AI Tool Comparison
Grammarly vs Longshot AI
A side-by-side breakdown to help you pick the right tool for your workflow.
Grammarly
Catch grammar and clarity issues as you write, then let built-in AI agents draft, rewrite, and complete tasks across your apps. Grammarly's parent company rebranded to Superhuman in October 2025.
Longshot AI
Was a fact-checked, cited long-form SEO content generator. LongShot AI discontinued its core product on June 30, 2025 after 4+ years and 200,000 users; the team now offers AI agent/GTM automation under a new brand.
Bottom Line
Last reviewed: August 2026
Longshot AI is no longer an active product (discontinued: shut down June 2025), which settles this comparison in Grammarly's favor before you weigh anything else below. Grammarly and Longshot AI both compete in Writing, overlapping most directly on writing. Grammarly runs on a freemium model while Longshot AI runs on a paid-only plan, which alone may settle it if budget or a free tier is a hard requirement. Grammarly carries the higher rating (4.7 vs 4.3), but a gap that size rarely overrides a real workflow fit on its own.
Choose Grammarly if…
Best for catching grammar and clarity issues in real time as you write anywhere online, and its edge is built-in AI agents now draft and rewrite across your apps, not just proofread. The baseline writing check most people should already have running. Lean toward Longshot AI instead if was known for FactGPT, a fact-checking layer that verified article claims against live sources before publishing matters more for your use case.

Lean toward Grammarly instead if built-in AI agents now draft and rewrite across your apps, not just proofread matters more for your use case.
