Pricing in detail
Where Spark wins
Free for personal use. Smart inbox prioritization. Cross-platform mobile app excellence. Gmail, Outlook, iCloud all supported.
Where Pranan wins
Voice matching. Spark's drafts use generic AI if they offer drafting at all. Pranan reads your sent mail and builds a fingerprint from your actual writing patterns. The drafts come out sounding like you wrote them.
Relationship intelligence. Pranan auto-classifies every contact into a tier (investor, client, partner, team, advisor) and adjusts the draft accordingly. Your investor email reads different from your engineer email, automatically.
Morning briefing. Pranan compiles overnight activity into a 30-second scan: what needs you, what's done, what's coming up. More on the morning briefing.
Free forever plan. 300 voice-matched drafts a month, no credit card. Spark is paid-only or has a more limited free tier.

Pick Spark if
- You want a free email client with smart features
- Cross-device mobile email matters
- You don't need voice-matched AI drafting
Frequently asked questions
Can Spark learn my writing style?
Not the way Pranan does. Pranan reads hundreds of your sent emails to build a writing fingerprint specific to you. More on how voice matching works.
Which is better for relationship-driven work?
Pranan's relationship intelligence layer is purpose-built for managing communication across investor, client, partner, and team tiers. Spark is built for a different problem.
Can I use both?
Yes if their workflows don't overlap. Many operators run a tool like Spark for its specialty alongside Pranan for voice-matched drafting.
