Plans and Capability Boundaries ​

Lens currently exposes academic capabilities through three membership tiers: Plus, Pro, and Max. Plan benefits apply only during the membership validity period. At task submission time, regular, advanced, or premium credits are still consumed according to the selected model and task type.

If your credits are insufficient, purchase a plan or top up credits before continuing.

Plus ​

Plus is suited for lightweight daily academic reading and writing.

Available capabilities:

  • Paper Summary
  • Arxiv Summary
  • Arxiv English Summary
  • Chinese Polishing
  • English Polishing
  • Chinese-English Translation
  • Mind Map Generation
  • Code Explanation
  • References to BibTeX

Not supported:

  • PDF Deep Reading
  • PDF Batch Summary
  • Word Batch Summary
  • advanced LaTeX tools
  • multi-step orchestration

Pro ​

Pro is suited for high-frequency paper reading, manuscript handling, and standard research workflows.

Pro includes everything in Plus, and additionally supports:

  • PDF Deep Reading
  • PDF Batch Summary
  • Word Batch Summary
  • LaTeX Summary
  • Precise LaTeX Translation
  • LaTeX English Polishing
  • LaTeX Chinese Polishing
  • LaTeX Highlighted Correction

Pro supports orchestration with up to 2 steps, for example:

text
PDF Deep Reading -> English Polishing

Max ​

Max is suited for heavy research, complex material processing, and full research chains.

Max includes everything in Pro and can use the full academic capability set currently exposed in Lens. Max supports orchestration with up to 3 steps, for example:

text
Paper Quick Read -> Chinese Polishing -> Mind Map

Billing and Validity ​

  • Monthly plans and monthly redemption codes issue the corresponding quota with a 30-day validity.
  • Annual plans and annual redemption codes issue 12 months of quota with a 365-day validity.
  • Regular, advanced, and premium credits correspond to different model or task consumption bands.
  • Actual deduction follows the selected model, task type, and what the product UI shows at submission time.
  • Once the membership expires, the plan-specific capabilities stop being active. Renew or redeem a new membership code to continue using those capabilities.

Task Execution Notes ​

  • Orchestration runs in series, so the next step starts only after the previous step completes.
  • PDF, Word, LaTeX, long papers, and slower upstream models increase the total runtime.
  • During long tasks, use the progress area in the message to inspect the current step, completed steps, and failure state.
  • If a capability is hidden or the UI asks for an upgrade, the current plan usually does not support that capability.

Safety Reminder ​

Before uploading a file, make sure you are allowed to process it. Do not upload keys, identity documents, contracts, customer material, unauthorized full papers, passwords, or other sensitive content.

AI output can be wrong, incomplete, or outdated. Verify important conclusions yourself before using them in research, experiments, citations, legal work, medical work, or finance.
