To compare AI tool pricing reliably, read each vendor's own pricing page on the same day and record the same things for every tool: the cheapest paid plan, how it is billed, what it includes and its usage limits. Sai does that for the tools you name, puts everything in one table with a link and date for each row, and flags any pricing page it cannot load instead of guessing.
What an AI pricing comparison should capture
An AI tool pricing comparison lines up the plans of several AI products on the same terms: price, billing period, seat rules, included features and usage limits, each taken from the vendor's official pricing page with the date it was read.
The price alone is rarely the answer. Two plans at a similar monthly price can differ in what they limit: messages, requests, credits, images, seats or the models included. A useful table puts those limits next to the price, in the vendor's own words.
Why comparison articles go stale
- Plans change often. AI vendors add, rename and re-price plans frequently, so a comparison from a few months ago may describe plans that no longer exist.
- Billing toggles. Many pages show annual prices by default and monthly prices behind a toggle. Mixing the two makes one tool look cheaper than it is.
- Region and currency. Some pricing pages redirect to a local version of the page with local currency, so two people can see different prices for the same plan.
- Per seat or per account. Team plans are often priced per seat with a minimum number of seats; individual plans are not.
- Moved or broken links. Pricing URLs get reorganized. A link that worked last quarter can now return a 404 or land on a generic page, and a table filled in from memory will not show it.
What to record for every tool
- Source: the exact pricing URL you read, and the date.
- Free plan: whether one exists.
- Cheapest paid plan: name, price, currency, monthly or annual billing.
- Seats: per user or per account, and any minimum.
- Key features: three that matter for your use, such as the models included, integrations or admin controls.
- Limits: messages, requests, credits or images, quoted as the page words them.
- Gaps: anything shown only after signing in, or a page that did not load.
Ways to build the table, compared
| Option | Fresh | Sourced per row | Effort | Catches broken links |
|---|---|---|---|---|
| A comparison article or review site | Only as fresh as its last update | Rarely | None | No |
| Asking a chatbot from memory | As of its training data | No | None | No |
| Opening every page yourself | Yes | If you note it | An hour or more for 10 tools | Yes |
| A scraper script | Yes | Yes | Breaks when page layouts change | Yes |
| Sai | Yes, read on the day | Yes, URL and date per row | One prompt | Yes, flagged in the table |
How to compare AI tool pricing with Sai
- List the tools and their pricing pages. Use the vendor's own URL for each. If you are not sure of one, ask Sai to find the official page from the vendor's homepage, not from search results.
- Say what to record. Start from the checklist above. The full prompt is in the Start with a prompt tab.
- Say what to do with gaps. Tell Sai to mark broken links and sign-in walls rather than fill them in. That rule is what makes the table trustworthy.
- Approve the sheet. Sai asks before it creates a file in your Google Drive.
- Re-run it monthly. Ask for the same table again and a list of what changed.
Run it from the API
Send the comparison to POST /v1/agents/message. success_criteria asks Sai to check each rule and return evidence, and recordTrajectory keeps a screenshot of every page it read:
curl -s https://api.simular.ai/v1/agents/message \
-H "Authorization: Bearer $SAI_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"message": "From each official pricing page in {{pages}}, record the cheapest paid plan, billing period, three key features and usage limits. Mark any page that does not load as pricing page not found.",
"options": {
"inputs": { "pages": "https://claude.com/pricing, https://cursor.com/pricing, https://github.com/features/copilot/plans" },
"success_criteria": [
{ "id": "sourced", "check": "Every row has the URL that was read and the date", "returnEvidence": true },
{ "id": "no-guessing", "check": "Pages that did not load are marked, not filled in", "returnEvidence": true }
],
"recordTrajectory": true
},
"wait": false
}'Poll /turns for the result. The quick start covers keys and the first call.
Limitations
- It reads what the page shows. Prices behind a sign-in, a sales form or a checkout are marked as such; Sai does not sign up or start a purchase to see them.
- Region matters. The cloud computer sees the version of each page served to its location and currency. Ask for a specific region if that matters to you.
- A table is a snapshot. Prices can change the day after. Keep the date column and re-run before a decision.
- It does not pick for you. The table compares plans; which one fits depends on how your team will use it.
