Switching from Readwise or Raindrop to Pith: bring your highlights, pay only for AI

Nobody wants to start over when switching tools. The importer brings links, folders, tags, dates and, above all, highlights. Saving is free; you pay only for what the AI does for you — and you decide at import which articles get it.

In short

Pith imports exports from Readwise Reader, Readwise (highlights CSV) and Raindrop.io. Links, titles, tags and the original dates come along; Raindrop folders can become collections; highlights are imported as real highlights and anchored to the right passage once the article text arrives. Readwise highlights find their article by title. All links are saved free; AI enrichment costs 2 cents per article, and you choose at import which articles get it.

Switching from Readwise or Raindrop to Pith: bring your highlights, pay only for AI

Switching tools rarely fails on features. It fails on the past: years of saved links, carefully sorted folders and, above all, the passages you highlighted. If switching meant starting over, most people would rather stay.

So Pith's importer brings exactly that along. And because Pith charges per AI action instead of a subscription, the move itself costs nothing.

What comes along

From Raindrop.io (Settings → Backups → Export → CSV):

  • all links with title, description, tags and original date,
  • folders: come along as tags and, if you want, also as collections — preselected for Raindrop,
  • highlights with notes as real highlights in Pith, anchored to the right passage once Pith has fetched the article text.

You need the CSV export for the highlights.

From Readwise Reader (Settings → Export → Export library):

  • the library with links, titles, tags and dates.

From Readwise (readwise.io → Export → CSV):

  • the highlights with notes. This export has no links, so highlights find their article by title — import the Reader library first, then the highlights. Anything that cannot be matched is listed with the reason instead of being dropped silently.

Links already in Pith are skipped and duplicates within the file are detected. A second import creates nothing twice. Exports from Pocket, Instapaper and the bookmarks of Chrome, Firefox and Safari work too.

Saving is free, AI for what you choose

All links are saved free: link, title, tags. The AI work — fetching the text, summarising, recognising entities, finding a place in the wiki — costs 2 cents per article. At import you decide what for:

  • the newest N articles, say the last 50,
  • or specific folders or tags, such as only "Clients" and "Regulation",
  • or none — everything is saved and searchable, and you process single articles later.

The importer shows how many articles that is and what it costs before you start. If you bring 2,000 old bookmarks, you don't pay 2,000 times — only for what you actually want in the wiki. Every per-action price is on the pricing page.

What is different afterwards

Readwise and Raindrop are good at what they are built for. Readwise is strong at collecting highlights from many sources and resurfacing them for review; Reader is an excellent reader. Raindrop is a tidy bookmark manager with collections and, by now, its own AI assistant.

Pith starts somewhere else. The articles you choose become an LLM wiki in which every claim cites its source. Every morning Pith writes a sourced report from your feeds. And when you want to find a passage again, Pith shows every mention in one place — see Where did I read that?.

Your imported highlights are more than a memory: they sit on their passage, are searchable and, over MCP, available to your own AI assistant — see Reading memory for your AI.

How to start

  1. Download the export from Readwise Reader, Readwise or Raindrop (steps above).
  2. In Pith, upload the file under Settings → Import.
  3. Choose which articles get AI enrichment and, for Raindrop, whether folders become collections.
  4. Start the import — it keeps running in the background, even if you leave the page.

New accounts get a start credit with their first save, plus €1 free credit every month. That covers the first articles with AI.

FAQ

Do I lose my highlights when I switch?

No. From the Raindrop CSV, highlights with their notes become real highlights in Pith and are anchored to the passage once the article text has been fetched. The Readwise highlights CSV contains no links, so its highlights find their article by title — import the Reader library first. Anything that cannot be matched is listed with the reason.

Does a second import create duplicates?

No. Links already in Pith are skipped, duplicates within the file are detected, and re-importing never duplicates highlights or collection entries.

What does the move cost?

Saving costs nothing: all links come into Pith with title and tags for free. If an article should also get its text, a summary and a place in the wiki, that costs 2 cents per article. At import you pick the newest N or specific folders; everything else can be processed later, one by one.

Do I have to cancel Readwise or Raindrop?

No. You can use both side by side — say, Readwise for reviewing highlights and Pith for the report and the wiki. The import works from an export; nothing changes in the other service.
