RemNote Tour with Founder Martin Schneider - Memory's Role in Knowledge Management

TL;DR

REM Note is positioned as a “tool for thought,” built to support varied workflows rather than a single study method.

Briefing

REM Note founder Martin Schneider traces the product’s design to a personal problem: as a computer science undergraduate, he poured effort into classes only to watch the material vanish by the next semester. That frustration pushed him to explore spaced repetition, but it also exposed a second need—capturing and organizing thoughts in a way that supports ongoing reasoning rather than one-off studying. REM Note is built around that “tool for thought” framing, aiming to support multiple workflows while staying easy to onboard.

Schneider credits user feedback for shaping the system’s breadth. He describes regular calls with people who use REM Note in very different roles—CRM, daily journaling, and classroom study—then translates those conversations into design changes that keep the tool general enough for varied thinking styles while still being precise in how it supports them. He also points to a feedback loop that users can feel: after calls, changes are made and communicated, reinforcing that the software evolves around real workflows rather than assumptions.

Spaced repetition plays a central but not exclusive role in his own knowledge practice. Schneider’s approach is less about memorizing facts for exams and more about making key ideas available “in the right context” so they can be queried quickly with low friction. He demonstrates this with a document built from reading and reworking research—using a one-sentence sketch plus detailed sub-questions for a concept like AlphaZero. In his workflow, bullets marked for spaced repetition automatically generate flashcards. Practicing those cards does two things: it internalizes the work he already wrote down, and it forces further reformulation after early rounds, when new connections appear or when his understanding tightens.

He also addresses a common worry: that flashcards might lock thinking into rigid phrasing. His answer is that creativity and synthesis don’t require the same “precision” as recall. When brainstorming, he can riff on internalized details (for example, pulling the “two-head” structure from AlphaZero) while keeping the lower-level facts accessible. Over longer intervals, he suggests the system can help ideas become fuzzier when they’re no longer worth maintaining in a specific form—sometimes prompting him to replace a narrow card with a more general principle.

Beyond flashcards, Schneider uses REM Note’s linked references and evergreen notes to support synthesis. Linked references help “spark” connections by bringing multiple related ideas into view, while evergreen notes act as durable claims that can later be refined and, when appropriate, converted into spaced repetition cards. He argues that the best knowledge workflow blends both: the tool can offload memory-heavy tasks that exceed human capacity, while the human mind still performs higher-level synthesis—such as recognizing analogies between ideas that were learned through different paths.

In the product roadmap, Schneider emphasizes making spaced repetition easier to use and less stressful, expanding the tool’s “semantic graph” capabilities, and enabling more ways to combine knowledge bases—especially when ideas are represented as concepts. He positions REM Note as a platform for intentional memory and thinking, with a long-term hope that schools and learners can shift from passive forgetting to deliberate, durable understanding.

Cornell Notes

Martin Schneider built REM Note after experiencing a common learning failure: he studied hard in classes but forgot the material soon after. The system is designed as a “tool for thought,” supporting multiple workflows, from classroom learning to CRM and journaling, shaped through direct user feedback. In his own practice, spaced repetition is used to internalize concepts so they can be recalled quickly in the right context—turning notes into flashcards via marked bullets. He uses practice not only to preserve details, but to refine them: early rounds often trigger tighter reformulation, while longer intervals can lead him to generalize or drop overly specific formulations. He pairs flashcards with linked references and evergreen notes so synthesis can emerge from both internal recall and structured browsing.

What problem drove Martin Schneider to start building REM Note, and how did that shape the product’s philosophy?

He describes a frustration from his undergraduate computer science period: he invested effort in classes to internalize material, only to forget it by the next semester. That pushed him toward spaced repetition, but it also highlighted a broader need—capturing and organizing thoughts in a way that supports reasoning over time. The result is REM Note’s “tool for thought” framing: it aims to support a wide range of thinking workflows, not just studying for tests.

How do spaced repetition cards get created inside his knowledge workflow, and what does he practice for?

He writes documents that break down concepts into a one-sentence sketch plus detailed sub-questions. Wherever he marks bullets with a spaced repetition trigger (shown as “double colons” in his example), REM Note automatically generates flashcards. The cards then prompt him with canonical recall questions—e.g., when he sees “AlphaZero,” he wants to immediately connect it to “self play” and reinforcement learning details, including how the system’s components (like the two-headed neural network) are used.

What does spaced repetition do for him beyond “remembering,” and how does it change his understanding over time?

He says practice helps internalize the work he already wrote down so he can draw on it later, but it also improves the notes themselves. After a few rounds, he often reformulates again: a card may surface a new connection, reveal a mismatch, or lead him to add or tighten questions. In some cases, longer spacing intervals make him treat the specific formulation as less worth maintaining, so he replaces it with a more general principle.

How does he connect internalized recall to creativity and synthesis without getting stuck in rigid phrasing?

He distinguishes precision for recall from flexibility for brainstorming. When brainstorming in REM Note, he can riff on internalized details (like the “two-head” structure from AlphaZero) while still generating new ideas. He also suggests that if a specific card stops matching his current understanding, the system can prompt him to generalize or stop practicing that narrow instantiation.

What roles do linked references and evergreen notes play compared with spaced repetition?

Linked references help spark synthesis by surfacing related ideas through browsing and hyperlink navigation—useful for gathering multiple pieces of context at once. Evergreen notes act as durable claims or hypotheses that can be refined; Schneider sometimes uses spaced repetition inside evergreen notes when a hypothesis needs repeated attention. Together, they support both “sparked” short-term exploration and durable internal recall.

How does he describe the division of labor between human thinking and the tool?

He argues that synthesis requires multiple ideas to come together in the right mental context. Linked references are one way to assemble that context, while internalized cards reduce the need to search as much. He believes some work can be offloaded to the computer (especially memory-heavy tasks), but higher-level synthesis—like noticing that two differently learned ideas represent the same underlying concept—still depends heavily on human judgment, though future automation could help.

Review Questions

In Schneider’s workflow, what triggers the creation of spaced repetition flashcards, and what kind of questions do those cards aim to answer?
How does he reconcile spaced repetition with creativity—what changes when he moves from recall to brainstorming?
Why does he think a “blend” of internalized recall (cards) and external browsing (linked references) is more effective than relying on only one?

5
Linked references and evergreen notes support synthesis by surfacing related ideas and maintaining durable claims, while spaced repetition strengthens internal access to key concepts.
6
Schneider argues that effective knowledge work blends human synthesis with tool-assisted memory management, since some tasks exceed human capacity.
7
The roadmap emphasizes easier spaced repetition workflows, deeper “semantic graph” capabilities, and better ways to combine knowledge bases across concepts and people.

Highlights

Schneider uses spaced repetition to internalize the “canonical way” to think about a concept—so recall becomes contextual and immediately useful for reasoning.

He treats flashcards as a reformulation engine: after a few practice rounds, his understanding often tightens or shifts, and some specific cards get replaced by more general principles.

Linked references “spark” connections through browsing, while internalized cards reduce the need to search—together they support both exploration and grounded synthesis.

He frames the tool as a semantic graph for knowledge, aiming to offload memory constraints while leaving higher-level analogy and synthesis to the human mind (with future automation possible).
