026: Free $0 (40 basic-model accesses/day, limited trials of image/video/ChatPDF/AI Agent, no advanced-model access); Pro $8.3/month billed annually at $99/year (5,000 basic-model queries/month, 200 advanced-model queries/month, 1,500 Advanced Credits); Max $16.6/month (flash-sale 33% off; billed $199 or $299/year depending on term) with unlimited basic/advanced model access and 4,500 Advanced Credits; Ultra $82.9/month billed annually at $995/year (unlimited everything, 20,000 Advanced Credits, priority support). Platforms: Chrome extension, macOS, Windows, iOS, Android. Known limitation: On the Free plan, advanced models (GPT-5.5, Claude, Gemini Pro) are not accessible at all — only basic models — and image/video generation is a 'limited trial' only. Pick Monica if: you want the deepest free tier of the browser-AI category to try chat plus writing/translation tools before paying, and are fine with a browser-sidebar-first (not native-desktop-screen-aware) workflow. 4. Merlin — Chrome-extension-first AI assistant (with a web app and mobile app) bundling chat across 10+ models, Projects/knowledge bases, an analyst/spreadsheet mode, and Chrome-integrated writing tools for Gmail, X, LinkedIn, and more. Pricing: Checked July 2026: Free $0/year (limited daily access to basic and Plus-level models, basic image generation, limited Chrome extension features); Pro $19/month, billed $228/year on the annual plan (effectively no annual discount on Pro); Teams $15/seat/month billed annually at $180/seat/year, 2-seat minimum, adds team management, larger context window, usage dashboard, SOC2/GDPR/ISO27001 claims. Platforms: Chrome extension, web app, mobile app (per Merlin's own 'Mobile app features' comparison rows); no macOS/Windows native desktop app is listed on the pricing/feature page. Known limitation: Merlin's own pricing page states: 'All features share a combined fair usage limit, so heavy use of one reduces availability for others' — Pro is not a flat unlimited plan; usage across chat, image, and agent features draws from one shared cap. Pick Merlin if: you want the widest raw model menu (10+ models) inside a Chrome extension plus Gmail/X/LinkedIn writing helpers, and don't need a native-desktop floating assistant or deep app connectors. 5. Perplexity — AI answer engine that returns cited, current web-search-backed answers, now expanded with 'Perplexity Computer' (an agentic task/build tool) alongside its web, mobile, and desktop apps. Pricing: Checked July 2026: Free plan exists (unspecified limits on the fetched pricing page); Pro $17/month ('or equivalent, when billed annually'; includes Computer access, 4,000 bonus credits, and model selection across Claude Sonnet 5, Gemini 3.1 Pro, Sonar 2); Max $167/month (same annual-equivalent framing; 10,000 monthly credits, 35,000 bonus credits, unlimited usage, priority access). The exact monthly, non-annual list price was not separately displayed on this page. Platforms: Web, described as having Perplexity Computer plus app access; the exact native macOS/Windows/mobile app list was not itemized on the fetched pricing page. Known limitation: Perplexity is built around search/answer sessions and its 'Computer' agent, not an always-on native floating assistant over other apps — it has no on-page/on-screen 'point at what I'm looking at' capture flow the way OS-level assistants do; the pricing page frames it entirely as answers, credits, and Computer builds. Pick Perplexity if: your core need is fast, cited, current-web research and report/app building via Computer, not floating-bar screen awareness or 30+ app connectors for act-on-your-behalf tasks.

Why people switch: Sider currently has no free tier; Desktop-wide, not browser-only; Connectors that take action, not just read; Simple subscription tiers, not a credit meter; It never claims to run offline.

Pick a competitor instead if: You want a Chrome/Edge sidebar with a browser-automation agent — That's Sider's actual product — one panel for chat, page summarization, translation, and Claw automating web tasks, with model switching across GPT, Claude, DeepSeek, and Gemini. Jarvis has no browser-sidebar mode; it's a desktop floating bar instead. You want the deepest free tier in this category before paying anything — Monica's free plan (40 basic-model accesses/day) is the most generous entry point here — Sider currently has no free tier at all, and Jarvis's free plan is capped at 40 requests/week. You want the widest raw model menu in a browser extension — Merlin exposes 10+ models (GPT-5.2, Claude, Gemini, Grok, Kimi) inside a single Chrome extension, plus Gmail/X/LinkedIn writing helpers. Jarvis routes cloud frontier models automatically rather than letting you hand-pick a vendor per message. You want cited, current-web research, not screen capture — If the job is fast, sourced answers about what's happening right now on the web — or building something with Perplexity Computer — Perplexity is purpose-built for that. Jarvis's screenshot-and-act workflow is aimed at your own screen and apps, not open web research.

What is the best Sider alternative in 2026? Jarvis for on-demand screen-aware help across every desktop app with real app actions; Sider itself remains the strongest pick if you want a Chrome/Edge sidebar with a browser-automation agent; Monica for the deepest free tier; Merlin for the widest raw model menu in a browser extension; Perplexity for cited, current-web research.

Is there a free Sider alternative? Yes. Jarvis has a free plan (40 requests/week), Monica has a free tier (40 basic-model accesses/day), Merlin has a free plan, and Perplexity has a free plan (limits not itemized on its pricing page). Sider's own current pricing page shows no free plan card on its Individual tab — the cheapest tier is $25/month.

Which Sider alternatives work outside the browser? Jarvis is a native desktop app for macOS (Apple Silicon and Intel), Windows 10+, and Linux, and works over any window — not just web pages. Sider itself and Monica ship companion mobile and desktop apps alongside their extensions, but their core surface is the browser sidebar. Merlin is Chrome-extension-first with a web and mobile app.

Does Jarvis have anything like Sider's Claw browser agent? No — Jarvis doesn't automate web pages inside a browser tab. It reads whatever native app or window is on screen when you press Cmd+/ (Ctrl+/ on Windows) and can act through 30+ OAuth connectors like Gmail, Slack, Notion, and Linear. If browser-page automation specifically is the job, Sider's Claw is built for that.

Does Sider have a free plan? Not currently. As of the pricing page we checked in July 2026, Sider's Individual plans start at Lite for $25/month — no free-tier plan card is shown, which is a change from how the category is often positioned.
