How to choose

  1. Pick the job. Searching papers, polishing text and building proposals need different tools.
  2. Check what counts toward limits. Elicit counts reports, not searches. Grammarly counts AI prompts.
  3. Count your seats. Per-seat pricing grows fast for teams.
  4. Start with a free plan where one exists. Elicit, Grammarly, Rytr, Xtensio and Logically.app all have one.
  5. For finance, legal or audit work, expect a demo and a quote. Hebbia and DataSnipper don’t list prices.
