Today, we're excited to announce Synopsis on ProductHunt, the newest API built on top of Saasify!


  • Uses state of the art AI to extract the core content of any webpage
  • Uses a variety of metrics to generate quality extractive text summaries
  • Summarizes html or text content
  • Utilizes html structure as a signal of text importance
  • Includes basic abstractive shortening of extracted sentences
  • Hosted by Saasify
  • Thoroughly tested and used in production


The following examples all use HTTPie, a more intuitive version of curl.

Replace /summarize with /detail to see the full metrics for how the input was processed which will give you a better understanding of why certain sentences were deemed more important by the algorithm.

  • tfidf overlap for base relative sentence importance
  • html node boosts for tags like <h1> and <strong>
  • listicle boosts for lists like 2) second item
  • penalty for poor readability or really long sentences

Here's an example of a sentence's internal structure after normalization, processing, and scoring:

  "index": 8,
  "sentence": {
    "original": "4. For the cost of 1 highly produced video, you can get a year's worth of videos from Automagical.",
    "listItem": 4,
    "actual": "For the cost of 1 highly produced video, you can get a year's worth of videos from Automagical.",
    "normalized": "for the cost of 1 highly produced video you can get a years worth of videos from automagical",
    "tokenized": [
  "liScore": 1,
  "nodeScore": 0.7,
  "readabilityPenalty": 0,
  "tfidfScore": 0.8019447657605553,
  "score": 5.601944765760555
