FirstSpar
Read full descriptionHide full description
Hard conversations are easier when they aren't the first time you've had them. FirstSpar is a voice-first practice simulator for difficult conversations at work. You say it out loud. An AI counterpart answers back — pushes back, gets defensive, asks the question you weren't ready for — and the conversation keeps going. Your voice is never recorded. No scripts to memorize. No role-play partner required. PRACTICE WHAT HAPPENS AFTER THEY ANSWER Knowing your opening line is the easy part. FirstSpar builds a counterpart from the situation you're actually preparing for — their role, their relationship to you, how they tend to react, and what they are going to disagree with. So you can rehearse the part that goes wrong: - They push back, or go quiet - They get defensive - They question your reasoning - They avoid the issue entirely - They ask the thing you hadn't thought about BUILD IT AROUND YOUR REAL SITUATION Tell FirstSpar who you need to speak with, what has been happening, how they tend to react, and what outcome you need. It turns that into a simulation with that person in it, and you have the conversation out loud. OR START FROM ONE THAT'S READY Over twenty guided scenarios, including: - Giving feedback that won't land well - Managing someone who used to be your peer - A high performer who is becoming the problem - Asking for the raise you keep putting off - An offer that came in lower than you expected - Saying no to more work - Letting someone go - Resigning without burning the bridge - A manager who won't let go GET COACHED AFTER EVERY SPAR When the conversation ends you get a debrief built from what actually happened, not generic advice. - Scored on clarity, empathy, specificity, holding the line and composure - What worked, quoted from your own conversation - One thing to try next time - Your full transcript - How ready you felt before, and after - What to practise next CHOOSE HOW HARD IT PUSHES BACK Practice — some resistance, with room to recover. Realistic — responds the way this person probably would. Pressure Test — challenges you, interrupts, and doesn't make it easy. FirstSpar Pro unlocks Realistic and Pressure Test, longer sessions, and building more conversations of your own. YOUR VOICE IS NEVER RECORDED FirstSpar turns what you say into your counterpart's reply in real time. The audio is never saved or stored. Your transcript and debrief are kept, so you can read back what you said and see whether the practice is working. Because reading advice isn't the same as saying the words out loud. Practice the conversation before it matters. Privacy Policy: https://firstspar.com/privacy Terms of Service: https://firstspar.com/terms
Rehearse

Some conversations you rehearse in your head for a week and still fumble. Rehearse lets you say them out loud first — to someone who answers back. HOW IT WORKS Pick the conversation you have been putting off. Talk to a character who pushes back the way the real person will: the manager who glances at the time, the report who explains before you finish the sentence, the director who restates rather than rethinks. Then get told, specifically, how it landed and what to try next. THIRTY SITUATIONS, WRITTEN FOR A FIRST-TIME MANAGER • Saying no — to your own manager, to a deadline set by a press release, to the same request asked twice • Difficult people — the defensive report, the one who goes over your head, the colleague who will not use the new tools • Feedback — your first critical conversation, telling your boss a target is not real, answering a question about pay • Standing up for your team — one headcount and two teams, the favour that is really a project • Hard moments — the week after layoffs, a report asking about AI, enforcing a policy you did not choose, someone good who just resigned OR WRITE YOUR OWN Describe the conversation you are dreading and the person you are having it with. Say when it is happening, and it counts down to the day. A CARD TO TAKE IN WITH YOU Every rehearsal writes one: your opening line, the thing you will not trade away, and what to say to the three ways they are most likely to push back. Open it outside the room. THEN THE PART NOTHING ELSE DOES On the day, Rehearse asks about the REAL conversation — not the rehearsal. Whatever you learned comes back as coaching the next time you practise it. VOICE OR FACE TO FACE Talk by voice anywhere, or switch on a lifelike, lip-synced face that reacts while you speak. Voice costs a fifth of the credits. WHAT YOU GET BACK A score out of 100, four dimensions scored out of five, the full transcript, and badges that track how much you have practised — never what you practised. Credits are the only limit. Every scenario is open to everyone. Subscriptions (Voice, Pro, Coach) renew automatically every month or year until cancelled. Payment is charged to your Apple ID when you confirm the purchase. Cancel any time in Settings → your name → Subscriptions, at least 24 hours before the current period ends.

Verdict
FirstSpar and Rehearse are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
