CogniMemo Extension
CogniMemo's @cogni inline AI prompt bar streams model replies into any Chrome text field, backed by a personal memory graph.
The @cogni trick is genuinely useful: you prompt a model without leaving the field, and the reply lands at your cursor. What follows is less reassuring. Thirty-one users, one rating, a non-trader developer record, and a 7.0.0 release with no documented changes. It costs nothing to try, but don't make it your system of record.

Skip CogniMemo if you need shared team memory, offline AI on a non-Chrome browser, or a vendor you can hold to a support contract — a 29-user extension with one rating is not a system of record.
CogniMemo costs nothing and ships as a single free Chrome Web Store listing. That puts it below the paid second-brain tools it competes with functionally: Mem.ai and Rewind.ai both charge subscriptions for more polish and maintenance, and they are aimed at buyers who will pay for a maintained roadmap. CogniMemo fits an individual who wants the inline workflow for $0 and accepts a thin, single-developer track record instead.

What is CogniMemo Extension?
CogniMemo Extension — CogniMemo's @cogni inline AI prompt bar streams model replies into any Chrome text field, backed by a personal memory graph. Best for Heavy ChatGPT or Claude users who want inline prompts without switching tabs, Researchers capturing selected web text and chat interactions into one searchable place, Writers and knowledge workers who want saved context at hand inside any web text field. Free to use.
CogniMemo is a Chrome extension that drops an AI prompt bar inside whatever text field you're already typing in. Trigger it with @cogni, write your prompt after the slash, and the reply streams back into that same input, textarea, or rich editor. It's built for heavy chatbot users, researchers, and note-takers who would rather not bounce between a draft and a separate chat window. The second half is memory. CogniMemo syncs memories from external sources like X/Twitter and OpenAI interactions into a personal memory graph, and it grabs content from any web page when you select text. Whatever the assistant draws on can be stored, organized, and recalled later, so your second brain grows out of your browsing and chat history instead of a separate notebook app. The Chrome Web Store listing shows version 7.0.0, updated January 2, 2026, at a 389KiB footprint. It declares website content as its data scope and states your data isn't sold to third parties. Distribution is early: the page shows 31 users and a single 5.0 rating, and the developer is registered as a non-trader, so EU consumer rights don't apply. Against subscription tools like Mem.ai and Rewind.ai, CogniMemo trades polish and maintenance for immediacy. It sits inside the field you're working in. Those rivals don't, and they cost money. Use CogniMemo as a fast inline helper, not as the place your knowledge base lives.

Behind the verdict
The pitch here is narrow and sensible. Type @cogni in any text box, get a streaming reply in place, and skip the tab dance that eats minutes every hour if you use ChatGPT or Claude all day. Pick it when your main annoyance is the copy-paste loop between a draft and a chat window. We'd reach for CogniMemo when the field itself is the workspace: drafting an email, filling a form, editing a doc in a web editor. The memory graph side is the part to treat carefully. Pulling in X/Twitter posts and OpenAI interactions sounds nice, and selecting text on a page to save it is a fast capture move, but a 31-user extension with one rating is not where your notes should live permanently. Export or duplicate anything you'd miss. The @cogni trigger and the model-agnostic routing, ChatGPT, Claude, Gemini, or DeepSeek, are the reason to install. That routing is also the limit: CogniMemo is a courier. If a host model is down or your key/access changes, the inline bar has nothing to send to. Pass on this if you need offline AI, shared team memory, or a vendor who answers support tickets. A non-trader developer record means no EU consumer rights, and there's no evidence of a maintained release rhythm. The January 2, 2026 version 7.0.0 update documents no changes, so you can't tell what improved. The closest alternative is just keeping a chat tab pinned and pasting. Mem.ai and Rewind.ai are the paid, polished options, with stronger maintenance and features CogniMemo doesn't have. We wouldn't cross-shop them directly: they solve capture and recall, CogniMemo solves in-field prompting. In practice, treat it as a free convenience layer and keep your real notes elsewhere.
Models under the hood
as of 2026-10-24
Limitations
- CogniMemo is a Chrome browser extension, so it requires Chrome to function.
- The listing shows a very small user base (26 users) and a single 5.0 rating, so there is almost no track record to judge reliability by.
- Version 7.0.0 was updated January 2, 2026 with no documented changes, so you cannot tell what that release altered.
- The declared data scope is website content — the broadest permission category available to an extension — and the developer is listed as a non-trader, meaning EU consumer rights do not apply to contracts with this developer.

GeneratedReal-world workflow fit
Concrete scenarios for the personas CogniMemo Extension actually fits — and what changes day-one when you adopt it.
You're filling a long textarea in a browser form and want an answer without leaving it. You type @cogni plus your prompt, choose a model, and the reply streams into the field. You select supporting text on a source page to capture it.
Outcome: Draft written in place with no tab switching, and the source passage saved to your memory graph for later recall.
You save X/Twitter posts and prior OpenAI interactions into CogniMemo's memory graph, then later type @cogni in any field to pull that context back while drafting.
Outcome: Your saved context is searchable from any text box instead of trapped in separate apps.
You need to compare phrasing across models. Using the same @cogni trigger, you route one prompt to ChatGPT and another to Claude or Gemini from inside the same field.
Outcome: Model comparison happens without opening a single chat tab.
Use cases
- Search saved notes and past AI chats by typing @cogni in any text field
- Save X/Twitter posts into your personal memory graph for later recall
- Archive AI conversations so you can search them again
- Draft or explain content in any website's text box using your own saved context
- Select text on a web page to capture and store it in your memory graph
Setup time & first value
How long it actually takes to get something useful out of CogniMemo Extension — broken out by persona, not the marketing-page minute.
Individual browser user: install the 389KiB extension from the Chrome Web Store and start typing @cogni in any text field immediately — first value in under a minute. Building a useful memory graph takes longer, since it depends on how much you sync from X/Twitter, OpenAI interactions, and selected web pages over the following days.
Switching to or from CogniMemo Extension
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From browser chat tabs: keep ChatGPT, Claude, Gemini, or DeepSeek open as you do today, but start typing @cogni in the field you're writing in instead of pasting replies across.
- ↗To Mem.ai or Rewind.ai: export or re-capture what matters, since a Chrome extension's memory graph has no documented handoff to those platforms.
