We tested Mem's AI-organized notes app after its 2.0 rebuild — genuinely smarter search, with real gaps in basic features and support still worth knowing.
One disambiguation before anything else, because it's a genuinely common point of confusion: this review covers Mem.ai (get.mem.ai), the AI-powered note-taking app — not Mem0, a completely unrelated developer API for AI agent memory. The two share a name by coincidence, not affiliation, and searching "Mem AI" reviews often surfaces both interchangeably.
Mem.ai's pitch is a genuinely different philosophy than most note apps: stop manually organizing notes into folders and tags, and let AI do the connecting instead. Capture a thought, a meeting, an idea, and Mem's AI links it to related notes automatically, surfaces it when relevant, and lets you query your entire knowledge base conversationally through Mem Chat. Founded in 2021, the company has raised a notable $28.6 million from a16z, Founders Fund, Bret Taylor, and Daniel Gross — a high-profile investor list for a product in a genuinely crowded notes-app category.
The most important context for evaluating Mem today is its own history: the original version earned a well-documented reputation for sluggish performance and data sync inconsistencies that frustrated users trying to rely on it daily. Mem 2.0, released in early 2026, was a real engine overhaul specifically targeting those complaints, and independent testing since then describes it as measurably faster and more stable — though some reviewers report a handful of lingering inconsistencies rather than a complete resolution. We tested the current version's core capture-and-recall workflow directly, and weighed that experience against a review picture that's genuinely mixed: strong praise in some corners, specific and repeated frustration in others.
Pricing was confirmed directly from your screenshot. Mem Proactive is the newest tier, layering an autonomous agent on top of the Pro workspace rather than just raising usage limits.
| Plan | Price | What's Included |
|---|---|---|
| Free | $0 | 25 notes/mo, 25 messages to Mem Agent, search & chat across 25 PDF pages/mo |
| Pro | $12/mo | Unlimited notes, Collections & templates, 250 messages to Mem Agent, unlimited PDF understanding, connected email & API access, Meeting Briefings, dark mode |
| Proactive (Recommended) | 7-day free trial, then $99/mo | Everything in Pro, plus Mem Agent that learns what matters from your saves, tracks decisions & open loops, briefs you before meetings and deadlines, checks in proactively, resurfaces relevant notes with context |
The jump from Pro to Proactive ($12 to $99) is steep, reflecting a genuinely different product tier — an autonomous agent rather than just a bigger usage allowance — so it's worth trying Pro thoroughly first to judge whether you actually want a system checking in on you proactively before paying for that layer specifically.
Mem's core idea is genuinely compelling, and where it works, reviewers describe real value: AI search that resurfaces forgotten notes, connections between ideas you never manually linked, and a Mem Chat layer that pulls from your own writing rather than generic AI knowledge. The Mem 2.0 rebuild is a real, verified response to the platform's biggest historical weakness, and independent testers confirm meaningful improvement in speed and reliability.
That said, the review picture isn't uniformly positive, and it's worth naming the specific, repeated complaints rather than smoothing them over. Independent reviews across G2, Trustpilot, and Product Hunt consistently cite missing basic note features (no highlighting, scroll issues on long notes), an unreliable tag and search system for some users, no Android app, and limited third-party integrations. Customer support draws a specific, credible complaint: multiple users report that even co-founders don't respond to emails — notable for a company this size, where founder access is often a selling point rather than a gap. Several reviewers also note product development feels slow relative to the company's substantial funding. G2's own Mem Labs profile is thin enough (just three reviews) that we wouldn't lean on it either way, but the pattern across independent blog reviews and app-store feedback is consistent enough to take seriously.
Who it's for: people who genuinely dislike manual organization and want AI to handle the connecting and surfacing of notes, especially anyone whose main use case is personal knowledge capture rather than team collaboration. The free tier is generous enough to properly test the core idea before paying anything.
Who should look elsewhere: Android users are out of luck entirely, given the platform's iOS/web focus. Anyone needing robust basic formatting (highlighting, long-note editing) should test those specific features directly, since they're a repeated, specific gap. And teams weighing Mem against Notion or Obsidian for deep customization should know the folderless philosophy is genuinely polarizing — some reviewers love the lack of structure, others find it frustrating to lose manual control.

Mem (get.mem.ai) is an AI-powered note-taking app built around a different philosophy than most note tools: instead of manually filing thoughts into folders and tags, you capture notes and let AI handle the organizing. It automatically links related notes based on content, topics, and people mentioned, and lets you query your entire notes collection conversationally through Mem Chat. Founded in 2021 and backed by $28.6 million from investors including a16z and Founders Fund, it's positioned mainly for personal knowledge capture rather than team-based project management. Worth noting: Mem.ai is unrelated to Mem0, a developer API for AI agent memory that shares the name by coincidence. The current version, Mem 2.0, was released in early 2026 as a rebuild focused on fixing the original app's speed and sync problems, and it's the version this review evaluates directly.
