Can AI replace Glasp?
Glasp's solo core is compact: build a private web highlighting workspace that imports user-supplied URLs or files, extracts metadata, supports notes, and searches the local corpus. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on data, import reliability.

Hidden costs: taxes may be added; paid purchases are generally non-refundable; private/advanced AI usage is metered by separate monthly caps
02Could AI build it for you?
The core job: Build a private web highlighting workspace that imports user-supplied URLs or files, extracts metadata, supports notes, and searches the local corpus.
What a working version needs:
- Node.js 22
- browser automation for user-authorized imports
- optional OpenAI API key stored in .env
Strong page because Glasp separates a compact personal workflow from the value of long-term polish.
03What you'd give up
- team libraries and institutional access
- licensed scholarly metadata
- publisher-specific import reliability
- citation graph scale
Glasp: Researchers pay for correct metadata, resilient importers, citation coverage, and workflows that survive publisher and browser changes.
04Free and cheaper alternatives
Highlights and margin notes on the live web; discovery is somebody else's problem.

Paste this into an AI coding tool (such as Claude, ChatGPT, Lovable or Replit) to build your own version.
Build a usable personal replacement for the core loop of Glasp. Use exactly this stack: Next.js 15 + TypeScript + SQLite + Playwright. Primary job: Build a private web highlighting workspace that imports user-supplied URLs or files, extracts metadata, supports notes, and searches the local corpus. Start from an empty folder and create the complete working project. Make the default mode single-user and private. Store user data locally unless the core job requires the declared self-hosted database. Do not add analytics, telemetry, ads, or third-party accounts. Put every secret and external credential in .env and provide .env.example. Use realistic sample data that is clearly labelled and easy to delete. Implement the smallest polished interface that completes the core loop end to end. Include clear empty, loading, validation, success, and failure states. Add import and export so the user is not trapped in the app. Use accessible keyboard navigation, labels, focus states, and sensible contrast. Validate untrusted input and never log secrets or private file contents. Deliberately exclude these paid-product advantages: team libraries and institutional access; licensed scholarly metadata; publisher-specific import reliability. Do not fake integrations, network effects, proprietary data, model quality, compliance, or security claims. Where an external API is optional, keep the app useful without it and explain the degraded mode. Write focused unit tests for the data model and the most important workflow. Add one end-to-end smoke test that proves the core loop works. Create a README with setup, permissions, architecture, data location, backup, and limitations. Add scripts for install, development, test, build, and a production-style local run. Run the tests and build before finishing, then fix errors rather than merely describing them.
