Rewind.ai Review: What It Was, and Why It Shut Down

Is Rewind.ai still worth using in 2026?

No — Rewind.ai isn't a product you can download anymore. The company rebranded to Limitless in 2024, shifted its focus to a wearable AI pendant, was acquired by Meta in December 2025, and formally sunset the original Rewind Mac app: the last update disabled all screen and audio recording starting December 19, 2025. This review covers what Rewind actually did, why it mattered, and what to use instead now.

At a glance

If you found this page searching for a tool that records your screen and lets you search your past digitally, that specific product no longer exists in the form Rewind originally shipped it. What follows is an honest account of what it was, what it got right, and what replaced it.

What Rewind.ai actually was

Rewind was founded by Dan Siroker (previously co-founder of Optimizely and a veteran of Obama's 2012 re-election campaign's data team) with the pitch of building "a bionic memory" — software that continuously recorded what happened on your Mac's screen and, separately, audio from meetings and calls, then made all of it searchable later in natural language. The core promise: instead of trying to remember which webpage had that statistic, or what exactly was said fifteen minutes into a call, you could search for it the way you'd search Google, and Rewind would surface the exact screenshot or transcript segment.

Rewind ran locally on macOS (Apple Silicon Macs specifically, at least for the compressed-recording feature) and stored recordings on-device rather than in the cloud, which the company leaned on heavily in its marketing as a privacy differentiator — your screen history wasn't being uploaded to a third-party server for storage, even if some processing (like transcription or AI summarization) touched Rewind's or a partner's servers. It never shipped an official Windows or Linux version, which shaped who could actually use it from day one.

Under the hood, Rewind combined its own compression and search-indexing work with third-party AI models (OpenAI's models, among others, for summarization and chat-style querying of your recorded history) rather than training a foundation model from scratch. Its real engineering achievement was less "we built a new AI model" and more "we made continuously recording and compressing a full macOS session over weeks technically and storage-wise feasible" — a hard systems problem independent of the AI layer on top.

Pricing and feature details below reflect Rewind's last known state before the app was discontinued — treat this as historical record, not a live product page, since there's nothing left to sign up for.

Features that actually differentiated it

Continuous local screen recording. Rewind quietly captured what was on your screen at intervals, compressed it efficiently enough to store weeks or months of history without consuming enormous disk space, and indexed it for search. This was the headline feature and the reason it got early attention from productivity and memory-augmentation enthusiasts.

Meeting and call recording with transcription. Rewind could record audio from meetings (including both sides of a call, not just your own microphone, on supported setups) and generate searchable transcripts — useful for people who wanted a record of what was actually said in a call without manually taking notes.

Natural-language search across your history. Instead of scrolling back through a timeline, you could type a question like "what was that pricing number from Tuesday's call" and get pointed to the relevant moment, screenshot, or transcript excerpt.

AI summarization and "ask" features. Rewind layered AI-generated summaries and a chat-style query interface on top of your recorded history, letting you ask follow-up questions about things you'd seen or heard rather than just keyword-searching.

Local-first storage as a privacy stance. Recordings lived on your device by default, which the company positioned as materially different from cloud-recording competitors — a claim that mattered to privacy-conscious users specifically because full-screen recording is about as sensitive a data category as exists on a personal computer.

Who it was actually for

• Knowledge workers on Apple Silicon Macs who wanted a safety net for "what did I read/see/hear" questions, without changing how they worked day to day.
• People in a high volume of meetings who wanted call transcripts and searchable recall without manually taking notes each session.
• Early adopters of the "AI memory" category comfortable trading continuous recording for near-perfect recall — a trade-off that was never going to appeal to everyone.
• Windows and Linux users were never served — macOS exclusivity meant a large share of potential users couldn't evaluate it at all.

Pros and cons

Integrations and ecosystem

Rewind didn't build a broad third-party integration ecosystem the way productivity suites do — its value was largely self-contained: record, index, search. It didn't offer a public developer API for outside apps to build on, and there was no dedicated Zapier or Slack integration; its main "integration" was sitting on top of everything else you already did on your Mac, since it recorded the screen rather than plugging into specific apps individually. That was arguably both a strength (nothing to configure app-by-app) and a limitation (no way to pipe recorded data into other workflows programmatically).

