For a desk-bound founder, Screenpipe wins: 24/7 local screen capture from $25/month with a free tier, on Mac, Windows, and Linux. Limitless wins in-person conversations with its pendant and free 20-hour monthly transcription. The tiebreaker comes from Daniel Kahneman's Thinking, Fast and Slow: pick the tool that counters your remembering self's peak-end distortions where you actually work.
By Friday my memory of Tuesday is a story, not a record, and I say that as someone who builds AI systems for a living. Daniel Kahneman spent a career documenting why in Thinking, Fast and Slow: the remembering self that runs your weekly review is not the experiencing self that lived the week. It scores episodes by their peak and their ending, neglects duration entirely, and then hands you a confident, distorted summary you make decisions with. A founder reviewing their own week is a textbook unreliable witness. That is the actual problem the new crop of AI memory tools is selling against, and the two serious contenders solve it from opposite ends.
Screenpipe is the desk-side answer. It records your screen and audio 24/7, extracts text from every frame through accessibility APIs with OCR as a fallback, and stores everything locally in SQLite and MP4 files on your own machine. It runs on macOS, Windows, and Linux, works offline, and lets you point the AI layer at local models through Ollama or at cloud models if you choose. The paid app starts at $25 a month or $250 a year, with a free tier that keeps capture and search on-device, plus a REST API for wiring your work history into automations. Limitless comes from the opposite direction: it grew out of Rewind, and its center of gravity is a wearable pendant that captures in-person conversations — the meetings, walks, and hallway decisions no laptop ever hears. Its free plan includes 1,200 minutes (20 hours) of transcription per month with AI notes, summaries, and search included; Screenpipe's own comparison page lists the pendant at $99 plus a $20 monthly subscription, though I note that source is a competitor.
To judge them I scored both against criteria taken straight from Kahneman, because "which tool remembers better" is really a question about which of your distortions most needs correcting.
| Criterion (from Thinking, Fast and Slow) | Screenpipe | Limitless |
|---|---|---|
| Complete record of desk work (counters peak-end and duration neglect) | 5 | 2 |
| Captures in-person conversations (where founders actually decide) | 2 | 5 |
| Data control (local-first, auditable, works offline) | 5 | 2 |
| Cost to start seriously (free tier value) | 4 | 4 |
| Fits a multi-machine, cross-platform reality | 5 | 2 |
| Total (out of 25) | 21 | 15 |
The scorecard favors Screenpipe for the founder whose decisions happen across Slack, terminals, and browser tabs — which is most of us, most of the time. But the criteria expose an honest exception: if your consequential conversations happen at dinners, on walks, or across a table, the pendant is the only device in this comparison that hears them, and no amount of screen capture substitutes for that.
Now the failure modes, because they are real. A capture layer sees everything: password managers, banking tabs, personal messages, customer data. A limitations-first Medium review of Screenpipe from May 2026 rightly calls 24/7 capture "a serious workflow decision" that demands operator discipline, local-first architecture or not. Recording other people, especially through a pendant, carries consent obligations that vary by jurisdiction and, more importantly, by relationship — I would not wear one into a board meeting without saying so. And Kahneman supplies the deepest caveat himself: a searchable archive is availability on tap, not judgment. If you never review it, both tools are expensive diaries nobody reads.
What I actually do is treat the archive as fuel for System 2. Twenty minutes every Friday, I query the week: what did I commit to, which decision did I defer twice, what exactly did I tell the client about pricing. The tool answers with a record; the peak-end machine in my head answers with a story. The gap between those two answers is the most useful coaching data I collect on myself all week — and it is the only reason I keep the recorder running.
