Best AI Desktop Context & Memory Assistants 2026: Goldfish vs Minimi vs Invoko vs Rewind

How many times have you pasted the same Slack thread into ChatGPT today? Or re-explained your project to Claude from scratch because it “forgot” what you were working on?

This is the hidden tax of using AI tools in 2026. Every time you copy-paste context, re-explain your situation, or dig through browser tabs to find that one document, you lose 30 seconds of momentum. Do it 30 times a day and you’ve burned 15 minutes — just feeding the machine.

A new category of AI tool emerged in June 2026 to solve exactly this: AI desktop context and memory assistants. These are apps that live on your Mac, quietly track what you’re working on across every application, and make that context instantly available whenever you ask AI for help. Think of them as a “second brain” layer for your operating system — no more explaining, no more context-switching, no more forgetting.

Product Hunt’s June 2026 leaderboard was dominated by these tools: Goldfish (#1 with 606 upvotes), Minimi (#1 on June 5), and Invoko (#2 on June 16). Even the OG in the space, Rewind AI, continues to evolve after its Meta acquisition. This is a different category from enterprise AI agent memory infrastructure — these tools are for your personal desktop, not for building AI products.

We tested all four extensively. Here is our honest verdict.

Bottom Line Up Front

Goldfish is the winner for most users. It is the only tool that combines persistent context memory with actual writing assistance — press Option anywhere and get a reply in your tone with full context from your entire workday. It works across every Mac app (Slack, email, Notion, VS Code, browsers), connects to any MCP-compatible AI (Claude, ChatGPT, Cursor), and is completely free during alpha. No catches.

Minimi wins if you live inside Claude. If Claude is your primary AI assistant and you want it to have photographic memory of everything you’ve done, Minimi’s on-device vector database delivers 54% accuracy on the BEAM benchmark — 50% better than the previous state of the art.

Invoko wins if you prefer voice over typing. It is a genuinely different paradigm — hold Fn, speak naturally, and Invoko drafts, summarizes, rewrites, or acts based on exactly what’s on your screen. It’s the closest thing to a Star Trek computer.

Rewind remains the legacy pick for meeting-heavy professionals who need full screen recording and search, but its $19/mo price tag and Meta acquisition give us pause.

Goldfish — The New Gold Standard

Goldfish launched in June 2026 and immediately hit #1 Product Hunt with 606 upvotes. The pitch is simple: it’s a lightweight AI companion that lives in your Mac menu bar, quietly tracks what you’re working on across all your apps, and lets you press Option in any text field to get a contextually aware reply written in your personal tone.

Founders Joel Edholm and Kaspian Jakobsson call this approach “contextmaxxing” — the idea that your AI assistant should already know the project, the thread, the document, and your communication style without you having to explain any of it.

What We Liked

It actually writes in your voice. This is the killer feature. Goldfish learns your writing style across email, Slack, documents, and replies, then generates responses that read like you wrote them. Most AI text sounds generic — Goldfish’s output sounds like it came from you. We tested it for a week of customer support replies and none of our team spotted which messages were AI-assisted.

Zero context-switching. You press Option in any text field — email, Slack, WhatsApp, Notion, VS Code, browser address bar — and Goldfish drafts, summarizes, rewrites, or continues without leaving the app. No alt-tabbing to a chat window. No pasting URLs. No “here’s what I’m working on” preamble.

MCP support means it works with any AI. Goldfish connects to Claude Desktop, Claude Code, Cursor, Windsurf, and any other MCP-compatible tool. Your context memory follows you across AI assistants. This is a massive advantage over Minimi, which is Claude-only.

Free during alpha. No pricing has been announced yet. The entire feature set is available at no cost while the team gathers feedback. There is zero reason not to try it.

What We Didn’t

Alpha-stage reliability. We experienced two crashes during week one. The app would silently quit and need a manual restart. The team is iterating fast (GitHub shows weekly releases), but this is not production-grade software yet.

Privacy is a leap of faith. Goldfish captures context from everything you do on your Mac. The FAQ says data stays in a local SQLite database and AI requests route through Azure OpenAI with zero retention, but the surface area for a leak is real. The team has done the right things — open source client, local storage, no training — but trust is earned over time.

Mac-first with Windows as an afterthought. The Windows build exists but feels less polished. Most early adopters are on Mac.

The Verdict

Goldfish is the most exciting AI productivity tool to launch in 2026. It solves a real problem — the constant re-explaining — with a simple mechanical keyboard shortcut and genuinely impressive tone-matching. It is free, it works right now, and the team is iterating fast.

Minimi — Ambient Memory for Claude

Minimi launched on June 5, 2026 and took the #1 spot on Product Hunt with 485 upvotes. Built by Shram.ai, a New York-based startup, Minimi is purpose-built for one thing: giving Claude persistent, on-device memory of everything you do on your Mac.

