RepDB
Sapling sits on top of CRMs and messaging platforms to help agents more efficiently compose personalized responses through suggested responses, macros, autocomplete, and grammar and spell checking.
We also offer an API and SDK for businesses to integrate these capabilities into their own products.
Please contact us for custom models for specific industries and use cases.
RepDB is a one-time-purchase exercise dataset for developers building fitness and workout apps โ not a subscription, not a rate-limited API. You download the data once and own it: JSON (and SQLite on the higher tier), WebP images, and full EN/DE/ES translations, with no per-request billing and no dependency on our servers staying up.
A free tier includes 250 exercises with flat-style 512ร512 images, attribution-licensed for commercial in-app use. The Starter tier ($199) adds the full catalog in classic white-background style. Standard ($399) adds transparent 1024px images, looping animations, exercise relations (similar/progressions/regressions), workout templates, and embeddings โ exclusive to that tier.
Every exercise includes muscle-group highlighting, equipment/muscle icons, MET values, and safety/goal tags. Compared to GIF- or JPG-based competitor APIs, RepDB images are transparent WebP with no watermarks, so they drop into any app UI without a white box around them.
Sapling.ai RepDBSapling.ai's answer
Business teams -- startups as well as enterprises. Our API/SDK is designed for developers to integrate LMs quickly and without having to write guardrails and postprocessing logic.
RepDB's answer:
Solo developers and small teams building fitness or workout-tracking apps (iOS, Android, web) who need licensed exercise images and structured exercise data, but don't want to build their own media pipeline or depend on a rate-limited third-party API.
Sapling.ai's answer
Our team did research in machine learning and generative AI at Berkeley, Stanford, and Google before starting Sapling.ai.
RepDB's answer:
RepDB grew out of a consumer workout app its creator was building solo. Sourcing exercise images and data meant either paying for a subscription API with usage caps and no caching rights, or producing everything from scratch. The illustrated, multi-language dataset was built for us first, then split out as its own product once it became clear other indie developers had the same problem and preferred to buy the data outright rather than rent it through an API.

LLMs (language models), generative AI
Sapling.ai's answer
Built for enterprise, self-hosted/local option, multilingual, easy-to-use SDK
RepDB's answer:
RepDB is sold as a one-time download, not a metered API โ you own the JSON/SQLite data and WebP images outright, with no rate limits, no per-request billing, and no risk of the vendor cutting off access. It's also the only dataset in this space with EN/DE/ES translations, transparent (alpha-channel) images with no watermark, muscle-group highlighting, safety/goal tags, and looping animations on the higher tier.
Sapling.ai's answer
Data security options, hands-on support, enterprise team management and reporting
RepDB's answer:
Most alternatives are subscription APIs โ you pay monthly, you're capped on requests, and ExerciseDB's terms of use explicitly forbid caching or storing the data at all, so every image render is a live paid API call. RepDB is the opposite: pay once, download the files, self-host with zero ongoing dependency. It's also the only option offering true DE/ES localization and transparent images instead of a white box behind every exercise.

I was wondering about grammar checking tools in the era of LLMs, especially for grammar checks beyond English, and Sapling https://sapling.ai seemed decent. Nobody seems to have mentioned it here? - Source: Hacker News / about 1 year ago
