Haru is built for people who want workplace communication to sound clearer and more professional. It can refine emails, Slack drafts, and spoken updates in real time, turning rough language into more polished, executive-style wording. The website also provides a tone score and creates learning cards from the mistakes a user makes repeatedly.

How Haru works

Voice coaching: Users can speak freely and receive real-time transcription. Haru removes filler words and vague phrasing, then adjusts the language to fit the audience and situation.
Text refinement: Paste an email, Slack draft, or proposal to receive a rewritten version, grammar corrections, a tone score, and a one-line explanation of how the recipient may interpret it.
Learning engine: Each session records recurring problems and turns real weak sentences into spaced-repetition flashcards, helping users work on their communication blind spots over time.

What the rewriting looks like

The website illustrates the approach with a team update. The original message says, “Hey guys, so I basically finished the thing we were talking about but there were some issues and we kind of ran out of time so I guess I'll need more time to finish it properly.” Haru rewrites it as: “I've completed the core implementation and identified two edge-case issues that require an additional day to resolve correctly. I'll deliver the final version by Thursday EOD.”

The revision removes filler phrases such as “basically” and “kind of,” replaces the vague reference to “some issues” with two specific edge-case issues, and turns “I guess” into a commitment with a clear deadline.

Pricing

Haru uses one-time credit packs rather than a subscription or automatic recurring charges. The free plan includes 15 credits each month, with all features unlocked from the start; those credits reset monthly.

Starter Pack: ₹99 for 100 credits, approximately ₹0.99 per credit. Credits do not expire.
Plus Pack: ₹249 for 300 credits, approximately ₹0.83 per credit. Credits do not expire.

Payments support UPI, bank cards, and net banking, and the website says international credit cards are accepted. A launch offer gives the first 200 registered users 100 credits during their first month. Haru’s public materials do not clearly identify supported platforms or languages beyond the stated website access.

For people who regularly struggle to make workplace messages concise, Haru offers professional-language assistance through a usage-based model. The monthly free allowance makes it possible to try without subscribing, while paid credits remain available without an expiry date.
