Competitor research with free AI marketing tools

What to take away

A marketing manager in Leeds keeps three competitor tabs open: two pricing pages and a launch post. None of them records when it was last true. This checklist uses free AI marketing tools and public records to close that gap.

Fix the competitor list at four to six named companies before you open any tool.
Collect dated documentspricing pages, tender responses, job adverts, help-centre articles.
Record the source and the date beside every claim you decide to keep.
Check consent and ethics in the same pass, not in a later review.
Stop when each competitor has a one-page brief a campaign team can act on.

Set the competitor list before you open any tool

Competitor research drifts when the list changes every week. Decide the set, write it down, and treat any addition as a formal change. The gap matters most when a rival cuts a price.

Lock the competitor list

Name four to six rivals
Include one different company size
Add one non-obvious alternative
Note buyer and budget sign-off
Agree file owner and refresh rate

Name four to six rivals, including one that sells to a different company size than yours.
Add one non-obvious alternative, such as an agency, a services firm, or an internal build.
Note the buyer each rival targets and the job title that signs off the budget.
Agree who owns the file and how often it is refreshed.

An example set for a UK marketing-software seller: HubSpot, Mailchimp, Klaviyo, Brevo and ActiveCampaign, plus one agency that bids for the same campaign budget. Substitute the rivals your own buyers shortlist.

The audience research methods behind these briefs map the competitor set to segments you can serve.

Collect dated primary evidence

A dated primary document settles an argument months later; a vendor summary does not.

Vendor summary vs dated evidence

Vendor summary

Source: Vendor
Date: Often absent
Settles disputes: No
Confidence: Unclear

Dated evidence

Source: Primary document
Date: Saved on visit
Settles disputes: Yes, months later
Confidence: Verified, inferred, unconfirmed

Where to look first

The competitor's own plans or pricing page, saved with the date you visited it.
Contracts Finder, where public sector contracts in England are published, sometimes with full responses.
Companies House filings, which give accounts, directors, and confirmation statements.
Job adverts, which show which teams the rival is funding this quarter.
Help-centre pages and changelogs, which date feature claims precisely.

AI helps with the workflow: a free assistant such as ChatGPT, Google Gemini, or Microsoft Copilot summarises long help-centre pages. A free page-change watcher such as Visualping or ChangeDetection.io diffs pricing pages. Manual collection still supplies the source URL, the visit date, and the confidence label.

What to write down

The claim in one sentence, quoted where the wording matters.
The source, plus the date it was published or last updated.
The audience the claim is aimed at, in your own words.
A confidence labelverified, inferred, or unconfirmed.

Keep the brief as a Markdown file with these fields: competitor, claim, source URL, date, audience, confidence label.

Policy changes decide what rivals can promise. Digital markets policy that shapes what marketing software providers can offer sits with the Department for Business and Trade and the Department for Science, Innovation and Technology, whose public announcements are worth watching.

Free AI marketing tools for competitor research

Four free assistants cover most of the reading: ChatGPT, Google Gemini, Microsoft Copilot and Perplexity. All four have a free tier, and each is strong enough for the work here: summarising a pricing page, diffing two versions of a help-centre article, or turning a tender response into a five-line brief.

"Summarise this pricing page in five bullets, quoting every price tier exactly as written."
"Compare these two job adverts and list the teams each competitor is hiring for, with the job titles."
"Read this tender response and list every claim about delivery times, support and price."
"From this help-centre page, extract the product claims and the date the page was last updated, and mark anything you cannot confirm."

Free public sources fill the rest: Google Trends for search demand, the Meta Ad Library for competitor ads running now, and Google Alerts to catch a new pricing page the week it appears.

Those routes replace the paid competitor-data subscriptions this workflow exists to avoid: Semrush, Ahrefs and Similarweb, which sell monthly plans for keyword, traffic and ad data. The free routes are thinner, but they cover a first cycle; a paid seat earns its place only when manual checks cannot keep up.

Keep consent and ethics checks in the same file

Research that later feeds email or messaging has to meet the same standards as the campaign. The ICO sets out the direct marketing rules under PECR for electronic communications, including consent and the soft opt-in.

Ethics sit alongside the law. The DMA code gives data-driven marketing a set of standards you can test a rival's claims against.

Does the claim rest on data the customer agreed to give?
Would you defend the same tactic in a complaint?
Is it sourced, or is it a marketing line?

Once the evidence is scored, decide the target audience in England you will address, because a competitor list means little without a segment behind it.

Worked example: a four-week cycle on a fixed budget

The figures below are illustrative, not quoted rates, and assume a day rate of £300.

Week	Task	Illustrative cost
1	Fix the competitor list and name an owner	£0
2	Pull dated documents for every rival	£600
3	Draft one-page briefs and score each claim	£300
4	Review with sales and legal, then publish	£300

That is £1,200 for one cycle. A team already paying £400 a month for a competitor tracking tool should still ask which primary document that subscription replaces. Expect one cycle per quarter, not per month.

Common questions

How many competitors should the research cover?

Four to six is enough for a first pass. Go beyond that and the briefs stop being read. Add a seventh only when a named buyer asks.

Can we do this without paid tools?

Yes, for a first cycle. Public documents cover pricing, features and hiring. Paid monitoring earns its place when manual checks cannot keep up.

Does PECR apply to competitor research?

No. PECR governs how you contact people. It applies once research informs an email or messaging campaign, not when you read a public pricing page.

How do we keep the file current?

Give every page a refresh date and re-check it quarterly. Anything older than two quarters is marked unverified until someone re-reads the source.
