Strong fit. Contact data, sequences and call recording in one place, so research and outreach do not live in separate tools.

Watch out: Contact data is never as accurate as the counter suggests, and the AI writes on top of whatever it found. Every plan is metered in credits, so what you pay tracks how much you export rather than how many people log in.

Strong fit. A spreadsheet where each row can call data providers and models, which makes research that used to take a week into an afternoon.

Watch out: Credits, not seats, so the bill tracks how much you run rather than how many people use it. The paid rates are starting points that the action and data-credit selectors push upward.

Custom
adds unlimited search and imports, single sign-on, role-based access control and a dedicated growth strategist. Both paid tiers carry action and data-credit selectors that raise the price above the starting rate, so those figures are floors rather than fixed prices

Built for this. Connects thousands of apps and now runs agents across them. The integration count is the moat — an agent is only as useful as what it can touch.

Strong fit. Marketing, CRM and content in one place, with the AI reaching across all three because they share the same contact record.

Marketing Hub Starter plan −30%
Watch out: The free tier is the on-ramp and the jump to Marketing Hub is steep. Starter looks cheap because a limited-time offer is running against a $20 a seat list price, and every tier climbs with the marketing contacts and core seats you add.

Watch out: 99 a Fin outcome on top of every seat, so cost scales with volume rather than headcount. The entry price advertised is a new-customer offer against a $29 to $39 seat, and Fin can be bought on its own with no seats if you already run a helpdesk.

Two things separate these and both are on every card.
Fit
Whether a tool is built for this job, a strong fit for it, or
able to do it without that being its focus.
Free plan
Whether there is a tier you can keep using rather than a
trial that expires.
The order
Fit first, then a free plan, then alphabetical. There is
no score, no weighting we decline to publish, and nothing on this site a company can buy.
Questions
What is the best ai for lead generation?
There is no single answer, which is why this page lists 8 rather than one: Apollo, Clay, Copy.ai, Perplexity, ChatGPT, Zapier, Intercom, HubSpot. 2 of them are built for this kind of work rather than able to do it. Start with a free one.
Which of these have a free plan?
7 of the 8: Apollo, Clay, Copy.ai, Perplexity, ChatGPT, Zapier, HubSpot. Free means a real free tier you can keep using, not a trial that expires.
How was this list chosen?
By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
