Free plans are where most people start with an AI tool, and they are also where most of the confusion lives. A limit that was true last spring may be different today, and the review you just read may be quoting the old number.
While researching our guide to free AI tools for freelancers, we kept finding sources that disagreed with each other. Reports of Perplexity's daily free Pro-search cap ranged from three to five. Reports of Otter.ai's free per-meeting time limit also differed between sources. For Asana's free Personal plan, some sources gave one user limit and others gave a lower one for newer accounts. The tools were not lying. The pages were simply written at different times.
This guide shows you how to check a free plan yourself in about ten minutes, and how to avoid building your work on a limit that has already changed.
Why websites disagree about free plans
- Pages go stale. A review written months ago keeps ranking after the plan changes.
- Plans change by account age. A company may change limits for new sign-ups and leave older accounts alone, so two people see different numbers.
- Limits move with demand. Anthropic's help center says free Claude usage is session-based and the number of messages varies with demand. OpenAI says the default model and the limits for ChatGPT Free can change.
- Many limits have no single number. Several free plans describe limits in general terms rather than fixed figures.
The 8 limits to look for
- Usage: messages, prompts, tasks or minutes per day or month.
- Users or seats: how many people can share one free account.
- Features: views, templates, integrations or tools held back for paid plans.
- Model or quality: whether you get the same AI model as paying users.
- Length and size: maximum file size, document length or meeting length.
- Storage and history: how long your work is kept.
- Export: whether you can take your data out, and in what format.
- Terms: rules on commercial use and on how your content is handled.
The 10-minute check
- Open the tool's own pricing page. Find the plan comparison table and write down the free column. (3 minutes)
- Search the help center. Look for a page about free plan usage or limits. Help centers often hold details the pricing page leaves out. (2 minutes)
- Read the terms and privacy pages. Look for commercial-use rules and what happens to your content. (2 minutes)
- Note the date. Write down the day you checked and where. Take a screenshot if you plan to quote it. (1 minute)
- Test with a real task. Use the free plan on one small job and see whether a limit stops you. (2 minutes)
Then set a reminder to check again in a few months. If a page matters to you, the Internet Archive's Wayback Machine can show earlier versions of it, which helps you see whether a limit changed.
Which sources to trust first
- The tool's pricing page and help center.
- The tool's terms, privacy policy and official announcements.
- Independent reviews, used for context only and only if they show a date.
- Forum posts and social media, used as a hint to go and check the official page.
Spot a stale review by looking for a missing date, a number with no link to the source, and a claim that does not match the official page today.
Words that hide a limit
- "Unlimited": check for a fair-use policy or a rate limit behind it.
- "Fair use": the real limit is not shown. Look for the policy page.
- "Limited trial" or "limited access": there is a cap, and it may be small. Notion lists its AI as a limited trial on the Free plan.
- "Varies with demand" or "subject to change": the number can move without notice.
A free plan tracker you can copy
Copy this into a spreadsheet and fill in one row per limit. It takes a few minutes per tool and stops you quoting a number you cannot source.
| Tool | Limit type | Number on official page | Source link and date checked |
|---|---|---|---|
| Example tool | Monthly usage | Number shown on the pricing page | https://... (official page) |
| Users or seats | |||
| Features or views | |||
| Data and commercial-use terms |
What to do when a limit changes
- Keep your own copies. Export your work regularly so a plan change never traps it.
- Do not rely on one tool. Keep a second option you have already tried for anything client-critical.
- Upgrade only for the limit that hurts. If one limit blocks paid work more than once, pay for the plan that removes it.
- Tell clients. If a change affects a deliverable, say so early.
