Documents and notes decision
Readwise Reader
A minimal Readwise-like workflow (ingest highlights, search/tag, daily spaced-review email, and basic exports) is realistic for a competent developer to build and maintain; reproducing the full product (Reader app polish, many maintained connectors, and brand/scale) is not practical for a one-person effort.
Visit website↗Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Ingest highlights from reader sources, store and index them, surface a scheduled daily review email with spaced-repetition selection, allow search/tag/annotation, and export/sync highlights to other apps.
What it still won’t have
- Polish and UX of the official Reader app (mobile/web)
- Official native integrations and maintained connectors to many reading platforms
- Brand reputation and userbase-driven trust/support
- Early access to Readwise feature roadmap and locked-in pricing
What remains hard
- Brand trust
Readwise helps thousands of readers get the most out of their digital highlights.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a self-hosted highlights manager using Node.js (Express), Postgres, and a small React UI. In scope: (1) an import endpoint that accepts uploaded Kindle/Instapaper highlight exports and a simple OAuth-based connector stub; (2) store highlights and metadata in Postgres and add full-text search (Postgres tsvector); (3) a background worker (Bull/Redis) that picks highlights per a simple spaced-repetition schedule and sends a daily email via SendGrid; (4) a React web UI to browse, search, tag, and annotate highlights; (5) an export worker that writes to Notion via its API. Out of scope: mobile apps, large-scale connector coverage, proprietary Reader UI polish, and synchronization edge-cases. Include error handling for failed imports, retries for email and export jobs, authentication (magic links or simple account/password), and unit/integration tests for import, scheduling, email sending, and export flows.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
