GrantGunner - 2026 Pricing, Features, Reviews & Alternatives

GrantGunner is a cloud-based AI grant discovery and application platform serving startups, charities, research institutions, and social enterprises. An AI agent continuously scouts funding opportunities matched to an organisation's sector, stage, and geography, surfacing grants, fellowships, competitions, accelerators, prizes, and investor programmes from multiple data sources around the clock. Chrome and Firefox browser extensions detect form fields on live funder portals, extract application questions in one click, draft answers drawn from the organisation's saved profile and past submissions, and load responses field by field directly into the funder's form. All discovery, drafting, and pipeline tracking is managed from a single interface.

GrantGunner operates in two modes switchable at any time: full autopilot, where the AI agent submits applications without per-submission approval, and assisted mode, where users review and approve each submission before it goes out. Application drafts are generated from the organisation's own materials, documents, and historical answers rather than generic output, preserving a consistent organisational voice across all submissions. An integrated opportunity calendar auto-adds new funding calls when they open, flags deadlines seven days in advance, marks applied grants to prevent duplicate submissions, and supports filtering by sector, funder, or award amount.

GrantGunner is particularly suited to organisations without a dedicated bid writer that require a structured, auditable funding pipeline. Pipeline tracking spans the full lifecycle from discovery through to award or feedback, giving grant-seeking teams visibility across every active opportunity. Eligible opportunities are presented with eligibility details laid out clearly, reducing time spent assessing unsuitable calls before committing to an application.
