I made an open source Windows app to rewind and search everything on screen

Cross-platform alternatives and related tools

  • Many ask for Linux and macOS support; several similar tools are mentioned: Memento (Linux, with LLM), ActivityWatch, TimeSnapper, ManicTime, rem/xrem (macOS, Rust cross‑platform), Rewind/Limitless, ScreenMemory, Apse, Atlas Recall, and unlost.
  • Some prefer browser‑only or history‑centric tools; extensions like SingleFile and BetterHistory or an “archiving proxy” are seen as lighter‑weight approaches.

Use cases and value

  • Frequent use cases: recalling what was done yesterday for standups/retros, reconstructing debugging sessions, finding forgotten webpages, proving time spent for consulting/audits, and general memory aid (especially for ADHD or heavy multitaskers).
  • Long‑term users of similar products report years of continuous capture (every few seconds), calling it invaluable for disputes and data recovery.

Technical approaches: video vs. metadata vs. accessibility APIs

  • Discussion on avoiding raw video by recording window metadata (titles, positions) or using accessibility APIs; some tools do that, but app inconsistency makes OCR simpler in practice.
  • Ideas to combine local LLMs, vector search, and knowledge graphs over screenshots or captured text.
  • Storage estimates like ~100–200 GB/year are seen as acceptable by some, high by others; proposals include lower resolution, grayscale, and AI upscaling.

Installation, UX, and tooling concerns

  • Criticism of instructions suggesting copying ffmpeg into C:\Windows\System32; preference is to keep binaries in app folders or add to PATH.
  • Some users can’t access the Notion page due to aggressive JS requirements and blockers; this is a barrier to adoption.

Privacy, surveillance, and misuse

  • Strong concern that this is “visual keylogging” and ideal spyware, especially in corporate or nation‑state contexts.
  • Others counter that any software can be spyware; open source and local‑only design plus blocking network access mitigate risk.
  • Several note enterprise potential for employee monitoring, but others argue screen recording is less likely than simpler telemetry (logins, keystrokes).

Future directions and related concepts

  • Comparisons to Black Mirror’s “The Entire History of You,” AR smart glasses, and wearable recorders; some see this as dangerous, others as a powerful memory prosthesis.
  • Academic prior art cited (e.g., DejaView, process checkpointing/CRIU, NILFS, “cryofreeze”‑style systems) showing similar ideas explored decades ago.
