What Glimpse — Chat with the web is
What Glimpse is
Glimpse is a browser extension (Chrome and Firefox) that adds an AI assistant understanding the content of any page you visit and answering questions about it without copying text into a separate chat window. The tool is built on OpenAI technology (GPT-3.5 and GPT-4), and its distinguishing feature is that the conversation doesn't reset with every new tab — context persists across tabs, setting it apart from simpler, one-off page summarizers.
Key features
A browser sidebar lets you ask questions about the currently open page, request a summary of a long article, or fix grammar in a text fragment without leaving the tab. The cross-tab conversation continuity means context from one page can carry over when moving to the next, which is useful for research spanning several sources at once. The extension also functions as a lightweight ad blocker, so the pitch is twofold — cleaner browsing and an AI assistant in one package. Support covers essay writing, grammar correction, brainstorming, language translation, topic explanation, and advanced research with academic paper sourcing.
Who it's for
Glimpse appeals to people reading a lot of content online — students, researchers, journalists — who want to ask a question about an article without switching to a separate ChatGPT tab and manually pasting a text fragment. Those who value context persisting across tabs will find a more convenient workflow here than in typical extensions that reset the conversation on every refresh.
Use cases
In practice, Glimpse works well for quickly summarizing a long article before deciding whether it's worth reading in full, for fixing grammar in a text fragment directly on the page, or for research spanning several sources, where context from the first page helps make sense of the second. Translating fragments of foreign-language pages without leaving the tab is another typical scenario.
Pricing and business model
The extension is free, built on commercial OpenAI models available at no extra charge from the developer. It's worth checking current availability in official extension stores before installing, though — the tool had roughly 7,000 users before being removed from the Chrome Web Store in March 2024, which may mean limited availability through official channels.
Limitations and what to watch for
The Chrome Web Store removal is a signal worth verifying before relying on this tool — availability through Firefox Add-ons may be more current, but always check the extension's status directly in the store before building a daily workflow around it.
AI notes from browsing sessions
Glimpse doesn't offer a lasting conversation archive as a notebook — context persists across tabs within one browsing session, but it doesn't save as an organized ai notes entry for later. Anyone who wants valuable page summaries to land as ai notes in a searchable archive has to copy the answers by hand into a separate notes app.
Bottom line
Glimpse is a browser extension pairing a page-aware AI assistant with an ad-blocking feature, with context persisting across tabs — but no lasting archive. Anyone who wants ai notes from browsing sessions to land automatically in a file store should consider a tool built around that workflow.
Comparison with SumizAI
Glimpse and SumizAI operate in entirely different contexts. Glimpse is a browser overlay helping you understand web page content on the fly. SumizAI is a separate notebook built around a conversation with AI, turning answers worth keeping into these notes — Markdown files in a vault the user owns, with their own API key to one of 7 providers. Anyone who wants an assistant for quickly understanding pages in the browser will pick Glimpse; anyone who wants these notes from AI conversations to build a lasting archive will find SumizAI the better-fitting tool.

What SumizAI is
A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk.
A vault is a directory holding base.md, a generated table of contents up to six levels deep, and a notes/ folder with one .md file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist.
The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used.
Every answer kept this way becomes one of these ai notes, ready to search again months later without hunting back through old chats.

Where they differ
- Glimpse — Chat with the web is a place to have the conversation. SumizAI is not a chatbot — the conversation is the input, not the product. What comes out of it is a
.mdfile with a title, a place inbase.mdand a duplicate check against the notes already in the vault. If you only want to talk to a model, you do not need SumizAI. - Glimpse — Chat with the web is free and SumizAI costs a dollar a month after a seven-day trial that takes no card. A dollar is what it costs to run accounts and licences without reselling the model; if free is the requirement, Glimpse — Chat with the web wins that row outright.
- AlternativeTo's description of Glimpse — Chat with the web does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard
.mdfiles to a folder you picked, and an unpaid account can still export all of them. - Glimpse — Chat with the web runs in the browser. SumizAI is a desktop and mobile application, and on the desktop the vault is a folder on your own disk rather than a document in someone's cloud.
Which one to pick
Reasons to pick Glimpse — Chat with the web
- it costs nothing

Reasons to pick SumizAI
- the notes you want already exist inside conversations with an AI model
- you want the filing — title, chapter, duplicate check — to happen without you
- you want the result as plain
.mdfiles in a folder you picked - you would rather pay your AI provider directly than have a note app resell the model
