How we picked
Every one of these AI writing tools is scored by the same 7 criteria (scorecard v1). Each criterion gives 0 to 100 from the vendor's published data; the total is the weighted average. A criterion without verified data is left out and the other weights are re-normalised. A tool with under 60% of the weight covered is listed as not ranked, and so is a tool with no verified price and fewer than 2 verified features (“needs a verified price”); each score shows how many criteria it is based on. The core criteria are the same in every category; the category criteria are specific to AI writing tools. Nobody gets custom weights, including our own products.
| Criterion | Weight | Type | What we measure |
|---|---|---|---|
| Entry price | 25% | Core | Price per month of the cheapest paid plan, against the prices of other AI writing tools on the same billing basis (monthly-billed prices against monthly, annual-billed against annual).Log scale. Billed monthly: $9.99/month or less = 100, $69 or more = 0. Only billed annually: $4.92/month or less = 100, $49 or more = 0. Only free plans = 100. Usage-priced and one-time plans are not scored. |
| Free plan or trial | 15% | Core | Whether you can use the tool before paying: a free plan, or failing that a free trial, as shown on the vendor's pricing page.Free plan = 100. No free plan but a free trial = 60. The pricing page lists plans but shows neither = 0. No plans read = not scored. |
| Pricing transparency | 10% | Core | How much of the pricing is public: the share of plans with a published price ("contact sales" counts against), and whether there are at least 3 published tiers.80 x (plans with a public price / plans listed) + 20 x (public plans, up to 3) / 3. No plans read = not scored. |
| Verified features | 15% | Core | How many of the 8 features we track for this category the vendor's own pages verifiably show (analytics, team access, templates, ai assistant, brand voice, seo optimisation, plagiarism checker, browser extension). This counts verified features only: a tool that documents less scores lower here, and only here.Linear: verified features / 4 (half the tracked list) x 100, capped at 100. No tracked feature verified = not scored. |
| API, integrations and export | 10% | Core | Whether a public API exists, how many integrations the vendor states, and whether the vendor documents a way to export your data.Average of the parts with data: public API yes = 100, no = 0; integrations on a log scale (100 or more = 100); a documented data export = 100. None verified = not scored. |
| Cost per user (team of 3) | 15% | Category | Monthly price per user for a team of 3, on the cheapest paid plan that is priced per seat or states room for at least 3 users.Log scale: $13 per user or less = 100, $69 or more = 0. Plans that do not state a user limit are not used. No such plan = not scored. |
| Languages | 10% | Category | Number of languages the vendor says it offers.Linear scale: 100 or more = 100. No stated count = not scored. |
