Auto-Tagging library or incoming feeds

You can now create elaborate rules on how to tag content you save or that enters your feeds with keywords and AI prompts.

This means:

  • Less need for manually tagging stuff with high level of control and precision

  • A system for sorting incoming feed posts from your favourite Youtube channels, blogs, Substacks and Subreddits for the gems that really matter to you

    (feed support is functional but in pre-release state and can be toggled on in the settings > feature flags for beta users (reach out in the help chat to get upgraded). Appreciate any bug reports via the help chat)

Features

Auto-tagging by keywords, content type, [free]

Use keyword matching to auto-tag items.

Pricing: Free

Auto-tagging with LLM query [Pay as you go credits]

You can define custom prompts to take actions on a piece of content.

E.g. “Anything that talks about nuclear energy (e.g. new reactor designs, policy, economics, risks)”

Pricing:

  • Summary level: 1 credit per 500 total prompt characters (across all prompts) per piece of content

    • E.g. saving 100 pieces of content with a total of 1000 prompt characters: 200 credits

  • Deep level, full content analysis: Additional 1 credit per 1000 tokens of content (about 4000 characters)

    • E.g. saving or receiving 100 pieces with total of 4000 characters each and 1000 prompt characters: 200 + 200 = 400 credits

Backfill your library

When adding a new tag you can always choose to retroactively apply the tag to your your entire library. Anything already tagged with the tag will be skipped.

Others will be fully available in a few day when I polished them up. (If you find bugs, please report via the help chat, i am actively hunting for them and fixing them up right away)