What happened — the pivot to Limitless

In 2024, the company launched Limitless, an AI wearable pendant designed to record and transcribe in-person conversations and meetings throughout the day, extending the "personal memory" concept beyond the desktop to real-world conversations a laptop app could never capture. The company rebranded around this hardware-first identity, and the original Rewind Mac app kept operating for a while under the Limitless umbrella rather than disappearing immediately.

That transition period ended in December 2025. Limitless announced it had been acquired by Meta, and alongside the acquisition came a clear wind-down of the legacy software: the company stopped selling the Pendant as of December 5, 2025, and the Rewind app began sunsetting, with an update disabling all screen and audio capture starting December 19, 2025. Existing recordings made before that date remained accessible through the Limitless Desktop and Web apps into 2026, but no new recording has been possible since — the core feature that made Rewind, Rewind, is gone. Existing customers were reportedly moved to a free "Unlimited" tier rather than continuing to pay a subscription, consistent with an orderly shutdown of a legacy product rather than active continued development.

It's worth being precise here, because this is a genuine three-act story rather than a simple rename: Rewind (2023, software-only, Mac screen/audio recording) became Limitless (2024, pivoted to a wearable pendant device), which was then acquired by Meta (December 2025), leading to the Pendant being discontinued and the Rewind app's recording features being switched off entirely. None of that means the underlying "AI personal memory" idea was flawed — wearable AI recall devices remain an active category — only that this specific software product, in the form searchers are likely looking for, no longer exists.

Where it was a strong fit (while it existed)

Rewind made the most sense for Mac-based knowledge workers and heavy meeting-attendees who wanted a low-effort safety net for recall, and who were comfortable with the privacy trade-offs of continuous local recording. For that narrow but real audience, it solved a problem few other tools addressed as directly.

Where to think twice (and what to use instead now)

There's nothing left to sign up for, since Rewind's recording features are disabled — but a few things matter if you found this page researching the category:

• If you want an AI wearable for recording in-person conversations, Limitless's Pendant is what the company pivoted to, though it's also no longer being sold as of December 5, 2025 — check Limitless's own site for current availability.
• If you want meeting transcription without hardware, tools built specifically around call recording (rather than full-screen capture) are a more actively maintained category to look at now.
• If you need Windows or Linux support, Rewind never served you in the first place, so nothing has actually changed for you here.
• If you're evaluating any AI memory or recall tool today, verify vendor claims about local-only storage and data retention against the current privacy policy directly — this is a fast-moving category where product direction can change entirely within a couple of years, as Rewind itself shows.

The bottom line

Rewind.ai was a genuinely interesting early entry in the "AI personal memory" category — continuous, local, searchable recall of what you saw and heard on your Mac. But it never expanded past macOS, the company's strategic bet moved to hardware within about a year, and the whole product line was wound down following Meta's acquisition of Limitless in December 2025, with recording disabled that same month. If you're researching it now, there's no download to evaluate — only a case study in how quickly a well-received AI product can be discontinued when a company's strategy shifts.

Frequently asked questions

Is Rewind.ai still available to download?

No. The original Mac app's recording features were disabled starting December 19, 2025, as part of the company's wind-down of the legacy Rewind/Limitless software following Meta's acquisition of Limitless.

What happened to Rewind.ai?

It rebranded to Limitless in 2024 and pivoted toward a wearable AI pendant. Limitless was then acquired by Meta in December 2025, after which the company stopped selling the Pendant and disabled all screen and audio recording in the original Rewind app.

Was Rewind.ai free?

It offered a free tier with limited history retention, alongside paid plans for more storage and features, before the product was discontinued. Exact historical pricing tiers are no longer published on an active pricing page, so treat specific figures as unverifiable after the fact.

Is Rewind the same thing as Limitless?

Effectively yes, in terms of company lineage — Limitless is the rebranded, hardware-focused continuation of the company that built Rewind, not a separate competitor. The original Rewind Mac app continued to exist under the Limitless brand for a period before being sunset.

What happened to my old Rewind recordings?

According to Limitless's own announcement, existing recordings made before the December 19, 2025 cutoff remained accessible through the Limitless Desktop and Web apps into 2026, even though no new recording is possible.

What's a good alternative to Rewind.ai now?

For in-person conversation and meeting recall via hardware, Limitless's own Pendant was the direct successor, though it's also no longer being sold as of December 5, 2025. For meeting transcription specifically, dedicated call-recording and note-taking tools are a more actively maintained alternative to evaluate.

Was Rewind.ai available on Windows?

No. It was macOS-only for its entire life as an active product, with no official Windows or Linux release ever shipped.