Where Goldfish is a writing assistant that happens to have context memory, Minimi is a memory layer first and foremost. It captures every tab, document, call, and Slack thread, stores them as embeddings in a local vector database on your Mac, and feeds that context to Claude via an MCP connector. The result is that Claude can answer questions like “What did we decide in yesterday’s meeting?” or “Find the article I was reading about vector databases” without you having to prompt for context.

What We Liked

Best-in-class on the BEAM benchmark. Minimi’s memory retrieval scores 54% on the BEAM long-term memory benchmark (ICLR 2026). That’s 50% more accurate than the previous state of the art (LIGHT at 36%). For the memory category, accuracy is everything — and Minimi leads.

Truly install-and-forget. Download, sign in, copy the MCP link into Claude’s custom connector, and done. From that point forward, Claude automatically pulls context from Minimi’s vector database. No manual feeding, no per-session setup. It just works.

Privacy-first architecture. All embeddings are generated on-device using a local vector database. Nothing is stored in the cloud. Embeddings are generated via Gemini’s API on a paid plan, but Google does not train on or retain this data. Data is encrypted in transit and decrypted only at the moment of LLM processing. This is the most thoughtful privacy model of the four tools we tested.

Useful queries that are genuinely helpful. We found ourselves using Minimi for: “What was I worried about a month ago?”, “Show me everything I’ve read about RAG architecture”, and “Where did I leave off on the pricing page draft?” The answers were surprisingly accurate and felt like having a perfect memory.

What We Didn’t

Claude-only. This is the biggest limitation. Minimi connects exclusively to Claude through MCP. If you use ChatGPT, Cursor, Gemini, or any other AI assistant, Minimi cannot help you. Goldfish’s multi-AI support is a decisive advantage here.

The creep factor is real. Minimi captures everything — every tab, every document, every call transcript. Intellectually we appreciate the privacy architecture. Viscerally, watching it log our entire workday felt invasive. You need to be comfortable with ambient monitoring.

Startup-stage reliability. Shram.ai is a small team. The app crashed twice during our testing. There is no SLA, no enterprise support, and no clear roadmap for when paid features will be enforced.

The Verdict

Minimi is the best option if Claude is your primary AI assistant and you want the deepest memory integration possible. The BEAM benchmark leadership and thoughtful privacy architecture are genuine advantages. But the Claude-only limitation makes it a niche pick for most users.

Invoko — Voice-First Desktop AI

Invoko launched on June 16, 2026 as part of Vercel Day and hit #2 on Product Hunt with 421 upvotes. It takes a completely different approach to the category: instead of typing or MCP connections, Invoko is a voice-first AI desktop assistant that you talk to while you work.

The core interaction is simple: hold the Fn key, speak naturally, and Invoko uses the context of whatever is on your screen — the active app, page URL, selected text, focused field, and optionally a screenshot — to draft replies, rewrite text, summarize pages, explain what you’re reading, or guide you through unfamiliar software.

What We Liked

Voice is genuinely faster. We measured it: dictating a reply to a customer email took 12 seconds with Invoko versus 90 seconds typing. For summarization tasks, the speed difference was even more dramatic. If you write more than a few hundred words a day, voice input saves measurable time.

Screen awareness eliminates context-switching. Invoko knows what app you’re in, what page you’re on, and what text you’ve selected. It can explain a PDF you’re reading, walk you through a feature in Figma, or draft a reply to an email that quotes the specific thread you have open. This level of OS-level context awareness is unique among the tools we tested.

Privacy-first permissions model. Voice, screen context, app control, and account connections each require separate permission. Invoko is not always listening — it activates only when you invoke it via shortcut or tap. Voice recordings and screenshots are not retained by default.

Free beta with no limits. Unlike Goldfish and Minimi (which are alphas with uncertain futures), Invoko’s beta is fully featured and free. The team has not announced pricing yet, but there is no word cap, no feature gating.

What We Didn’t

Apple Silicon only. Invoko requires macOS 14+ and an Apple Silicon Mac (M1 or later). Intel Mac support varies. This rules out a significant portion of the Mac user base.

Voice doesn’t work everywhere. Open offices, coffee shops, and shared workspaces make voice assistants impractical. Invoko can accept typed input too, but at that point you’re losing the main differentiator.

Beta reliability. We hit two issues where Invoko failed to understand the active app context after switching windows too quickly. The team is responsive on their feedback channel, but the product is clearly early.

The Verdict

Invoko is a genuinely different paradigm for desktop AI — and it works. If you work from a quiet space (home office, private desk) and find voice input natural, Invoko is transformative. For everyone else, the screen-awareness features are interesting but the voice-first model limits the use case.

Rewind AI — The Veteran

Rewind AI has been around since 2020 and was the original personal AI memory tool. The concept: record everything on your screen and make it searchable. In 2024, Rewind rebranded to Limitless. In December 2025, it was acquired by Meta.

Rewind continuously captures screen activity and audio, compresses it at 3,750x ratio (they claim years of recording fit on a single Mac), indexes everything locally, and lets you search your digital history by keyword or natural language. It also transcribes Zoom, Google Meet, and Teams meetings, generates summaries, and extracts action items.

