Our picks

  1. 01 Product and API docs for developer teams

    GitBook

    GitBook Free is useful for an individual maintaining product docs with Git sync and an API playground. A branded public docs site moves to Premium, where the site fee and additional collaborator fees both matter. Teams should price the exact editor count before comparing it with flat-rate knowledge bases.

    What it costs
    One Premium docs site with two additional paid users would cost US$89 per month equivalent, or US$1,068 yearly, before tax.

  2. 02 Branded multilingual knowledge base

    Helpjuice

    Helpjuice targets organisations that want a managed knowledge base with custom design and collaboration. Its entry plan lists 30 users, but the public price text omits a currency symbol; buyers should confirm the billed amount and currency before committing.

    What it costs
    For a 25-person support organisation, the published 30-user entry allowance appears sufficient. The site displays 249 per month (2,988 over 12 months in that billing currency), but the payable amount must be confirmed with sales.

  3. 03 Docs-as-code for API-first products

    Mintlify

    Mintlify makes most sense for a developer-facing product whose documentation needs to evolve with its API. Its free publishing foundation is useful, but upgrading should be justified by the assistant, automation and governance workflow rather than appearance alone.

    What it costs
    At the displayed $450 monthly rate, one Pro project costs $450 × 12 = $5,400 per year before tax. Illustratively, 200 assistant answers × 25 credits plus 12 documentation updates × 250 credits use 8,000 credits, within 10,000 included credits. No narration or other projects are assumed.
    Skip it if
    You only need a basic internal wiki, cannot maintain API specifications, or require enterprise authentication and hosting controls on a low-cost self-service plan

  4. 04 Summarising research papers for review

    Scholarcy

    Scholarcy fits readers who need to screen papers consistently and revisit the findings later. The saved flashcard library and literature-matrix export are more compelling than a one-off summary alone. It should support reading rather than replace critical appraisal, and the paid price needs direct confirmation before purchase.

    What it costs
    A student who only needs an occasional article can use the stated free summarizer at US$0. A department with 20 readers should request multi-user licensing; no paid budget is fabricated from the unverified individual price. Confirm whether the quote is annual, per user or institution-wide.
