Side by side
Research vs. writing
Grantable's center of gravity is the draft: it writes from your past content and turns a funder's rules into a checklist. Grantlas's is the shortlist: foundations and open grants ranked against your organization, with the reason and red flags.
Bottom line: Pick the tool for your bottleneck.
Writing with Grantlas
We think drafting belongs in the assistant you already write in. Connect Grantlas to Claude or ChatGPT, included in every plan, and ask for the letter there: it pulls in your profile, the funder's giving by year and how to apply, and the grant's eligibility rules.
Bottom line: Research here, write where you already write.
After you apply
Grantlas tracks each application in your own stages, with tasks, dated notes and report due dates, reminders 60, 30, 14, 7 and 3 days out, a calendar feed and board reports showing win rate and money awarded.
Bottom line: Deadlines, tasks and reports in one Tracker.
Consultants
Grantlas Pro includes 3 client organizations for $199 a month, and $49 a month for each extra, up to 5. Each has its own profile and matches, with one Tracker across all of them and client status reports. Grantable's Agency Hub is $300 a month on top of a paid plan, so at least $350.
Bottom line: For up to 5 clients, Grantlas costs less.
