MaxAI.me and Merlin AI are two of the most installed AI Chrome extensions of 2026. Both are chat sidebars; both lean on quick-action menus over selected text; both compete on price. Clicky is the third extension in this post and the only one of the three that does not have a sidebar at all — it is a push-to-talk voice assistant pinned to a single DOM element. We are putting them side by side because users routinely ask “which of these three should I install?” The honest answer depends on what you do all day; this post lays it out.
Three extensions, two categories
MaxAI and Merlin both belong to the chat-sidebar with quick-actions category — install one of them, select text on any web page, see a floating menu (“Rewrite,” “Translate,” “Summarise,” “Reply”), click a button, get an answer in a panel. They differ on model mix, price, and polish, but the shape is the same.
Clicky belongs to the targeted voice assistant category. We mapped the difference in detail in Browser Copilot vs Browser Agent and the wider field in Best AI Chrome Extensions for SaaS Workflows (2026). The short version: chat sidebars optimise for breadth and text-in/text-out work; targeted voice assistants optimise for latency and DOM-grounded answers about a specific page.

What MaxAI.me is built for
MaxAI.me’s defining feature is the floating quick-action menu. Select text anywhere — an email, a Slack message, a help-desk reply, a paragraph in a Notion doc — and a small toolbar appears with one-click verbs: Rewrite, Translate, Summarise, Explain, Reply, and a handful of saved prompts you can configure. It is easily one of the fastest text-processing interfaces shipped in a Chrome extension, and the design choice to put the menu inline rather than locked in a sidebar is what keeps it sticky.
The sidebar is there too — full chat with model picker, prompt library, image generation — but the quick-action menu is what users open the extension for. As of August 2026, MaxAI fronts GPT, Claude, Gemini, and a handful of other models with managed billing. The free tier is usable for occasional work; the paid tier unlocks higher daily caps and the more expensive models.
Where MaxAI loses: it does not point at on-page elements. If your question is “where is X on this dashboard,” the sidebar can describe the spot but cannot draw on it. It also requests broad host permissions to make the quick-action menu fire on every site — the engineering reality of that interaction model.
What Merlin AI is built for
Merlin AI is the value-tier entrant in the chat-sidebar bracket. Functionally, the feature list overlaps heavily with MaxAI: chat sidebar with model picker, quick-actions on selected text, translation, summarisation, document upload. The differentiator is price — Merlin’s paid plans land below most of the competition, and the free tier monthly query cap is generous enough to be a real working tier rather than a trial.
Merlin’s public posture has consistently been “the affordable everyday AI sidebar,” and that is genuinely what it delivers. If you have decided you want a chat sidebar in your browser and you do not need a specific power-user feature, Merlin is a defensible default. Like MaxAI it requests broad host permissions and stores conversation history server-side; the privacy posture is the standard sidebar-extension trade.
What Clicky is built for
Clicky is none of the above and that is the point. There is no sidebar to open, no quick-action menu, no model picker. You hold the Alt key, ask a question about whatever is on screen, and let go. A voice answer plays through ElevenLabs and a halo paints on the DOM element that matters. Free tier runs on Claude Haiku 4.5; paid runs on Claude Sonnet 4.6.
The job is operating an interface, not processing text. “What does this slider do?”, “Where is the export button?”, “Is there an invoice in this account?”, “Which one of these toggles disables notifications?” The halo persists through reflows because it tracks a CSS selector, not a screen position. The permission scope is activeTab only, fired strictly on Alt-press. Memory is session-only.
Where Clicky loses: it will not draft a long-form email, run a translation pipeline, summarise a 30-page PDF, or generate an image. Those are deliberately outside its scope. If your work is text-heavy, MaxAI or Merlin is the better install.
Privacy and permissions
The two sidebars are similar on this dimension; Clicky is the outlier.
MaxAI and Merlin both declare permissions that allow them to “read and change your data on all websites” — the broad-host pattern that makes their quick-action menus possible. Both store conversation history server-side to power continuity features. Their privacy policies are reasonable for what they do; both products are widely deployed at companies whose security teams have approved the trade.
Clicky requests only activeTab and stores nothing server-side beyond the in-tab session. That is not better in absolute terms — it is a different bet. The bet is that for a SaaS-heavy machine, the right shape is a narrow tool that fires on demand rather than a broad tool that runs in the background. We covered the framework for thinking about this in Chrome Extensions That Do Not Track You.
Pricing and plans
All three have free tiers; the paid ladders sit close enough that price alone should not decide the install.
MaxAI.me, as of August 2026, lists a free tier with daily caps on basic models and paid plans starting around $10/month billed annually for higher quotas and access to the more expensive models. Merlin AI offers a free tier with a monthly query cap and paid plans starting around $14/month billed annually with unlimited basic-model usage and capped advanced-model usage.
Clicky is priced in EUR: Explorer free (10 push-to-talk turns per day), Pro at 19€/month billed annually (228€/year) with high daily quota and Sonnet 4.6 reasoning, and Team at 99€/month billed annually (1188€/year) for five pooled seats and human support. Full breakdown on the landing page.
Which to pick
- Pick MaxAI.me if your day is dominated by processing inbound text — replying to emails, rewriting Slack messages, translating help-desk tickets, summarising long pages you already opened. The quick-action menu is genuinely the fastest interface for that work.
- Pick Merlin AI if you want a defensible everyday chat sidebar at the lowest price in the category, and you do not have a specific power-user need that one of the others handles better.
- Pick Clicky if your day is operating SaaS dashboards (HubSpot, Salesforce, Stripe, Notion, Jira, Linear), if you want voice-first interaction with hands-free answers, or if your security context rules out broad-host extensions.
Many users install one of MaxAI or Merlin plus Clicky. That covers both jobs without overlap: a sidebar for text in / text out, a voice + halo for in-app navigation. They do not compete for the same moment.
Frequently asked questions
Is Clicky a MaxAI.me alternative?
Only for the “answer a question about the page I am looking at” subset of MaxAI’s use. If you use MaxAI for text rewriting, translation, the quick-action menu, or long-form chat, Clicky will not replace it — those are deliberately outside Clicky’s scope.
Is Clicky a Merlin AI alternative?
Same answer. Merlin’s defining job is the chat-sidebar experience at a low price. Clicky does not have a chat sidebar. For everyday in-browser chat, Merlin or MaxAI is the right install; for in-app voice Q&A with DOM grounding, Clicky is.
Which has the smallest privacy footprint?
Clicky, by a clear margin — activeTab-only permission, fired strictly on Alt-press, with no server-side conversation storage. Both MaxAI and Merlin use broad-host permissions and persistent server-side history, which is the standard trade for sidebar extensions and not a privacy failing per se. It is a different engineering shape with different consequences.
Can I install all three?
Yes, though it is overkill. Install the one sidebar you prefer (MaxAI or Merlin, not both) and Clicky alongside it. The two sidebars compete with each other; Clicky does not.
