Strengths and limits
NanoGPT
Strengths
- No markup on list prices: The pricing page says text models cost the same per million tokens as at the provider.
- No monthly commitment: Pay as you go has no fee and deposits start at $1 by card.
- Local chat history by default: Web conversations stay on the device unless sync or sharing is switched on.
Limits to plan around
- Pro excludes the big commercial models: The $12 plan covers open-source models; GPT, Claude and Gemini are billed from the balance.
- Pro is personal only: The terms bar commercial use, resale and shared accounts on subscriptions.
- Retention depends on the route: Final logging depends on the selected provider, and stored file copies have no single maximum retention period.
Grammarly
Strengths
- Works where you already write: The same suggestions run in browser extensions, desktop apps, Office and Google Docs add-ins and mobile keyboards.
- Usable free tier: Free has no time limit and includes spelling, grammar, tone detection and a monthly prompt allowance.
- Flexible Pro billing: Pro can be paid monthly, quarterly or yearly per member, and a team account can grow to 149 seats.
Limits to plan around
- Refunds only where law requires: You can cancel at any time, but paid time is refunded only when local law requires it.
- Review agents are paid: Plagiarism Checker, AI Detector and Citation Finder need Pro, and Free gets a single AI Grader scan a day.
- Own rewrites can trip the detector: Text rewritten by Grammarly's agents is likely to be flagged by its AI Detector.

Comparing tools from different categories is fine, and often useful — a writing assistant and a research tool solve different halves of the same job. The table will show you exactly where they diverge.
Questions about comparing tools
How does the comparison work?
Add two tools to the comparison tray from any tool card, then open this page. The table pulls each tool's verified plan details, platforms, strengths and limits from its profile, so both columns carry the same kind of evidence, with a separate source-check date for each tool.
Do you declare a winner?
No. The table sets two tools against each other on documented facts, not on a score. Which one wins depends on your task, your budget and your usage volume — three things we cannot see from here.
Why are some cells empty or marked unverified?
Because we could not confirm that detail on the vendor's own pages. Rather than filling the gap with a figure from elsewhere, we mark it and say why on the tool's profile.
Can I compare more than two tools?
Not at once. Two columns keep the differences readable and force a real decision. Remove either selected tool to replace it, or clear both to start a new pair.
Every figure in the table above comes from the linked profile, where the source and the verification date are listed. Browse all tools or read the editorial policy.