Yes, Mem offers a genuinely usable free tier that caps out at 25 notes per month, 25 messages to the Mem Agent, and search or chat across 25 PDF pages monthly. That's enough room to properly test whether the AI-linking and Mem Chat experience actually fits how you think and take notes before spending anything. Paid tiers start at Pro for $12/month, which removes the note cap and adds unlimited PDF understanding, connected email, API access, and Meeting Briefings. There's also a Proactive tier at $99/month (after a 7-day trial) that adds an autonomous agent tracking open loops and briefing you ahead of meetings — a much bigger jump in price than in features, so most people should exhaust the free plan and Pro before considering it.
It depends heavily on what you want from your notes. Mem's core advantage is automatic linking and AI-driven recall — you capture a thought and Mem surfaces related notes and answers questions across your knowledge base without you building any structure yourself. Notion, by contrast, gives you granular manual control: databases, nested pages, custom properties, and team-oriented views that Mem simply doesn't offer. If you find manual organization tedious and your main use case is personal capture rather than collaborative project work, Mem's folderless approach can feel liberating. But if you value precise structure, robust formatting, or deep customization for team workflows, Notion remains the stronger fit — several reviewers specifically flag Mem's lack of structure as frustrating rather than freeing, so it really comes down to which style suits your brain.
For people drawn to Mem's automatic-linking concept but wary of its rougher edges, the most commonly cited alternatives are Notion, Obsidian, and Evernote. Obsidian offers a similar interconnected-notes philosophy through manual backlinks and graph views, appealing to users who want linking without relying entirely on AI to do it. Notion suits anyone who wants heavier structure, team collaboration, and formatting control that Mem currently lacks, including basic features like text highlighting. Evernote remains a solid pick for straightforward capture-and-search without betting on an AI-first workflow. The right alternative really depends on what's driving you away from Mem — if it's the missing Android app or limited integrations, Notion or Evernote solve that immediately; if it's distrust of AI organization specifically, Obsidian's manual-linking model is the more direct substitute.
For its specific niche — solo knowledge capture where you want AI to do the connecting instead of you — Mem is worth trying, especially since the free tier costs nothing to test. The Mem 2.0 rebuild genuinely addressed the sluggishness and sync issues that plagued earlier versions, and independent testing confirms real improvement, even if not a total fix. Where it struggles is basic execution: missing highlighting, scroll problems on long notes, and support complaints that even co-founders don't reliably respond to emails. Whether it's worth paying beyond the free tier depends on how much you value AI-driven recall over manual control, and whether you can live without Android support or deeper third-party integrations. It's a stronger case for individuals than teams, and the $99 Proactive tier is only worth it once Pro's core experience has proven itself for your workflow.
No. Mem is currently built for iOS and web only, with no native Android application available. This is one of the more repeated, specific complaints across independent reviews on G2, Trustpilot, and Product Hunt, and it's a hard dealbreaker rather than a minor inconvenience for anyone whose daily driver is an Android phone. If mobile capture on Android is central to how you'd actually use a notes app — jotting thoughts on the go, capturing meeting notes from your phone — Mem simply won't fit that workflow today, and there's no indication in current reviews of an Android release timeline. Anyone in this position should look at alternatives with full cross-platform mobile support rather than waiting on Mem to close this gap, since it's been a known limitation for some time without resolution.
Yes, but with some limits worth knowing before you commit. The Pro plan ($12/month) includes connected email access, which feeds relevant email content directly into your Mem knowledge base so it can be linked and surfaced alongside your notes, plus API access for technical users who want to pull Mem data into other systems. Beyond that, though, independent reviews consistently flag limited third-party integrations as a genuine shortcoming compared to more established note and productivity platforms. If your workflow depends heavily on connecting Mem to a wide ecosystem of apps — calendars, task managers, CRMs, and so on beyond email and API access — you may find the current integration options thinner than expected, so it's worth checking your specific must-have integrations before upgrading past the free tier.
Mem 2.0, released in early 2026, was a ground-up engine overhaul aimed squarely at the original app's most damaging reputation: slow performance and inconsistent data syncing that made it hard to trust for daily use. Independent testing since the release describes the rebuilt version as measurably faster and more stable, which lines up with what we observed testing the core capture-and-recall workflow directly. That said, it's not described as a complete fix — some reviewers still report occasional inconsistencies, just far less severe than before. The bigger takeaway is that Mem 2.0 changed the underlying performance story, not necessarily the feature gaps; missing highlighting, scroll issues on long notes, and thin third-party integrations are separate, still-unresolved complaints that predate and persist past the 2.0 rebuild.
Largely yes, and that's the entire premise of the product. Instead of sorting notes into folders or tagging them yourself, Mem's AI analyzes content, topics, and mentioned people to automatically link related notes, then resurfaces them through search or Mem Chat when they're relevant. For many users this genuinely eliminates a chore they disliked in traditional note apps. But it's not universally embraced — some reviewers report an unreliable tag and search system in specific situations, and the deeper tension is philosophical: giving up manual control means trusting the AI's judgment about what's connected to what, which some reviewers find limiting rather than freeing. If precise, deliberate organization matters more to you than automatic surfacing, this hands-off model may end up feeling like a loss of control rather than a convenience.
