How we picked
Every one of these caption and hashtag 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 caption and hashtag 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 caption and hashtag tools on the same billing basis (monthly-billed prices against monthly, annual-billed against annual).Log scale. Billed monthly: $8.08/month or less = 100, $32.31 or more = 0. Only billed annually: $5/month or less = 100, $59 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 6 features we track for this category the vendor's own pages verifiably show (analytics, team access, templates, ai assistant, hashtag research, caption generator). This counts verified features only: a tool that documents less scores lower here, and only here.Linear: verified features / 3 (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. |
| Platform coverage | 15% | Category | How many of the 15 social platforms we track the vendor says the tool supports.Linear: platforms / 10 x 100, capped at 100. No verified platform list = not scored. |
| Cost per connected account | 10% | Category | Monthly price per connected account on the cheapest paid plan that allows at least 3 social accounts.Log scale: $2 per account or less = 100, $40 or more = 0. Plans that do not state an account limit are not used. |
