Strengths and limits
Flint
Strengths
- Free pilot for a small group: The pricing page lists a free plan for up to 80 users, which covers a few classes.
- Teachers can see everything: Live sessions, transcripts, alerts and summaries are listed for teachers and administrators.
- Built on the teacher's own materials: Activities can draw on uploaded PDFs, slides and links, and the AI prioritises them, according to the FAQ.
Limits to plan around
- Sales-only above 80 users: Every paid tier says Contact sales; there is no self-serve checkout or published price for a single teacher.
- Free plan scope unclear: The page calls it free, the pilot FAQ calls it a free trial, and no time limit is stated.
- Free plan gets the faster model: Paid and trial schools get a more capable model than free-plan schools, according to the FAQ.
Perplexity
Strengths
- Traceable answers: Every answer links to the web pages it drew on, so each claim can be opened and checked.
- Useful Free plan: Basic search with citations is available without a subscription.
- Built-in research tools: Research mode, Spaces and scheduled Tasks cover reports, shared workspaces and recurring alerts.
Limits to plan around
- Source links still need checking: A link shows where a sentence came from; you still have to open the page and confirm the passage and its date.
- Free research is tight: The pricing page describes Free only as limited usage, and the plan comparison table allows a single Research query a month.
- Pro and Max limits are not published as numbers: Individual plans describe weekly and monthly limits for average or advanced use, so heavy users need to watch their account usage.

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.
