The short version

  • Only Mendeley has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mendeley free tier limited to 5 Reading Assistant questions per month and 2GB storage; TetraScience pricing is scoped on connected instruments and data engineering effort rather than a published unit, so the cost of adding a new laboratory or an acquired site is impossible to forecast without going back to the vendor.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mendeley

  • Free tier limited to 5 Reading Assistant questions per month and 2GB storage
  • Annual billing required to receive one free month equivalent discount
  • Storage limits restricted on Plus (5GB) and Pro (10GB) tiers

TetraScience

  • Pricing is scoped on connected instruments and data engineering effort rather than a published unit, so the cost of adding a new laboratory or an acquired site is impossible to forecast without going back to the vendor.
  • Value depends entirely on connector coverage for your actual instrument estate; an instrument type without an existing productised connector becomes a services engagement with its own timeline and cost.
  • The GxP package is a separate annual subscription rather than an included capability, so a company that starts in research and later needs regulated use faces an additional commercial line and a validation exercise.
  • It is infrastructure with no end-user application of its own, so the business case rests on downstream analytics and AI work that has to be resourced and delivered separately before anyone sees a benefit.
  • Deployment is a multi-year programme touching instruments, networks, validated systems and site IT, and organisations consistently underestimate the internal effort required from people who also have day jobs running the laboratory.

TetraScience: Does it replace my ELN or LIMS?

No. It sits underneath them, harmonising instrument data and making it available to whatever applications you already run.

Mendeley: What storage do different Mendeley plans include?

The free tier includes 2GB storage. Plus tier provides 5GB storage. Pro tier includes 10GB storage. Max tier offers unlimited storage across all your research libraries.

Source
TetraScience: Is it usable in a GxP environment?

Yes, with the separately subscribed Tetra GxP package. It reduces validation effort substantially but does not eliminate your validation obligation.

TetraScience: Can I get the harmonised data out?

Yes. Tetra Data is designed to be accessible to your own analytics tools rather than confined to the platform.