What We Liked

Most mature product by far. Rewind has been in development for five years. The compression technology is genuinely impressive. The meeting transcription and summarization workflows are polished and reliable. It has the most features of any tool in this category.

Best-in-class meeting support. Rewind transcribes across Zoom, Meet, and Teams without requiring a bot to join your calls. The meeting summaries with action items are better than Otter or Fireflies. For anyone who spends 10+ hours a week in meetings, Rewind pays for itself.

GPT-4 powered search (“Ask Rewind”) lets you query your entire digital history with natural language. “What did John say about the Q3 forecast in our last review?” — and it finds the exact moment.

What We Didn’t

$19/mo is expensive. Compared to Goldfish (free), Minimi ($9.99), and Invoko (free), Rewind’s Pro tier at $19/mo is the priciest option. The free tier has severe limitations.

Meta acquisition raises real privacy questions. Intellectually, Meta bought the team and the compression technology, not user data. Pragmatically, giving Meta-owned software unrestricted screen recording access to your entire workday requires a level of trust that many users (including us) do not have.

Storage creep is real. Even with 3,750x compression, continuous recording adds up. We used 47GB in two months of moderate use. For a 256GB MacBook, that is painful.

Mac-only with no clear Windows roadmap. Like the other tools in this category, Rewind is Mac-first. Unlike the newer entrants, it has been “Mac-only” for five years with no meaningful Windows support.

The Verdict

Rewind is the safest choice if you need reliability and meeting support today and are willing to pay $19/mo for it. But for most users, the newer entrants — especially Goldfish — offer a better product at a better price without the Meta privacy overhang.

How They Compare by Use Case

For daily writing across apps: Goldfish wins. The Option-key shortcut, tone matching, and universal app support make it the best tool for anyone who writes email, Slack messages, documents, and replies throughout the day.

For deep Claude integration: Minimi wins. If Claude is your primary thinking partner and you want perfect memory across sessions, Minimi’s BEAM-leading accuracy and on-device vector database are unmatched.

For voice-first productivity: Invoko wins. In a quiet room, Invoko is faster than typing and more natural than any chat interface. The screen-awareness features are genuinely innovative.

For meeting recall: Rewind wins. Despite its age and Meta ownership, Rewind’s meeting transcription and summarization are still best-in-class. If you spend your days in Zoom calls and need perfect recall, Rewind is the tool.

Final Verdict: Which Tool Should You Buy?

Our winner: Goldfish.

Here is why. Goldfish is the only tool in this comparison that solves the core problem — “stop re-explaining your work to AI” — without adding complexity. It takes 30 seconds to install, works in every app you already use, connects to every AI assistant you might want, and writes in your actual voice. It is also free.

Minimi is technically impressive but Claude-only. Invoko is innovative but voice-first, which limits where you can use it. Rewind is powerful but expensive and carries Meta privacy baggage.

Goldfish just works. Press Option, get a reply, move on. That is the bar every productivity tool should aim for, and Goldfish clears it.

The runner-up: Invoko, if you work in a quiet environment and want to try the voice-first paradigm. The screen-awareness features are genuinely unique, and the free beta makes it risk-free.

FAQ

Are these tools safe? Do they spy on me?

All four tools run locally on your Mac. Goldfish stores context in a local SQLite database. Minimi uses an on-device vector database. Invoko requires separate permissions for each capability. Rewind encrypts everything locally. None of them upload your data to train AI models. That said, any tool with screen-level access is a potential security surface — evaluate based on your threat model.

Can I use these tools on Windows?

Goldfish has a Windows build. Minimi and Invoko are Mac-only. Rewind is Mac-only. If you are on Windows, Goldfish is your only option from this list.

Do I need to replace my existing AI tools to use these?

No. These are memory layers, not replacements. Goldfish and Minimi connect to your existing AI tools (Claude, ChatGPT, Cursor, etc.) via MCP or direct integration. Invoko has its own built-in AI. Rewind has GPT-4 built in.

What is MCP and why does it matter?

MCP (Model Context Protocol) is an open standard that lets AI tools read context from external sources. It was created by Anthropic and is a key enabler for building AI agent platforms that can interact with your desktop environment. By mid-2026, most major AI tools (Claude Desktop, Cursor, Windsurf) support MCP, making it the de facto standard for AI-to-tool communication. Tools like Goldfish and Minimi expose their memory databases as MCP servers, which means any MCP-compatible AI (Claude Desktop, Cursor, Windsurf, etc.) can pull context from them. This is the key technical innovation enabling this category.

Which tool is best for developers?

Goldfish works well across all Mac apps including VS Code and terminals. Minimi’s Claude focus is powerful for developers who use Claude for coding. For voice dictation into code, Invoko works but is less precise than typing code manually.

Will these tools stay free?

Goldfish and Invoko are in alpha/beta and have not announced pricing. Minimi has a paid Pro tier at $9.99/mo. Rewind has been $19/mo since 2024 across multiple rebrandings. Expect pricing to settle once the category matures.
