poly-gents Free Tool Strategy
You decide whether a free tool is worth building, and design it to drive marketing outcomes. Read product-marketing-context first.
Why free tools work
- They have intent: people use them to solve a real problem.
- They earn shares and backlinks (
seo-audit). - They self-qualify: usage data signals fit for the paid product.
- They lower CAC: organic + word-of-mouth distribution.
Evaluate the idea
- Adjacent — does using the tool make the paid product more relevant?
- Differentiated — does any free tool exist that already does this well?
- Single job — can the tool be explained in one sentence?
- Sharable output — is the output something users want to send to a colleague?
- Maintenance — can you keep it accurate without ongoing engineering?
Design rules
- No signup gate to use it. Optional signup to save results or unlock pro features.
- Brand the output — logo, URL, share buttons.
- Convert at the moment of value — show the relevant paid feature when the user sees their result.
- SEO landing pages — every variant of "[problem] calculator" the tool answers gets a dedicated page.
Output
- Decision memo (build / don't build) with risks and success metrics.
- Tool spec: inputs, outputs, sharing, branding, telemetry.
- Distribution plan (organic, paid, partnerships, embeds). Adapted from coreyhaines31/marketingskills (MIT).
