CogniMemo Extension

CogniMemo Extension

Free Chrome extension that turns any text field into an inline AI prompt bar with a searchable memory graph.

68/100MonitorFreeFree

The inline @cogni flow is a genuinely useful idea — prompt AI without leaving the field you're typing in, and keep a memory graph on the side. But 34 Chrome Web Store installs, one rating, and a 7.0.0 release with no documented changes mean you're adopting a hobby project, not infrastructure. Try it for free if the workflow appeals; don't make it your system of record. If you need shared memory, support SLAs, or an actively maintained roadmap, look at Mem.ai or Rewind.ai instead, and expect to pay for them.

About CogniMemo Extension

FreeIntermediateNo APIWeb

CogniMemo is a free Chrome extension that turns any text box into an AI prompt bar. Type @cogni inside an input, textarea, or rich editor, follow it with your prompt, and the extension sends it to your chosen model and streams the reply back into the same field. It routes to ChatGPT, Claude, Gemini, or DeepSeek, so you can switch models without leaving the page you're on — no tab juggling, no copy-paste. The second half of the product is memory. CogniMemo can sync interactions from external sources such as X/Twitter and OpenAI into a personal memory graph, and you can capture anything from a web page just by selecting text. That material is stored, organized, and recalled later, so answers can be grounded in what you've already saved instead of starting cold each session. The extension also rides along as a floating assistant across sites, keeping the @cogni trigger within a keystroke wherever you type. It's a small install at 389KiB, running version 7.0.0 (updated January 2, 2026), and it's free. Data handling is disclosed as website content, not sold to third parties and not used for creditworthiness or lending decisions. The trade-off is scale. The Chrome Web Store listing shows 34 users and a single 5-star rating. Version 7.0.0 shipped with no documented changes, so the January 2, 2026 release is functionally unchanged. For knowledge workers, researchers, and heavy ChatGPT users tired of losing context between sessions, CogniMemo takes a model-agnostic, browser-native approach. Subscription rivals like Mem.ai and Rewind.ai are more mature and better staffed, but they cost money and don't live inside your text fields. CogniMemo is the free, clever, lightly-adopted alternative.

Behind the Verdict

CogniMemo's core bet is placement: instead of opening a chat tab, you type @cogni directly into whatever input, textarea, or rich editor you're already using, and the model's reply streams back into that same field. The model router spans ChatGPT, Claude, Gemini, and DeepSeek, so switching providers doesn't require leaving the page. That is a real workflow improvement over the copy-paste loop most people still run. The memory side is where it gets interesting and where it gets thin. You can sync memories from X/Twitter and OpenAI interactions and capture web page content by selecting text, all of which lands in a personal, searchable memory graph. In principle that grounds the assistant in material you've already saved. In practice the graph, the recall quality, and the sync reliability are undocumented — there is no vendor changelog entry explaining the sync pipeline, no release notes on retrieval behavior, and no public docs site we could find. You're trusting the extension's own description. On trust signals, the Chrome Web Store disclosure is narrow and specific: the extension handles website content, is flagged Accessibility, and the developer declares data is not sold to third parties, not used for unrelated purposes, and not used for creditworthiness or lending decisions. The developer is listed as a non-trader, which matters for EU buyers — consumer rights do not apply to contracts with this developer. Scale is the honest problem. 34 users and one 5-star rating is not adoption; it's a launch that didn't spread. Version 7.0.0, updated January 2, 2026, arrived with no documented changes, which is a maintenance signal rather than a feature signal. Nothing here suggests an active roadmap, a support contract, or team features — there are no shared or collaborative memory capabilities documented. Where it fits: an individual knowledge worker, researcher, or writer who lives in Chrome, is comfortable with a 389KiB extension reading website content, and wants inline model-agnostic prompting plus a personal capture layer without paying a subscription. Where it doesn't: teams needing shared memory, anyone who wants offline AI, anyone needing an actively maintained tool with a support path, or buyers who need a detailed, published privacy policy before granting website-content access.

Real-world workflow fit

Concrete scenarios for the personas CogniMemo Extension actually fits — and what changes day-one when you adopt it.

Solo researcher

You find a passage on a web page, select it to capture it into your memory graph, then type @cogni in a notes field and ask for a summary grounded in what you've saved.

Outcome: Your findings and the AI's synthesis live in the same place instead of scattered across tabs and clipboard history.

Writer drafting on any site

While typing in a rich editor, you type @cogni followed by a rewrite request, and the reply streams back into the same field without opening a chat tab.

Outcome: Drafting stays in flow, with model choice across ChatGPT, Claude, Gemini, or DeepSeek available inline.

Heavy ChatGPT user

You sync your OpenAI interactions and X/Twitter posts into the memory graph, then recall them later by prompting from any text box on any site via the floating assistant.

Outcome: Past sessions stop being disposable and become material the assistant can reference.

Where the pricing makes sense

The company stage and team size where CogniMemo Extension's pricing actually pencils out — and where peers do it cheaper.

CogniMemo is free, so there is no pricing tier to grow into — there is also no paid support, SLA, or team plan to buy if you need one. Against it, Mem.ai and Rewind.ai charge subscriptions and are more mature. You're trading money for maturity, and paying nothing means you get a 34-user extension with one rating and a developer who has not identified as a trader.

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.

Install from the Chrome Web Store — the extension is 389KiB, so the download and install are quick. Getting to first value depends on how much you feed the memory graph: inline @cogni prompting works immediately after install in version 7.0.0, but grounding answers in your own data requires syncing OpenAI or X/Twitter interactions or capturing pages by selecting text first.

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.

Migrating in
  • From copy-pasting into a chat tab: install the extension and type @cogni in the field you're already working in instead.
  • From a browser bookmark collection: select text on each page to capture it into the memory graph instead of bookmarking.
  • From scattered ChatGPT history: sync your OpenAI interactions into CogniMemo so past sessions become searchable.
Migrating out
  • To Mem.ai or Rewind.ai: export or re-capture your saved material into the rival's knowledge base, then uninstall the extension.
  • To plain ChatGPT or Claude in a browser tab: stop using @cogni and revert to copy-paste, accepting the loss of inline insertion.
  • To a notes app: manually re-save captured selections, since no bulk export path is documented.
